Homing issue on IDEX
-
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

Thanks.

@make_shake99 I'd recommend to unselect all tools at the end of a print so they get parked correctly with
T-1. In addition, addT0 P0at the beginning of homez.g and homeall.g, addingT-1at the end again for a well defined state and no tool selected<>RatRig V-Minion Fly Super5Pro RRF<> V-Core 3.1 IDEX k*****r <> RatRig V-Minion SKR 2 Marlin<>

Thank you I'll give that a shot later today.

I also noticed in your homeALL.g file in the G1 H2 command to backoff from the endstops the U value is wrong based on the U values in the G1 H1 commands.

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

did the trick thanks so much
