Gents,
I am having trouble with a new to me 640m. I will be programming in EIA, and will not be using the mazatrol side of the controller. When I try to teach in the tool offset page it gives me a positve number.
Lets say I have the machine at Z 0 in machine position, and I wanted to set an offset there. If I went into the tool offset page, hit teach, it asks me for the distance from tool tip to the table, if I type in 0, it puts a length offset of positive 69." IF I tell it distance from tool to table is 1., it puts in a lenght offset of 68."
For some reason, the teach function always add +69." to the lenght offset.
What am I missing? If type in the actual machine position, everything works great. Can I calibrate the the "teach" somehow?
Thanks in advance,
Steve
