Ultimaker 2 with cyclops (dual print with single nozzle)


Recommended Posts

Posted (edited) · Ultimaker 2 with cyclops (dual print with single nozzle)

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)

Cura.thumb.jpg.a4481d4f8df556af3f2c15a3ab77d317.jpg

 

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

    Hi Daniel, interesting project!

     

    I am upgrading my UMO+ with an dual extrusion system from E3D, too. But I‘ll use the Chimera+ instead of the Cyclops+. However unfortunately there are no 3mm versions - I hate that.

    I won‘t switch to 1.75mm filament because I still have tons of 3mm spools and buying two new extruders is probably more expensive than modifying the Chimera/Cyclops to a 3mm version as I will do.

    You „just“ have to drill and glue a bit and buy new custom made 3mm version heatbreaks (that‘s the expensive part but you can even make those heatbreaks out of a better titan alloy).

     

    Have a look at my post in the german forums: 

     

    There‘s a picture on the 2nd page what has to modified.

     

    Just to give you an alternative to consider. It‘s up to you.

    Hi,

    But I have order all parts for the printer new. 

    I start fresh with 1.75 and have to buy new filament, but yes if it's possible to change modify the extruder it's also a possibility.

    And for me one possible aspect is I can test filament from friends they use all 1.75.

    The only what had to be changed is the steps for the extruder.

     

    And in German:

    "Danke für den Tipp, hätte ich vielleicht vorher schauen können ? Grüße aus BW"

    Update for today:

    Advanced menu is finished and I think I found where I can deactivate the second temp sensor, but I have to wait for the hardware to test it.

    Move material for both extruders and heatup nozzle only for 1 heater.

    Hello, 

    today I get my printhead.

    @  my homepage www.SeoGeo.de I beginned te build, but I will not talk about the clonebuild here.

    There a picture of the printhead and the frame of the new printer.

    It seems that the firmware works. 

    I was able to start without temp error in dual extrusion with only 1 tempsonsor ?

    There are two tempsonsor connect temp1 and the heated bed.

    If I have enough time, tomorrow I will start my first print.

    It was a very long step to show this but now I can show my first dual prints with 1 temp sensor and 1 heater.

    The printquality is not the best because the temperature is not stable or the difference is to big between both colours. The reason is that normally there have to be a 6*30mm heater but I only have a 6*16mm. But I think I will get the right heater soon.

    But here my first 2 videos:

    Nice and clean setup!

    How much wattage does the heater cartridge have (or will the new one have)? I would buy a strong one. Probably 60 Watt or more because the hot end is quite big.

    At first I will start with 40w, I didn't found one with more watts. 

    Do you know a German reseller that sell this?

    I couln‘t find a german reseller who sells 60W cartridges either but there are some chinese reseller. Dyze offers a 60W 24V cartridge too.

    Tonight I have to look for the actual mounted heater. At the moment it's mounted on one site so the 2 extrusion is good no dropping or anything and the side with the heater is to hot and the heat hears the filament in the tube

    After having a lot of trouble with the temperature of the Cyclops clone and for me personally the um2 printhead is a great printhead I give it a try.

    And after a little bit of Testing I can say it look like it works.

    Take a look to the video and good night

    At the moment I´m making print test. 

    For example I found an error in M140 code for the heated bed (I erased a line to much ?).

    For the moment the decision to change from Cyclops clone to um2 printhead was a great decision.

    Pro

    - No temperature problems like i had with cyclops clone

    - Cheaper like with cyclopse

    - If somebody will build this, he needs only a stepper-motor, an 2nd extruder and little bit of ptfe tube.

      If somebody make an y adapter, splitter or how ever its called, for 3 mm it should work with your actual setup and don´t have to change to 1.75 mm

    I used this Y adapter from thingiverse

    Thingiverse

    Con

    - it looks like I have to extrude more material to change the color like with the cyclopse

    - switching the material takes a little bit longer

    - I need to make a toolstart and stop script in Cura

    - I need to add in maintance a menu to change the selected extruder

     

    Actual i´m printing the dual frog, here a few pictures of the setup (build) and the print. Tomorrow i will post a new print video and pictures of the frog.

    The first real dual print is finished, I had 2 times a switching problem with the black colour. Tonight I will check why. 

    Here a few pictures. I'm really happy. Now I will make print  test's until end of next week and then go to vacation. Here I will write a how to and relaese it as beta here.

    Now a few pictures

    Here also a detailed picture of the printquality.

    It's printhead with 0.15mm layer height

    Hi,

    here is the video to the print. 

    I'm near to release the first software on Github.

    I have read several times, I wanted to use a double engine and single extruder system for some time. But I did not understand what changes to the firmware I have to make. I use the Tinker custom firmware.
    Thank you so much, and congratulations.

    Hi fcassulo,

     

    the change is not only a change in the configuration.h.

    It's a lot more you have to change a lot of things. the biggest problem is to get it work without the second PT100.

     

    But it don't take long for the SW release.

    I have a working alpha Version and finishing the release Version where you can choose if you work with Cyclopse or with Y adapter to make the Filament Change und set the height of retract if you have an Y-Adapter but it takes a little bit, I'm milling a big project for my wife in the living room and for the "WAF" it's important to do this first 🙂

     

    The SW works and I'm finishing it release will come soon.

     

    Best wishes Daniel

    I would opt for the Y solution. Then I'm waiting. Congratulations again.

    Hi,

     

    Can you go into a little more detail (if you still have it) of what you did to that um2s-marlin firmware to get it to work?

     

    Thanks,

    Bigrjsuto
