Mach4 General Discussion / Laser.

« on: November 02, 2018, 09:15:31 AM »

Has anyone else tried raster laser engraving using the ESS ?

If so could you please post some pictures of your results.

Perhaps I am missing something but so far, this is the best I have been able to achieve using ESS build 227 and Mach4 build 3882.

If you go into your Mach3 folder then open (run) Mach3.exe that should then enable you to create a new profile, shortcut, etc.

I had been hoping that other Mach4 users with lasers and an ESS may have tried out the laser raster image reproduction but overall there does not seem to be much interest.

Considerable improvements have now been made with the latest ESS plugin Build 227 and Mach4 Build 3882 but the plugin is still lacking a GUI and key runtime features such as vertical step-over adjustment and image scaling.
 
Currently the vertical step-over seems to be set at one pixel, making the scan lines clearly visible and there is a definite issue with horizontal registration although this can possibly be improved by gating the laser PWM and adjusting the gate timings – something I have yet to try.

So far, this is the best I have been able to achieve – it can only get better

Following the suggestion by Rich, if you add a new screen button then on the button press the following button code will half the value shown in the X axis DRO half it and then write the new value back to the X axis DRO.

Tw=GetOEMDRO(800)
Call SetOEMDRO(800,Tw/2)

How do you know that you are only jogging at a velocity of 6 ?

(If you are looking at the FRO and Feedrate DRO's on the main screen then they show 6.00 until such time as a Feedrate is set - this does not mean that you are jogging at 6.00).

Unfortunately, this is an issue we are seeing more and more often here on the forum – The cheap Chinese motion controller’s work but they do not fully support all the Mach3 / Mach4 functions so there will always be problems with these products.
Best advice :-  always buy a product which has the manufacturer’s full support and backup – you may pay more initially but you only need to buy once (many members have said this here on the forum “buy cheap, buy twice”).

Assuming I have the correct .xml...

As ZASto has said your accelerations are too high.

I think you need to make many changes to your setup but just make one at a time, saving the change, restarting Mach then checking the result.

I suggest...

1) Set your X an Y axis Velocity to 2000 and Acceleration to 200.
2) Z acceleration to 90

You have a conflict of Pins where you have Enable1 set as Port 1 Pin 14 and also X Axis Direction Pin as Port 1 Pin 14 - this needs correcting.
You have M3 set for Output#6 which is not enabled or set to any Port or Pin.

There are many other things that need attention but just try those to start with.
