If the machine is fitted with absolute pulse encoders on the axis motors it may be that the batteries on the drive are low & then you will need to home both axis.

It sounds like the control in your Router has been retro fitted by a third party.

It would have been supplied with a Baldor SmartStep or DenStep running Denford Software (Dos or VR CNC Milling).

I would look on a Linux cnc forum or contact whoever did the retro fit.

As you say it is worth checking the MicroFlex spindle drive. If it has a error it will have a red blinking where you count the number of blinks to determine the error.

Hope the attached help

No we have never used the ethernet port.

USB & Serial but USB is faster.

In QuickCAM Pro when you get the CNC file Output make sure you have ticked "Select to produce files for manufacture on a 4th axis Rotatry Fixture" before you export the file.

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.
