Are you putting a voltage through the switches or are you connecting to ground?

Mach4 General Discussion / Re: Turn | Is eccentric turning possible with Mach4?

« on: October 08, 2019, 07:45:21 PM »

Here is my experience.

If you have an eccentric that you can approach from the Z axis you can use the XC way to produce the eccentric.

Tool stays on the centre line and the C axis rotates and the X axis moves in sync plus and minus to follow the shape while feeding to depth in Z.

If you are in a groove like a crank journal then the only way is with XY & C axis,  the X&Y do a G02/3 move that is the same radius as the offset of the eccentric while tied to the C rotation.  This is milling mode on most lathes. So

The main problem is the max RPM, I could only do 400rpm and that was on a Mazak Integrex i400S with a smooth control. There was nothing faster at the time.

You also need a Y axis to keep the tool on the centre line, you are in effect producing a circle with the tool in the XY plane.

That should not be a problem, just add the M1100 to the end of your program and it will work.

How did you want it to work?

Try a different DRO, #1200 may be in use by another macro

I seem to remember its unit neutral so all you do is adjust the figures to metric values

Work out which of the microstep drivers are connected to the Y axis and the Z axis, follow the cables back to the control or they may be marked on the box. Swap the drivers in the box over and see if the fault is transferred on to the Z axis.
