Re: [Emc-users] Force homed signal
Just command a G53 A0 after it's done homing to move to it to zero. Todd Zuercher P.

Hi Marius, Are you driving your A axis with steppers or servos? What are you using as the physical home switch? You can always fool the homing sequence at least into some extent. I wanted to use servos in open loop but that was incompatible with homing with index. So I bypassed the home switch for the final detection, and then feeded the index pulse of the servos making LCNC believe it was the home switch. May be you can implement something like that.
