General Mach Discussion / Is it possible to auto square the Y axis?

« on: November 01, 2017, 10:26:50 PM »

My CNC sometimes moves a slight bit when the power to the control box is switched on. Occasionally the Y axis moves and the A axis doesn't (or A moves and Y doesn't) which causes the gantry to become out of square.

Is there a way to set Mach3 to move the Y axis and the slaved A axis simultaneously onto limit switches to automatically square the Y axis gantry? I would like to have both steppers start at the same time and direction, but have one of the steppers stop when it activates a switch and the other stepper continue until it activates another switch. This should eliminate any racking that has occurred in the gantry and square it up with the table.

If this is possible and with a bit of fine tuning this would be an easy method to square up the machine. Any help will be greatly appreciated.

General Mach Discussion / Mach3 won't start my router.

« on: May 04, 2016, 09:35:27 PM »

I've been trying to get Mach3 to stop/start my router through a BOB connected through pin 17 to a SSR. I have the spindle relays activated and output 1 set to the proper port and pin.  I can get it to toggle on and off with the F5 key and with the spindle button.  When I try to run G Code command M3S20000 or M5 nothing happens. I have also tried to enter M3 and M5 in the diagnostic screen with no results.

I have read every post that I could find on the subject and am unable to find a solution.  Any help will be greatly appreciated.
