Hello Jon
Thanks for the welcome.
I am thinking in the terms of a foot print of 20" outside on "X" and 24" outside on "Y" using 16mm rail on each axis and with a "z" clearance of maybe 2".
I will use this CNC for PCB's primarily . I am in the process of building the "X" axis now , and will slowly build the entire machine to se Mach 4 and either NEMA 17 or NEMA 23 Steppers, with a PDMX controller. Since I am using Centroid Acron on my larger machine I think this will be very adequate for my needs on the smaller machine.
Happy New Year
