RE: Artillery x2 on PrusaSlicer
I think the problem is your E positioning type.
The Cura Gcode is has
M82, which is absolute positioning on the extruder.
The Prusa profile is using M83 , which is relative extrusion.
On a normal print this difference wont be a problem, as the firmware is instructed what mode it is in so the values in the gcode are used correctly.
However when you perform a filament change I suspect the printer firmware is reverting to Absolute positioning. As such when it exits the firmware after the change it is still in Absolute and therefore all the values for extrusion are now wrong. Firmware should really restore the type it was set to before hand when it exits its built in routine.
For example if the printer had extruded 20 mm of filament at the time of the change then with the system set for absolute the next extrusion would be an E22.5 (if it needed to extrude .5mm after the pause). Whereas for a system set to relative like the Prusa profile the extrusion command would have E .5, so I suspect the artillery is actually retracting. Its complicated by the fact that on the prusa profile if it has been set up for relative then there is probably a G92 E0 performed on each layer to reset the E count to remove accumulated errors.
One 'fix' is to redo the artillery's printer profile in PS to use Absolute extrusion like the Cura profile. This is simple if you know what you are doing.
Under Printer Settings>General>Advanced make sure Use relative E distances is Unticked.
The you will have to modify your custom gcode blocks for start/stop to change any M83 to M82. You will also need to Remove/disable the G92 E0.0 commands in the Before layer change fields in Custom gcode too.
You could try those changes and see if the pause then works correctly.
An alternative that may be simpler (but I'm not sure if it will work) would be to change the Pause Print gcode field to
M601
M83
Which should theoretically put it back into Relative extrusion after the pause. It depends on just how the firmware is processing the lines and what order its doing them in.
I'd expect the same issues to be occurring for a colour change too. If the M83 addition works for pause then it should also work for the other custom blocks too.
Anyway that's my best guess, just up to you to try it now.
RE: Artillery x2 on PrusaSlicer
That was very nice of you.
All printers in the middle of a 73 hour job.
I'll try that as soon as they finish.
Both aproaches look great.
First one even seems to go te core of the problem so it should even work with hardware pause and stop.
I'll come back to you as soon as print jobs finish with test results.
Again thanks a lot.
RE:
I would marry you right now @Neophyl. Looks like it's working!
I paused the printer on the screen and then resumed and eveything was fine.
There is only this funny thing.
It finishes the current trace (not the layer) at light speed. After that it reverts to normal for the rest of the job.
It seems to do so extruding so it doesn't seem to be a problem.
I'll do more tests on that.

I hit pause on the screen, change the filament, resume and everything goes great.
Still haven't tried the M600 and M601 with and without M83 after.
Since they are supported and resuming is working I guess the codes should simply work.
By the way, shouldn't it be M82 instead of M83? I didn't get that.
This is a huge deal for us owners of Artillery printers.
Now we can resume a printing job or change an empty roll using Prusa Slicer.
Anyhow, I'll do a couple prints and run the remaining tests with all M600-M83(on and off) variants and come back to you with Artillery X2 and Genius Pro full profile.
Thanks sincerely Neophyl.
RE: Artillery x2 on PrusaSlicer
The speed difference until the next line is the same basic problem as the extrusion. Gcode is very simple in nature. So if you do a movement such as
G1 X100 Y.5 Z0.25 F1500.0 E15 ; Draw the first line <to use one from your above list, then you are saying to move to these coordinates at this speed with the speed being set by the F1500 part.
If you then have a following line with G1 X50 Y20 then it will move to the X and Y coordinates at the same speed as was set by the previous line as you haven't set a different feed rate. It still uses F1500.
When there is a M600 or M601 (or anything similar) the firmware takes over and uses its own built in processes to accomplish the task of the 'shorthand' M600 command. It will go off and do various moves etc at whatever speeds its been programmed with. The problem fundamentally is that firmware *should* store the settings from before it goes into the pause and restore them afterwards before exiting.
As for the M83, yes it should be that if you are trying the second method, as you are telling the printer to go back to relative addressing on extrusion after exiting the pause/colour change. M83 is relative extrusion.
At the moment with the original PS profile its all set for relative so using M83 and has the relative tickbox enabled so all the E values using that.
The it goes into Pause, and somewhere in all that built in code its being internally set to M82 (absolute). Then when it exits the pause its still in M82 absolute so in theory adding the M83 once it exits pause should set it back.
Anyway I'm glad it seems to be working for you 🙂
RE: Artillery x2 on PrusaSlicer
Jaime, What did you come up with for a profile
I have two X2 printers I did the M600 firmware upgrade on one, but still has that pause/resume issue
RE: Artillery x2 on PrusaSlicer
After updating the TFT firmware and just adding an M83 code after the M600, the color change works perfectly. Thanks.
RE: Artillery x2 on PrusaSlicer
I wanted to thank you for this contribution you made, because it was very useful to me, I managed to make the X2 pause for the color change with the prusa slicer. I would love for Prusa to make a 300x300x340 MK3S++ Extended so I don't have to keep buying these devices that are not so good. But hey, prusa does its business and they know what's best for them. Without further ado, thank you very much, excellent contribution!
