Hi, I am taking a class to learn about cnc. Have had a very limited time so far actually on a machine. So yesterday we were on a haas lathe doing our tool offsets. Was making about .010 cuts on this piece with various tools and teacher came over and looked at the piece and said we werent running the spindle in the right direction. So my question is a very simple one. When in MDI mode, and enter either M3 or M4, along with a speed, then push the green cycle start button, will it use the M3 or M4 setting that I told it to turn the spindle in forward or reverse? Or would it choose the spindle direction based on some other setting? I know on the control pad there are spindle buttons, fwd, reverse, stop, etc. But just want to know if you can choose the direction using M3 or M4 when in MDI mode?
Thanks
