VC4 500 Comissioning mesh
Hey guys, I'm trying to follow the comissioning steps but my mesh looks absolutely horrible.
I've never seen a bow in this direction so I'm not quite sure what to do from here - I've tried getting the frame more square to get the corners up, but that didn't help the bow.
Additionally I've tried to reinstall the x linear rail just in case I fucked that up - but no matter what I do I get this extreme bow. If I hover on one of those points its a difference of 0.288mm.
Does anyone have a suggestion for this?

Pull the gantry upwards by hand
Your x gantry is bowing and that also makes your back corners low.. Once you get the gantry straight you will have a good mesh
Just pull in the middle with some force. If you pull too much, just push it back down. Expect some force is needed
Thanks for the tip
it definitely got better, but I'm already pulling up very hard and this is the best it gets
When you mounted the rail, did you tighten the screws evenly from one side to the other?
It's important you screw them one by one from one side to the other
Yes, i started from the left and went to the right - I can unscrew it one more time and screw them back in just in case - give me a few minutes
It's also important that you torque them evenly. Ideally with a torquewrench
What nm amount? Then I'll try that
seems to not get better with rescrewing it
Something is not right. Did you run Z tilt after adjusting?
Your gantry is still bending a lot
1Nm
yeah I always run z tilt before meshing
do you still think it's the gantry? I've turned the extrusion by 90 degrees same result
Something is wrong with your Z tilt
For me it looks like it's a bed issue tbh
That's what I held against it
