Extruders collide when raft is enabled.

[kerembyl 0]

Hello everyone, 

 

I am working on independent extruder and configuring settings. Tool offsets, tool start and end scripts are working seamlessly. I get nice prints without raft. When i enable it, extruders collide each other and print fails. When second extruder kicks in (tool on the right side), it just does unnecessary movement along U axis and hits extruder parked on the left (1st one)

 

If i disable raft, i can even print larger models without issue. 

 

I have tried to tune printhead offsets in cura but no results.

 

Am i missing something? Looking forward to hear from you, folks.

 

Thanks.

I`m having the same Problem.

If you can post a copy of your Cura project file (.3mf, in Cura get it ready to print then go to File > Save Project), as well as the gcode file you've tried to print, then we can have a look and see if anything sticks out as wrong.

As you have found, Cura doesn't actually support IDEX printers as there is no native support for the "U" and "V" axes.

That means many things have to be configured as workarounds.

 

What do you have the "Raft Extruders" set to?  If the Raft Extruders are mixed with some of it T0 and maybe the top surface as T1 then there can be a problem that might be dependent on where the model is on the build surface.
