I think I change 1040, 1041, 1042 from 0 to 1, any others? for metric to inch.
I'll check the sticky switch tomorrow.
The Z only went up, and severely overtraveled when I tried a zero return. I hand turned the screw to bring it back down, but I probably need to do a zero set for Z... still looking thru the manuals for that procedure.
The Z limit switch is located on the top right hand side of the machine. It is kinda behind some brackets and casting, but you can get to it.
You assumed wrong. You have to use gauge blocks, or like I did, machine a block to the correct length, bring the head down and touch the spindle nose on it. Zero the machine and move it up to a designated number and set zero. Then you have to move it back down to the next quadrant on the encoder. It's fun, you'll get used to it.
There is a lot of numbers in MM, but you don't have to change them. Also, on the offset screen, the decimal is moved over 1 place. Kinda crazy, took me a while to figure it out. So basically, if you need 2.000", you have to put 20.000.
I will post in a little bit about the Z home position.
I found a blue rectangular device about 1"x1"x2" made in Germany with a roller on the end that retracts about .25" when pressed, however, it does not contact the wall when the spindle over-travels. It needs to retract/extend about .75" for it to work, or I have to move the device closer to the wall.
Took it apart, and there seems no problem with it. when I manually retract the wheel, the DRLK comes on, so it does work.
Maybe the Z limit switch is somewhere else? I am still getting Z70 abs. Illegal and Z only goes up.
Give me a little bit. I gotta dig deep in the back of my brain. I have had this happen before. There is a way to go into the ladder and tell it that it is OK to travel Z-. There is something that is telling the control that it can't go down.
