limits on mill table

[Robin Hewitt]

Do I need to incorporate limit switches or can I limit the motions in the software ?

If you hit a limit switch you have already blown it, fairly useless.

OTOH homing switches are really useful if you are cutting with jigs.

Agreed, I've not bothered with them on mine. I always zero the existing dials before starting off, and check the travel is ok, so if the worst happens I can get it back.

If you are using servos then you definitely should have them.
