X axis of vibration at low speed
October 31, 2020 06:46AM
hi, i have a 3d printer with trapezoidal screws T8 and motor nema17 (17HS19-2004S1) conversion from motor to screw is 1/4. Motherboard BigTreeTech skr 1.4 turbo firmware Marlin. TMC2209 stepper motor drivers.

At low speeds (800-1300mm / min) or starts and stops, the engine vibrates.

extract from the console at speeds higher than 1300mm / min

Re: X axis of vibration at low speed
November 02, 2020 04:20PM
if someone had one problem. on the Spreadcycle the engine worked completely without a problem, but at the speed at which the engine was supposed to have the engine steps the steps I did a different conversion from the engine to the screw and everything works as it should
