  1. Hey everyone. @Enigma_M4 @fbrc8-erin @3dprintz I've successfully upgraded to S5 feeders on my UM3 with instructions from CarloK. I've put together a detailed write-up for making the upgrades. The doc is still a WIP and I'll be adding more photos, but thought this would be nice if anyone is adventurous. I've been testing it for two weeks a now and so far so good! It gives abrasion resistant feeders and flow sensor. Also the S5 feeder is just way nicer to change filament using the new lever system. The spring lever system of the stock UM3 is so poor in comparison. NOTE: This document is still a WIP. There may be typos or small mistakes. Please do this mod at your own discretion! Its very simple but it does require one small modification to the ultimaker case, so it may void warranty if that matters to you. More photos will be added in the coming days. Also if you spot any errors in the doc let me know. https://docs.google.com/document/d/1xS30mssCCnmrijWDpg-YsJSjPGnsYNUsdmtQHAISqxY/edit?usp=sharing I can also make a new post if everyone feels that this is worthwhile.
  2. This is a project by a group of community members which was also involved in the Mark2 dual extrusion upgrade. More precisely, it's me coming up with an outside the box approach / weird idea for a certain unresolved problem. Smart people like @gr5, @Anders Olsson, @Dim3nsioneer, @rooiejoris throwing in ideas and @tinkergnome who implants the stuff into firmware. My impression of the current state of development when I started this was as follows. There have been filament monitor projects since the beginning of reprap. Only very few made it to some kind of product state, like the one by Aaron Tunell. Manufacturers like Prusa and others recently introduced some kind of filament monitors, with mixed success / reliability issues. The Duet3D guys set their hardware research (laser-based and rotating) on hold because they were experiencing inaccuracies of +/-20%. Well and then there was Ultimaker ... until yesterday with the S5 All these efforts have been or still are struggling to fulfill the most important objective: NO FALSE ALERTS. Otherwise any filament sensor would quickly render itself useless. What we want to achieve Objectives, the obvious part: zero false alerts detect filament runout ("nothing there") detect filament grinding ("nothing/very little moves") Objectives, the challenging part: detect first layer issues (see video below) detect when real flow leaves a certain safe process window and starts to compromise part quality (first, inter layer adhesion will suffer, then classical under extrusion will be visible) and try to counteract, that's where the real fun starts ... Current state of development We chose an encoder and there's a reliably working prototype for an easy to attach external flow sensor, mounted to the entry side of the feeder. Resolution is in the range of 0.015 mm. It's integrated in Tinkerware with a dedicated menu and we (well, he) implemented a gcode command: M591 T0 S1 E0.5000 L0.01695 R35:130 A0.3 P100.00 I leave the parameter interpretation as a little quiz here. Right now I'm working on a modified design which, besides the encoder, doesn't need some parts which cannot be printed and are in the +30€ range to have them manufactured. But most likely some parts will still not be FFF printable. How can I get this? First give us some more time to test and evaluate. If everything works like intended we might proceed like with the Mark2 project. If we should offer this as a product I'd expect a price tag between 70-100 €. And the UM3? That's the BIG question. Like @Daid recently stated their main market is already different. And indeed, has anyone seen any kind of (hardware) upgrade for the UM3 so far? Feeders are the same, mechanically our sensor fits. Electronics, not sure. Ultimaker originally wanted to use a serial interface on the UM3. For the UM2+ we simply connect the sensor's quadrature output signal to free I/O pins, there are enough left (4) for two sensors for a Mark2 dual extrusion UM2. Ultimaker won't do anything to support a sensor on the UM3. Anyway, if a large number of UM3 users would show interest, they might at least not impede a development ...
