Which emulation to use with PE Slic3r

Captain_sq

I use the 2.3.3 Prusa slic3r together with a Duet Wifi (2.05.1). If I choose the FW emulation "Marlin" both in PE Slic3r and in the Duet config.g I get strange behaviour; motors moving extremely slow. The only working combination of these settings - were it behaves like expected - seems to be RepRapFirmware in PE Slic3r and Merlin in the Duet config. Like this :

M555 P2 		; Set firmware compatibility to look like Marlin

Is there an explanation for this?

Best regards /Thom

if you use acceleration control with PrusaSlicer it sets the values assuming mm/sec; RRF expects mm/min ..... so disable acceleration control and you should be fine. Or use the fork by @bot

@oliof Thank you for the mention.

I'm going to upload a new release shortly with some Prusa-side bug fixes, and a few colour clean-ups. I'll post the link here when I do, or find my thread on the forum.

oliof, are you using -n8 edition? How do you like the colours? are there any changes you would think of, or problems you have encountered?

As for the topic at hand -- stock PrusaSlicer isn't too bad with RepRapFirmware. It's likely as oliof suggested, the acceleration control or other speed related setting mm/sec mm/min mismatch.

Cheers!

This is used for USB response acknowledgement format and nothing more.

The slicer should be set to reprapfirmware gcode flavor.

@bot I'm using a completely different slicer in day to day.

Interesting. I use the Duet over WiFi as mentioned. Does the M555 command affect anything at all in this scenario?

No. It's often misunderstood.

Thanks for clarifying that. /T
