Thank you both for your efforts and time, i DID find my mistake after all. You know, sometimes my brain is so crippled that i cannot see clearly. Somehow i added the same offsets to Tool 0 script. All is good now..

it was reported and fixed

Different issue. Tested on current RRF configuration tool 2.1.4, it puts in:

G90 ; absolute positioning G1 H2 X15 Y15 F6000 ; go to first bed probe point and home Z G30 ; home Z by probing the bed

Reported here: https://github.com/chrishamm/configtool/issues/19

Hello David, sorry for the late reply. The V1.03 is actually fine, it was the effector that somehow failed, i switched with a new one and all is fine. Only trouble i have with this one (or any for that matter), is that i cannot successfully set up the resurrect function...

On the V1.04 now, i dont see any burned chips, but I cant be sure. I tried everything in the wiki but no luck. I guess i should send it back to you for checking and repairing it..

@mpoly, it sounds to me that either your power supply output voltage is too close to the 22.5V threshold you have set in your M911 command; or you have a bad connection between the PSU and the Duet; or the 250W power supply rating is marginal for your machine. So here are some thing to check:

Temporarily reduce the power fail threshold (S parameter) to a lower value, e.g. 20V (S20 instead of S22.5). Then run a CNC job. Then run M122 and see what minimum and maximum recorded voltages it reports. Note, running M122 resets the minimum/maximum recorded voltages after reporting them, so only the first M122 report after running a job gives useful values.

Check that the VIN terminal block screws on the Duet are tight.

Are you powering anything from the 250W PSU apart from the Duet (and hence the stepper motors)? As a CNC machine doesn't have heaters, I think a 250W PSU should be adequate unless you are powering additional devices from it, such as a spindle motor.
