hi guys
what do you think about that

That’s pretty slick. I would love to have something like that working for me. I think this could be made to work with the MPCNC. My only concerns are:
- In his demo video he spins the router between tool bit changes. I assume (could be wrong) that is intended to tighten up or loosen the collet a little. Before it engages the bit and gets the final tightening torque. I worry that may not work as well on the DW660 because it (the nut) is smaller/lighter than the spindle he used. Probably not an issue but it came to my mind as a possible issue.
- Something like this will come at the cost of X or Y workable space. It looks like you would have to use about 20 cm to fit this in. Since the machine uses up about 28 cm in X and Y for structure that would make it so the machine workable area would be about 48 cm less than the table footprint. Personally I think it would still be worth it. But the machines will need to grow bigger. Unless this is something that can be installed/removed from job to job as the need arises.
I guess with dw660 or similar this approach will not work at all. His spindle controlled from firmware and it seems he use low rpm and also reverse rotation.
The main idea to use force of moving x/y. He uses 40 degree (of the carusel) movement to tight the nut. But it’s not necessary to use circle. It could be parallelogram when bits located along one side.
But there is one potential problems.
-
What if a tool will not drop down? Use magnet? Is it enough?
-
how to handle tools with different length
-
how to change a tool and also the nut. The case when a few tools are 1/8 and a few are 3mm
also it seems Frank had improved his ATC
That’s cool.
Looks like he’s using a collet on the bit so that the height to the tip is the same on all the bits.
The upgraded one looks more reliable while possibly a bit slower.
