Tips on Nylon?
#1
So up to now I've been printing everything in PETG and bonding the parts using a combination of weldon 16 and 3dpen welding. I've just received my first roll of bridge nylon and after much trial and error, have dialed in my print settings to something I'm happy with...

My question is, if I opt to print the foot frames in nylon, whats the best way to bond nylon parts together?

I don't know that you need nylon for the foot drives.  I printed the motor mount and the omniwheel side riollers in Nylon and the rest in PETG. The frames are strong ( I think I used 5 perimeters and 35% infill for the PETG.  You can solvent bond PETG with purple PVC primer and all-purpose PVC glue. I ended up using the single-belt design. I could not get the dual belt system to stay on.

I would print the frames out of PETG. You can even print the motor bracket using PETG - Michael shows them as being printed in nylon, but I believe even he ended up using ABS for the brackets.

The only thing I ended up using nylon for is the omni wheels.
