It really depends on how much of a risk taker I am. $9 or $10 for a single axis 3977SED board. Double sided, solder mask. $6 or $7 for a ultra simple 4 axis interface board. Single sided no mask or silk screen.
Probably could do 3 single axis driver boards and a simple 4 axis interface board as a package for $33 to $35. If I am in a risk taking mood and order a bunch, price could go to less than $30 for the 4 boards.
Component costs for the interface board would cost a person roughly $5 depending on source. Component cost per driver board would run around $17/board including the 3977. So total cost for a 3 single axis boards and an interface would run around $90. USD For those that had access to 3977SED's aproximately $72.
Or hardwire the DB25 to the 3 single axis boards and skip the interface board. $1 for a DB25 and a dozen or so wires.
A 3 axis assembled and tested Xylotex is $152 shipped.
