What DC voltage are you sending to the spindle motor.

The motor will run overspeed if it has become demagnetised but if you spply too high a voltage to it you will get arking on the armature and may cause permenant damage to the motor.

You need VR Turning provided you have an EPROM capable of running VR Turning.

Attached is the Instalation and User Manual for the dust extraction units supplied with Denford Machines.

Hi, Glad it seems to be working. You may have been better running the fans off the 24V supply as if you are using the 12V or 5V supply this will increase the heating effect on the voltage regulator on the control card.
Hopefully the cooling fixes this.

Can you supply photos of the inside of the electrical cabinet It sounds like the spindle analog card has failed.

Please send a larger picture of the spindle drive.

Wires 54 and 55 are the analogue
Wires 17 and 19 look like the motor DC

Can you make the voltage measurements on the spindle drive and report?

Measure the 0-10V DC analog input to the spindle drive.

It should be 10V at max speed. 5V at half speed. Is this voltage going up and down or stable?

Next measure the DC motor voltage going to the motor is this going up and down?

It could be motor brushes or the motor tachometer

You have a DOS EPROM fitted so cannot Run VR Turning.

Eprom is V1.6h/s

The PCB has a floating head which takes into account a surface not being flat.

Great Restoration thanks for sharing. .

The Z home switch is wired to Terminals TB1 and TB7 with Violet wires. We discussed how to view the Debug I/O in the software. If you remove the violet wire from the Z Datum input in TB 1 then try and home the machine If the Z home input is working the Z axis will think it is on the limit switch and...

What material are you cutting?
Have you measured the width of a slot made with your cutter? Is the cutter running true?

Try turning turbo mode off as the program reads ahead as far as the next modal change. The feed displayed will be the feed where's the program has read ahead to.

If you turn turbo off the machine will display the feed of the actual currently exicuted line.

As Pete has said the forum was set up as a place where users can get free support and information. We do not charge for the service and try to help where we can. I have read back through some of your unanswered posts and think that the questions are too vague and are not easy to answer. Denford hold...
