Hi All,
Thought I'd share my custom IDEX machine I finally got working. Its 500mm, 500mm, 440mm build volume. I'm using NF Zone Volcano hotends with orbiter extruders. It started out as a duet 2 wifi with expansion boards but changed it over to make use of the toolboards which made my wiring much easier and clean. There are a few things to tweak and test but over all seems pretty good so far.

Here you go
Thanks I was able to take care of the back off. Works like a champ. I kind of noticed it didn't seem to back off but with tuning out my other issues, I never looked into that.
Thanks again.
@milicig The t-1 would only need to go into your end of print g code, which is a slicer setting such as cura.
I have it posted in this thread https://forum.duet3d.com/topic/25907/homing-issue-on-idex?_=1636755743309
Just note the two comments that need adjusted in home files.

Yea likely is I've been trying to tune in my nozzle distance and haven't cleaned those up.

Here you go
Hello All,
I'm having an issue with Z homing after I print with my tool1. So I noticed when trying to calibrate dual extrusion that if tool 1 is the last tool to print the next time I home it tries to use the U carriage to probe for Z. My probe is on the X carriage tool 0. All other times it probes correctly. I'm using cura 4.11 and firmware version 3.3 my machine is a custom built idex cartesian layout.
Thanks in Advanced
@o_lampe Thanks for the feedback, I didn't think about the dust.
