General Mach Discussion / Re: Losing Y position erratically

Just a shot in the dark but I would be inclined to look at the stepper motor controller and make sure it has enough circulated air cooling. Perhaps fit another PAPST type fan ??

Excellent work with the laser Art - that really looks the business 

I am expecting to see pictures of "great works of art" to follow

Mach4 General Discussion / Re: Making MACROS turn on OUTPUTs faster by inlining your code!!

So it means you can inline wxLua code into your G code script?

Hi FocusPaul,

No, you can't do that.

In Macro's, if they are written with the fewest number of statements (careful programming) it will reduce the number of function calls and speed up their execution time.

(In practice, as we have discovered, the Mcode call, assuming it is on a separate line, in the Gcode program is actually executed some 50 milliseconds before the CNC machine has completed the preceding line of Gcode - this has been found too early for lasers (although suitable execution time delay can be added) but for many Mcodes and indeed spindle speed changes (Scode) operating early reduces overall machine run time and makes Mach4 faster).

Hi Derrick,

Try changing your Mach configuration so pin 7 is active low (inverted).

  Im facinated that you get 10ms early on an MCode.. thats pretty early..

Just a heads up - after more tests and  assuming the wx.MicroSleep timing is accurate the Mcode is taking effect some 50mS before the completion of the preceding line of Gcode (5 x the figure I had first thought).

Hi Scott,

That seems to do the trick 

The wxMicroSleep units are uS (not mS) and it took a delay of 50000uS to resolve the issue completely
