Board needs some fixes but all home made boards have their issues.
Pieces stacked up for a look see.
Servo Shield Pins, Red +3.3V, Black -3.3V, Orange Z+ End Stop. Requires G Code to be edited. Z up = M5, Z down = M3 SO30
can make this PC Board Plotter Scratcher with simple tools. A
band saw and drill press will work fine. This does not have to be
pretty to work well. It needs to be square. You can use the
glides and rails to make the two rails parallel. This uses Core
XY. I use Dykem a bluing for coloring metal in machine shop for
scribing lines. It holds up well to the etch. It scratches
easily that is good and bad. Handle with care. You must edit the G code calls for Z up and down, to be appropriate for the servo. I use DipTrace, Flat Cam and Universal G Code Sender. I use home made Drill Press to drill PC Board. See the drill press on this site.
