Hello! I've mounted a tall extruder on my X-carriage, and as a result my Z-range is very limited (less than 30mm, this is fine for my purposes). I'm running into a problem with using G30 in my z-homing procedure though—the Z-axis just keeps going up after it turns around when the Z-probe triggers, and crashes into the frame. I've tried limiting the Z-axis from 0-10mm just to see if this will stop the motion, but it still goes up until it hits the frame. I've also tried sending the Z-axis to Z=5 or another small value right after running G30, but again no luck. Does anyone have any ideas on why this could be happening? Is significant upwards travel a part of the G30 command, and is there any way around this? Any insights are appreciated!

@o_lampe @deckingman Thank you both!

Hello! I'm working on modifying a Prusa 3D printer to print with both thermoplastics and hydrogels, and I need to control 2 separate extruders on a single X-carriage. From what I've read, it seems like this should be possible with the Duet 3, but I'm quite new to this aspect of 3D printer design, and I was hoping some of the many more experienced people on this forum could offer some impressions as to whether this is a plausible task for the Duet 3. Thank you in advance for any insights! - Annika
