Cannot smash this corner any more.

I have tried: adjusting front left down, won't go any further. raising back left up. shimming the back left up just exagerated it across the entire rear edge. halp i need an adult.

So what you can do is, raise A actually. You might be reading the results wrong, C is actually very high, while D is very low. So If you raise A, you will lower C.

Watch the video, it explains everything. The bed is defined by 3 points.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
yes, i've watched that
VisualTech48
VisualTech48•10mo ago
Well then you know what I mean, if you raise A you will lower C
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
the key on the graph indicates red is higher so i was trying to raise C by lowering A
VisualTech48
VisualTech48•10mo ago
Yes its higher, but A and B will always be flat. Always.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
yes, the mesh tells me that
VisualTech48
VisualTech48•10mo ago
Yes, so if you raise A, C will will go higher, which means it will flatten out more.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
i'll try it
VisualTech48
VisualTech48•10mo ago
Do it bit by bit. As if you raisse A too much D will then be blue and fall down. So do a slight adjustment, and then home Z Then Z tilt Then do bed mesh. Do not skip these 3 steps, Home Z, Z-Tilt, Bed mesh After each adjustment. Your quite flat besides that The X gantry looks straight.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
yep, x is great
VisualTech48
VisualTech48•10mo ago
Try it and let us know the result. You should have a great bed mesh if you just fiddle with A a bit.

RoboCopsGoneMad•10mo ago
and my triangle is spot on.

VisualTech48•10mo ago
Then you are golden. Be ware of bi-metalic if you use the classic rail+aluminum extrusion for X Its a large machine.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
whats that?
VisualTech48
VisualTech48•10mo ago
So our Rail is steel, and the extrusion it is hooked to is aluminum When you heat up the bed, you might see X gantry bow.

RoboCopsGoneMad•10mo ago

You still need to raise A The thing is When you do that, and tighten it back It can go back a bit when you screw it up So you either hold it really tight, or you clamp it somehow before screwint it up. But keep at it, just a bit and you'll get there.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
i usually leave one screw in fingertight as i adjust it
VisualTech48
VisualTech48•10mo ago
Take it slowly, its a long process saddly, because you have to wait for the bed mesh. When you get it as flat as possible you can patch it up further with Kapton tape.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
nope, still getting worse. .509. same shape

Cold bed for now I hope? Show me the bed but in full Like my image is.

Then impossible, is it an enclosed one? How are you lifting that corner?
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
it is not enclosed. i have tried raising the front corner by unscrewing the corner brace, and loosening the idler mounting screws. i've tried forcing it up with my shoulder, and also striking it from below with a malet (after protecting the linear rail first)
VisualTech48
VisualTech48•10mo ago
You have to mark it somehow And then see if you are actually pushing it up. You can even push the lower bracket out if you want

RoboCopsGoneMad•10mo ago
good idea, i'll put wedge in there to move it precisely
VisualTech48
VisualTech48•10mo ago
I do suggest going with the upper bracket, but again Try it. You need to move bit by bit.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
so i tried this... when i homed, the bed ignored bltouch, and continued straight up into the head. wtf. completely snapped the front 2 lead screw bearing arms, i hope the gantry isn't bent. fml... > bltouch span sized blob stuck to nozzle after a filament load.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
need to replace the leadscrew constraint arms, hope thats not a bent gantry 😦

😦 Don't worry its a tank of machine It shouldn't be bent Just reprint those arms. The only thing you surely did is bent the x a bit. That can be fixed with a slight push downwards or you can disassble the x and then put a lot of books and weight on a flat surface, and then reasemble

So if you push it a bit in the middle it should be okey, I've had multiple bed crashes, and even my first homing was that 2 of my front arms broke.
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
thanks! new arms are printing now
RoboCopsGoneMad
RoboCopsGoneMad•10mo ago
after installing the new arms, and giving left X span 2 taps in the middle. Ieft side of X looks much improved. will try to drop right side next.
