While setting up a new Arco 1010 starting with power off and X &Y to hard stops right rear. I run to work piece location and setzero there. Then if I use the GoToZero pull down and select GoTo Machine Coordinates the machine makes no movement. Looking at the serial console I see that the menu issued G53 G0 Z0 G0 X0 Y0 G0 Z0 When I select this after moving the machine position it will home back to work piece zero. If I issue a G53 G0 Z0 X0 Y0 it will home to right rear corner as expected. So I guess I'm curious why the menu action seems contrary to the wording of the menu selection ... FredQ
If you do not have home switches then there is no 'go to MCS' in OpenbuildsCONTROL, only a 'go to WCS' G53 G0 Z0 ; raise Z to safe height G0 X0 Y0 ; go to current Work coordinates G0 Z0 ; go to Z Work coordinate You can make a macro to return to MCS G53 G0 Z0 G53 G0 X0 Y0
