Ive used the circular pocket wizard in Mach 3 a few times, it works well.
One thing to check, make sure the tool diameter you set is smaller enough to machine the shape you specify,

Hi, I'm wondering if anyone has made a scaled down DIY "Servobelt" drive that uses Nema 17 stepper motors???

I was trying to develop a DIY RPS (Roller Pinion System) so that I could make a large...

Hi Gerry, the pinion locations are quite precise, I drilled the holes on my CNC mill. The Cam followers press fit in quite nicely.

There is some noticeable backlash in this system.......

Hi Ian, I just hooked up some power earlier and tested the prototype.

After testing it for only 5 mins I can see signs of the aluminum wearing.
It is also much louder than I thought it would be....

Thanks for your comments Ian. I reckon your right about the aluminium ultimately resulting in backlash issues.
I was thinking the same thing.

If this prototype works then I'll definitely be...

Hi
I'm currently experimenting with a DIY RPS style linear drive system that eventually I plan to use on the x axis of a cnc router.

I also plan to scale the track profile down a little and use...

G'Day and welcome to cnczone

There are several types of linear drive systems that you could possibly use in a cnc machine, leadscrew, ballscrews, rack and pinion etc, they all have pros and cons...

Hi Daniel

I got a bit carried away, hope this is of some use.


The machine I'm building looks to be about the same size as yours.

I bought some stepper motors from Keling, 2 No. 270OZin...

I think you could use 1 (24v) 6amp power supply (shared between 3 boards.

Or you could use 3 (24v) 2amp power supplies (one for each board)

Just make sure you don't exceed the maximum voltage...

I used to work with a cnc router that had 3 routers side by side. I think it was a Reichenbacher (German machine).

It was only a small machine aprox 1m x 1m table.
If I remember correctly the...

Prboz,

The size of the stepper motors you need really depends on the size and design of your machine along with the size of the material your planning to cut.

If you reply with some of your...

Thanks for that Keyne

I think I'll just bite the bullet and fork out 299 GBP FOR THE 240V 50hz version next time I'm in the UK.

Just a bit annoying that the US version is so cheap.

Nikki

Thanks for you replies guys.

I've just been comparing the price of the GMF1400 UK version and its US equivalent
BOSCH 1617EVSPK, which appears to be the exact spec just set up for US a 60Hz US...

Hi Willy

I've recently started buying parts for a similar project, I got some second hand ball screws from ebay and some linear bearings and shafts from the following US website.

As you will prob end up buying Mach3 in the end I would try the demo of Mach2.

Here is a link so you can download the demo.

I've found it immpossible to find an american style cylinderical router for my machine over here in Australia so I'm considering buying a GMF1400 router from the UK since the UK and Auatralia both...

I think a lot of people tend to use mach3 and its good value for money.

If I understant correctly, Mach3 can be used to generate G-Code and to control your machine.

You can simply import dxf files into CAM software which you can visualize in a CAD type environment for example top, front bottom bacl left and right views. You can also import 3D wireframes however...

Hi Everyone

I'm new to this site, been following it for a while though.

I'm based in Moorabin, Melbourne.

I'm in the process of designing and building my first desktop CNC wood router approx...
