Maybe I am using the wrong command to home the axis. What I was trying to do was get to the home switch a bit quicker than the "ref all", which takes a while. Is there a better way to home a single axis? Also is there a way to have the homing go faster until close to the switch and then slow down?

Phil had it right...The home switches work fine when doing a "ref all home" which goes slowly. The G28 (entered from MDI) does not appear to slow down at all before hitting the home switch and then going past to the limit switch.

I am just finishing my DIY router and am having some trouble with the homing process. I have seperate home and limit switches (which work fine). The "ref all home" works ok. but if I enter "G0 X0" it goes too fast near the home switch and overshoots. I tried setting soft limits at mn 0 and max = travel (-ve for Z) and 0.5 for the slow zone but this did not help. Can someone help?

Thanks,
Simon
