We've been working on some new designs for the WorkHorse Printer. This is what is changing:
Updating the BOM
Reduced the weight and footprint of the Y-Axis Carriage
Experimenting with Igus anti backlash lead screw nuts.
New hotend mounts: E3D but there's a Slice Engineering coming.
New gantry plates with ZYLtech lead screw and ball screw
Now using Duet 3 Mainboard for better lead screw motion on the WorkhorseXL but currrently using Duet Wifi on the Workhorse 350mm x 350mm x 650mm.
Reduced the weight and footprint of the Y-Axis Carriage.
Experimenting with Igus anti backlash lead screw nuts.
Trying out different direct drive extruder designs
I'm considering making the X and Y-axis C-Carriage designs from solid rectangular bar instead 2" x 4" aluminum tubing. There will be a increase in wasted and machine time but the over all weight and footprint will decrease. The more compact design will allow faster printing speeds due to reduced deflection within the system.
