I have been using Mach 3 for a couple of years without any major problems.
After a break for a couple of months, I turned my machine on and did the usual startup.
but….even though cables haven't been swapped the following crazy behaviour was noted:
If I use the keyboard or toggle for the Y axis, the direction of the motors is reversed.
The Y axis buttons on keyboard or toggle control the spindle!
and the up and down buttons or Z axis toggle, does nothing.
How can this happen?
Pins and ports look good.
Can anyone help on this?
Thanks
Simon
