@fcwilt said in And here we go again G29 Bed Mesh leveling going bonkers:

So Z2 is at X-60.5 and Z4 is at X360.5?
I had a friend who was having a similar problem and it turned out that he had the Z motors wired the opposite of what he thought and thus each leveling pass made it worse.
It wouldn't hurt to double check your printer.
In your M92 command you have Z1600.00:1600. While I doubt this is a problem the correct syntax would just be Z1600 or Z1600.00 if you prefer the trailing zeros.
And just to make sure, Z1600 would be correct for 2mm (lead and pitch) lead screws - is that what you are using?

Yes all of it is correct an i corrected the M92.
Motors are correcly connected and i tried to plug them the other way around, that made things way worse as you and @Nurgelrot described.
But these things did sadly not help.

What did the trick was to reduce the Probingspeeds to this:

M558 P1 R0.5 C"zprobe.in" H5 F600 T50000                                       ; set Z probe type to effector and the dive height + speeds

and to give the steppers a little bit more juice upped the game hier from 1400 to 1600 and upped the drivespeed of the steppers to a max rate of 1600.

Now i finaly have a Mesh Level wich i can trust:

Thanks for all your thougts an the help.
Will mark this thread as solved.

Ok for the next time i will do that.
Should be mentioned in the Wiki.

Hi, had the same question at some point where i was using swithes instead of the stallguard homing.

My approach was to use some kind of IR-Probe style switches witch would spit out an analog signal and would slow down the axis like in the z-Probing movement with davids IR-Probe but only for X and Y.

Dont know i that is possible though.

Besides the cycloidal geard extruder, the filament path looks like pain in the arse to fiddle the filament in .
An as an mechanical engineer i am not a huge fan of unsupported beams of aluminum hanging in mid air trying to hold up the linear rails and hole printheadassebly.
But ohterwise i am curios to see what else prusa will bring to the table with this printer. Looks like an interesting design of the docking for the tools.
