Alternative hotend assembly and cooling?

[Alex]

While I found that the stock cooler worked quite well, I was so used to the focused cooling that you are referring to here. I’m using this: https://main.eva-3d.page/
But be aware that you need to modify the X-axis (and parts of the hotend assembly)to be able to mount it on the Gridbot.

Edit: And I am about to build siegfried’s solution as I find it very compelling

Thoughts on Duet Boards for future expansion

Howdy again, just now coming back to this having finally assembled and tested this. I’m not currently hosting the files anywhere, but I’d be happy share more details if you’d still like them. I still need to tweak the design to use the optical endstops stewart suggested. While it’s not really a Grid bot anymore, I tell anyone that asks how great of a place the gridbot is to start.
