Firmware 3.2.1-FINAL for Original Prusa i3 MK3  

Re: Firmware 3.2.1 for Original Prusa i3 MK3

3.3.0-RC1 was released today.
The time remaining estimates are most welcome!

Re: Firmware 3.2.1 for Original Prusa i3 MK3

Time remaining estimate is implemented in the latest FW, but our Slic3r team has to make some extra coding to make it all work 😉

Re: Firmware 3.2.1 for Original Prusa i3 MK3

Great! I'm looking forward to it!
BTW.. you mention that you fixed some crash detections and similar. Is this in any way connected with the fact that i've had quite some failed bed levelings at the beginning of the print with version 3.2.1? Each time leveling went fine second time after i reset the printer. I think this fails might happen when printer was hot (second print)...

Re: Firmware 3.2.1 for Original Prusa i3 MK3

Not sure if there is some direct/indirect connection, I asked our FW devs 😉

Re: Firmware 3.2.1 for Original Prusa i3 MK3

Thanks!
some days ago i've read elsewhere about pinda, preheating, cooling etc... i think guys were talking exactly in the case when pinda is already hot from previous print and this can cause wrong leveling... and they tried something to wait for pinda to cool...is this now implemented in 3.3.0 or was this only a study..?

Re: Firmware 3.3.0-RC1 for Original Prusa i3 MK3

Regarding the preheating/cooling, there is a thermistor in the MK3 measuring temps and should compensate for the differences.

Re: Firmware 3.3.0-RC1 for Original Prusa i3 MK3

Marek/Jakub,
Can you please start new threads for a new firmware.

Agreed, another vote for this. It's rather confusing. Would be very helpful to separate the discussions into a new post for each significant FW release.

Thanks for the continued development work!

Guys thanks for the feedback, noted.

Re: Firmware 3.2.1-FINAL for Original Prusa i3 MK3

Someone mentioned a permission denied issue.

A complete Hack to just get over this stage is to see which device your Prusa in on (as shown in the Sli3er Firmware Flasher menu and allow everyone to read and write to it:

like:
sudo chmod o+rw /dev/ttyACM0

then revert:
sudo chmod o-rw /dev/ttyACM0

replace /dev/ttyACM0 with whichever device your linux calls it.

Running slic3r as an admin solved this problem for me. Here is what I did:
- download the appimage
- extract the appimage in the terminal. From the directory with the appimage
./Slic3rPE-1.42.0-alpha5+linux64-full-201902041815.AppImage --appimage-extract
- then you go into the /squashfs-root directory which is created
- then run "sudo ./AppRun
