General Mach Discussion / Re: Turn laser on and off for reference.

« on: December 31, 2019, 03:45:13 AM »

Another suggestion...

If you move on to Mach4 then your ESS will allow you to gate the ESS generated PWM and Mach4 derived M62/M63 switching signals into one output which you can then connect to the TTL input of your laser. If set-up correctly this will then enable your laser to be switched ON/OFF at any chosen PWM power setting.

My reply #3 perhaps ?

Good suggestion and it would clearly be very useful but unfortunately it is not going to happen 

(Mach3 development ended in favour of Mach4 some 6 years ago).

Well...

As far as I am aware the Warp9 ESS is the only motion controller that supports both Mach3 and Mach4 with the M11Px/M10Px/M62Px/M63Px commands as well as a laser raster engraving facility for Mach4. You would have to decide if it meets your needs both now and for the future.

I do have and use a Warp9 ESS but I am currently testing a CNC Drive UC400ETH at the moment.

I am not able to provide details or comparisons between any motion controllers (that would be a job for the experts) but from the tales of woe, here on the forum, it would be best to avoid any of the cheap Chinese stuff and stick with EU or USA manufactured products.
For laser use there are some special Gcode commands which, for speed of operation, are linked to axis movement (M11Px, M10Px for Mach3 and M62Px, M63Px for Mach4) and only a motion controller that fully supports these commands should be selected.

Hope this helps,

Hi Dantas,

Ideally, posts in this part of the forum should be made in English if you can.

The 'draw slides' make poor linear rails for CNC use. Linear rails which are purpose made for CNC use would be a much better investment in the long term.

Also, suggest some USB control boards which have been tested and proven.

Best to choose Ethernet (rather than USB) and a controller that supports Mach4 as well as Mach3. The actual make and model will depend on your machine and exactly what you want to be able to do with it.

(I currently have 5 different motion controllers and they each excel at a particular task).

Sounds like you could be loosing steps because your max. Velocity / Acceleration is set too high.

Add the line;

G01 F30

to the start of your Gcode. Does this resolve the issue ?

The 12/24V (connected to the 12/24V Power terminals) powers the opto-isolators the only voltage passed back to the Parallel Port is 5V.

You need the 12 to 24 Volt power connected to your breakout board before the limit switches will work.
