The Shapeoko Forum

I would suggest heading over the the Inventables forum. They are the keepers of all things new with Shapeoko 2 and X-Carve (The 2's twin)

I have included an area on my forums just for GrblGru if you would like a dedicated area for discussions.

I played around with it but I no longer own a K40 and have upgraded to a larger CO2 laser that uses a Rudia DSP controller. I am currently using LightBurn and have been very happy with it.

Make sure you have a "legitimate" FTDI chip on board. The easiest way to see that is to bring up the terminal in the Arduino IDE and see if it gives a message over and over that the board is not legit.
If the is the case, Google how to load old drivers for FTDI based Arduinos.

Check the post above for a quick edit and a better explanation of the GRBL PWM.

Or by control do you mean the higher the input frequency the greater the resolution? Yes you are correct that the resolution will be greater/finer. 255 is the S setting in GRBL. It relates to the PWM output. I should also clarify that the PWM frequency is a fixed value in GRBL. It can be changed in...

The specs for the driver says that it'll operate from 0 to 20Khz...TTL I'm assuming. The frequency is how sensitive the driver input is. More pulses, higher sensitivity. Each pulse is turning the laser on. More/longer pulses, the more the laser is on, the more power is output. You can run the drive...

Two things you get with J-Tech, the best support bar none and a power supply you cannot kill. I purchased an original 1.8 watt laser which had problems and he replaced it no questions asked. I have also done some stupid things to the power supply which would have killed any other one but his kept go...

I'd be extremely cautious about buying a cheap chinese laser if you plan to use it to make money. The CCL is a gateway into bigger and better equipment. The K40 G+ group https://plus.google.com/communities/118113483589382049502 has a lot of people who purchased the CCL, made money with it and then ...
