Problems with Nema 23

My next problem area is the motors. They are Longs Motors model 23HS8610
287 oz. Either I am doing something wrong or they are way under powered.

It looks like these are 6-wire motors. The first thing to do is work out which wire is which. The docs may well be completely wrong.

If you have a multimeter it is quite easy. The wires are 2 groups of three. In each group of three one wire will be the middle of the winding that the other wires are the ends of, and if you measure the resistance you can work that out.
ie, if red to green is 3 ohms and red to blue is 6 ohms and blue to green is 3 ohms, then red and blue are the ends, and green is the middle.

Once you have found the middle wire from each phase, tape them up and ignore them.

Then it doesn't really matter how you connect things, as long as one winding goes to A+ and A-, and the other to B+ and B-.
