Cura custom machine_start_gcode for separate material warmup
Posted
· Cura custom machine_start_gcode for separate material warmup
So OK I would like to distill this to two questions:
(1) In JSONs, can I access the material temperature settings? It seems like I cannot, I can only access a global default print_material_settings
(1B) If I can access material temperature settings in the machine instance, can I also access it in the extruder specific json?
(1C) If I add a temperature command to my extruder start gcode, does cura see that and turn off its M109 print temperature command? I understand it might not be enabled for the extruders but I can't figure out how to confirm, it seems my tests so far suggest it is not functional in extruder JSONs. I can make a post processing plugin (due to all the help on this forum:)! thanks daidhai8 and others), but I would love to edit in jsons.
(2) What is the meaning of "extruder_start_pos" and "extruder_end_pos" The value exists for X, Y, and Z, but in output files I only see the extruder ever moving to the prime position, not the extruder_start_pos. I expect the extruder_start_pos would represent something like "go here before the extruder_start_gcode" but it does not seem to represent that.
My goal is to make a "perfect" dual extruder setup for my custom reprap, so I'm trying to tune a bunch of extruder switching things. I want to do it to whatever extent I can in the existing functionality, but I will supplement anything I can't do with a post processing plugin (which would be more satisfying if I could set them to always apply, like "if using dual extrusion, turn on this post processing plugin" but I also think that is not an option.)
I hope my questions aren't too much, but I'm hopeful there's someone with knowledge about this who can swoop in because it's been a lot of trial an error messing with this so far .

In the Cura 5.8 stable release, everyone can now tune their Z seams to look better than ever. Method series users get access to new material profiles, and the base Method model now has a printer profile, meaning the whole Method series is now supported in Cura!
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