  3. I'm running Marlin 1.1.8 on my UMO with its original 1.5.7 electronics and an Ulticontroller. I've been building a new version of Marlin 1.1.8 for my Bltouch sensor, which I'm about to hook-up and start testing. The Marlin source code says: // Enable this feature if all enabled endstop pins are interrupt-capable. // This will remove the need to poll the interrupt pins, saving many CPU cycles. //#define ENDSTOP_INTERRUPTS_FEATURE and the Antclabs Bltouch instructions say this feature is optional. Does the 1.5.7 board have at least three interrupt-capable inputs? I only need three inputs because the Bltouch will use one input and provide a Z homing signal so that means I need only two more endstop interrupts for X and Y. Software limits works fine so I don't need MAX_PIN inputs as defined in the pins.ULTIMAKER.h file defaults here: // Limit Switches // #define X_MIN_PIN 22 #define X_MAX_PIN 24 #define Y_MIN_PIN 26 #define Y_MAX_PIN 28 #define Z_MIN_PIN 30 #define Z_MAX_PIN 32 Even though it would be inconvenient to adapt the endstop switch connectors, they could perhaps be connected to pins 11, 12, 13 or maybe even pins 34 and 36, which are labeled "SERVOS" on the PCB silkscreen. I plan to connect my Bltouch control (servo) pin to pin 13 and it seems that pins 11, 12, and 13 are usually used for such things. Also from pins.ULTIMAKER.h: // // Servos // #define SERVO0_PIN 13 // untested Does anyone here have experience with this? Did using interrupts work well (better than the default CPU polling)? Once I get it up and running and tested, I'll fork the Marlin 1.1.8 source (or maybe I'll spin-up 1.1.9, which is the last 1.x.x Marlin, except for bug fixes) to my github account so others can give it a whirl. BTW, this Bltouch V.2 mount looks pretty good to me. There's not all that much info on the Internet about this UMO mod or endstop interrupts. Bltouch Mount Same as above but with Google Translate to English Thanks!
  4. Mark2 is an asymmetrical multi-extrusion upgrade for the Ultimaker 2, based on Foehnsturm's magnetic tool changer. It offers some unique features compared to conventional approaches. Keep it smart and simple The Mark2 upgrade doesn't require to modify or even disassemble the well-working single extrusion setup. Instead it adds a detachable second extruder. This leaves you with several benefits. Powerful - print quality on par with eg. the UM3 or BCN3D Sigma Flexible - use whatever you want: Olsson ruby, 3Dsolex block / nozzles, ... Cost-efficient - all you need is a second drive train, some magnets and screws Simple - all tried-and tested standard components Smart - Z-offset managed by firmware, calibration wizards Open & scalable - a non-extrusion tool head, a 3rd extruder ... all possible Mark2 is an Ultimaker community project, we don't offer a complete kit but we can help you out with a package, including all the parts you need, besides the second drive train. See it live Probably the best way to get an impression of the usability and print quality is to watch a few videos. https://www.youtube.com/watch?v=PLeNzDYMnqAqIeZHWU9iOWnj_2OaemupQG Full Cura 2.5 integration Mark2 comes with a set of Cura definition files and can be added as a pre-configured printer. Tried and tested Mark2 setups have been printing for more than 5.000 hrs now, which equals more than 500.000 tool changes. Beta-testers and co-developers include well-known guys here like Tinkergnome, Ultiarjan and many more. The Mark2 website ultimaker-mark2.com is the place where you find all the information you need for doing this upgrade. ... and The Mark2 Dual Extrusion Project Contest is still running.
  5. Hey guys, I would like to share a lever action dual extrusion solution I came up with for Ultimaker 2+. The approach is based on the great effort everyone put into Mark2 and Ultimaker 3. The print head holds two hot ends, which are originally to be installed on standard UM2 head for 1.75 filament. The right nozzle move up and down for nozzle swapping. This compact dual print head can achieve single extrusion print area of 220x223x205, and dual extrusion print area of 202x223x200. Video clips: Files and instructions available at: https://github.com/yyh1002/DXU Credits: Lever lifting mechanism is inspired by Ultimaker 3. The firmware is modified based on Mark2 version of Tinkergnome firmware by @tinkergnome. CURA profiles are modified based on the Mark2 profiles by @tinkergnome and @foehnsturm. Used Mark2Tweaks plugin for CURA by Krys Lawrence.
