5.2 volts should be well within spec of the board, but david should know more on that than I do.

@aidar
Ok i think i get it now, Ive been defining the mesh area by where the nozzle can go, what i should have been doing is using the probes location.
It makes sense now how it works, just had it in my head that the dimensions were all driven from the nozzle, the firmware would take care of the offset for the mesh probing area.

it only showed those messages when i had my probe offset backwards.

It cant physically get there, the print head is moving Y positive, im expecting it to stay at Y-30 so it can probe the furthest forward it can. so it moving Y positive at the start of the probing its missing a part of the build plate.

you're correct I'm using a right hand coordinates. It doesnt stay at Y-30 when probing the front edge of the bed. when it probes g29 its moving y 24 mm. I must be missing something

My corexy is running
duet wifi 1.02 harware
firmware 2.02
wifi server 1.22
dwc 2.05

I cant figure out whats going on causing my mesh grind to not probe where i have it set M557 X10:345 Y-30:290 S45 It starts probing X10 Y-6.
Y-30 is 30mm from the front of the bed and at its maximum physical travel, the bltouch is 66mm in the positive direction.
here's my config and homing fileshomez.g homey.g homex.g homeall.g config.g
any help would be greatly appreciated , i have been stuck on this for a few days now

What would you suggest as a safer way of setting x and y?

what am i doing twice? i dont see what you mean.
I'll update it once this little problem is fixed.

I noticed that I was missing M574 Z1 S1 That could be my issue, ill give it a go tomorrow. Kinda doubt that's that problem, but it's something.

That's true, it is commented out because i used to have a piezo installed. I don't have it on the printer anymore so I'm just using a end stop right now.

Its been a years since i've had the printer running, just got it going again today. It had this issue when I took a break from it.
The printer is custom built core xy running duet fw 2.0 and dwc 1.21.1

I looked through all the settings over and over, couldn't find anything out of the ordinary.
So when i home all with G28 from dwc it all does exactly as its expected to goes through homing x and y with sensorless homing, then jogging the head over to the front right corner to home z near the z adjust screw.
after its all done. Dwc reads X320Y0Z4.15 Its saying z is 4.15mm above the bed while its physically touching the build plate.homeall.g config-override.g config.g bed.g

Any help would be greatly appreciated

would being able to print multiple gcode files work somehow ? then you could send a command to ignore that file.
