Output pins for Mk1 controller support only On/Off control. PWM function of output pins is not supported.
Mk1 is our first controller. It is outdated and obsolete.

We really suggest that you take a look at our latest controller, especially the Mk3/4 controller:

All three output pins are able to generate PWM signal.

I recently upgrade my cnc machine with a J Tech Photonics laser driver kit. I purchased the MK3/4 board so I could use PWM feature.
I have the driver board wired up to output #2 with PWM set at 2000Freq.
When I run the Gcode program the laser comes on but does not change. On the bottom of screen the spindle shows CW@0.

I am new to using PWM so I just want to make sure I have the software setup right?
I am using PIC Lite to generate my Gcode. I have attached the program to look at.

Thanks !

I cant seem seem to get the shading to look like some of these pictures.

Here are the setting you requested. I am having problems getting the different shades of the picture. I am using Picengrave Pro 5 to generate the gcode.

Here is a link to a pdf of what the pictures should look like.

I am also attaching the program for you to look at.

Ok, we will try to test this and we will get back with results.

Unfortunately currently I found out our laser is not ready for work.
I suggest that you try different S values(also in settings), since the laser power might not be linear and you would need to test different S values in program.

try just testing S values from MDI and see what results are made on material
