Can you post a picture of the electrical panel. There should be more than 3 fuses.

It sounds like you have an issue homing which may be as simple as a axis drive fuse.

Can you post a picture of serial plate & the electrical cabinet.

Yes the battery can be romoved.

It does look like the board is the issue. It looks to be displaying a "i" from the picture which is not correct.

It sounds like you don`t have any voltage to the axis drives.

If you try to connect does it detect "guard open & e-stop" ?

If it does check the fuses. There is one one the control card on the bottom right.

I can see that the internal cable is a 4 wire cable but the 9 to 9 is the best way to test.

Some of the earlier internal RS 232 cables were 2 wires.

It would be best to make up a direct pin to pin lead to connect directly to the control card.

You can use a standard USB to RS 232 adapter connected to the original serial lead to connect to the machine.



If you email through to Technical@denford.co.uk we can give you a price for the licence for VR CNC Turning.

Can you post some pictures of the serial label & the control unit.

Not sure why the currents differ so much.

Hi Toby

The post is fine.

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.
