General Mach Discussion / Re: Mach3 on a laser cutter...

« on: September 19, 2018, 10:36:57 AM »

I should perhaps mention that engraved items, such as this tree image (330mm x 280mm) can easily be laser reproduced by either Mach3 or Mach4 without generating (or using) any Gcode at all – they are produced directly by the motion controller which scans the specified .jpg image then outputs axis movement together with a PWM signal (to control laser power) relating to the relevant pixel value from the image. It may sound complicated but it is simple enough.

Try doing one on granite 300 mm square.

Why ??

I think Hood is the expert here but if it's any help the only Dolphin pp that I have seen is attached.

You may also like to check that you have your Steps per Unit set correctly.

This can easily be done by using the Axis Calibration feature (Settings page) – choose a dimension of 10” or so and if the axis moves the correct amount then your Steps per Unit are set correctly.

Engraving on a laser means cycling the beam (dot) on and off very rapidly and sometimes changing the power while moving the X and Y.  Mach3 I am sure is not anywhere close to fast enough. You can do a solid line engraving, or cutting without issue I am sure.  But in this regard the Chinese DSP controller is the way to go, along with the software for that controller.

I have to disagree.
Whilst the DSP controller may be superior to Mach when it comes to laser control Mach3 can, for example, perform laser engraving operations with great precision. This laser produced lithophane is just 50mm square.

OK got it loaded and working.  But the Homing does not work right and some of the pull down windows like Motor Tuning do not work.  So it came from a school... oh well it look nicd on to something else.

Problem resolved. This thread refers; http://www.machsupport.com/forum/index.php/topic,38340.msg260054.html#msg260054

Post Processors / Re: Vectric post processor for Mach 4 laser operation.

Hi,

Has mach4 got to the point where you can control a laser without the delay turning the last on and off?  I've never got Mach3 to work without the long delays...

Yes.
For Mach3 the commands are M11Px / M10Px and for Mach4 they are M62Px / M63Px (x being the Output# being switched). These commands switch the laser at the instant of axis movement so there is no delay.
