Hi all

MY Z axis has now decided not to set itself to zero after homing, it used to up to today. Does anyone have any idea why?
Report attached.

Cheers

User offset? Check the machine coordinates

I did exactly this the other day until Swissi pointed out that I was displaying WCS G54, yet the "reset home" homing sequence sets up the MCS G53 coords. Doh!

If you switch to MCS (Alt-D), you will see machine coords are all at zero.

To zero in WCS / G54, use the "set all zero" button.

Spot on Sir! MCS was displaying all zeros, hit set all zero and it worked to reset Z to zero when rehoming. Was also having an issue where I would set Z zero on toolchange yet calling G0Z0 would not result in the correct coord, Z would be 20mm above. Software version 4.20.1 must have changed somewhere along the line and required the touchplate seeting to be negative Fixed that and all is good with my world

The beta 4.49 and upcoming 4.50 releases both show the MCS and WCS coordinates in the main screen, so that should help matters. Having said that, I was already running 4.49, so the explanation was staring me in the face....

I tried 4.49 but I can't find my licence file so it remains on Acorn Free, useless to me as I have 2 motors on X and need pairing plus my MPG wasn't able to be used either.

Racedirector,

when you write a report file on your 4.20.1 install and restore that report on 4.49 Beta, the license file will be restored too.

If you don't want to restore a report file, all you need to do is copy the file "license.dat" from your old install to the new install before you launch CNC12.

Swissi is correct. You did back up your old CNCM directory correct? Open it and look for the license.dat file point 4.49 to it there.
IF you did not back up your CNCM directory, I'm sure you have a recent report file right?
Unzip it and look for the license.dat file in there.

Well I feel silly now, forgot what the licence was named. Been while since I used Acorn and am just getting back into it. Will install 4.49 again today and try things with it. Thanks swissi & Marty, you saved me
