Slic3r PE 1.39.2-beta

Update: there is a new version of Slic3r PE, more here https://shop.prusa3d.com/forum/hardware-firmware-and-software-help-f64/drivers-2-1-5-with-slic3r-pe-1-39-2-t17762.html

Hi,
Josef just announced latest build of Slic3r PE 1.39.2-beta, which should solve the inconsistent extrusion issue some people had. It also has updated print settings built in.

To test it out, copy it to your computer and run configuration wizard. It will not affect your regular Slic3r and it’s settings from Windows drivers.

Note, this isn't a stable version and it is recommended for testing purposes.

Download: https://github.com/prusa3d/Slic3r/releases/tag/version_1.39.2-beta

Looking forward to your feedback 😉

Re: Slic3r PE 1.39.2-beta

Hi Jakub -

You mentioned this new 1.39.2 beta has new settings built in. When I first installed it, it had travel speed at 250 mm/s, infill at 200 mm/s. I then ran the Configuration Wizard to ensure I had proper values, selecting MK3 and checking the box to reset profiles from scratch. Now my speeds are back to the 170 mm/s for both travel and infill that I had before. Which is correct? Which are the latest values? Maybe settings got updated for initial installation, but the Configuration Wizard they forgot to change?

Thanks,
Austin

Hi Austin,
the 170 mm/s is correct value for MK3, just confirmed with my colleague and with GitHub.

Thank you so much for the response. Trying out Slic3r 1.39.2 beta and the new MK3 3.2.0 RC2 firmware now!

Re: Slic3r PE 1.39.2-beta

The release notes only mention it was caused by slowdown on short layers.. when this happens on every layer no matter how large the print.. so I fail to see how this addresses the issue at all.

Re: Slic3r PE 1.39.2-beta

printing a 40mm test cube now, will post a pic after, my speeds say 170mm/s as well. have you guys tested any simplify3d profiles tuned for the mk3 recently?

edit: after a vase mode 40mm cube print, i got this as a result. im running 3.2.0RC1 in my mk3.

Re: Slic3r PE 1.39.2-beta

Have a look at the release notes, as far as I understand the new procedure can't really help in vase mode (the idea of slowing down infill and inner perimeters enough to be able to print the external perimeter at it's normal speed does only work if there actually are other features than external perimeters. That's not the case in vase mode)

Hi mark.w2,

Have you tried a Factory Reset (section 7.2.6 in the latest manual)? If you try this, reset "All Data". You will have to run throught the complete hardware setup routine, but this shouldn't take more than 30 minutes. This completely transformed my machine, and is now printing really well, dare I say it better than my MK2S.
Cheers,
Dave Jackson

Re: Slic3r PE 1.39.2-beta

I’ll give that a go, thanks for the suggestion

Printers are idle anyway, so nothing to lose

I can't get ColorPrint to work with this build. I'm using the layer color change feature. Rolling back to the current release allowed Color Print to work correctly again.
