I use Prusa Slicer on a Tronxy XY-2 pro. I believe its firmware is of type RepRap, as I had to input it into the Prusa Slicer initialization questions, but I'm not sure.

I tried three ways, none of them work.
1) `M117 L0 E0` from https://www.youtube.com/watch?v=wOpZTGfFv1I and nothing happens, it chains the G1 movement steps flawlessly.
2) `M600` nothing happens neither. From https://www.youtube.com/watch?v=oF1SdIR-Kow
3) `G1 X10.000 Y200.000 E0
M105` and nozzle does a micro stab into the plastic, get stuck, struggle for a few seconds, then continue the printing. Also from https://www.youtube.com/watch?v=oF1SdIR-Kow

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 cut in the process.

Here is the G-code of the file I tryna print https://gofile.io/d/OiM8dz . You guys can visualize it at least with the slicer Simplify3D but it's not useful to this problem I guess. Pause has to happen before drawing the 50th layer, which corresponds to altitude Z10.15mm on my piece.

What instructions should I put instead please?

Does it work with your machines ? It's a tiny test piece about 15x15x15mm
