Motor problems/

[erniehatt]

Hi, hope everyone had a great Xmas.
I have built my new machine, all is well, except the X axis motor, it runs but not as expected.
I jog the motor in the + direction great that is the way it runs but if I press it a second time it runs in the opposite direction, same with the _ direction.
Is this a setup problem, or the driver, maybe the motor is stuffed.
Any suggestions would be most appreciated. Thanks.

Check the step & dir wiring.

But knowing what controller you are using may help.

The controller is the NVEM v2 6axis controller and the motor driver is DM542T

Double check the wiring, but I can't think of a fault that would give you those kind of symptoms.

What does the X-axis DRO show on your controller?
Is it behaving how you'd expect (increasing when you jpg +, and decreasing when you jog -), or is it following what the motor is doing?

If the DRO is doing what you expect it should, then I'd try swapping drivers around, or at least swap step/dir wires with another axis, and see if the fault moves.

Can't check the wiring at the moment.
When I jog + it goes in the direction that it should, but jog again in reverses, jog again in goes in right direction , and so on, the - acts the same.
Externally the wiring is correct.

Unfortunately I do not have a Dro. As soon as I can get into the shed, I will give a test run and see what happens there.

How many steps are we talking in each direction ? One, many, a number that is always the same or a random amount ?

What do you mean you "can't check the wiring" but "externally it's correct" ?

It will travel in the one direction as long as I hold the button, as soon as I stop and repress it, it goes in the opposite direction.

I checked the wiring from the motor to the control box via a Drm. But at the moment I can't check inside the control box as it is so darned hot in the shed. I check the external wiring before posting here when it was cooler..

I feel for ya.....Yeah summer is here, so will we have floods, fires or both this year ? Or is the gumberment going to require QR codes for natural disasters ?

If you run MIDI commands how does it go ?

I think m_c was referring to the on screen DRO, I guess you are using one of the MACH variants ?

Say That again, it gets to about 40c.You may well be right who knows what they will decide on next.
Yes I am using Mach3.
Not sure what you mean by running Midi commands, I believe they are for music.
I am wondering what will happen if I run a dummy Gcode, may tangle itself up.
