General Mach Discussion / Re: code for a repeat single axis driller

It will depend on HOW your driller communicates with Mach3 as to HOW you will need to go about it. Bascially what you describe is not a Gcode process but more of a PLC ( programable logic controller) process .

You are correct I was concentrating on the Y and ignored the X (;-)

That would indicate that you are loosing steps on the first move from 0,0 and coming up short. It stops at 1.7" instead of 2". Now the important Question does teh DRO should the correct values of teh first move from Y0  to Y2 ?

Change the wiring of the switch that works over to the pins of the one that does not and see if it works ok there. THAT will tell you if it is the switch causing the problem. OR possibly the break out board.

Actually in the last example the hole spacing is in Y and it starts at Y0 then spaces 2 " each step from there.  

Are you saying that teh spacing is wrong and it is not following the Gcode or is ONLY the first two positions wrong and the rest are exacly where they should be based on 0,0 because that does not make sense .  Look at teh exact location points not just the spacing. This code is abs code not incremental. So all positions should be an abs value.

What controller are you using ? LPT or other ?

I would first check your Gcode file to make sure IT is correctly coded.

Then work out from there.

Yo may want to post the Gcode you tried so others can test it.

General Mach Discussion / Re: Another strange axis movement: G37 and 4th axis

With an outside controller like ess IT controls the motions for the G31 NOT mach3. IF you are getting uncontroled multi axis moves with a G31 move then it IS a ESS plugin problem OR a firmware problem in teh ESS.  I know for a fact that teh LPT version does not do that.

General Mach Discussion / Re: Problem on Mach3 Index Input as Spindle Speed Indicator

« on: January 07, 2016, 09:19:03 PM »

Later version of Mach3 will only show true spindle speed when the  M3 or M4 is active. It will NEVER be changed . So even if you do not have spindle control you must call M3/M4 to see true spindle speed. Just turn on teh spindle control and leave it constantly on. 

There is a setting called pulley ratio in the spindle setup. THAT is where you use math to adjust the differintial between actual RPM and indicated rpm.
