Hi All,

I found this board that I bought maybe 10 years ago & I want to try it.

It was working when I got it but I dismantled it ages ago.

The company appears closed & their site is down.

Now I can't remember what to do about VBB IN. What voltage & more crucially, which way round are the two VBB connectors?

Which one is +ve & which -ve ?

Thanks !

Stepmaster is there with user manual PDF.

Sorry, can you be more specific? Where exactly?

The www.stepmasternc.com website is (AFAIK) gone.

The error I get when visiting that URL is "DNS_PROBE_FINISHED_NXDOMAIN".

Just google Stepmaster , I did just after I read your post. They don't sell them any more but the website is up with all the info.

You do know what googling is?

Your google must be better than mine.

If I google "Stepmaster" I get pages & pages of exercise equipment.

If I google "Stepmaster 4 axis cnc" I get pages & pages of exercise equipment + StepMaster ver 2.5 which is a defunct Russian board maker.

If I google "StepMasterNC 4 axis stepper motor driver, model SOP-1" I get links to this site
