OctoPrint: M601 Printhead doesn't stay in the back during the pause
Hey guys! I really hope you can help me. I print via OctoPrint. The following problem occurs: every time I set a pause in the slicer my printer makes one. But normally the printhead should stay in the upper left corner. It does for a very short time. Then it comes back to the position it later starts the print again. I don't have a clue and my "Marlin" isn't that good. What I have tried yet:
- Set up OctoPrint properly (GCODE scripts, etc.)
- googled for a lifetime
- logged a print
Thx a lot for your help and your competence!
Cheers 😉 Matthias

RE: OctoPrint: M601 Printhead doesn't stay in the back during the pause
Do your settings in OctoPrint for the Gcode scripts look like in the screenshot?
RE: OctoPrint: M601 Printhead doesn't stay in the back during the pause
Yeah... almost... but yes 😉
RE: OctoPrint: M601 Printhead doesn't stay in the back during the pause
Ah, I see the "M604" in the first line of the first text box is not visible in the screenshot, but it is there.
So the printhead of your MK4 does not stay indefinitely in pause if you have set a pause in PrusaSlicer?
I have used my MK4 with OctoPrint for embedding clear plastic sheets into prints with a pause set in PrusaSlicer for this model here. The printer waited indefinitely until I hit "resume" on the printer display, which one time was at least half an hour. I have attached my PrusaSlicer project for the cover of one of these boxes. Perhaps you could compare the project with your settings in PrusaSlicer if there is a difference?
RE: OctoPrint: M601 Printhead doesn't stay in the back during the pause
Couldn't find any differences :/ except the starting g-code. But this doesn't have to do anything with the M601....

2024-11-19 10:13:48,146 - Resuming on request of the printer...
Imho this looks like the printer issued the command to continue the print by itself. You did not press the button on the printer, right?
RE: OctoPrint: M601 Printhead doesn't stay in the back during the pause
I'm having exactly the same problem. The sequence is:
- pause happens
- printhead moves to the corner
- it immediately comes back
- printer waits to be resumed (seemingly indefinitely)
So it's not unpausing by itself, just not keeping the head away. This makes it really awkward to, say, drop something into a hole.
Also there don't seem to be any available head movement controls in the pause "Tune" menu, and obviously I don't want to move the head manually. Hm, though can I just twist the knob to change Z like you could on on the mk3?
RE: OctoPrint: M601 Printhead doesn't stay in the back during the pause
Hmm, it has been a while since I printed the box with the acrylic inserts, so I don't remember exactly where the printhead stopped during the pause. Just that I it was not in the way for me to insert the acrylic sheet into the print, which is a bit more involved than just dropping in a nut or a magnet and requires access to the whole plate surface to do it.
Perhaps I'll print another one of those boxes over the weekend and activate the serial log in OctoPrint for it to compare what happens.
RE: OctoPrint: M601 Printhead doesn't stay in the back during the pause
I checked today with a small print, inserted a pause in PrusaSlicer and watched what happened. My MK4 had the same behaviour as described by @doagl and @jfitzinge. During the pause the head moved a bit up, then to the back on the right hand side and then right back to the printed part. When I printed with that setting a few months ago the printhead was at the back end of my printed part and so it was not in the way for me then and I did not register it as a nuisance. 😉 I guess where the printhead will wait is dependent on the position of the layer seam on the part. So it could be very well in the way for other parts and one could take care in PrusaSlicer to position the layer seam somewhere on the back end of the printed part.
After the first check I experimented a bit with adding G-codes to the pause script in OctoPrint and I think I found a solution for our problem that will give us the desired behaviour. The printhead will first behave as before, as that movement (back to the R.H. side of the bed and then back to the print) seems to be the reaction of the printer to the M601 command. But if you add another command to move the printhead to the back end of the bed on the right hand side it will do that, wait there until you resume the print via OctoPrint or via the display on the printer and then return to the correct spot on the printed part and continue. Just add the line "G1 X240 Y190" below the line with M601, see screenshot. I observed that it is not important if the command "M601" is actually present in that text box. The printer behaves the same if it is there or not. I guess the presence of the command in the gcode file that is inserted by PrusaSlicer is enough and it does not matter if it is given twice (once in the gcode file and once through OctoPrint).
If you want the printer to beep, remove the ";" at the beginning of the line starting with ";M300 ...".
I have tested this on several small prints now and it worked every time. I hope this will work for you, too. 🙂

Thanks, this works for me.
