@mario I will be doing that soon.

@mario Got it. I will try if I couldn't find that LED ring. Thanks.

Another question i want to ask, can i use simple white LED instead of WS2812 ? i will attach a switch to turn it on and off

@mario tried ttyUSB0 but ttyACM0 worked for me, now stepper and laser is working on clicking that setting, now i have to callibrate. Thanks
