[Emc-users] [Fwd: [Fwd: Shared home and limit]]
---BeginMessage--- ---BeginMessage--- Hello.. shared home and limit is no problem in EMC2, that's the config i use the most on my machines. here is the pinout for an triac denford that i have retrofitted. This config is using one pin for each axis with two NC switches acting as limit, when homing you set home ignore limits in the .ini file and if you want to home in negative direction you set - in front of the homing speed in the .ini file. I hope this will be helpfull.

Re: [Emc-users] [Fwd: [Fwd: Shared home and limit]]
Thank you, Bjorn, I will look closely at your .ini file examples. When I say 'shared home and limit' I mean physically the same switch. I see that you address that. This will give me something to start from .
