Hi,
I'm working on a simple extruder and GRRF hotend mount, and I think I will design a new carriage plate. I attached a picture of what I have in mind.
As you can see, I made a lot of holes in the plate, to help mounting things (I need to redesign my
air cooling system).
My main concern is about the heat: the ABS I'm using need a high temperature (~255°C), which can melt the hotend support... I made a test with a design close to this one, and the ABS didn't resist to that high temp. I think this is mostly because of heat generated by convexion, as the big nut is also at a high temp.
So I'm looking for a thermal barrier I can glue below the hotend mount. Any suggestion for that?
I'm also waiting feedback to this complete extruder design...
Thanks!
PS: I already use the extruder part, and so far, it works fine. As you can see, I don't use any spring.
