Each machine and its various components are unique and may require some alterations to dial in the settings. If you are experiencing issues with the gantry movement or skipping steps, this guide is a starting point for […]
Connect your Z-table into the Z axis header on the LaserBoard using the built in driver. The external stepper drivers, accompanying cables, and the additional power supply are not typically required unless you are wanting to work with heavier projects, have a larger machine size/bed, or are using heftier stepper motors. For additional info: Cohesion3D LaserBoard Buyers Guide If you […]
Setting the Correct Size for the Y Axis When the head homes to the rear left of the machine, it thinks it is at 0,200 (where 200 is the default C3D config file value for a stock K40’s Y axis size). So when you move to the front, you are moving closer to 0,0. The […]
Rotaries from LightObject or Cohesion3D should work directly off of the board with the built-in drivers. Plug it into the A motor port on LaserBoard, configure, enable, and setup in LightBurn. Rotary types / settings will vary and need to be dialed in based on their specifications, but this guide can be used as a […]
Changing Stepper Motor Currents If you are experiencing unexpected performance with stepper motor motion, this guide will help you troubleshoot the onboard drivers. These steps are not relevant to external stepper drivers. May present with the following symptoms: Laser head movement is jerking, crashing, or erratic Stepper motors are skipping or engraving is shifted Stepper […]
