I have a 1998 Anilam 3300mk on an HH Roberts bed mill. In the morning when I home it, sometimes the x axis will rapid to the -x hard stop. If I anticipate this and E-stop it, reboot and rehome it (2 or 3 times) it will eventually home normally and run fine all day.
Any ideas about this?

Runaway is indicative of encoder (or cable) problems. Could be either the encoder or perhaps a power supply getting weak, although the latter would probably affect all axis about the same way.

Throughly check the cable connections first.

Thank you, once again.
