Greetings to all the other stepper experts here. I got the double ended motors for an Ender5+ today.
Other than the paint job and wiring, leads instead of sockets, they look identical to the motor currently on the Ender5+ for Y drive. No perceived improvement.
I can probably program klipper to drive then both with a separate 5160 driver per motor, get another bracket, mount then butt to butt with one coil reversed, locked together with a 5mm to 5mm coupling,to maintain X squareness making them into one motor with twice the torque.
The big IF is whether the drivers always power up at the same state before any move is commanded, I don't want x square to be a random driver power up fight.
Its either make that work, or figure out some sort of a backlashless bevel gear from one of the 3 phase motors that are all nema-23's so far. That would be ideal if the fault line could be used to freeze things if it ever loses home by even one step. Something the 3 phase nema 23's can do automatically.
Best antibacklash is not a bevel gear, but likely a jackshaft from the nema 23 to a short shaft where the nem-17 motor is now. Even a 1NM 3 phase would be 200% of the torque of whats in there now.
Which way, two nema-17 motors, or a nema 23 and a jackshaft with 30 tooth pulleys, would you guys opt for?
Thanks for your thoughts! Cheers, Gene Heskett. -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
