4.1.0 Firmware for Original Prusa MINI  

RE: 4.1.0 Firmware for Original Prusa MINI

as far as I am aware this concerned a short Gcode files.

@zoltan

This does not explain how a new or old file can park ok with 4.05 and fail with 4.1. I have proven this by repeating the prints.

For reference, my Mini was ordered Day One and shipped in December.

RE: 4.1.0 Firmware for Original Prusa MINI

Is the video available anywhere apart from Facebook?

RE: 4.1.0 Firmware for Original Prusa MINI

@bobcousins

I just shared it to YouTube.

@stephen-c32

Can you please share your gcode file?

RE: 4.1.0 Firmware for Original Prusa MINI

This is the gcode in the video. It prints perfectly with 4.05. The park fails like in the video with 4.1. It is repeatable.

RE: 4.1.0 Firmware for Original Prusa MINI

@zoltan

Ok, trying again to upload gcode...

Did not work. Is there an email address that works outside of this broken forum for sharing?

RE: 4.1.0 Firmware for Original Prusa MINI

Zip the GCODE file and drag it into the text editing part of the posting

RE: 4.1.0 Firmware for Original Prusa MINI

@zoltan

Maybe it works as a zip?

RE: 4.1.0 Firmware for Original Prusa MINI

G-code succesfully downloaded,  fisrt check shows you have a bit different post print code then the standard. Will check tonight on 4.0.5 and 4.1.0.

RE: 4.1.0 Firmware for Original Prusa MINI

Hello everyone!

Am I the only one who finds the new loud & silent modes really annoying? I much preferred the old "clicks", I had to revert to 4.05 because I just can't stand the new sound options.

RE: 4.1.0 Firmware for Original Prusa MINI

@stephen-c32

i have tested the end code of your G-code file which is:

; Filament-specific end gcode
G1 E-1 F2100 ; retract
G1 Z21.9 F720 ; Move print head up
G1 X178 Y180 F4200 ; park print head

both 4.0.5 and 4.1.0 did the same movement: bed to the front print head to the right

you did not use Octoprint or other serial printing?

RE: 4.1.0 Firmware for Original Prusa MINI

@zoltan

No octoprint or other serial method, this is printed from the original Prusa USB memory stick. This file and others print perfectly from 4.05 and fail every time on 4.1. My Mini was ordered on Day One. Has there been a manufacturing  change since the first batch that could be a problem? As I showed in the video, with 4.1, it parks as it should, but then continues to move after reaching the park position. It is not a gcode problem and it only happens with 4.1. It is repeatable with different files. I can make the problem go away by going back to 4.05. Is there a checksum test to confirm that my firmware file is not corrupted?

RE: 4.1.0 Firmware for Original Prusa MINI

@stephen-c32

A bit strange, but let us sort it out.

Yes the firmware is checksummed and signed. 

Can you please zip and post your 4.1. firmware pack?

I will flash it and test.

Hi Mateo,

thank you very much for your feedback, I have forwarded it to Firmware team and they are working on sound enhancements.

RE: 4.1.0 Firmware for Original Prusa MINI

@zoltan

Please find my 4.1 firmware pack attached.

RE: 4.1.0 Firmware for Original Prusa MINI

Cool  I will check it during weekend

RE: 4.1.0 Firmware for Original Prusa MINI

Has anyone noticed if you disconnect from Octoprint from the Mini.. If the hotend assembly is in the middle of the bed, the hot end moves back to its home position and grinds as its going, not sure how else to describe it..

RE: 4.1.0 Firmware for Original Prusa MINI

I have read of the challenges that some users are having with 4.1.0, which has made me cautious about installing it.    It would be nice to hear from users who are happy with the new firmware.   I'm a fairly new user running a bog standard Mini and default profiles (with minor tweaks) from Prusa Slicer.

I agree , I would like to hear this as well. I just swapped my hotend to a mosquito and now have reliable consistent prints. I would hate to have a firmware change cause problems.
