Hi, I'm having an issue with my custom printer configuration. This issue only occurs with .15 (Normal) quality profiles and it is present on all .15 profiles. The issue is the infill speed is calculating incorrectly. Infill speed by default is set to equal speed_print. The speed_print value is set in my quality profiles text files to 200, so infill speed should also be 200 and it is for my .1, .2 and .3 layer height profiles, but not for .15. Instead for .15 I am getting 334 for the infill speed. I have multiple .15 quality profiles for different materials and this issue persists for all. I have tried copying one of the quality profiles that does work into the .15 quality profile with no luck. Possible random coincidence I found. The default print speed is 60. My print speed is 200. ((200/60)*200)/2=333.3333. This probably does mean anything, but something I noticed when trying to figure out why this is happening.

Hi, I'm having an issue with the start gcode for the custom printer definition I'm working on. I need the printer to heat the hotend to the temperature for material 1. However, if multiple materials are being used with different printing temperatures, the highest temperature is set to T0 regardless if that material is assigned to T0. I have copied my start gcode below and bolded the two lines that are causing problems. M98 P/sys/messageprintstart.g M104 S{material_print_temperature_layer_0} T0 ; set extruder temp M140 S{material_bed_temperature_layer_0} ; set bed temp G32 ; home xy M190 S{material_bed_temperature_layer_0} ; wait for bed temp M109 S{material_print_temperature_layer_0} T0; wait for extruder temp M98 P/sys/homeu.g G1 X-12.5 Y0 F6000 ; Position Tool Head for filament change M83 G1 U0 F2000 ; Position filament selector for bay 1 M83 M116

I'm configuring Cura for a new 3D printer my company is developing. The printer has a 3 material set up, which loads and unloads the 3 materials into one hotend. Very similar to the Prusa MMU2.0. My issue is that Cura is adding a M104 command for T2 at the beginning of the print after the start gcode. This is problematic as printing starts with T0, but since the temperature has been changed for T2 and all tools use the same heater, T0 is now printing with the T2 temperature. Hopefully, that makes sense. I have pasted the beginning of my exported gcode to show the issue, the problematic line is in bold.

Okay, thanks for the info! I will look into creating a plugin to handle this.

I'm trying to set up profiles for a custom printer I am developing and am running into an issue with my variants for the printer. The printer supports 3 materials via a material loader similar to the Prusa Research MMU2.0. So I have 3 materials which are loaded and unloaded into a single tool head. This tool head also has removable tool cartridges similar to the Print Cores on the Ultimaker 3. I have 3 extruders set up and machine variants for all of my different tool cartridges. The issue I'm having is the tool cartridge (variant) needs to be selected manually for each extruder. I'm trying to make it so that when the user selects a tool cartridge (variant) from the drop-down, that tool cartridge is applied to all 3 extruders. As far as I am aware there are no other printers with this type of multi-material setup included in Cura, so I'm not sure if this is even possible to do without modifying the Cura source code. Thank you in advance for any ideas or thought you might have.

I have been having the same issue.
