  1. I understand you saying postprocessing does the job, and it does fine with your script! However, I do feel this is just patching the flaws of the tool, instead, the developers should have made inserting these codes optional / controllable. The fact that a G-code repeats itself in the file doesn't hint to a well thought out design. As I've been using Marlin and start G-code from within Cura I never noticed this. Now that Klipper is handling all stuff prior to the actual start of the print, I noticed these generated G-codes which interfere with properly controlling the reset and retraction. I do still think that Cura is a great tool, but like other tools, you have to live with the drawbacks. Luckily your solution provides the solution to my question.
  2. Exactly as I was thinking on my way back in the traffic jam... Use Search and Replace with RegEx. I have tried your Search and Replace version which is much better than the default Search and Replace post processing script. This works as a charm! 🙏I replaced the G-code with comment characters to line it up nicely in WinMerge: @GregValiant many thanks for your support!
  3. Thanks @GregValiant for your insights on the retraction G-code addition! I think that the only solution will be postprocessing... I'll try to see if I can create a custom post processor to remove/comment the 3 lines. Shouldn't be that difficult as it appears in the beginning of the G-code file and is a double "G92 E0" entry. Too bad that these codes are added and there isn't a way to prevent them being inserted.
  4. Where did you think the ; Extruder 1 Start G-code comes from? That is in the extruder start code nothing else, as explained in the first post. I'm inquiring about the codes around it, I never added these in any custom start G-code. They shouldn't be there, so what option triggers adding these? E.g. when you have a build volume heater, it also adds a M141 G-code! Would be a waist of nearly 10 years using Cura on various machines (UM3E, home-build bed slingers and CoreXY printers) to have to step over to PrusaSlicer or an equivalent... I always loved using Cura with Marlin based printers.
  5. Similar to Cura adds code before printer start g-code Cura also adds code after the Start G-code section (and also after the tool Start G-code). I've recently moved from Marlin to Klipper, which as a programmer seems very impressive what you can do with macros. Instead of specifying machine Start G-code in Cura you can develop your own script in the Klipper machine configuration. Hence I only need to call my Klipper Start G-code with: START_PRINT BED_TEMP={material_bed_temperature_layer_0} EXTRUDER_TEMP={material_print_temperature_layer_0} NOZZLE_SIZE={machine_nozzle_size} Everthing before the start of the print is handeld by Klipper: homing, positioning, heating, purging, etc. However, I see Cura adds G-codes I do not want, see e.g. the folowing G-code: ;FLAVOR:Marlin ;TIME:16 ;Filament used: 0.00714801m ;Layer height: 0.2 ;MINX:1.2 ;MINY:50.3 ;MINZ:0.2 ;MAXX:1.8 ;MAXY:249.7 ;MAXZ:0.2 ;TARGET_MACHINE.NAME:Unknown ;Generated with Cura_SteamEngine 5.9.0 M82 ;absolute extrusion mode START_PRINT BED_TEMP=70.0 EXTRUDER_TEMP=240.0 NOZZLE_SIZE=0.6 G92 E0 ; Extruder 1 Start G-code G92 E0 G1 F2100 E-5 ;LAYER_COUNT:1 ;LAYER:0 M107 ;MESH:PrimeLine_1.2x200x0.25.stl G0 F2880 X1.2 Y50.3 Z0.2 ;TYPE:WALL-OUTER Clearly, after the Start G-code inclusion, Cura adds "G92 E0", then the tool Start G-code is inserted (only a comment for demonstration purposes): "; Extruder 1 Start G-code", then Cura adds another "G92 E0" and a filament retraction "G1 F2100 E-5". How do I prevent these 3 extra codes to be generated?
  6. After a few years of usage, the LCD display seems to have burn damage of being too much time idling in the main menu screen. I've seen the LCD modules for sale. Has anybody ever exchanged the LCD themselves? My question is if the LCD is easily changed and if there are some instructions to be found.
  7. I think the comment was posted aiming to the OP who got a replacement for free, it is supposed to be sarcastic/funny. Why replace when you get a free core. But, indeed, from economical/environmental point of view it is better to replace parts. Note that there are shops that refurbish cores, you send in the core and get a replacement (actually you receive the core first and a return label for the broken core).
  8. My printer uses 2.85 mm to share filament with the UM3E. I'll look if the diameter of the filament is accidentally set to something different than 2.85. Thanks for pointing to this possibility! edit: Indeed, the filament diameter has somehow accidentally changed... Many thanks for pointing to the correct direction!
  9. No, there is one UM3E stored in the cloud, but that printer is at a different site, furthermore it wasn't even added to this instance of Cura as I wasn't logged in. In a last resort I've removed all appdata and installed versions of Cura and started fresh with a new 4.7 install. The market place has no added plugins (as it should), after adding ColorFabb and Eastman, they simply don't show up in the materials list. Strange thing is that it used to work in 4.6, I even added a set of my own material profiles, but I noticed prior to updating to 4.7 that the materials where suddenly missing. With a clean install, and deleted data I would expect that it would work.
  10. Materials I added myself or downloaded from the marketplace (e.g. Eastman Amphora or ColorFabb) do not show up in Cura 4.7. Anybody experienced similar problems or knows how to fix it?
  11. I have installed the 4.4 Beta. I'm able to re-establish the connection with the printer and can print again. Thanks for your help! Note that 4.3.0 did work for our other department on their UM3E and UM5S, but somehow not on our identical UMS3.
  12. No problem to test it out, PM me for a pre public release (if necessary). Another department at work have a 3E and an S5, so I can ask them to also test if possible (I believe they are still on 4.2).
  13. My Cura 4.3.0 keeps crashing on me just after the GUI has loaded (my apologies to the Cura development team for reporting so much crashes...). Removing all the files from local and roaming gets me further, I get into selecting a printer and see that it fails there. If I select the printer from the network (Ultimaker 3 Extended) the program crashes, but when I select the same printer from the list, Cura continues. Have not tried to print anything as I lost all material profiles. Anyone experiencing the same issue? How to proceed further to connect the network printer? This window pops up when I connect the network printer:
  14. That is definitely an answer! And a great reference for those who seek the same. I guess this should all be done in a post processing script of your own.
