New FW 3.1.1 RC2 b137

Hi, new FW is out 🙂

www.prusa3d.com/drivers/

- Fixed power panic routine when absolute possitioning of extruder is used
- Random resets during Wizard caused by long user response time fixed, self test and PID calibration
- Automatic Filament load during filament change
- Incomplete file check implemented
- Second serial line support implemented to allow Pi Zero W communication
- Fail stats fixed (now resetable from Factory reset)
- Fan test fixed (now possible to catch swaped fans)
- Ambient temperature sensor conversion table fixed, and it’s used now to mask out MINTEMP error when printer is in low temperature environment
- Stealth mode acceleration and maximum speeds are now limited to prevent layer shifts
- Normal mode is now force set before XYZ calibration and self test
- Crash detection menu setting during print fixed (sometimes turning it OFF/ON wasn’t working)
- Filament sensor menu item now shows another state [N/A] which means the sensor is not attached, or not available because of possible wrong connection
- File sorting in “Print from SD” implemented for up to 100 files per directory
- Wizard tiggering during first run of printer fixed
- Menu items properly masked during first layer calibration
- Debuging output to serial line removed to prevent corrupting octoprint compatibility
- Heated bed maximum temperature set to 125 °C to match component maximum

Re: New FW 3.1.1 RC2 b137

I will try that !

FYI , my MK3 just stopped during a print.

No error Message.

It was a little bit over half way through the print after 75 hours 👿

Just tried to print a Benchy in Stealth Mode. Layers shifting all over the place.

Re: New FW 3.1.1 RC2 b137

And yet it's still corrupt...are all the preorders beta testers?
I should have bought another mk2s....(with free a shipping and $100 bling a month ago)
Why are all the YouTube builds so great?!

Re: New FW 3.1.1 RC2 b137

Maybe related to this firmware, XYZ calibration does not commence, it asks whether a steel sheet is applied and to put a paper sheet underneath the nozzle then stops with failure to check axes. Previous firmware (that came with the printer, not sure about version number, think it was b122) did start the XYZ calibration and went thruugh the first 4 steps (did fail at 2nd iteration).

EDIT: Did a factory reset, increased space between PINDA and bed and now XYZ calibration did start (and finish with (only) 0.07 skew.
Y Calibration still not starting though.
