Hello all, I have successfully converted an 80's YCM-30 knee mill to run on Mach 3 with the original SEM servos modified to accept US Digital encoders.
Have made lots of doodads with it so far, but want to up the proficiency / efficiency with regards to tool management.
Currently, my tool length compensation technique has been to touch each to to be used on the top of the workpiece and do nothing with the Z axis in the fixture offset. This works ok, but isn't practical / graceful or best use of limited shop time.
I've found references to using a 'master' tool in which whenever it is used, it adjusts the other tools in the tool table a corresponding difference. I.E.; if tool #0 offset is initially set to 1.00" (like on top of stock) and is later changed to 1.020" then once changed all other tools in the table change the same .020" difference between the initial 1.00" and the new 1.020".
Seems straightforward and logical, but I haven't found any detail explaining how to do it. I'd read on the CNCCookbook blog about using tool 0 this way, but was unsuccessful in doing it on my machine. Whenever I tried adjusting tool #0 nothing would happen.
Thanks in advance,
Daryl Stamp