  6. I was looking into a way to occasionally print Ninjaflex or other real flexible materials (85A) There's no way you'll be doing that reliable with a bowden setup (ok, I've seen people using oil in the bowden but nahhh), so I compared a quick and dirty direct drive conversion on an Ultimaker2 head (tested on my DIY GO) and on the ultimaker S5 **** first a warning, Ultimaker does NOT want you to open the S5, it contains an open style high voltage power supply, so it's DANGEROUS!!!, also the electronics can be damaged and I'm pretty sure you loose your warranty. **** I used two materials for testing, Extrudr TPU Soft and Ninjaflex, both 85A. I used the regular feeder from the UM2+ , combined with a pancake stepper motor (LDO-42STH25-1404MAC#190920) this stepper is less than half the weight of the normal stepper. I had to cut some length of the shaft to make it fit. The stepper has a different # steps per rotation and as it's impossible to change the steps setting for the S5 on one feeder it needs compensation in flow (200% flow = 100%) Obviously the result is a crazy top heavy setup, but if you just want to print an occasional gasket it should be fine, specially since you need to print materials this flexible very slow (15 mm/s) anyhow. On an Ultimaker2 the extra weight is enormous, on the S5 not so much as it's very heavy already anyhow. The nice thing is you can see into the feeder so during testing it's easy to spot when the feeder can't cope if you try to speed it up to much. If something goes wrong it's mainly during the first few layers, so watch them... otherwise you'll spend a few minutes again taking the feeder apart... To validate the basic setup I printed regular PLA on both converted machines, to make sure the setup (including changed steps/flow due to different motor) was correct. On the UM2 head the ninjaflex was pretty easy to get working, i managed to print with constant and reliable extrusion using a 0.4 nozzle. The materials prints best around (I tested with 0.15 layers) Flow : 110-115 % (with feeder tension set to lowest point) Temperature : 210 c Speed : 15 to 20 mm/s The easiest way to test temperature and flow is by printing simple cilinders, foir the S5 you can use the "tune" menu to play with values on the fly. Getting ninjaflex to work on the S5 proved to be more difficult than on the UM2, at the same settings using an 0.4 mm nozzle prints failed all the time, it seems the CORE, is much more of a challenge that a UM2 setup. I blame the longer filament path, and the metal tube of the core. Only when I changed to the 0.8 nozzle and the CC0.6 I was able to get reliable results. My main S5 tests are with the CC0.6, atm my best results are with the following settings; The S5 levels pretty close to the bed, making every print fail at normal flow rates. Layer height 0,15 Initial layer height 0,25 Top/bottom pattern & Innitial layer pattern ; concentric (avoid lot's of small lines, head vibration) Innitial printing temperature/ innitial layer : 230c Printing teperature : 215c Skirt/Brim flow 140% (= realy 70%, due to the different stepper motor) Innitial layer flow 150% (= realy 75%, due to the different stepper motor) Flow 225% (= 2x the real flow, due to the different stepper motor) Print speed 15 mm/s Innitial layer speed, Skirt/Brim speed 10mm/s Cooling at 100%, start with 20% and let it rise over 10 layers) Turn off the flow sensor (in the settings menu) on the S5, as you're not using that feeder.. Conclusion, even if you eliminate the bowden, printing 85A flex on an Ultimaker S5 is still a bit of a challenge. The used feeder (UM2+UM3 model) and filament path are not ideal. But, usually if you make it past the first few layers, and have relatively simple prints that keep the flow going it's very well possible to print ninjaflex on the S5. I have not experimented a lot with it jet, but I also managed a simple test print using PLA for support on the 2th extruder. the hardware hack; The feeder plate mounts to 3 screws of the head, so you can leave one and the head will stay assembled during mounting. I made a little breakout plug for the left stepper motor on the back of the printer, so I can change between direct and bowden in just a few minutes. I just leave the black mounting plate on the head. In needed to make a hole in the bottom plate for the DIY extension cable. I isolated the plug with hot glue. some side notes; Cura can sometimes create fantastic vibrator g-codes, not nice with this heavy setup, so one thing you can do to prevent this is to change line fill to cylindrical fill, and check the layer preview. ninjaflex openRC wheel, printed on S5 extrudr TPU soft (85A just like ninjaflex) gasket, printed on S5 S5 stl's S5_FlexDirect.zip
  7. I am looking to print ABS w my S3. I also have a UM 2+ that has a top cover that has been working very well when printing ABS. I would like one for my S3. UM2 + Extended Frame Top Cover I have found only two covers: FBRC8 ULTIMAKER S3 SAFETY ENCLOSURE KIT 3D JAKE Cover + Door incl. HEPA Filter for the Ultimaker 3 Experiences, suggestions, thoughts? Thanks
  8. I recently purchased an Ultimaker S3 and so far have been blown away with the quality of the prints. Thus far I have only used the provided glass heating bed for all my prints and as a result my bottom layer is always very shiny and smooth. I am now trying to get a more matte and textured look on my first layer. I was wondering if anyone had any suggestions or 3rd party heat beds that I can use to get this effect. I was told that by putting some blue painters tape on the heat bed I could possibly get this to work. Any suggestions would be greatly appreciated!
