Reply To: Thread Rod Drive.



The ~600mm/m max on Z is due to the 1/32 stepping on the drivers and the Arduino running out of puff generating the signals needed. I’ve set mine to 1/8 stepping and can get ~840mm/m, it’s not 4 times original-speed because of the mechanics, but the CPU seems happier with cycles seemingly spare now and it’s a nice speed upgrade. With larger thread, expect more friction, and I guess don’t expect twice the speed.
