Hi Hood
Did as you suggested and I get 3v on pin 16 so you're right. Therefore ,I have an output signal to the charge pump but with the charge pump enabled the drives remain disabled and don't accept the motor drive and direction signals.

Thanks again
Nigel

Best ask Gecko as I know there are definitely issues with the chargepump and the Smoothstepper. What I seem to remember is it is the setting on General Config page that turns off chargepump on E-Stop, disable that option and I think it works, so may be worth a try.
Hood

Its Chargepump enabled in E-Stop that the option is called so you will need to enable it and see if it helps.
Hood

Hi Hood, the "chargepump enable in E stop" was checked so I assume that's enabled. I did uncheck it to see what happened but no change.

I will ask the Gecko forum and let you know if a solution comes forward.

Cheers
Nigel

Hopefully they will have an answer

Hi Guys
I noticed that on my mother board there is a 26 pin male connector. I am wondering if this will be an on board parallel port and just needs a DB25 socket fitted via a ribbon cable.

LTP1 is listed in the device manager and can be configured to EPP as recommended by Gecko via the bios. If so then maybe this is a better option than the PCI board.

Just wondering if I should see if I can get a cable and give it a try. I am only guessing as to what this connector on the mother board is for.

Appreciate any guidance. Should I leave well alone?

In any event I can sue the machine as is without the charge pump. I posted on the Gecko forum but no replies yet.

Cheers

Nigel

Have a look in the BIOS and see if there is mention of a parallel port, if there is then that is likely what the connector is. What make/model is the mobo?
Hood

Hi Hood
In the Bios, under Advanced, super IO config. is listed:
Parallel Port Address [378]
Parallel Port Mode [options are ECP, EPP & ECP+EPP]
Parallel Port IRQ [7]

The computer is not a brand name, on the mother board the only marking I can see is G31-M7-TE.

This looks promising

Cheers
Nigel

As you say Nigel - This looks promising 

Tweakie.
