ORD Hadron Wiggle in Z Supports
Posted: Sat Aug 17, 2013 8:45 pm
Hello forum,
I've disassembled and reassembled my Hadron in hopes of solving this wiggling that I observe in the Z supports. Tightening all t-nut bolts doesn't eliminate the problem.
The wiggle occurs during y-axis moves and becomes especially obvious at certain frequencies of infill and gap fill. The swaying of the z supports is slight but easily visible. The sway translates into vertical movement of the nozzle which will become more pronounced at greater z heights. I can't be sure if this motion is the root cause of my non-smooth print walls or messed up top solid layers, but I thought I'd ask the community if it has a solution or can assure me these wiggles aren't a serious concern.
My biggest printing problem at the moment is the inability of my printer to make a smooth top solid infil. Holes develop and though a different filament multiplier may solve that issue I thought the wiggling might also be a contributing factor. I've dialed in my extrusion rate so that walls don squish and bottom solid infill is full without piling up on the nozzle, so I'm pretty sure the multiplier is as good as its gonna get.
Any suggestions for a solution for the top solid infill?
My Hadron is driven by a Printrboard Rev D, uses a Wade's Accessible Geared Extruder, and a Ubis 3mm Hot End with a .4mm nozzle.
I'll add some pictures to this post when I get home later.
