PrusaSlicer Toolchange behaviour no Z move after toolchange
Hello,
I have been using an E3D tool changer for a few years, and from the outset I chose PrusaSlicer, and it has been great! However it has stopped putting in the G1 Z## move after a tool change which means it extrudes a perimeter or sometimes infill above the part. I have examined old gcode which has this move, and new gcode which does not, I have turned on verbose and I believe the z move is missing from the 'move to print position after unknown position' section.
G1 X95.468 Y128.284 F24000 ; move to print after unknown position
This line should have a G1 Z## beneath it, but it is missing. I have tried many things, but have run out of ideas. I did try reinstalling PrusaSlicer, but no change. I would be grateful for any ideas!!!

Sounds like this issue possibly https://github.com/prusa3d/PrusaSlicer/issues/3848

Thanks for your help. Yes I think this is the same problem, I have read through issue 3848, I appear to have been lucky, as this has only affected me recently, but from reading it has been lurking for a few years. Unfortunately it doesn't appear there is an actual fix, there are some complicated work-arounds, which are probably a bit beyond me.
From desperation I downloaded SuperSlicer, and after much tweaking to get the tool-changes working (much harder than PrusaSlicer) I can confirm that SS does insert the G1 Znnn which PrusaSlicer used to insert, but now does not. It's a shame, as I really like using PrusaSlicer and have many profiles for three printers, but I can't seem to get it to work with my troolchanger anymore.
