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 .

Are you a startup using 3D printing? Perhaps you should continue reading...
Together with BASF we are launching the Forward AM Innovation Award - the very first global contest for startups developing new applications with 3D printing!
Why apply?
The winning startup will receive €100,000 in goods and services*, along with coaching and marketing exposure from top-notch leaders in the industry.
Who can apply?
Your startup creates products using Additive Manufacturing, is less than 5 years old, and has less than 50 employees. We are looking for 3D printing applications with a strong focus on innovation, sustainability and scalability.
Dental aligners, shoes, tools, automotive parts, music instruments, industrial tooling and molding, medical implants, sports equipment, toys, architecture, fashion, construction... all are welcome to join!
Do you have an innovative, sustainable and scalable idea that leverages the unique possibilities of 3D printing? Then it is time to apply!
More information can be found here.
Applications close on March 28th, 2021
* What does "in goods and services" mean?
The winner will be able to pick any item from the overall product and service portfolio of the sponsors, e.g. printers, materials, consulting, software... Choose whatever you need to accelerate your startup.
Often getting started is the most difficult part of any process. A good start sets you up for success and saves you time and energy that could be spent elsewhere. That is why we have a onboarding course ready for
Ultimaker S5 Pro Bundle, Ultimaker S5, Ultimaker S3 Ultimaker 2+ Connect.
They're ready for you on the Ultimaker Academy platform. All you need to do to gain access is to register your product to gain free access.
Ready? Register your product here in just 60 seconds.
