I will try that. I did not realise that the M10/M11 needed to be followed by the P1 command (in this case). I had used G4 with P, then of course the P was the parameter to G4.

I had tried S********* for ON and S0 for off, and was looking at the motor tuning for speed ram

As I mentioned in an earlier posting your existing controller does not support using the M11/M10 commands.
 

This SainSmart blog mentions using the Z axis but if, like me the Z axis is used for laser focus then an imaginary axis (the A or B axis) can be used.

However, be aware that gating the signals may be necessary to enable EStop to switch the laser OFF and ensure operator safety.

Hi there,

Yes you did mention the board not supporting M10/M11 commands.

I have tried the ZDIR, and this tums in the LED on the board, but not the laser. Did you get it to work and did you have special settings
I have made a sample test, and this toggles the LED on the board, but does not turn on the laser.

By this I claim that their application note does not work.
Have you got it to work?

Hi there Tweakie,

I have been playing with the Mach3 Macros and found out why the M10 and M11 commands do not work. It's not the board, it's just because the macros M10 and M11 work on output9 and this is not set up for this board. They also do not refer to the first parameter P either.

I have written two other macros based on these, and these seem to have fixed the problem.

Do you still use this board? Then you can try them. What a labour!! Separates the men from the boys I suppose!

Sainsmart do not know MACH3 evidently, so they could not help, but I
am waiting on their reply to the ZDIR problem.

Do you still use that board, and what are you doing right now?
Do you still have that problem?
You could test my ideas

Hi Lawrence,

Sorry but I do not have the SainSmart board so cannot test your idea.