  9. Hi all, I need some help with a UM2E+ with Tinkerware and Bondetch DDG for Octoprint. What settings go into the individual bounding box ? Or does anyone have a working profile for the Ultimaker ? The Problem is : The Problem exists at the start and that is : All axes move up X Y moves to the front left Z axis moves to the top Material is extruded but exactly on the clamp at the front and not on the bed. Now the actual printing starts. Whats the Problem? THX for Help! stay healthy !
  10. Here are a few of the projects I've worked on using the Ultimaker 2+ There are 3 select fire blasters, and the pump blaster is a pistol grip conversion. The OLED mount with rail on the back are printed The battery cover in the front grip is a printed part along with some internal pieces Stock extension and top rail are printed Masterkey is printed Stock extension and handle fill with knobs are printed Pump grip and main grip along with trigger are printed
  11. I recently built a new printer and hate the idea of my old UMO+ just sitting around or turning to waste. Is it possible to repurpose the ATMEGA 2560 based controller for something like a low powered laser cutter? Will the firmware for an ATMEGA 2560+ RAMPS 1.4 also work for the UMO+ controller?
  12. Hi, I am wondering if there is a workaround that you have already done that allows me to upgrade my existing printbed that is reaching now max 98c. Right now I am experiencing too much fails with PC and ABS and I am 100% sure that part of the problem is the printbedtemp. Prints are comming out great until the print jumps a ceratain hight the warping starts and after 1 cm it becomes hilarious. So I have to get a workaround if I ever want to use theese materials in a good way. So I am looking for a replacement of the existing printbedheater and or maybe to adapt an S3 printbed which would be already somewhat better with 130c° max heat Any idea that is feasible would be appreciated.. Greetings and stay save! Daniel
  13. Hallo, ich hätte mal eine etwas verückte aber dennoch interesante Frage, Drucker S5 ich habe einen alten 0,25Core, so meine Idee wäre daraus eine sag ich mal 2mm Düse zu machen. in Cura würde ich alles auf die 2mm Düsenbreite eingeben und auch die schichtdicke und alles so anpassen, das es eben auf die größe passt. Das würde ja Theoretisch gehen oder? Praxis ist dann wieder etwas anderes. 😄 Hat sowas schon mal jemand gemacht
  14. Hello everyone, I have recently started to use Octoprint on my ultimaker 2+ and I really love it. I have also like a lot the timelapse that is possible to create with the Octolapse plugin specially yhe famous one without head movement! Unfortunately I haven't found anyone sharing setting for the Ultimaker 2+ (open firmware) I was wondering if anyone had experience yet! Many thanks in advance! Emaunuele
  15. Hallo, Habe vor kurzem dem den ganzen Druckkopf ersetzz. Jetzt zeig er mir diese Nachricht an. Kern 1: Solex Hardcore 0.4 Kern 2: Solex Hardcore 0.4 Danke schon mal
  16. So I'm looking into getting the mmu for my printer, so I decided to go ahead and get the profile set up. Here's where my problem starts. So basically I just copied the original profile in the definitions folder, but I just added extruders, that is literally the only different I made, besides just a few name changes( i tried it with the original stuff and it didn't work either). Keep in mind I already set up more extruder profiles. Whenever I try to boot up cura it'll say that the files are corrupt. I've gone through multiple forums and cant find anything. Here are the files, is there anything I can do? Prusa MMU Profiles.zip
  17. Hello together, after building a custom custom frame for an UM2 Link and make several test's with dual printing system's, I decided to make a test with an Cyclops extruder clone. At first I started with the firmware because i will use only 1 heater and only an resistor from the tempsensor of the second unused heater. What's done for the moment? - Printing: GCODE hotend changed with M104 and M109 changes every time the temperature of the hotend 0 independently of the temperature is set for E0 or E1. In the picture you can see that heater 1 is heating und steps of heater 2 changes - Cleaning print menu Temperatur 2 is removed but material flow 1 and 2 are still available - Material change for second nozzle changed, now it heat's hotend 