Replacement stepper drivers, nearly silent!
« on: January 18, 2017, 07:59:49 PM »
I just installed TMC2100 stepper drivers on my printer, and have two more that will go on my laser. These things are amazing; they virtually eliminate all stepper noise and you're more or  less left with noise from belts, wheels and fans.

A little pricey at around $7-10/driver, but its more torque, less current and virtually no noise. They can also provide a digital output if it detects lost steps and some other stuff I didn't read very closely.

Its not compatible with the normal microstepping settings, so you have to remove or not solder in cfg1, cfg2, cfg3 pins, and wire cfg1 to gnd. Then you have to invert the direction signal in the firmware; and after all that they are basically a drop in replacement for the step stick clones.
