Newbie needs help with 3 axis controller

[allanwinks]

I am a newbie about to start building my first 3 axis machine. I have chosen to use the 3 axis Stepper Driver Board with PC interface as the most cost effective solution for a complete beginner to undertake.

I would also like to make the 3 Axis Chopper Adapter but cannot find a parts list for it, can anyone help with this please?

The chopper adapter uses 100volt 19 amp p channel mosfets, I can’t find these is there an alternative please?

The page on your web site http://pminmo.com/3axis/3axis.htm was updated on 7/11/2007 , what was changed then?

Finally is or has anyone out there had experience of or used these boards before?

Many thanks the site is a great help.

If this question is about a board from Phil's site (pminmo.com), you might want to ask on his support forum at that site.

It was cosmetic changes. I changed webhosts and did a little clean up at the time. The chopper circuit is touchy, sometimes difficult for some to get to work. You will gte better performance out ot the L297uni for unipolars.
