woodguy - welcome aboard!
It seems both have their fans (or detractors?)! Are you:
1. Willing to build a kit? hobbycnc might be you answer - less money as you get to do the labor, or
2. Want plug and play? Xyoltex of the 2 choices.
You didn't say your plans - but as this post is in DIY router table - I'll take that as the plan. Just something to consider -- if you ever want to get a 4th axis set up going with the table - you might consider buying a 4 axis board at the get-go. You don't have to use the 4th axis right away - but its cost advantage becomes obvious downstream if you do want it -- Xylotex doesn't have a single axis card at this time.
Read the Xylotex pages closely. Jeff does a pretty good job of pointing out the difference between the 300+ and 400+ motors. You'll want to know what sort of speeds and torque you'd be dealing with -- and consider that when making a choice between the 2 boards.
I considered the hobbycnc - but not yet ready to break out the solder gun. There have been some posts regarding (some disappointments added) with the boards - but you see that with many things.
Unfortunately you can't get on the Xylotex forum (Yahoo) until you own one. (OOPS I stand corrected! Thanks LBJ)
I have 2 3 axis boards Xylotex (just got the second last week) and am building a multi-axis set up. Jeff has been very helpful in the process.
Hope that helps some - just one user's opinion.
:cheers: Jim
Experience is the BEST Teacher. Is that why it usually arrives in a shower of sparks, flash of light, loud bang, a cloud of smoke, AND -- a BILL to pay? You usually get it -- just after you need it.