1 with the temperature of the material 2 - Changing the function of advanced maintence At first step i changed the function of heatup of the second nozzle. Changing this temp changes the temp of the first heater. - Changing the function move material 2 in advanced maintence If it's selected it changes the temp of hotend 1 with the temp of material 2 and when the temp ist arrived I can move the material 2 (E2) - Build a Cura 3.3.1 printer configuration (I modified the config of Link) What are the next steps? - Finishing the cleaning of advanced maintence (remove heatup secondary nozzle, it's a little big trickier as I thought) - Check if it's possible to deactivate the error for the missing Tempsensor, if not a potentiometer should work great ? - Build and mod the printer, make test's and show the finished build here (parts are ordered and I'm waiting) ? - Show the prints here and on my homepage - Make a documentation of the build (mod), will publish the documentation here @ SeoGeo_de - Publish the Marlin code on Github Needed parts: - Change filament size to 1.75 mm - 2 new extruder requiered with 1.75 mm support - 1 new Steppermotor for E2 - Cyclops V2 printhead and a few small parts At last known issues / specification - GCODE has to be Marlincode, with Ultimaker code it don't work (for me no problem because I use octoprint) - I can't check in Marlin if the GCODE sent temp is the print temp or the standby temp, so I have to set for the standbytemp the printing temp of the other material. Example: Extruder 1 PLA Extruder 2 ABS Print temp 200°C 240°C Standbay temp 240°C 200°C If somebody know how I can detect if the send temp is printtemp or standbytemp, this step can be ignored - Change the filament size to 1.75 mm (I didn't found an Cyclops with 2.85 mm) If somebody have questions or can help me with my issues, please answer here or write me a pm. Sorry for my english I hope all can understand what i have wrote. Bye Daniel
  18. I have a ultimaker from before 2017 meaning that i have 5 motor drivers. I have the mark 2 kit installed meaning that i have used all 5 motor drivers. If I wanted to add another motor for another extruder, how would i go about that? Thanks
  19. I never thought i would be saying this but im having underextusion issues on my um2 with a bondtech qr extruder. I think its a problem with the firmware though. I prefer tinker firmware so i am using that instead of the bondtech firmware. I think its a problem with the esteps value. Ive tried "printing" a gcode file with the Esteps command and also pronterface but both don't seem to work. Is there a way to directly check if the esteps value was uploaded and saved? Or is there way i can modify tinker firmware and change the esteps value and the loading speed? Or am i doing something completely wrong? Esteps value:492.45 loading and unloading speed 50mm/s
  20. Is there a benefit to printing more abrasive materials than the standard materials? What extruders do people like? I see lots of discussions on Bondtech. I am a bit concerned that printing will be more complicated with the necessary speed changes in my printer. Is there any benefit to using a CC ruby printcore?
  21. Can anyone with experience in using octoprint on the UM2 lead me to a good source for a tutorial on how to install octoprint? Many resources out there are kinda old. Any help is appreciated. Also If you have installed octoprint, could you tell me what hardware you needed(especially the wifi dongle). I have a raspberry pi 4b 4gb ram model. Thanks!
  22. Hi Which dual extrusion mod for the UM2+ would you recommend? The Mark2 or the DXU, or something else, and why would you recommend that particular one? Thanks!
  23. I have a UM2 and I want to buy another Bondtech Qr feeder. https://www.matterhackers.com/store/l/bondtech-qr-extruder/sk/M4KZR03V Will this one work? Its not part of the Ultimaker 2 upgrade kit, so I wasn't sure if it would fit. It doesn't include the 3d printed parts so I can just 3d print those. I can also just buy the nuts and bolts but can I just use the same stepper motor wiring I use for my current extruder?
  24. I recently got a new bondtech feeder and changed the heater(25w) and sensor on my um2 to the ones for the um2+(35w). How do I modify my firmware to match these modifications.
  25. Hallo, Was soll ich jetzt am besten machen. Material: PETG Extruder 1
