3D Chameleon MK4 Zapp Edition Motor Configuration
3D Chameleon MK4 Zapp Edition Motor Configuration
This is an important step which must be taken when creating your own 3D Chameleon kit so make sure not to skip this step
This product is configured for Nema 17 Stepper Motors. This Tutorial can be skipped if using these motors.
Alterations to the Stepper Motor Drivers are required in order to operate other sized stepper motors. DO NOT SKIP IF YOU ARE USING ANYTHING OTHER THAN NEMA 17 STEPPER MOTORS! DAMAGE TO 3D CHAMELEON PRODUCTS WILL NOT BE COVERED IF CAUSED BY MISUSE OR FAILURE TO ADJUST THE STEPPER MOTOR DRIVERS CORRECTLY.
The stepper drivers may need to be re-configured depending on the stepper motor it will be running. All units will come pre-configured to drive nema 17 motors (like the ones which come with the ender 3 and drive the Z axis)
Should a different size motor be used, the stepper drivers will need to be adjusted to allow more or less current through to the motors to prevent damage and ensure correct operation.
NOTE: it is recommended not to use anything smaller than a nema 17 motor
To adjust the stepper drivers, a multimeter and screwdriver is required. The positive terminal of the multimeter will need to be attached to the screwdriver used to turn the screw on the Stepper Driver, while the negative terminal needs to be connected to ground on the stepper driver.
There is a great video below showing how to adjust the stepper motor drivers based on the stepper motor selected, please watch from the linked time until 4:28
NOTE: Be Extremely careful when adjusting the potentiometer as its easy to over adjust and damage the stepper motor driver. This will cause it to send full current to the connected motor and then damage it too. To overcome this, make sure the mustimeter is connected to the screwdriver when adjusting and go slowly like in the linked video
Tools Required:
- Multimeter (with Aligator Clips)
- Small Screwdriver (Philips or Flat Head)
- Patience
