@Phaedrux That is perfect, I will try to use that!

Im pretty sure non of the corners is dropped - But even if one corner is lower, shouldent the whole system stay "parallel"?

Im wondering if the M561 in my HomeZ.g have anything with the offset to do?

I don't believe so.

Level is the average of the 3 points that you are probing.

Flatness is what mesh bed leveling is trying to improve.

If your motion system is not parallel to the level plane, then nothing you can do to fix it. Imagine if you have sag in your gantry, you will have a hollow that the controller will try to fox by filling it in wich makes the problem worse.

Not knowing your machine or machanics, I am imagining rods with holders, try loosening and then retightneing the rod holders, or if you can, loosen and them shim them 'down' with a shim of known thickness just to see what the effect is. Even the thickness of a piece of paper will show you clear results.

@achrn Just tested, it seems so! 🙂 thanks for the help everyone

@BoA Thanks!

Glad you figured it out. Stall detection tuning can be tricky.

@dc42 said in incompatible firmware v on duet3?:

Your best options are to upgrade the main firmware using Bossa, or to run the Duet in standalone mode with a USB connection and install the latest firmware from the SD card. Upgrading to 3.0 first isn't essential on the Duet 3.

What would you reccomend to upgrade to then?

3.1.1 to bring it into line with the version of DSF on your Pi.

@martin1454 No worries - glad it's working for you.

@aidar said in Thermostatic mode? Did I misunderstand something?:

I belive your H parameter in M106 command should be H4:7, not H4:H7

Bingo! We have a winner - Thanks!

I think this is the same issue as reported here: https://github.com/dc42/PanelDueFirmware/issues/39

nikscha created this issue in dc42/PanelDueFirmware closed wrong layout when using only heater 2 #39

Added to the wish list!

Finally to the point where im satisfied.

Biggeste change was changing to BL touch - After I got my hands on an thermal/IR camera, I could see that the bed was like a mirror for the camera, so that's why the IR probe didn't work good enough

So I tried the suggestions: first an Inside-out with increased speed:

then one with outside in with increased speed

at last, outside in with Z-hop off

Looks the same to me.

@dc42 Yes I'm aware of the Van de Graff issues with belts - can cause all sorts of problems with model helicopters I believe because the tail rotor is often driven by a continuous belt and the resultant static plays havoc with the receiver. Also anti-static belts are often used in conveyor systems.

But I wonder if it's an issue with printers because generally the belts constantly change direction back and forth rather than always rotate in the same direction. It's an awfully long time since since schoolboy physics but if one reverses the direction of a Van de Graff generator, doesn't that reverse the polarity of the charge?

@dc42

it fixed the issue with RC4

@dc42
Right now it is a little bit blank - it is the magnetic part of one of those aliexpress magnetic print surface - Will try with the print surface on when i get back (the Matt print surface you print on the magnetic sheet)
