Strange behavior when building a table heightmap
So, my setup
VCore 3.1 500
Manta M8P v1.0,
TMC 5160 on each motor
Toolboard EBB36 v1.2
Rapido UHF
TriangleLabs Bltouch
8mm builplate
And ive strange behaviour when i'm trying to make a Height Map
He does not seem to take into account the bltouch offset, i.e. conditionally the nozzle is in the right place, but BLTouch in the standard configuration tried to make changes outside the field.

i'll post cfg file after it ends probing

you didn't uncomment line 87
that file has the offsets defined
Furthermore, make sure 0,0 and x_max,y_max is within your build plate, by adjusting your endstop positions.

I thought I only need to uncomment it if the bltouch is connected to the board. Not to the toolboard
My bad
Thanks for the tip, now I'll check everything, otherwise I had to push it to the maximum.

Whyyyy, even on a glass
#fix-my-mesh I believe has a pinned message about fixing these types of things

Yes, this is rather a disappointment, I can hardly do anything and correct my situation, but I will now check the sheet with a straightedge.
But most importantly, now I don’t see any problems, the only Z motors make a lot of noise. I already lowered the current to 1.2A
speed up your z movements

I'm talking more about the sound while holding the motor, now the motors on holding the table are squeaking.
Use the performance configs (1.6A)
Then do:
[printer]
max_z_accel: 1000
max_z_velocity: 70
Ah, this is normal. Spreadcycle sounds like that. You can fix it at the cost of accuracy (and driver compatibility, this won't work well with fysetc drivers):
repeat for z1 and z2
user overrides as always

I just looked with a thermal imager, the Z motors on hold heat up to 65 degrees. I lowered the current to 1.2 now
65 is where you want them to be
They perform best at medium temps
Mine don't get that hot though
Are you using the official steppers?
As a rule of thumb you want to run your steppers as close to the rated current as possible for best performance, accuracy and precision. The official motors are rated at 2.5A Peak. That's around 1.768A RMS.
