Denford Software & Machines

I do not have the ability to override the speed of my router manually. Any suggestions?

It could be a faulty pot, or a wire has come loose, or faulty soldering. Check the back of the pot with the power off to check out. Also, sometimes the wires become kinked or the soldered legs become bent.

You possibly have the wrong machine selected, or it is a machine with none standard setting (you would possible have a machine personality disk in this case)

Anyway, it should be a case of setting the parameters to tell the software whether your machine has got an override pot fitted or not.

Go into Setup > Machine Paramters > password: denny > Machine_capability - speed / feed pot fitted ?

I have had the same problem on 2 Compact 1000's - both less that 3 month old. I checked all the wires on the back of the control pot and jiggled them around. This worked on both machines. The contacts must vibrate close together during machining.

The speed override on the compact 1000PRO is a potentiometer wired into the controller card. There is a potentiometer for both the FEED and Speed override.

These pots are wired into the controller card on TB4.

The Blue wires are 0V, the Yellow is the feed override and the Green is the speed override.

The pots are supplied with a 5V supply from the NextMove control card.

If either of the pots does not work first check the other pot. If that works then you know the power supply is OK.

If you have a multimeter measure from any of the 3 blue wires on TB4 to the Green wire. The meter should be set to DC Volts and the black lead goes to the blue (0V wires). If you adjust the speed override pot the voltage on the Green wire should change from 0V - 5V.

The same test can be done on the Yellow wire when adjusting the Feed override pot. again measure from the Blue wires to the Yellow wire.

The potentiometers are a carbon film type which means they have a carbon track which the pot wiper runs on. The solder tags on the pot can flex which can sometimes cause the wiper of the pot to make poor contact.

If the pot does not work just try bending all 3 solder tags a little and this may resolve the problem. Also check the solder joints on the potentiometers.
