Right I need a lil help design inspiration-wise. I’m trying to work out how I’m going to mount the spool and extruder to the top of the AX-02, on the pictured plate. I know I want to use the centre 10mm hole to feed through, I know I’m going to want to mount 2.2kg spools on it. It’s rare that I can’t work out how to design something, but I’m a bit on the stumped side. Couple of ideas I have had is to go along the style of @Alex_Skoruppa 's Carbonoid or just dropping a roller spool holder on top, the latter being highly inelegant as a design solution.

Extruder-wise, I’m working with the Schlotzz extruder for the moment, until funds become available for a Titan. I have thought about designing my own extruder solution, but I don’t have the motivation nor time to sort it, when I can plonk a Titan or Schlotzz on it and be done with it.

Any input would be appreciated…

Mount the spool on top, with the filament pulling through the center of the spool down to the extruder, which is mounted on the underside of the plate.

With the spool pulling through the center, you don’t need it to turn.

@William_Steele - got an example?

Take a look at the Solidoodle Press review on Tom’s guide. They have pictures of their implementation. However, their’s wasn’t really good because the extruder moved around… in your case… simply mounting the extruder upside down and pulling from the center should solve the filament breaking issue they had.

You can look at the SeeMeCNC Rostock Max for how they mount their extruder. If you place it in the center, it won’t be in the way of the effector arms.

Alex, aye, I’m just impatient. I’ll probably go with the roller to start with as I have one knocking about. As soon as the frame comes in I can get it built and look at positioning with it in front of me.
