HI guys.  I built a machine a couple years back, using Xylotex hw for the breakout board.  I have an XP parallel machine, and got it working fairly well with generated gcode. I couldn't get the limit switches set due to my limited experience and the lack of capability or instructions.  I can configure a PC pretty well, just not very electrical.  I have, I think 23 and 45 steppers installed, three axis so far.  Is there a more common and easy to set up breakout four axis with limit switch controls?  Not tied to parallel, but I can make it work.  Yesterday, Geko was suggested.  No direct phone there.  I'd like a supplier that I could spend a few minutes talking with or has something more turnkey?  Appreciate the help.
