Nema 17 mount EQ1

Stepper motor mount for eq1 telescope mount for sidereal tracking. I'm using T60 6mm pulleys for the worm gear and T20 5mm for the engine.

I'm still having trouble making the Arduino adjustments and code.

I will use an Arduino nano, TMC2209 driver (in 64 steps ms1 Low and ms2 High) and Nema 17 40mm 1.8º per step (200 steps for 360º). I know my wormgear mount has 100 teeth. 100:1 and reduction 3:1 (60 teeth and 20 teeth GT2) Belt 170mm. STEP_DELAY = 22439; //22439 in 64 steps or 44879 in 32 steps.

See the calculations on the website, it explains very well how it does it if there is any difference.
