Re: [CAD_CAM_EDM_DRO] How do set home position, running turbo cad/cam

Cassadaga717,
       I'm just a novice at CNC, my first thought about your question and save you money by not having to pay the fire department, is don't worry about limit switches for the time being, you can place them later, I have my machine working for two years now and still have no limit switches, when I produce a program in gcode, I do several dry runs on the computer only and once I am satisfied all is well then I start the machine and might do the first two or three steps in single block until I think its ok, (I am running Mach3),
 
This is how I survive with my machine, I'm sure you will get better advice, from other members, if not you could join the mach2mach3 forum on yahoo, they are very active,
 
Good luck, and make some chips quickly before its to late,

I'm in the final stages of my scratch built CNC and starting to look into the software to run my machine. I have a full copy of Turbo CAD/CAM 11 and after going through the CAM setup I noticed there it no way to detect the limit switches or to jog the machine to a home position. I used the Hobbycnc driver board and their 305oz stepper motors. Although there are inputs for limit switches, it said the inputs are for the software only. I've read all the threads on numerous groups and no one seams to mention about manual moving the machine. Please help, I'm so close and if I don;t get the CNC running, the wife said she was going to burn the wooden monster in the garage.
