General Mach Discussion / XYZ have gone nuts again : MAch 3 and Chinese cnc 5040

« on: August 27, 2015, 01:10:31 PM »

Hello.
router have been running fine for a year or so.

But recently I started getting terrible drift on the Z axis...cutter going down an inch even on a shallow cut.

So I uninstalled and re-installed the software.

NOW it has got really bad.

Even with correct ports and pins and motor setup for my machine...the X, Y and Z arrow keys dont work the way they should.

X moves in same direction for both keys.
The Z buttons move the Y to the top when pressing either button.
And the Y buttons do nothing at all.

CAn anyone help with this?

Thanks,

Simon

General Mach Discussion / Help major XYZ axis problems after a 2 month break...

« on: June 30, 2014, 12:12:27 PM »

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
