Hi Zax, They ran freely before attaching the belts but I will certainly try that today. They both move when in operation, but one of them seems to drag, almost like the belt is too tight.....yet when I release the belt slightly, the teeth don't catch correctly. I will try what you suggest and get back here with the result. Thanks.
@stephanlaser92 It is much easier to use a program to generate G-code but you can do it manually if you wish. I don't know about Elekscam but in T2Laser you can write G-code directly to the editor or load as a text file created in notepad or similar, then you would just send it to the laser.
@r14rojo It is a lost step, it occurs when the torque from the stepper motor is lower than the friction. So either the motor current isn't set correctly, your machine has a mechanical problem or you are exceeding the feed rate / acceleration limits.
