Hello! Im having problem with mesh probing. it starts all good, but when the probing progress, it starts to get closer and closer to bed. it stops when the probe already touch the bed and then " G29
Error: G29: Probe already triggered before probing move started"

; Z probe
M558 P8 C"^1.io0.in" H10 F1000 T2000
G31 P100 X0 Y0 Z0 ; Set Z probe trigger value, offset and trigger height
M557 X0:368 Y0:275 S20 ; Define mesh grid

There is picture with "allgood" heightmap, so bed is not warped or that bad. I somehow managed to get that proper map, but nowadays its like impossible to get good map.

Hello! Im having a problem where the next tool makes a blob where the previous tool was.

There is two pictures attached where you can see the issue.

There is
"G1 R2 X0 Y0 Z2 F5000
G1 R2 Z0 F5000"

in the toolchange file, otherwise it prints midair. Is there any solution to make tool change work the way that next extruder doesnt move to the previous extruded location?

Yes with SBC.
And yes, that putty command helps. Just used it first time.

Im having the same issue with all the toolchangers that i run. its very frustrating to stop with emergency button and home all the things etc etc..

Is there any noob friendly guide to get it running...?

Sorry for the delayed answer. And thanks ALOT T3P3Tony, it was the beta firmware that caused the issues. Flashed back 3.1.1 and everything works like it should. Amazing board you have made, i have to say!!

Hello everybody!

I have custom made Tool changer, specs here:

Duet 3 + SBC 24v psu
3 channel expansion board, 32v psu.
X & Y motors are 0.9 degree, from e3d. (EXP)
All the rest stuff is from 24v psu.

I have tried everything, acc/jerk/speed/current, microstepping, different slicers, different fws to main and expansion board (from 3.1.1 to 3.2.0b3), different sd card. Nothing removes that problem i have.

I tried to print vase mode, but there is some jerky movements in x&y direction, head makes some kind of noise and there will be blob in that spot. All across the print.. All the straight lines goes like good, but if there is even hint of a curve, there will be blobs from head movement.

I tried to google yesterday and found that too low jerk in Z would cause this, but no, nothing is changing.

What the hell i need to do?
