Hi John. For some reason I can’t upload pictures at the moment. There is error message when trying to upload. Anyway, I have check many stuff on this control today and I can make my own zero offset ( G54 ... G57 .. ) but only way to do it is manual. I have to calculate the distance betwin the base zero position and material. On my Base Work Offset I have X 118 / Y -14 / Z 88. I still can’t do it in the automatic way :(

hi max. there is your problem with your base work offset. x and y should be zero. if you look at your video that you took, your g54 offset that you set was approx. x216.xxx and when the machine moved it moved to x334.xxx which is 118mm more. once you set your base to x0 y0 your work offsets will move to the correct place. this base figure is where all the other offsets come from, so also beware of your z offset being 88. My z offset is set to zero aswell so all my z offsets in g54-7 are a positive figure above the bed. I hope this has helped you.

I’ll try this tomorrow and will let you know. Thanks John!

Hi John,

All problems are sorted out :) I didn't find how to reset the Base work offset but just uninstall/reinstall the software. Now all works fine with G54 ... and BWO showing zero on all axes. Thank you so much for your help! Very apreciate this! Regards, Angel
