Looks impressive for the money ?

Deleted post - not convinced that the laser module isn't just driven by TTL-signal from the missing PWM controller. (ignore image that I can't figure out how to remove)

I understand

Here's a question or two:-

1) Can you write software on the Arduino?, such as to test the PWM interface to the laser without the GRBL software?

2) If you have an Arduino sketch, can you Upload (compile, link and install) the software into the Arduino?


If Yes/Yes, that's your answer. If No/Yes, then I'll knock something up for you - if you're interested.
