Z-Axis stabilizer for Printrbot LC - not plus.


Print it out, bolt it on. Your printer bed and/or heated bed will need to be elevated to account for the 10 mm height of the part. I just used the plastic spacers included in the Printrbot kit.

Adding these completely eliminates the z-axis wobble!

I also added the Solidworks file.

Notes from a noob:

Installed on just one z rod showed it was more sturdy that the other (wiggled at the with finger)

Problems experienced:
. Had to drill the mounting holes a good bit larger to line up
. Had to drill z-rod hole slightly larger
. Z-Rod leans towards the bed (issue with my print or screws nearest bed pulling it?). This was the biggest issue. I used a framing square to verify the lean.. if not reasonably vertical the z-axis will not seat correctly once it starts moving

My calibration is almost perfect according to calipers and and a the 10cm Square file on this website. It's a very recently assembled Printrbot LC

Next I'll try http://www.thingiverse.com/thing:55053http://www.thingiverse.com/thi... It is attached with only fore/aft screws eliminating the possibility of being tilted to the left
