Title: Quadrant and spindle issue?
Post by: PSL on April 24, 2015, 04:09:48 PM
My mill is almost back up and running after a computer crash. If I do a simple program in quadrant 1 (x and y both positive numbers) in Cad. I then move to CAM and everything is good. I run a post processor and all is good on the simulator. I then open up mach3 and load the program. The spindle runs in reverse and the program flips and starts to run in quadrant 3 (both negative numbers). It is like it has mirrored itself. This never happened until the new computer. Is there a program error or am I just doing something wrong? This sounds strange but it is happening.

I went into the config settings. Went to homing and limits. The first column was all red "X". I changed the x and y axis to green checks. That seemed  to work for the mirroring and quadrant issue. I do not know if that is the correct way to fix the problem. I still have a spindle issue. It still runs CCW when I want it to go CW and vis versa. The other strange part is that when my z axis is at zero and I raise the z axis, my DRO readings show a negative number not a positive number. It shows my that I am lowering instead of raising my Z axis. Any ideas on this one?
