We got our BMC 20 Max II machine working after having the memory and batteries upgraded. It worked for awhile and then went down and now it seems to work but the axis movement is off. The DROs say the machine has moved 7 inches in Y but actually it moved 14 inches and the Z axis indicates 24 inches of movement when it actually moved about 12 inches. It looks like the leadscrew mapping data has been damaged. We can get the machine to reboot using enter 999 enter but what is the sequence to reestablish the lead screw mapping default.
Thanks
