Welcome to the SeeMeCNC Community

so I did my first large print 208mm wide, and I noticed that in the z-y corner of the bed the nozzle was touching, causing my filament to jam a little and about a mm to not print on my first layer. I ran the Gcode for the calibration but it is only a 3 point cal? in matter control there is an option in printer leveling for 7 and 13 point disk,and require leveling to print. if I chose 13 point and require leveling to print will it cal correctly?

I added a #6 washer under each of the hold-down clips so I could snug them down and have an even tension on each to (hopefully) reduce the non-planar forces on the bed.

cross posting is poor form, imo.

How many times have you tried the auto calc? Maybe something went wonky the first time.

I am having the same issue on my bed, the area between the X and Z towers is higher than the other points around the bed. I have confirmed this by breaking out my calipers and checking the bed heights using that and found about a .15mm height difference depending on where along the diameter I measured. Is there a way to add more points to the auto calibration sequence to avoid using the 7 or 13 point system that mattercontrol has build into it? I love the auto cal system but using only 3 points is not giving me a nice level plane.

Just thought it might not just be a v3 thing. And I have calibrated three times. I am pretty sure it's taking it because I have no issues on the xyz, just in between them on the outer 3-4 inches

BTW I have buildtack on my glass and I set it with the mounts for the bed flipped so it looks better. With the buildtack it holds firm

"looks better" doesn't mean "correct".

In some cases, yes. In this case, no.
