Bed leveling MK4s
today i showed closer to my MK4S with MMU and i found something i am not happy with it.
i print long parts so i need print long side on X (245mm), from left to right the Z moved high, maybe 2-3mm, that is to much in my eyes.
On MK3 i got octoprint installed on a micro Raspberry direkt connected on backside of mainboard and i have a tool to messure what differents on the 9pints of screws i got. with the screw and locknut mod i have adjust this very close.
is there a workaround to do this on the MK4S, and yes i will install this mod again if it not a part of MK4S+
RE: Bed leveling MK4s
If I understand correctly, what you're saying is that the X axis seems to be higher on one side than the other? Have you redone your Z leveling (where the printer drives the X axis all the way up until the motors stall out so that both Z axes are equal). It's the first thing I would check. I haven't seen a nylock mod for the Mk4 but then again I haven't looked for it because even on my MK3S's I never had a need for it. And 3 mm seems way too much to tackle with a nylock mod as this would tell me there's a more profound mechanical misalignment somewhere, either in the way the bed is mounted, or in the X-axis.

RE:
i think is better looking to wrote more see video. The Z movement from left to right while printing is heavy and this is no special slicing, this is the same layer.
so i will find out what the printer self is saying how much this is
RE:
ok i test something... i have install octoprint with plugin "prusa leveling guide"
after i found out i use a wrong USB-C cable (only power)
the plugin isn't work with MK4S. On plugin Setup i found some gcode
G28 W ; home all without mesh bed level M400 G80; mesh bed leveling G81 ; check mesh leveling results
gcode G81 don't work on MK4S, and yes i tested it on 6.1.20-rc1 to verify is it not only a 6.1.16 problem
ok, now i used the Terminal and let's start the Party. after G80 i got some lines that helped me.

so Printer 1 is BAD, 2nd can be better.
is there a Plugin that is working with Octoprint or with Prusa.Connect or Prusa.Link or somthing else to manual adjust the printing bed better?
RE: Bed leveling MK4s
i found somthing, not the best but to check ...
this is not looking good, 1.397 mm
gcode G81 don't work on MK4S, and yes i tested it on 6.1.20-rc1 to verify is it not only a 6.1.16 problemok, now i used the Terminal and let's start the Party. after G80 i got some lines that helped me.
i can't edit this anymore, i make a mistake, should be called 6.1.6 and 6.2.0
