Calibrating Z offset for X and U carriage for IDEX
-
Hi Adam,
I'm getting close but not there yet
just got 1 toolhead printing at the moment. next step will be to see if above instruction would actually works…

You only need a z-offset for the second head, why would you use two probes?

So you don't have to calibrate the Z offset of the second head manually. The value might need some tweaking but at least you wont have to manually re calibrate after doing any work on the printer. This becomes especially important if you're not using 2 identical toolheads (i.e. E3D V6 and Volcano)

In firmware 1.20beta1, which I am about to release, you can use G30 S-2 to probe the bed and adjust the Z offset of the current tool, instead of adjusting the Z=0 position. But if you want to do ditto printing on an IDEX printer, you need to get both nozzles at the same height anyway.

I think you can use the very same probe and assign it to different toolhead since all toolhead will be probed 1 at the time right. Maybe David can confirm

Works for me! I probably won't do any ditto printing though, but we'll see.

I'm glad it's working for you. So can you confirm that it is adjusting the tool Z offset in the correct direction?

Oh no I haven't actually tried it yet, I'm just saying that that method will work for my needs. I'm nearly finished with the design of the prototype, I'm just waiting on quotes back from a few suppliers. I just wanted to make sure I understand as much as I can so I don't waste any money on parts that need to be changed.

can you add the G30 S-2 write up of explanation how to use in the G30 section? I checked and it didn't have any S-2 there
Thanks,

Also
Is the G30 S-2 working in 1.2 firmware? I am in the process making a nozzle touch switch so I can automatically set the nozzle heights for each of my IDEX carriages.
