Nema17 low torque

by hendrik6073

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 !

CNC programs for mac os x?

by ah1102

It would be interesting to know who uses what programs for cnc on Apple computers running macOS? Surely there are such people.

I am the owner of a small CNC3018 Chinese machine. Here is a sample list of my programs:

easel (simple web 2d-cad)

candle (requires compilation from source)
grblControl (requires compilation from source)
Universal Gcode Sender
