Not many updates recently, but I will post a picture of Artifex, the printer I built last year.Artifex works remarkably well, it is based of of the Ultimaker design. It uses linear sliding bearings in the guide blocks closest to the frame and linear bearings on the extruder carriage.
The problem that I had with Artifex was getting the holes in the extruder carriage perfect for sliding bearings before I decided to go with linear bearings.
.9 degree nema 23 steppers around 2 thou per step at 8X micro-stepping

PID control for extruder and bead

In the coming days I will post about my projects from last year. I hope to start working on my printer again soon.
Future Posts include: Pictures of a few prints, an interesting problem that caused prints to print crooked with no obvious pattern, making an extruder carriage out of urethane resin, maybe a clip of my printer doing the imperial march, and I may even include some pictures of my non printer project the "Skate-Cart" a gocart skateboard combination death trap of a device. I was even working on a Semi easy 1.75mm to 3mm swap for the MK7, only because I have some 3mm plastic left.
Well thanks for reading and enjoy!
