What are you going to use to as guides for the bed frame - rods or linear guides?
I have 2 linear rails on the left side vertical column to structure on X/Y direction holding, where Z is seating on 4 leadscrew motor.

Ah.. Yes... I see them now. At first all I saw where the 4 lead screws.
Thanks.

Can you use stall detection for the z probe? But I have a BLTouch in my heated chamber. I run it up to 70C and so far it’s fine.

I dont think stall detection work well with Z leadscrew...

I got all the wiring semi-done now. Need to redo X/U with drag chain to make it cleaner.
Cooling loop is using customized alum distribution block I'd from other projects, Probably oversized but it seems works. Yes it has 3 loops, one reserved for Y motor later. Haven't run the pump yet.
After lots of try&error I managed to get 4 independent Z motor running G32 auto bed calibration with "probe bar". It's working but quite hassle to use as I also need to put 50mm block during the probing.
Basically I use M291 message with input-response to control step flow. Moving XY to Z1 motor location > place probe bar + block > probe > remove probe bar + block > Z2 again > Z3 again > Z4 again. It take quite a while to finish.
I will see if using traditional gauge indicator will make G32 operation easier. Since bed is quite ridge I don't think I need to use G32 frequently.
And then... put BLTouch on X for G29 meshbed, maybe make BLTouch detachable to avoid long-term high-temp chamber exposure.
Until next time

Gauge indicator is super fast to use as Z frame leveling probe bar, then just use hand to rotate the Z motor leadscrew to make Z frame level on 4 corners.
And then, the 2 screw detachable BLtouch mount for G29 meshbed leveling.
Achieve 0.020mm mean error, HAHA!!!
Next... start the X/U calibration...
Until next time

During calibration testing I figured the temp X/U wiring is really too temp to use even with simple calibration. Solution: get it drag-chained
Until next time

Would you be able to share your config set? It may prove helpful for new users trying to setup an IDEX.

Will do once I get it cleanup a bit, it's quite a mess right now
