I am new to cnc so bare with me please. I've had my machine for a little while but I got away from it for a year. I fired up the computer and it wouldn't come on. It wound up the power supply was fried. Mite have been hit by lightning. I got that fixed and install ed home and limit switches. I wired them with 18 gauge sheilded wire hooked in series. I sent all the axis to home which they activated and worked fine, so I shut down the machine for the day. The next day everything was at 000 so I moved to axis and re home again and the z moved to the +hit the home switch and stopped. Then the y move to the - and stopped along way from the switch. The x did the same. So I retried by going to move the z in the - but it hit the home limit again. It winds up that the + automatically changed to - but nothing indicated this anywhere on any screen. The other axis were the same. 1 other problem is that the z dro is not changing in either motion of the axis and all my of axis are off in calibration. Can anyone help me I'm getting frustrated.
