So - wanted to cut carbon, and finally found a safe and good method.
This has been cut with 0.2mm per layer, so i want to go faster and deeper, but im using slow feedrates due to not wanting water to overflow.
Basics; I built an acrylic tank on top of a 5mm acrylic plate. I left room for the plate to be mounted under the L bracket.
I then cut my carbon to size, and left two small pieces, which i stick under the L bracket, so the carving height is the same as the actual carbon position (due to it being on a piece of acrylic plate).
I then pour water into the acrylic “bath”, and presto!
It works really good, but i will need to find some good drill bits for this; Im using the lightblue smaller one (the middle one from here https://www.inventables.com/technologies/solid-carbide-upcut-fish-tail-spiral-bits)
Let me know if you have any questions, or maybe some comments!
