VC3.1 Enclosed 400 Back Corner Peak
Working through commissioning my VC3.1. I'm seeing a peak in the back left corner. Not sure if this range is perfectly okay, or if it's something I should work to bring down. I want to get good results, but not looking to potentially make 'good enough' worse.

I should add this is all at room temp, as the commissioning guide seems to want me to wait to install the heater until this is done.

That's not a peak... That plot is telling you that you're frame has some twist in it going front to back... The front is twisted a bit clockwise with respect to the back.... .230 is great for a 400, I'd leave it until after a few heat cycles... Then you can address the twist if you like
After some adjusting, my A, B, and D points are all within .102 of each other, but the overall range is .437. Not sure what I will gain by adjusting the front right down to bring up the back. The only thing I can think to do is adjust the back right (point C), but I know this is not advised
its easy to do because the motor plates hold it together
wasn't your previous mesh 0.2
your adjustment likely made it a bit worse?
make sure to adjust correct corners..
and run a 3 point calibration between bed meshes and adjustment
I ran into this issue myself. For me, the fix was making sure the back/center 3030 was straight/centered, and that the linear rail was straight on the extrusion. It's a total pain to adjust, cause if it's tight on the electronics panel, it can be fiddily to move and get aligned; It has to be well squared in x, and z. And the Z1 rear motor bracket can be part of the issue too, and to adjust that, you have to drop the Z1 motor 😩
I know it's in the "you should fuss with the front" range, but every adjustment in the front put something else out of line. Straightening the back center rod was the only thing that helped me get the mesh to behave.
Gonna try this!
GL! I'm now in the <0.15mm total variance range, and the last bit is totally fixable but not sure it's fully worth messing anything up :p
