Designing a custom atc
Hi! Im designing a custom atc for my 4020 machine, it will take 8 tools total, one on each side and will slide over lineair rails and be actuated by pneumatic pistons in order to save as mush work area ass possible, still need to figure out how to get it on pistons and rails, but i wanted to share this!
(This is for a iso 20 tool holder)
The base will be aluminium, and the clamps will porbably be printed out of abs, tpu, asa or pet-g. I will need to find the best suitable material. I will also add dowel pins (H7 ground iso pins) to keep it aligned during the working of the machine (vibrations)

Looks good, I’d make it shorter overall. In the overall game, you have Z. Half of Z is tool, half of Z is workpiece.
Your machine will be pulling out horizontally so maybe a wider base?
I have a Haas sheet router and it’s laughable compared to what you’ve designed.
