Pausing the print in GCode
I have been trying to pause my print at a given layer in the GCode. I've used several suggestions and have had no luck getting it to stop and restart without going into a loop.
I've tried the ColorPrint, M601/M602 and M600.
The only one I've been able to get to work (with minimal success) is the M600 but this requires a filament change. When the change is done it adds the skirt and this then makes a mess of the print.
Has anyone used a pause function with success? I would like it to pause, move the print head out of the way and resume the print by manually restarting it at the start of the desired layer.
I have the Prusa i3 MK3 and use PrusaSlicer 2.0.0.
RE: Pausing the print in GCode
Try:
M0 Waiting for click!
Drop it in the after layer change custom gcode ... of course you'll need logic to only do the stop at your choice of layer.
RE: Pausing the print in GCode
Thanks for the input. The M0 command does the pause exactly the way I want it to.
I'm now going to dig into the Marlin documentation to figure out how to move the printer head out of the way so I can have access to the print. Is there a move command as well?
I assume I can do something like this:
M0 S2 <pauses for 2 seconds>
<some sort of move command>
M0 Click to continue
From this point it should resume the print.

Very helpful and very successful! Thanks for the video's Joan and thanks for the info Tim and Vintage.

G1 X5 Y205 F3000; Move the extruder to the side and bed to the front.
You can also set up to do a relative move of the Z to avoid any risk of dragging the nozzle across the part. But it takes a few commands. This code does similar, but not using relative mode. Change the +30 to something smaller for what you are doing. 5 mm clearance is probably enough.
{if layer_z < max_print_height}G1 Z{z_offset+min(layer_z+30, max_print_height)}{endif} ; Move print head up
RE: Pausing the print in GCode
Hi there,
I am a new with 3D printing with my Ender 3D. I recently bought a second hand Ender 3 and the guy who sold me the printer told me it was possible to switch colours with the M600 code.
The software that i use: PrusaSlicer 2.2.0 based on Slic3r. When i bought the printer i also received his .ini file for prusa. He installed the software with octoprint.
Today i wanted to print a sign (Use the Force) with 2 colour layers (first= White and the second layer = black). In prusa I gave the program the assignment to stop the printing (M600). So i sliced it and i copied the file to my SD card an I ran the file.
Conclusion: The printer does not stop at the layer that it should stop ! So i looked into the Gcode with notepad++ and i found the M600 but thats it! There is bunch of codes and than M600 with no other command.
Everybody is talking about how easy it is to swap the colour and M600 ... Every sollution that i tried it has no effect. M600 is not working. The printer continues to print.
Help?
Thnx in advance
RE: Pausing the print in GCode
The question you should be asking is does your Ender 3 firmware support M600 ? The Marlin standard consists of LOTS of codes with their parameters, however it is up to individual suppliers to compile support for them into their firmware. The Prusa MK3 supports a subset, the THD firmware another and Creality another again.
If the previous owner was running the printer via Octoprint then as Octoprint spools out the commands a bit at a time as long as Octoprint supports M600 then that might be enough to pause a printer that doesnt itself support M600. I dont have a Ender 3 and my Cr10 isnt running stock Creality firmware anymore so I dont know if the Ender does or does not support it.

When i making up a drawing (like i mentioned, the Use The Force sign). I give prusaslicer the command to change the colour of the drawing (M600). I see this command in the G-code (M600) but in the G-code there is not any other info like M600 (no parking, no stay heated, no lAYERS...NOTHING!). A friend of mine is working in Cura and he made a G-code for me with the M600 rule. In that G-code I see the the Layer number, the temp and other stuf. But still, the M600 won't work.
RE: Pausing the print in GCode
Of course there’s only the m600 in the gcode, that’s what you are telling Prusa Slicer to add when you insert the colour change option.
when the printer receives the m600, the printer performs whatever it’s been programmed to do when it receives a m600, so a mk3 will use its built in defaults for the m600. If you send m600 to a different printer it will (if it supports it at all) it will do whatever it is programmed to do. If you provide extra parameters then the printer will use those you provide instead (assuming they are supported in that firmware). it’s like sending G28 on it’s own, that homes all 3 axis, if you send G28 with X then it homes only X
If you want to provide an different gcode then use the add custom gcode option and whatever you enter will be inserted instead.

Actually, to be more accurate, on Prusa printers sending a G28 on it's own will home all 3 axis and then also run a bed mesh level routine. You want "G28 W" to only run a home on all 3 axis on Prusa FFF printers. AFAIK this is a Prusa unique behaviour, and reinforces your argument. 😉

RE:
How would I command the head to lift up my 30mm a specific time, have the printer pause for 10 minutes and then continue printing again?
Thank you.
If this is the code:
{if layer_z < max_print_height}G1 Z{z_offset+min(layer_z+30, max_print_height)}{endif} ; Move print head up
how would I bring the tool down after the pause?
Is there a way to do it with a button/wheel. I have Ender 3 Pro.
