CNC

Hi,

Suddenly my spindel motor stopped working. If i turn the knob the green led D10 (that should light up), lights very short than red led D9 turns on. What could this be ? Thanks ! (see yellow arrows on attached picture of PCB)

Hello
Educator who has an ICONIC --- sorry to say comes without any actual personal help. Looking for a simplistic already to go project to get my feet wet and take away the anxiety. The person who was suppose to teach me moved away... FYI --The router has never been turned on !!
Thank you in advance --- I have spare wood I can use...

Hi, i build a CNC. It is made of 3030 and 2020 profiles. I have Nema 17 (5kg/cm) steppers, a ramps 1.4 board with 4899 drivers (all chinese / aliexpress). I have GBRL 0.9 loaded. I think my steppers are not functioning as they shoud. If they run i can easely make them stop running bij grabbing the rod. Voltage at the driver potmeter is about 0.7 volts. I crancked that up to about 1.3 volts, did not give the result i was hoping for (only the heatsink of the driver went realy hot). Is the fact that i can easely stop the stepper normal ? or can i adjust some parameters ? Now it is resulting in skipping the stepper,

thanks !
