Toolchanging Machine [Duet3]

lavanyaarora

Hi,

I'm building a toolchanger using e3d toolhead and tools.

I have a duet 3.

I plan on having 8 tools, for which I understand I need 8 toolboards and 2 distribution boards.

Q1) can I use 2 distribution boards with just 1 duet (24V)

Q2) Would it be enough to power 8 tools? (6 hemeras with supervolcano, 1 laser module, 1 CNC milling module)

Q3) as for my CNC tool I'm really confused. Can I use any router? Does it need to be under certain watt and volts? Is there any website/company which sells milling toolhead which is small and programmable by board.. I mean I know I can control it's motion but can I control its speed? And would it be powered from mains or PSU

Thanks!
Happy Making

The answer to Q1 and Q2 is yes. However, as your laser and CNC tools won't have heaters or stepper motors, using tool boards to drive them sounds like overkill to me. You can drive them from the Duet 3 main board instead. Tool boards are great for direct-drive extruders.

I'll leave Q3 for others with more CNC experience to answer.

But how will I connect 6 hemeras to a single duet I will need some sort of expansion right

I also have 5 motors (3 for z)

I meant that tool boards were overkill for the laser and CNC tools. You can use tool boards for the Hemeras.

@lavanyaarora Where are you planning to have the rest positions for 8 tools? All at one side of the frame?

As for Q3:

What are you trying to cut? We might be able to lead you in the right direction. If you’re using the e3d tool changing system you will need a relatively small/lightweight solution.

E3d has come up with a small open source system for their tool changer machines designed to cut recently extruded parts called ASMBL. Link below.

I am currently planning a tool changer machine and this is the direction I plan on going. The tool changer mechanism and machine stiffness just don’t lend itself to much more than power and cutting capability.

@TC all at 1 side yes. Printed is over a meter tall and meter wide. Print surface is 615x615x640

@Alex-cr I have looked at it, I just wished they would source the parts, assemble and sell as a tool head. I would pay 2x the cost. Their sourcing guide is not good
