Travelspeed when using G32 & G29

koreandi

Hi there..

I am converting my Tevo LM with a DUET 2 Wifi. I struggle a bit with the travelspeed in X/Y with G32 & G29.
I already searched for some topics but couldn´t find something that helped me.

Homing works fine. I can move all my axis with high speed. G30 is working with the BLtouch just fine.
But when I use Delta Calibration (G32) and Mesh Compensation (G29) the whole axis movements are cut down to like 10%.
Both, G32 & G29, succeed and I get the data correctly. But I would like to run it with higher X/Y-speed.
Any clue what could be wrong?

Here is my config.g
config.g

Please consider.. The Z-Output might be damaged on my board, so I mapped my Z-axis to drive 4 (E1).

On Line:

M665 R157 L397.1073 B175 H515

...value 515 is a few mm shorter than my real height. If I home all and go to Z0 I am a few mm above my bed. Is this wrong?

Or is:

M208 Z0 S1

wrong?

I hope this is just a small thing to fix.

Thanks already.

I would try to adjust the H parameter so Z=0 is just touching the bed.

M665 R157 L397.1073 B175 H515

I do not believe this command applies for firmware v3.3 - remove it.

M307 H3 A-1 C-1 D-1                                                     ; reserve pin 21 for M42 or servo use

The F parameter controls the probing speed. The T parameter the travel speed. Your travel speed is slower than your probing speed.

If the BLtouch is not at the same position as the nozzle, X and Y will need correction, because otherwise mesh compensation will be at the wrong places. Please see https://duet3d.dozuki.com/Wiki/Test_and_calibrate_the_Z_probe#Section_Measuring_Probe_X_Y_Offset

Most recommendations I've seen for BLTouch set a dive speed of F100-200, F999 is a bit too fast. Travelspeed of 12000-24000 should be possible.

When you have finished a calibration succesfully, you can store the new found values with M500. That will include the correct Z-max height.
Recall the settings by adding M501 at the end of config.g

Thank a lot.

I deleted the line

M307 H3 A-1 C-1 D-1 ; reserve pin 21 for M42 or servo use

and adjusted the speed.

Now my speeds are all right.

What could be wrong if my Nozzle is too far from the Bed?
Even if I adjust my Z-Value to 0,7 it still kepps at the same distance.

G31 P45 X0 Y22 Z0.95

with a smaller Value my Z-Offset is too far from the Bed by 0,25 mm.

I dialed my Height with 520,65 as accurate as I could.

M665 R157 L397.1073 B175 H520.65

You probably have the same line in config-override which still has the old height value? Overwrite it with M500 after calibration is right

koreandi

@o_lampe
I don´t have a config-override...
Do I have to make this file manually?
What should be the content of this file?

o_lampe

@koreandi Nevermind, if you don't have it. It mainly contains the results of heater-PID tuning and of delta calibration. You can keep these lines in config.g without problems.

koreandi

@o_lampe
After overwriting my values with M500 the file was created.
It is still the same. My Nozzle ist too far from the Buildplate.

The G31 line must come later than M558, because you can't create an offset for a tool that wasn't defined yet
