Brains Development / Detecting Fwd and reverse of Axis
« on: December 12, 2009, 12:32:26 AM »
Hi, I'm trying to detect when my A axis if moving forward or reverse. when moving forward it will actuate a solenoid valve and in reverse it will actuate a different valve and only when it is moving.

I'm new to brains but can someone help me with this? I don't see a dro for direction in the variable list.

Thanks,
  David P

General Mach Discussion / G28 Too Fast
« on: December 03, 2009, 07:17:51 PM »
Hi there. I'm trying to home my gantry type cnc with G28 and it works but it travels at rapid speed. I'd like to go at rapid speed to about 1 inch from the homing switches and then gently trigger them. Oh I'm running the G code from a script so if it's not possible to configure mach3 to do it already then maybe it can be done with a script loop. Of course I'm thinking there must be a way to configure mach3 to do it but I just can't seem to figure it out.

if I run "G28 X1" it will rapid to X1 then rapid to trigger the home. if I put a 1.0 in the homing config box for g28 it will just go to X1 and not trigger the home switch.

Thanks for any help, Dave.
