How to pause print to insert magnet

Snapmaker J1/J1s
1

I want to insert magnet to my model, so I tried in some method, but failed. Which command enables to pause printing and resume.
I tried as follows;
M601: Pause print
M600: Filament change pause
M76: Pause the print job time
G4: Dwell
when I tried with G4, printing was paused, but not resumed. From the touch panel to resume, extruder extruded filament, moved to a point but no more work. From Luban to resume, made stop working J1 and J1 stopped the work.

M600 is supported on the older Snapmaker models, so if it doesn’t work on the J1, you should probably report a bug.

If this model is a once-off and you just want it done, you can snip the filament when the print reaches about the right point and insert the magnet when the runout sensor triggers, then reload the filament and continue as usual. (I’m assuming that the J1 has a filament runout sensor and that yours is working correctly—you may want to test first.)

Thank you. I’ll report this case as a bug. Finally, I observe J1 during printing, and paused manually and put a magnet.

Hi, I’m interested in this topic.

Is there an update already?
Or did you manage to pause otherwise with gcode?

Thanks in advance

I found V2.4.7 support M600. But I haven’t tried.

I hope you’ll try it.

Thanks for the fast reply!

That sounds good.
I haven’t bought the printer yet, but asked myself if it’s possible to pause printing without problems (because I had problems like this with my current printer) and found your post.
I will try, but it may take a few weeks until I get the J1.

In Ultimaker Cura I got it to work by using the Change Filament setting at a certain level instead of the Pause Printing. The print head parks and the hand held says ready to load.

I have the J1 and do this often to insert nuts. Never had any problems. I use Prusaslicers paus function that adds the paus command m600 z100. Not sure what would happen on tall prints though

How do you get it to resume? I have a partially finished print sitting on the bed right now that I used PrusaSlicer to slice and insert M600 Z100 command. Both extruders are parked and the printer has indeed paused, but there’s no option displayed on the screen that I can see to resume the print, only to Stop.

I’ve used only M600 to do a pause in the current firmware. (Dunno about adding that Z100
 The J1 automatically saves and parks for M600.)

If I recall correctly, there was an on screen option I could get to to resume the print, but don’t recall now where it was.

May have needed to use some back button or something to find it?

I read up on the M600 command a bit. The “Z100” part is an argument to it apparently. It would theoretically cause the tool head (or the print bed as in the case of the J1) to retract 100mm as the machine paused, but I suspect the J1 may ignore arguments to this particular command.

For whatever reason, gcode that I generate with PrusaSlicer doesn’t show a Pause button next to the Stop button on the touchscreen while printing like it does when printing things sliced in Luban. I suspect this might be related to why no Resume button is shown when the print becomes paused via the M600 command. I’m not sure what to do with this information though. I ultimately stopped the print and re-sliced it without the M600 command included.

I have a BIBO 3d printer. I was able to modify the G code and put in a M 600 pause to insert a magnet.
I was able to resume using the front panel.
I am looking at purchasing the snapmaker J1 3-D printer and being able to do the same thing.
