I’ve been looking for info setting up the PWM speed controller with my TinyG, but not really seeing much. I have them connected, but when I switch my power supply to PWM mode, the motor runs at a very low speed even though I have not sent any commands to start the motor. I have all stock tiny G PWM settings. Any guidance would be appreciated.
I appear to have a similar problem. I’ve followed the video guide in setting up my shapeoko2 with TinyG with the PWM speed controller. The moment I power up the machine the spindle immediately starts and nothing i can do input wise turns it off. I have to set it to manual spindle control. I would like to control it via code but not sure what the issue is even though the wiring is all correct per the guides.
