Do I wire anything up or not? I'm getting mixed information here.

If it's any help, I have a machine with the Enable / Disable connections on the drivers wired up and in 15 years I have never had the need to use the Disable function.
If you think you may want to use the Enable / Disable then by all means wire it up but I doubt you will ever use the function unless you have a specialist application. My advice would be to leave those terminals unconnected but the decision is yours.

So I have to wire the ENABLE+(+5V) to my +5VDC power supply and ENABLE-(ENB) to a output on the controller?

If you want to use the Enable / Disable function then Yes.
If, on the other hand, you do not want to use the Enable / Disable function then leave them unconnected.

From the data sheet the manufacturers of the drives say that if you are not going to be using the Enable inputs then they do not need to be connected.

Anyways I think the problem with relay triggering might have something to do with lpt port, once I connect lpt cable relay just triggers on it's own, I found an old bob and plugged in does same thing with relay, changed lpt cables same thing,

Identify which LPT pin energises the relay than change it's Active Low state in Config. / Ports & Pins / Output Signals - does the relay still energise ?.

Hi Naeem,

I am concerned that you BoB is extremely dirty and that the contamination may be electrically conductive - if the same applies to your PC (or if your PC can become contaminated in the future) then you are jus heading towards failure. Sorry to be so critical but unless you tidy everything up first (the soldering and twisted wires are a joke) you stand little chance of achieving any sort of reliability from your plasma machine.

No. have them set at 1A, stepper controllers can go to 2.5.

That is Current - What Voltage are you running your steppers at ?
Are you running them at the maximum Voltage that your drivers allow ?

(basically Current determines Torque and Voltage determines Speed).

I tried you suggestion and X1 did indeed move by 1 mm, it took fifteen seconds though.

When MDI testing type G0 X1

If necessary return to Motor Tuning and adjust your Velocity and Acceleration settings to set the axis speed then save the changes.

I must be getting old.!!!!!!!

Naaa, you have years to go yet
