Cant get this corner down
Any suggestions, I have watched the video referenced here a lot but I cannot seem to fix this?

I played that game alot today.. What I ended up doing was in addition to the 3 corner brace screws to shift things I also took the mounting brackets to the electronics panel loose and then snugged them back after adjusting. In your case it looks as if the left rear needs to be raised a bit. Overall I played for an hour and got mine to a .23 variance.
I was told.. .5 on a 500 was anacceptable range so my .2 on a 400 was wonderful
Thanks, so even though the left rear is the highpoint, you feel it needs to be raised?
What the mesh shows is that you have counterclockwise twist in the frame when moving front to back... Twist the front counter clockwise to compensate... Run ztilt and mesh after each tweak
so twist a counter clockwise frame, further counter clockwise?
No... The rear of the frame is twisted counter clockwise with respect to the front... Or, equally, the front is twisted clockwise with respect to the rear. Thus twisting the front counter clockwise to dial out that twist
Perhaps my problem is I dont understand what "twisting counter-clockwise" means, My brain works in lengths of beams not really in twisting structures. If anyone can distill and let me know which lengths to check/shorten/lengthen, I think i'd be in better shape
Any chance you have a rubik's cube? Easy to visualize with that... Short answer is you need to raise the front right corner, or lower the front left corner... The ztilt and run another mesh
praise/hi-5 emoji, I rewatched the video and came to the same conclusion "B" needs to go up! got it down to .375 and know what i need to do, sorry for the thickness
No worries... Took me a while to get it also... The trick is to understand how ztilt plays a role after making adjustments... Good stuff! Looks like most of the rest is just gantry bow - probsbly not even worth chasing at this point
Down to .286 not aiming for perfection but curious as to common methods to fix "gantry bow," any shortcuts as I did not glean this from the mesh video?
have you started printing yet? sometimes a heat soak alleviates some of the bow... otherwise you can try playing around with torque on the bolts holding the rail to the gantry - it's really just very fine tuning at this point...
fwiw, sometimes a heat soak makes the bow worse 🙂
Oh Snap!
that's golden!
