I’ve had a lot of people downloading the drag chain system I published on Thingiverse, and several have asked for a Burly version. I’m happy to say that I’ve finally published two options for Burly at https://www.thingiverse.com/thing:4032440.
Even though my machine is running great, I’m making the transition to Burly because I’ve recently found some cracking in the roller prints. Not sure what’ causing them but as they are fairly far away from the nut I’m pretty sure it’s not overtightening. The cracking is along the print grain. Since I have to do the teardown I thought I’d also do the Burly prints.
I was thinking of doing something similar so you’ve just saved me a bunch of design time. Thanks! I’ll have to see how it lines up with my existing system or maybe just print everything.
That works, too. I designed the drag chain attach structure to fit on either the XY or XYZ part because of the persistent warnings to not attach to the Z axis to avoid stability issues.
If you’ve had the Z axis slip on you, you might want to look at the strengthened parts I designed also. Instead of just a friction fit on the top of the Z axis for the bushing and servo mounts, there’s a screw that secures them in place. One slip that punched through my spoil board was enough…
Mine are printed from PETG, so they’re cranked down. There’s zero chance of the motor mount slipping off the Z extrusions. I’ll look at the retrofit option since my system is fully printed already.
Zip ties for the wires coming out of the drag chain for the pair to the far right. The others are holes to mount a terminal block that I use for spindle connections. You can kind of see them on the original Thingiverse posting.
