I bought this Folgertech FT5 R2 FDM 3D printer. I made a number of improvements to it, including AC heat bed, TFT display, Titan Aero extruder, Volcano hot end, etc. The previous owner had a Titan direct drive extruder where the extruder step motor was bolted at the back to the tall backside carriage former. Printing showed waves on angled surfaces and I noticed a significant amount of flex in the whole extruder/hot head assembly. Thinking about replacing the whole carrier, I opted to design a clamp that would leverage the front side of carriage to clamp that print head assembly into submission. This is the result.
