*NEW* 4.3.0-RC2 Firmware for Original Prusa MINI/MINI+ is out
Summary
- Improved system dialogues
- Error screen includes appendix info
- RPM range increased
- PID disabled during heater test
- Saving logs to USB suspended
- Bug fixes
Improved system dialogues
Selected system dialogues were updated to improve clarity. In this release, new screens are introduced:
- USB drive error is detected during the print
- Heating is disabled after 30 minutes of inactivity
Error screen includes appendix info
In case of a more serious system error, a red error screen is displayed informing the user about what went wrong and how to fix it. Part of this screen is now information about the status of the appendix. There are two possible scenarios:
- The system detects the Appendix, then a [A] is displayed on the screen
- The system detects a broken Appendix, then no sign is displayed.
RPM range increased
Previously, the range of the cooling fans was set based on the measured values in the tests. However, as a result, some fans were not correctly evaluated by the system. The range will be thus temporarily extended and further adjusted after another round of testing to correctly detect and evaluate the connected fans.
PID disabled during heater test
While testing the hotend and heatbed heaters, the system now temporarily disables the PID regulating feature and uses full available power. This results in a faster heat-up, effectively shortening the test duration.
Saving log to USB suspended
The previous firmware release 4.3.0-RC1 enabled advanced users to save logs (results) of the tests to a USB drive for further evaluation. As stated in the release notes, this feature was experimental and in some scenarios may have caused a BSOD screen.
Based on the feedback, this feature is now temporarily disabled until a new, more robust, the USB driver is finalized by the developers. Applying a new driver will improve the handling of the USB flash drives and increase the overall stability of the system.
Bug fixes
- Some translated Prusa Connect Local messages were displayed with a longer delay, this is now fixed (response is faster).
- The final parking position of the print head (X-coordinate) was united for the First layer calibration and a finished print.
- In some scenarios, the testers were able to invoke a “watchdog reset”, but instead of displaying the red screen, the system showed a blue BSOD screen. There was an internal issue with the procedure “calling” for incorrect GUI function. This is now fixed.
- In case of damage to the thermistor (short circuit) on the hotend or heatbed, the system could end up in an endless loop of Maxtemp error screens. This scenario is now fixed and after the first reset, the system displays an error message and waits for user interaction.

Thanks for the information!
If I understand correctly, in 4.3.0 RC2 I can no longer save the dump.bin to the USB stick? I just recently had a problem (bluescreen) with the 4.2.0 and forwarded the dump file to Prusa.

Interesting. I installed the firmware and my printer keets restarting every time I print. I will submite a github if it continues.

I upgraded mine and printed an Owl in 50% size, no problems nor restarts.

@cwbullet
That is precisely the problem. The update works for most people, but not for some. There are certainly still subtleties in the firmware to regulate. I would publish this on Github.

I think mine might be due to an overhearing power suppy.

Can you still remember? I once asked for the connector for the power supply here in the forum. I ordered this connector in the USA and have installed it on a Meanwell RSP 320W. So the mini heating bed easily manages 110 degrees C. and the voltage remains stable.

Saving crash dump to USB still works. Just tried second time and it does work, at least a file dump.bin is created.

Thanks for the information!
What is the size (kb) of the dump file?
Thanks..

So about 1248 kB. I don't know how much usage affects the size, I had printed successfully few whistles and tried to save the dump file afterwards. Based on the timestamp (1980-01-01), the buddy's calendar is way of the mark. I might have overlooked something and haven't configured it correctly. Timezone is still set correctly and the timestamp for the file was correct (didn't check how precise it was, but within an hour or so).

Thank you for your efforts! My dump.bin is also 1248 kb in size. I just wanted to be sure that it is not a null byte file.

Kinda a bummer they didn't increased heatsink cooling fan or added secret E-STEPS menu

RE: *NEW* 4.3.0-RC2 Firmware for Original Prusa MINI/MINI+ is out
Baby steps. As long as the updates are coming quite frequently, I don't mind. But then again I'm running stock Mini (with SPINDA) which performs quite good with PETG.
RE: *NEW* 4.3.0-RC2 Firmware for Original Prusa MINI/MINI+ is out
I created bug report for the wrong date on the created dump.bin file's creation/modification timestamp.

Karl,
This concerns only logging the tests. Dump is working as before. 😉

Can you please be more precise?

You do not need secret estep menu, just use a costom G (M92) code at the beginning of the print file.
As far as I know the MINI is using max hotend fan speed which I measured is arround 8800 RPM. When you run fantest with 4.3.0 RC1 with usb stick you can see in the test protocol the measured RPM speeds per fan.

@zoltan
Thanks for clarifying! That means, it remains to be seen what will happen in the near future in the further development of the USB drivers for the board, whoever may be working on it.

Were is best place to respond with RC2 issue?
I have RC2 loaded. PETG filament loaded. I do a first layer cal. form the HW setting -> sheet menu. When the it completed it continues extruding about 3cm of filament.
