V-Minion Mesh help

Hey guys! I just went through the usual steps of getting a nice mesh with my new Minion. As long as it was somehow related to one of the three screws, i was able to dial it slowly in. But now i actually don't know how to improve this anymore šŸ˜… I did put the Gantry in Parallel in the built process, and as far as i can see, that went okay. I used the RR PEI Sheet for these measurements, but just for a comparison also used a Prusa Mini Satin Sheet - the zero level ofc changes quite a bit, but the basic shape stays the same with both....

Anyone willing to try and tackle this one?

LUL apart from the weird grand canyon, the overall mesh is similar to what i've had every time i've probed it, be it with a Bltouch or the new inductive probe i have now I've not checked if the bed plate is measurably flat in the corner where it dips hard, so it could just be it being bent slightly...

Quick question I thought the stock gantry was supposed to bow downwards when hot. This suggests oth

quick question I thought the stock gantry was supposed to bow downwards when hot. this Heightmap suggests otherwise (performed whilst hot) am I missing something. I have already ordered a carbon gantry (I hope that helps?) had quite a few prints already get knocked off the bed so far šŸ˜¦

Need advise on how to fix this mesh

So I think I am almost there with my mesh. There is this bow upwards in the front. I redid my gantry rail, but I guess that was not the problem. Anyone have any ideas? is it a frame problem?

Bed or frame?

Does this look like a frame or a bed issue? It's a 330x330 5mm aluminium bed with a textured PEI magnetic surface. It looked fairly straight until I had to replace the heater. Measured with a SuperPINDA.

Temperature for mesh and z-offset

Since I still somehow have strange problems with my first layers being off randomly I wanted to ask at what temp the bed and z-offset should be done. So far I do both at roomtemp which seems wrong, but doing them at higher temps gives me even worse first layers. I don't do a mesh before each print but manually from time to time since the mesh takes forever at the start of every print....

Clarifications about Frame Squaring Video?

I'm looking at squaring up a V-Core 3 400mm frame that is about .65mm out of square, and I'd like to double check a few things about 3d Printers & a Whiteboard's video about squaring (https://www.youtube.com/watch?v=h7ZTq2dDTkM) It sounds like for just a tilted bed mesh, the A/B points (the X axis in the front) is generally always going to have the actual corners defining one plane (since this is where the two points of the bed triangle are?) It sounds like corners D and C are hard to adjust, so generally you're just adjusting the Bar [AD] and Bar [BC], except we do it on the A/B ends of the bar due to D and C....

V-Minion Bed Mesh question

So Iā€™m curious as to what a ā€œgood varianceā€ would be for a machine of this size. Iā€™ve been at it for a while today and the best I can get is a .091 mm variance. This is down from .455mm. Is it safe to stop here or should I keep on trying to improve it?
