Hey guys,
Its been about a year since I worked on my Bridgeport boss 6 retrofit.
My problem is when I start the spindle using MDI, my z++ limit trips .
-My z++ limit and z home is shared by a optical sensor via pin 12 and normally closed.
-My z--, x++,x--,y++, and y-- is in series via pin 11 and is normally closed using mechanical switches.
- I do not have and x or y home switch yet.
When I home the z it homes correctly.
When I exceed the z++ limit it trips correctly
however, like I said when I start the spinlde via mdi through mach3 (T1S1000m3;) the z++ limit trips
I know its the z++ limit because when I deactivate the z++ in the inputs page, the spindle runs and does not trip a limit.
I do use a vfd in my machine.
Has anybody have had this issue, thanks Joe
I plan to finally post pictures of my design shortley thanks to all those who have helped me (hood).
