My extruder experiment came out great and so I decided to go ahead and build a dedicated 3D printer

Build specs
8 x 8 x 8 inch print bed
Frame is 1 inch T slot
Bearings are T sot linear bearings - no screws, no smooth rods
GT2 drive pulleys and belts'
Nema 17 motors
Probotix drivers, breakout board and power supply
gnex lab dual temp control board for hot end and heater bed
8 inch silicon heater bed
I will run the code on Mach3
I cut the T slot pices today and did a rough fit to see how it looks
I don't have the UHMW-PE bearing material for my bearing blocks yet and so I just used cardboard for the mock up
Here's a pic of the progress so far
