After Homing and sending the NC file, Laser Unit rams into the Left Gantry Carriage
When the Emblaser attempts to find the (0,0) position in order to make the square bordering our laser cut design, the laser rams into the left gantry carriage. My partners and I attempted to tighten the belt tension, changed the firmware settings to default according to another post, and removing one of the screws on the laser unit near the belts that was the first contact of collision with the left gantry carriage. After attempting all of these fixes, the laser unit continues to ram into the left gantry carriage. On the other hand, the laser unit does not ram into the left gantry unit afterwards when it creates the border. How can we fix this problem, assuming that the collision is unintentional design?
