I just started using a 3d cnc machine to mill mdf boards. the router i'm using has a 5 feet x 12 feet working area and i'm machining a 12 feet model aircraft wing using mach3. i'm using catia for designing and to generate the machine code. ths is a locally made machine and i'm not aware of the controllers used in it.
the problem i'm facing is that the machine looses it's zero...mostly in the y axis. i'm constantly stopping the job and rechecking the zero and everytime the x and y wanders off of zero. last i checked the y was about 8mm off zero.
i've read somewhere else that interference can cause similar problems and since i'm in a workshop i did have some welding and grinding connected to the same circuit. i've eliminated that but today the machine went 2mm off in the y. is there something that i need to be aware of?
also, i'm thinking about using a stabilizer; where the main is connected to the stabilizer and the stablizer is connected to the machine.
i don't have a zeroing jig yet; i've seen quite some videos on youtube where they zero it using the autotool button in mach3. wuold be great to zero the x, y and z using the mach3 autotool zero function; so if anyone knows a resource for making the jig with the vb code; please list it here.
sorry for the long post, but need help desperately.
