I use the Prusa Slicer on a Tronxy XY-2 pro which I believe uses RepRap firmware. I believe it uses RepRap firmware because I had to input it into the Prusa Slicer initialization questions, but I'm not certain that it is correct.

I tried three ways, none of them work.

  1. M117 L0 E0 from Embedding a Nut into your 3D Print and nothing happens, it chains the G1 movement steps flawlessly.

  2. M600 nothing happens either. From Embedded Magnets Thanks to Flipping Normals!

  3. Using this code

     G1 X10.000 Y200.000 E0

    and the nozzle does a micro stab into the plastic, get stuck, struggles for a few seconds, then continue the printing. Also from Embedded Magnets Thanks to Flipping Normals!.

They produce no feedback at all on the printer GUI asking me somehow to resume the print. It keeps displaying real time temperature and estimated time remaining as if there was no pause in the process.

Here is the G-code of the file I trying to print test_inserting_nuts_on_the_fly.gcode. You guys can visualize it at least with the slicer Simplify3D but it's not useful to this problem I guess. The pause has to happen before drawing the 50th layer, which corresponds to Z height of 10.15 mm on my piece.

What G-code instructions should I insert? Does this type of method work with your machines? It's a tiny test piece about 15x15x15 mm

    $\begingroup$ You can also put Marlin on the board since a few weeks ago, a much, much better firmware, which will also support things like M600. $\endgroup$

  • $\begingroup$ Thanks for editing my post, and for the tronxy commands @ Mick, I'll test the go home M8029 I3 in the next hour. @towe do you have tutorial references for flashing the board ? Will it change the user GUI ? @Davo not yet, but can you tell me to which of the table firmware the tronxys belong in here please ? reprap.org/wiki/… $\endgroup$
