first CNC router, where should my zero position be?4/30
I have homing switches and I'm unsure if my zero should be right after they are done doing there homing or if the zero is supposed to be the center of my build volume?
Sounds like an easy question, but not so much.
What kind of machine?
Mine zeros at the limit switches but I use a machine offset to set 0,0,0 at the lower left corner top of spoilboard before I cut anything. This is handled by the post processor.
Most machines home to machine zero, which is not the same as program zero. For every move the machine makes,it does the math based on all the offsets from machine zero.
You can try as my words: 1. Open the machine, and then ALL AXIS HOME, the spindle will move to left front of machine. 2. move the spindle over your material, down Z axis, can touch the material. 3. XYZ all zero. then it's zero position now. 4.Choose the file you want to do, the machine can work.
1) Servo motor or some stepper motor has Z-phase pulse, one pulse per circle. Some are called origin pulse, index pulse etc.
