Hello.

I'd like to see in the new firmware cooler speed in the % ( 0..........100% and not like now 0...........255)

Thank you.

I can not find the "Experimental" settings that were in 4.3.3 is there a reason or is it hidden?

Ahhhh sorry ! I thought the new one was in the "First layer calibration" menu :)

It's fine on "Calibration / Live adjust z".

Sorry for my mistake :)

Did you try menu Calibration->Live adjust z ? What do you see? can you share the display photo?

Hello !

I just built my prusa mini+ and installed the supplier firmware (4.3.4). I don't see the satin sheet (from what I understand, I would need to do a factory reset).

But I don't see the "New graphics for Live adjust Z" (which was supposed to be here from version 4.3.0). Do you think I need to do a factory reset for this one to appear too ?

Thanks a lot!

Sébastien

Updated and reset the printer with no problems.
Only scary part: after the reset, it asked for the Selftest and part of that test includes heating the nozzle to 290°C, with no way to unload the current filament. Ended up pulling the power plug, before burning the loaded filament.

@mrstoned is correct, the MINI only sets a high target temperature and then measures how the nozzle responds at "full throttle" (we need to avoid temperature PWM kicking in). The test is terminated roughly around 160°C. If the heater reached the temperature within some time frame, it is considered OK. If the temperature rose too fast or too slow, it is considered NOK.

This behaviour has been there for quite a while (at least a year or so).

However, we are making a note that the display probably shouldn't show the target temperature to avoid confusing users.

It doesn't actually heat all the way to 290 (or atleast my update/reset didn't do that).

good question.........I checked with Prusa Tech chat (Marek V.), who was nice enough to try a factory reset on their MINI real-time (great service!), and unfortunately it appears that the statistics would be lost doing a factory reset. I'd kind of like to keep my statistics, so I guess I'll skip the factory reset and just use CUSTOM1 for my Satin sheet......... Doing a factory reset would also lose the Live Z/Z values for the existing sheet profiles. Too bad these side effects can't be avoided..................

from the 4.3.4 FW notes:

Satin sheet profiles added

In case the MINI or MINI+ are used with multiple types of steel print sheets, it is recommended to use the feature “Print sheet profiles”, which enables the user to store individual values of “Live adjust Z” for each steel sheet.

The factory list previously included profiles for Smooth and Textured sheets. This release extends this list with profiles for Satin sheets. However, please note that this is just about the names of the profiles. The factory settings for each profile are the same regardless of the name. The profiles Custom1 and Custom2 will be renamed Satin1 and Satin2.

In order to rename the profiles, a factory reset must be performed. Before this operation is performed, it is recommended to write down the current “Live adjust Z” value and use it later during recalibration.
