General Mach Discussion / Re: Feed Hold and Stop
« on: June 07, 2010, 06:44:02 PM »
A point worth noting; using feedhold stops the program at the end of the line it's on within the main program. So if that line is M98 P5 L100, and p5 takes 5 minutes, you will have a long wait for it to actually stop.

Interesting. I may have to look into this a bit further :)

With a stepper as a spindle motor, is rigid tapping possible? It would have to be a dirty great big stepper for production milling, how big do they get?

General Mach Discussion / Re: Different use of Mach3 (dispensing)
« on: June 03, 2010, 03:45:53 PM »
I was thinking of using the pump with a stepper motor. Call it axis A,you could program in dispensing rates, suck-back, etc. You could also use parametric code to alter the flowrate along a run, ie ramp up and down.

Did you start from dead centre of the helix? It doesn't like that.

If you really don't want limit switches, disable them in the inputs config page.

best to cancel before toolchanges and reapply afterwards then - both tool diameters and lengths. ok :)

Hi,

If a manual toolchange is called (M6 T2) and G41 and G43 are already in effect, after a lead-out and lead-in move to get the spindle in position for actual toolchanging, will the new offsets be applied for the following cuts?

I know G41 and G42 use the values of the tool in the spindle (as shown on the "run" screen) if no offsets are specified in the code, but does G43 use a similar strategy or do i have to tell it which tool slot to get its length offset from? As ever, thanks in advance :)

Feature Requests / Re: G-code line limit in the demo versions
« on: May 31, 2010, 09:42:50 AM »
that's the beauty of handwritten code, it's so small. My mill is licensed but at the same time, any of my programs could run on the unlicensed version because of compact coding.

My stab-in-the-dark guess is that the line limit is there to prevent bulky CAM generated code from being translated without paying for the license ;)
