    Timelapse mit Ausloeseknopf ...

    Hübsch - aber Vorsicht mit dem G92 E0 am Anfang: Das sollte nicht notwendig sein, wenn sowieso relative Koordinaten benutzt werden. Das stört nur deshalb im Moment nicht, weil "Allow zeroing extrusion distances" aktiviert ist, stellt aber eine weitere Abhängigkeit von den gewählten gcode-Optionen dar. Wenn ich das richtig verstanden habe, kümmert sich "Octolapse" zusätzlich darum, das die Foto-Pause möglichst nicht beim Drucken der äußeren Wände passiert, sondern z.B. in einer Infill-Section - da stört der Blob dann nicht so. Das ist mit einem einfachen Layer-Change Skript aber nicht zu machen.

    Submitting a new Printer Definition

    Are you familiar with git and/or GitHub? The instruction on the wiki page says: Source: https://github.com/Ultimaker/Cura/wiki/Adding-new-machine-profiles-to-Cura

    Timelapse mit Ausloeseknopf ...

    Gerd hat Dir ja schon die richtigen Hinweise für das Skript gegeben. Man kann im Skript nicht rechnen, deswegen musst Du beim retract mit relativen Bewegungen arbeiten: M83 G1 E-[retract_distance] F[retract_speed] ; retract M82 ...aber am Ende vom Skript musst Du den Retract auch wieder rückgängig machen, das fehlt irgendwie noch: ... G1 X[next_position_x] Y[next_position_y] F9000 M83 G1 E[retract_distance] F[retract_speed] ; undo retract M82 Das funktioniert so aber nur (bzw. ist nur notwendig), wenn die gcode-Option "Relative extrusion distances" im "Normalbetrieb" ausgeschaltet ist. Das scheint bei Dir aber der Fall zu sein.
  4. Sigh... Yes... and.... yes. (but you'll probably do not gain much - compared to the "Extra fine" profile) Consider the Cura profiles as some presets that are well suited for the most common cases. There's no specific preset for 0.04 either, none for 0.08, none for 0.12, none for 0.18, 0.03 and 0.19 are missing as well .... you get the idea...? 😏

    3D Printer not printing properly

    Sigh... First of all: Sketchup is not well suited as a modeler for 3D printing. You should really consider a different modeling program... If you want to stick with it: start with removing all superfluous inner faces, here are just a few: There should be an "outer shell" tool that can be helpful
  7. Simplify3D does not include this nice "standby temperature automatic" (like Cura). Besides that it works just fine with the Mark2 setup. I see no reason why you should not use ABS, as long as you get dimensional correct prints with it. Insert the magnets with a drop of epoxy and you're good to go.
  8. Thanks - good to know. The tooltip says it will print walls that are thinner than the nozzle diameter. That's a different feature (in my understanding), that's why i have not tried it yet.

    Cura disables extruder heating during print

    There is a reason: Cura disables the heater for any tool that is not longer used for the print. I guess the remaining 40 layers are printed with T1, and T0 is not longer used. That's why Cura disables the heater for T0. This is regularly a problem for printers with multi extrusion, but single nozzle and can perhaps be changed with a postprocessing script, but i don't know if such a thing already exists. I really think this should be properly handled by the firmware of those printers. If it doesn't - it's a firmware bug, not the slicers fault (IMHO)

    Has any other thing changed between the two prints? Both prints are started from the sdcard via the printers menu?
  11. True of course. But personally i would kindly ask my favorite Cura contributor if he is willing to implement a "Allow single extrusion for thin walls" feature into the CuraEngine... 😛
  12. ....or perhaps: model a solid rectangle (without holes), in Cura choose a wall line count of 1, zero top layers and zero infill. Should also print nicely.

    Dynamic vs static IP address

    I can make some experiments tomorrow, but first some thoughts... if you connect it with a cable you should get the LAN service-name listed the LAN connection should even work without a router by using a cross-link cable between a PC and the printer (i'm not sure, if a cross-link cable is still needed nowadays - probably a normal cable would work too) on the other hand: all you need is probably the servicename of the ethernet connection, but i don't know, if it can be configured while it is disabled? the service name for a cable connection is usually "ethernet_<MAC-address>_cable" there's a folder for each configured connection in "/var/lib/connman" that corresponds to the service names, to check: ls -d /var/lib/connman/*/ or use "ifconfig -a" to determine the MAC-address for eth0 and insert it in the service name (without colons and brackets)

    Z travel is going wrong way.

    Well... the gcode that is generated by the slicer only contains the target coordinates, no moving directions. The comment ("lower build plate") is only valid for printers where the buildplate moves down though... but comments don't matter. Printers usually don't support negative coordinates, so there is no way to move the z axis "through the buildplate" to a negative coordinate - but your device may be different? How does the homing sequence and the calibration of the z-position work e.g.? If your custom printer needs a different start script: you can modify it in the machine settings (in Cura). Everything else is a task of the firmware / hardware of your printer. If your issue is different - you have to explain a bit more - i guess...?

    Dynamic vs static IP address

    Well, it's still an ugly workaround, but it is not hard. The Linux on the Olimex-board is based on Debian (AFAIK). You have to (temporary) enable the developer mode and you can use the wifi hotspot (that the printer creates if you start the wifi setup) for the ssh connection, if there is no other network option available. The printer uses "connman" for the network setup, here are the steps:

    Unusual Failure

    It has be done before, there are a lot of pictures in this thread:

    System Date & Time ?

