Forum suggestions and report forum problems. / Re: PWM for laser control issues

« on: November 19, 2008, 08:35:11 AM »

Hi, I now have a solution, thanks to Art's patience and wisdom!
Command M11P1 switches output 1 on at the next axis pin transition; M10P1 switches it off at the next transition (you must output something to an axis immediately after this command for it to work - I use z-axis commands to do this, as I do not have a z-axis).

Works beautifully - thanks again, Art!    

Dear Iggy,
your idea is interesting but those two commands, control two states (on and off). If we are to implement 3 states (off, engrave and cut) for laser, how can those commands work? Commands M10 and M11 do not exist by default.  What kind of macro did you create?

It may be late, but it is better than nothing.... Thanks for your advice.

G-Code, CAD, and CAM discussions / In program Motor reversal

Hi everyone,

I'm looking for a way to reverse an axis while a program is running (by a g-command or macro). Any ideas?

General Mach Discussion / Tangential Control

« on: April 12, 2006, 09:25:33 AM »

Having read the Mach2/3 manuals, I've tried to test how Tangential control works. I actually need to cut a square surface with a blade on axis A, controlled by a stepper.

If i understood well, I'm supposed to set axis A as angular and tune this motor so that in a full rev. the DRO should show 360. Also, activate the tang. control, set the angle limit above which, axis Z is lifted and the actual height that Z will be lifted.

When try to run a simple square cutting routine with G1 moves (using only X, Y and Z values), axis Z is indeed lifted in every direction change, but axis A does not turn to face the new direction, it only turns a little (around 2-3 degrees, DRO also shows the same).

What am i missing here? Please, let me know if i have omitted anything (configuration settings: state, motor tuning, logic e.t.c.) and also show me an example routine that really works.


Thank you in advance.
