Hi DickB

I too have played with the simple two transistor circuits and could not get them working.
I am very interested is learning more about your microcontroller based impulse circuit.
From...

Hi Dave

Thanks for the info on the gear size. My machine is bigger enough to cut that size.

Thanks Zig.

Will give them a try later in the week.

I am in Adelaide.

Oops. Forgot the attachment

I am after some advice on depaneling PCBs.
I have some 2.55mm PCB milling bits (see attached photo) and would some information on their use.
I will be working with 1.5mm, 2.5mm and 3mm FR4...

Here is the design.
Notice that the top bearing is not pressed in the main body. It presses into the stator pack as per the Scorpion build instructions.

I was thinking of pressing the stator off...

You can even wind your own motor!

Hmmm. That's go me thinking. Buy the kit. Ditch the center bearing holder and make this part of...

The Aluminium that I am using is 50mm x 50mm x 6mm
Some 2" X 2"x 1/4" would work fine.

I haven't cut anything with it yet. I have drilled a couple of holes. I have my trim router mounted at the...

Hi Gingernut

Nice looking clock. Could you give us an idea of the size? Largest gear diameter?
What is the winding mechanism?
I only have a smallish CNC and am thing of buying your plans. I...

I am planing on using 608 bearings.
I went the super easy way today and mounted the ER11 collet chuck in the motor using the original bearings. This was easy to do but i am not sure if the life of...

My package arrived today. :)
1 x Turnigy 890KV motor
1 x HobbyKing 100A ESC

Tools? As eSilviu posted you can run the collet chuck in the original motor bearings. Just press (hammer) the...

Michael Hammer is the guy who cast and build the one in the rcgroups thread. The thread is all about the build of his router.
I took the easy way out and bought a 75mm diameter round extrusion 150mm...

In the process of building one of these.

Waiting for my motor and speed controller to arrive. Should have been here last week....

Hi Bob^

What run-out does you spindle have?

Hi Guys

I know a few people have purchases ball screw and bearing blocks from LMB on ebay.
I have an issue trying to pre load and remove the end float from my ball screws.
I have a dial...

Great work! Can't wait to see the video and the sound of 7000oz-in stepper motors.

Here is a nice small 5-axis machine. You could fit a dozen of these in this big monster. I think it is big enough...

Hi All

Get very close to locking this design in and start the parts order.
It will be fixed gantry with moving table in one axis (other will be across gantry)
Cutting area will be around 350mm x...

Great minds think alike (or both have bad ideas)
Looks very similar to the design i am just about to post and ask questions about.

Hi Guys

I am looking for a source of Aluminium T-slot style extrusions in Australia.
40mm x 40mm or 50mm x 50mm sizes.
I will try the agents for 80/20 but wanted to know if anyone else has come...

Thanks for the link Geoff

Looks like they are the go for what i need. Just need to work out how i need the ends machined.

Thanks

I am in the process of collecting all the parts for my first 'real' router.
Will be used for PCB router all the way up to parts for RC cars and helicopters.
I have a huge array of stepper motors...
