He has hundreds of toys around the house and workshop but every now and then one of the toys has to suffer his wrath. This monkey was the latest victum.
I don't know just what goes on in his mind but I just have to love him.

(the more people I meet the more I love my dog).

Hi Mike,

From your earlier photo it appears that you are using the ESS Port3.
Ideally you should be using Port1 (which has the standard LPT parallel port pinout) because Port3 has bi-directional pins 2 - 9 and this may be causing your problem.

Yes, I think it can (with some reservations).

What exactly do you wish to use the Cmd line for ??

I think Fusco96 is made of tuff stuff but you were a bit hard on him Mike.

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

« on: September 21, 2018, 01:59:15 AM »

Hi   Tweakie,
 I now have my laser “cutting” very welll.    I was not aware that Mach3   Could be used for engraving.  So I am very interested in your comment, “ 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”.

 Could you point me to where I can learn more about this  process ?
Thank you,
Chuck

Hi Chuck,

The attached copy draft document details the Mach4 laser setup when using the Warp9 ESS motion controller. You will note that a small Gcode file is used to set the laser origin and define the parameters but no Gcode is used to raster the image.

Check out the laser thread for details of using Mach3 but be warned it may be a long read. http://www.machsupport.com/forum/index.php/topic,12444.0.html

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.

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.
