Final touches on the CNC

My new CNC machine is cutting tricopter frames like mad and is working like a charm.

However when I built it I did the bare minimum just to get it going. Now the time has come to make the finishing touches.

I’ve been running the machine with the stepper-motor controller unprotected. That is until now. Now it’s going to get a home.

CNCU4
This plastic electronics box should suffice.

CNCU5
I used the CNC to cut holes for the fan and air inlet in the lid. Is it weird for a CNC to cut parts for itself?

CNCU1
I made the front and back panels from 1.5mm black G10 (fibre glass).

CNCU2
I think it turned out pretty well.

CNCU3
The connectors I chose for the motors are originally made for microphones, but should work just fine in this application as well.

CNCU6
Backside of the motor connectors.

CNCU10
Fitting everything (including the panels) into the box.

CNCU15
Done. I’ve covered the air intake with a mesh to keep most of the dust out.

CNCU16
I engraved X, Y and Z in the fibre glass panel to keep track of which contact is for which motor.

CNCU17
I’ve covered the air inlet with a mesh to keep most of the dust out.

CNCU7
Before now, the stepper-motor wires were in danger of getting caught during operation. To eliminate this problem I used black a black PVC tube normally used to run electrical wires inside walls in houses.

CNCU8
The tube is nice and stiff and will keep the wires out of harms way.

CNCU9
A small black box on the side to hide the wires.

CNCU11
Soldering the connectors.

CNCU12
The wiring done! Tidy.

CNCU13
Machine almost done.

CNCU14
Wiring protected and tucked away.

CNCU18
Ready for the next cutting mission.

CNCU19
The controller box all hooked up.

CNCU20
Time to cut some more stuff. Now without having to worry about the wires catching while cutting or something getting into the motor controller and damaging it.

  1. Hi,
    I have really enjoyed reading many your posted projects, and this one is way cool. I didn’t know that there are hobby style CNC machines. Wish I could find one for myself, but wouldn’t know how to set one up or what all is in involved or need.
    But many thanks for all that you have contributed to the Rc community!!
    Ps I built a tri copter because of you. I have been in the hobby off and on for the last 30 plus years and not a big fan of helicopters, but like the muti-rotor stuff. Your statement that you have tried many thing but always return to the tricopter is what inspired me.
    Many thanks
