RepRap: Blog

It looks a lot worse than it is, folks. Not that there aren't changes to be made. It seems to move as planned at first glance, but was an awkward print, and the 3DEA filament I was using had poor bed adhesion.

One of the Flexible Couplings I'd made from it snapped internally - source of my suspicion about the X Axis Driver - so I switched to eSun PLA+. Quality filament pays for itself in reduced reprints.

The top flexure doesn't print in a stable way, but that might be fixable with some tweaks to the top beam. Testing it shows the flexures to be a bit stiff, so altering their length/width seems like a good idea and I might fix the profile a bit (the code there is a bit bodged). There's also more torsion at the two ends than I'd expected. That might resolve with more flexible flexures, but I'll have to pay attention as to where I put the drive nut.

I'll test it more thoroughly anyway, but not today. My schedule is very packed for the next few days with a shooting competition, surgery consult in the city, and some family business. The end result being I'm probably not going to get much done for the next week or so other than pushing the odd update to github. Hasta la vista.
