Trouble inserting a magnet
I had two issues I'm looking for assistance with.
First, I used Prusaslicer 2.2.0 to insert a pause print (right clicked on the + sign) so I could insert a magnet into a print. The printer paused correctly, but when I clicked resume print, the print head went to the model then went back into pause. This happened over and over. I had to click resume print about 10 times (I didn't actually count), then it finally began printing. Any idea why that might occur.
Second, the process above was all for naught because there is something magnetic in the print head and as soon as the print head went over the inserted magnet, the magnet leaped to the print head and stuck to it. Anyone have any pointers on how I might be able to avoid this?
RE: Trouble inserting a magnet
Try to dimension the hole for the magnet in that size, that the magnet is a little bit bigger than the hole, so that you have to use a little bit of force to get the magnet into the hole. Or you try to use superglue to use the magnet in position.

RE: Trouble inserting a magnet
What version firmware is your printer running ?
RE: Trouble inserting a magnet
@neophyl, I'm using 3.8.1-2869
@clemens-m Thanks for the suggestions!

I suspected as such. One of the bugfixes put into firmware 3.9.x is for a loop around M601 (Pause/Resume)
Infinite Loop
G-code M601 was in specific scenarios causing an endless loop.

I did it this way - Insert in the printer settings at g-code before or after layer change:
; pause
{if layer_z==xx.xx}; set pause-z-coordinate xx.xx (z-insert-position)
M117 pause printing
M300 S1000 P500
G91
G1 Z50; pause, move print head up (check max_z)
M104 S170
M0 pause - press knob to continue (insert magnet or nut and clean nozzle)
M109 S[first_layer_temperature]
G1 Z-50; continue, move print head down
G90
M117 continue printing
{endif}
Don't forget to comment out this g-code after printing or set it to e.g. 999.