    Which kind of printer is this? The UM3 electronics doesn't include a real time clock that you can set manually (AFAIK). I think, it tries to get the system time from an ntp server, if it is connected to a network that allows this (firewalls or a proxy may deny it). The S5 uses the same electronics. It's normal that the printer always starts with 01.01.1970 - no need to worry.

    Unnütze Bewegung vom Druckkopf/Extruder

    Mit Cura nur für Dual-Extrusion, dann aber mit Prime-Tower, ich glaube das macht auch nochmal einen Unterschied. Für alles andere nehm ich Simplify3D - das ist bestimmt auch nicht perfekt, aber damit kommen mein Rechner und ich irgendwie besser klar... 🙂

    Unnütze Bewegung vom Druckkopf/Extruder

    Wenn ich das richtig verstanden habe, hat das einen technischen Hintergrund. Seit in den neueren Versionen die CuraEngine auf "multi-threading" umgebaut wurde, wird jeder Layer einzeln abgearbeitet und der jeweilige Thread kann überhaupt nicht mehr "wissen", wo der vorherige Layer aufgehört hat.... Schöne neue Welt... das slicen geht damit aber angeblich ein paar Sekunden schneller... 🤷‍♂️ Naja, für optimale Verfahrwege war Cura auch vorher schon nicht der richtige Slicer... Evtl. kann mit dem "Z Seam Alignment" noch etwas beeinflusst werden - ich glaube, da gibt es neuerdings auch einen "Relativ-Modus", wo man feste x/y-Koordinaten angeben kann. Ich kenne mich aber mit Cura nicht besonders gut aus.

    Tinker firmware - introduction

    I was asked to sum up some facts about the alternative "tinker" firmware. Here are the basics and the main links to start with it: What is the "Tinker-Firmware"? It's an alternative firmware for machines of the Ultimaker 2 series. The main development was made by me in my spare time. It's open source, based on the standard firmware from Ultimaker, but driven by the community. One of the benefits is that special requirements can potentially be adapted faster. At least there's a good chance that someone 'jumps on the bandwagon' and implements it. The tinker firmware does not work on an Ultimaker Original, but @amedee made an excellent job and offers a free online firmware compiler for these machines: https://bultimaker.bulles.eu/ If you want to learn more about firmware in general (what it does and how it works), you find more information on the homepage of the Marlin Firmware: http://www.marlinfw.org/ What are the differences to the standard firmware? Basically - the user interface. Most of the "driving logic" under the hood is untouched and derived from the Ultimaker standard firmware (and finally from the Marlin firmware). The menu structure of the tinker firmware is intended to support the needs of advanced users and tinkerers. In the beginning I developed it only to fulfil my personal interests, but it began to grow after I shared the result with the community. The initial intention was easier access to the 'tune' options during printing. In addition: more preferences are configurable directly on the printer. For example: the beep on key-press and the printing area can be changed without the need to re-compile. There is also a 'sleep timer' that switches the light off after a configurable period of time. It's unlikely that something on your printer gets damaged by this firmware, but there's no guarantee. You are using it on your own risk. If necessary, you can always re-install former versions (or the standard firmware) with Cura. After a subsequent factory reset all behaves like before. How to get it? At first: be aware that I don't own all printer models by myself. It should work, but each new release should be considered as "untested" until the contrary is reported. Still interested...? The source files and ready-to-use binary files for several variants of Ultimaker 2 and 2+ machines are hosted on GitHub. Just download the appropriate hex-file for your printer and store it on a local drive. The file names should be pretty much self-explanatory: https://github.com/TinkerGnome/Ultimaker2Marlin/releases The hex-file can be installed on the printer with the assistance of Cura. If you own an Ultimaker, you probably have already installed it. If not, you can download the current version of Cura from the Ultimaker site: https://ultimaker.com/en/products/cura-software Within Cura 2.3.x. choose from the menu: "Settings" -> "Printer" -> "Manage Printers" Take care that the active printer is the one that you want to use for the firmware update and connect printer and computer with the USB cable. Click on the button "Upgrade Firmware" and choose the option "Upload custom firmware". Where to get help? There's not much documentation for this alternative firmware yet. Just explore the menu structure on your own... If you have further questions you should ask for assistance on the Ultimaker forum. There are many active and cooperative community members. Please use the original topic from the link below for questions, suggestions and discussion. That helps to keep everything in one place. https://ultimaker.com/en/community/7436-more-information-during-print You can even join the team and contribute by yourself, just offer your skills and ideas there. If you notice a specific issue, you can also report it on the GitHub page: https://github.com/TinkerGnome/Ultimaker2Marlin/issues Have a good time!

    Tinker firmware - introduction

    My first guess is: Check the settings of "Advanced -> Preferences -> Print area"

    Overriding Start G-Code (CURA 4.0.0)

    Basically it should be possible to use the same start script as before, but the names of the settings / replacement patterns have changed. You will probably need: {material_bed_temperature_layer_0} {material_print_temperature_layer_0} {speed_travel_layer_0} If you're interested: @ahoeben compiled a list of all possible variables a while ago: Settings and replacement patterns

    New at this...

    Welcome @ruffnec, a few questions: Do you use the software package for Windows that came with the printer or a different version of Cura? The instructions from Creality are basically: "no driver - use the provided sd-card to print the generated gcode files", does this not work either? For the USB connection on Windows 7 you have to install the provided FTDI drivers, i have no clue what is needed for other operation systems BTW: "Ultimaker 3D printers" is probably the wrong category for this question... wouldn't it be better to move it to the Cura forum?
  24. It's one of the known bugs in version 3.6 and it advertised to be fixed in the next version, see:
