huge cliff on mesh
V-Core 3.1 500 - the low X high Y corner - or back left of the printer falls off ~1/2mm. I tried adding sheets of paper underneath but the edges of the paper created sharp peaks where the paper's edge was. Not sure how to approach this?

same thing towards the rear left of my printer.
I'm thinking that the gantry is somehow "higher" at that point.
I tried z-tilt and bed mesh but this would not go away so i reckon me and you have some adjusting to do
rear right - my bad
-> loosened the front right plate and push the right extrusion an mm up
meshing, will let you know how it goes
some improvemet
the other side is now lower though..
around the same -> -0.6
adjusting front left and front right points to be higher now
this could also very well be something under my g10 plate. I made a mistake by starting tweaking too early.
no dice
looks like this is the best i'll get
0.3 improvement is no joke tho
Fix your x first.
You X is going downwards now upwards.
Pull the middle UP by hand and you will see
Don't forget to do home z, z tilt then and bed mesh.
i just changed the angle
its going in the same direction it always did
upwards at the back
see the coordinates
im now getting "!! Probe samples exceed samples_tolerance"
not sure how this fits into the equation
hmm my probe mount is broken
lmao
@✨EEIN✨ check ur probe mount
Wdym angle.
Your X is going down heavily.
In the middle
Push that up, and then fix the left and right point...
i think my gantry is level and not drifting down, since it only drops in a corner? my high y high x is fine
i have beacon
@✨EEIN✨ I'm talking to @Animatrix
I don't have a proper image of your bed to help you.
How do I push the X up in the middle?
Do I have to loosen the linear rail and tighten it from the left
Sorry, is the one in my OP not clear?
No need for the mesh to be that detailed, I only need the probe details.
What you are having @✨EEIN✨ Is that your back left corner is very high, wich means to either raise A, or lower B, or do both a bit.
D is low though, wouldn't raising A make the slope worse?
You are reading it backwards.
What blue is is that the nozzle needed to travel further than the mid point.
So in this graph it looks "low" while that means it is actually high.
Just invert the bed mesh you your brain.
Blue = Far away, Red = Close.
Well its bowing quite a lot, so either disassmble the X rail and the X extrusion, put it on a flat surface and put a lot of books on it.
Or, simply, grab the extrusion in the middle nad pull it.
Not a lot, but pull it upwards and then do Z, Z-Tilt, Bed Mesh
You can do that first, just makes sure its all tightened equally. But this looks a bit to severe for that case.
when you raise the point A, you are pushing it further from the bed 🙂
thereby increasing the gap
pushing D down would cause the gantry to go closer to the bed and similarly a lower offset
but D is where the motor sits so generally you wouldn't want to mess with it
