looking for some assistance with a stepper motor project ( Screw driver )

[NorthWheels2024]

Hi everyoone,

I am new to the CNC world. I am building a screw driver application that is required for a part of wheel assembly we are doing. I am not sure where I can find this help.

I have a steeping motor mounted with a handle and a custom made chuck. This chuck need to turn a certain amount at a desired speed stop and then repeat. This will be controlled by pedal activation. The program I loaded is Drufelcnc. The communication works but it requires G Code to fuction. I have done some reading on Gcode but not sure how to mange this in the software or write it for this purpose

The process ( Chuck interface must start and stop at an exact location ) and reapeat with the pedal activation.

Stepping motor: Nema 17 1.2A 17CA02A-120
Driver: DM556
Motion controler: Breakoutboard Mach 3
Pedal: Foot pedal
Software: Drufelcnc

Thanks for any assistance and guidance as to where this information can be found

I'd never heard of DrufelCNC, but according to the site. it seems like it takes regular G-code. https://drufelcnc.com/?c=gcode To set the units to mm, give it an initial G21 command. To make it go along the X axis to a particular location at a certain speed, you'd give it a directional command like G01 X2.35 F200. But making it respond to a foot pedal will take some electronic assembly and integration at your end. I suppose if worse came to worse, you could rig your pedal to tap a key on a joystick: https://drufelcnc.com/?c=manual&p=m21

Hi North - The pedal is required when you are using your hands to do the work. Your using DrufelCNC controller, just use cycle start on the screen. Peter
