Cannot configure default E step stepper motor nema 23 for extruder on TH3D

Initializing

After changing your firmware, you always need to overwrite the old values in the SRAM and EEPROM with those from the Firmware. Which you do with M502 & M500:

Installing firmware does not by itself alter the EEPROM, so these settings needed to be seeded into SRAM via M502 and then saved into EEPROM via M500.

You could also run a G-code that has only these two lines:

M502
M500

Altering the EEPROM

Via command

Alternatively, you could access the printer via a terminal and send the command M92 E415 to overwrite the SRAM directly, then M500 to save the new setting to EEPROM. The associated G-code that only alters the E-steps/mm would read

M92 E415
M500

Via Software

Or you use a terminal that supports direct alteration of the EEPROM, like Repetier Host.

Cloudray Stepper Motor Series has set the standard for quality, reliability, and durability in stepping motors. The precision of our Torque Power motors is matched only by the dependability of their performance. All Torque Power motors are bi-directional and totally enclosed with permanently lubricated ball bearings for long-lasting, smooth operation.

Low vibration,Low heating, No loss of step
Fast Response,Better Acceleration Performance
Thanks to a robust design they can be selected for the harshest environments. Precise, open-loop, speed and position control can be achieved with the application of full step, half step, or microstepping electronics.

Higher Resolution，Avoidance of Resonance Regions
Stepping angle is adjustable( rang in 18°±5%）， 0.9 °stepper motor's stepping angle is smaller, fineness is higher and positioning is more accurate.Avoiding vibration,runs more smoothly and gets lower noise.

Robust assembly, high speed range, and exceptional performance in even the harshest environments make Cloudray Stepper Motors the perfect solution for demanding positioning applications.

Cloudray stepper motor and Stepping Motor Driver are widely used in engraving machine, cutting plotter, textile machine, 3D printer, medical devices,stage lighting equipment, robot, CNC machine, music fountain and other industrial automatic equipment.
