Dc42 ir probe on the way
-
5 minutes please
-
it´s the same. left side (Ymin) so close, that there is no layer, right side (Ymax) so far away, that the layer doesn´t stick to the bed

M201 X1000.00 Y1000.00 Z1000.00 E10000.00 ; Set accelerations (mm/s^2)
Try reducing the Z acceleration from 1000 to 100. I wonder if it's trying to compensate but trying to move too quickly and not moving at all due to binding.
Does the Z axis move properly otherwise?
-
Z axis works fine.
tested with acceleration 100, same behavior -
Have you tryied manual bed leveling?

@torro One other variable we can control for is that you're using DWC 2. Just incase it's causing an issue, try reverting to the last main release 1.22.6.
I'm doubtful it's the problem since running M122 shows mesh is active.
If that doesn't work I think I would re-run the G29 fresh and print immediately afterwards to see if there was maybe just a problem with the old heightmap.

that´s already tested.

Web Interface Version: 1.22.6
same problem

i had the G29 in the start script from the slicer after homing

Manual corrections required: 0.00 turn up (0.00mm) 0.41 turn down (0.21mm) 0.10 turn up (-0.05mm) 0.61 turn down (0.31mm)
seems to work

next round
Did another G29, added G29 S1 in config.g
in DWC, mesh compensation in use.at Xmax Z0, paper is loose. babystepping offset -0.1 paper is gripped
at Xmin Z0, paper is gripped, Z+0.15 papier is loose.
in the middle of the bed, where G30 in homeall.g is done, the distance from the nozzle to the bed is fine.no compensation. should it compensate already at this time?
just to test, i added X0 Y0 Z1 to the M558 command
M558 P1 X0 Y0 Z1 H5 F120 T6000 A3
still no compensation.
did a macro with
G30 S-1
G1 Z10
G30 S-1
...... repeated 10 timesto check, if the probe is ok. i´m getting results between 0.356 and 0.363mm @Xmax and 0.325 and 0.331mm @ Xmin
-
this is from M122
Bed compensation in use: mesh
Bed probe heights: 0.000 0.000 0.000 0.000 0.000What is meant by "bed probe heights"?
-
Ignore the bed probe heights, thay are the heights of the first 5 points that you probed using G30 commands (normally in bed.g).
Do you have bed compensation taper enabled? Having it enabled and set too low can cause first layer problems.
-
it was not enabled. tried M376 H10 and have the same problem.
-
i have to print some parts, so i loaded the "old" config.g and leveld like before.
is there a way to configure the printer like it is now and i can play around with the probe?
that´s the "old" config.g before the probe came.
Endstops
M574 X1 Y1 S0 ; Set active high endstops; Z-Probe
;M558 P0 H5 F120 T6000 ; Disable Z probe but set dive height, probe speed and travel speed
;M557 X14:13 Y14:195 S20 ; Define mesh grid -
When you enable the height map (G29 S1), if you send G1 X commands to do left/right moves, can you see the bed dropping when you move the carriage to low X and rising when you move it to high X?
-
No, there is no movement.
Z0 @ Xmin pushes the nozzle in the bed, Z0 @Xmax is too far away. When i use babystepping to get the nozzle to the correct distance, i have an offset of about 0,2mm. In the middle of the bed, it's fine.
-
@Torro, did you resolve this?
