Are you able to check that you have 240 volts going to the spindle drive unit?

Does it have the Brown Prestell Spindle Controller?

It has had a different spindle motor fitted & also the electronics are not the original that we would have fitted.

I guess somebody on the Forum will be able to identify what make of control it is now.

The PCB Engraver was never added to EasyUgrader & the PCB software does not look for it so no it does not need to be programmed.

You can put the machine serial number in if you want but it`s not required to run.

It is possible to do rigid tapping on a TU150 fitted with an OT-A control.

We only fitted spindle speed encoder & not a position encoder.

Hi George

Can you send a video to technical@denford.co.uk

Can you post a copy of the program please.

It sounds like it will be due to the depth of cut with the second pass slightly deeper.

It may be down to the internal RS 232 lead.

It would be best to make up a 9 way to 9 way lead to connect the machine directly to the computer.

What machine do you have?

I am not aware of the 6000 Diagnostics.

Have you set Diagnostic 453 bit 0 to 1?

You will need to adjust the tension as per the attached link with a tool in the spindle.

Have you installed the 450 Diagnostis?

Hi David

The spindle reverse was never an option on the Novaturn.

The M3 & M4 commands will both run the same way.

I presumed you still had the original control fitted.

I would look at keeping the axis drive signals as far away form the spindle drive & spindle motor wires as possible.

Can you post a picture of the inside of the electrical cabinet. I presume its a rack mounted control & drive fitted.

Can you supply the serial number & date of manufacture please.

We are in Brighouse, HD6 1QF

We would not be able to test it with it being converted to Mach 3.

Yes that's a distance from us.

Where are you located?

It would be unusual for the E-Stop switch to short out.

Do you have a electrical meter you can use to test the 24Volts DC supply & see if it is being dragged down?

It does look like the 24volts DC is being shorted out by something.

With it being updated to Nach 3 I am not sure where to suggest to proceed.

Did you upgrade the machine yourself?

Yes if it is the coil causing the issue.

It could also be the zero speed output from the spindle drive.

Se how you get on.
