the controller is from these people
SHENZHENREADER TECHNOLOGY CO.,LTD
it seems powerfull enough, and the software doesn't look too bad.
It's for windows, and I use Linux .. It loaded under wine ok in the house, but wont load so far on the workshop machine. so for now I dual boot to use it.
I can see me building a bigger machine, or extending this one. It looks like I could extend the Y axis out the front without much modification. But I need to build another CNC too .. busy busy !
What do you use your laser for ?
