Good Day Eh!

Hi Clive,

Thanks for the warm welcome.... My head is spinning with so many ideas that I am reading. I am really trying to introduce the students to CNC and CAD/CAM. Luckily I have a local company that has donated a lot of parts to the school ( ie. Linear bearing, rails,extruded aluminium etc.) Which has been a god send as there is no budget in the school for such projects. I am a Tech teacher with access to the machine shop so that helps a lot. If there is any builds that you could recommend to follow I do appreciate it.

Thanks Dale

Dale It would help if you set your goals out regarding size of machine and what is it you want it to cut. Cutting ali is a lot different than cutting mdf etc

Hi Clive,

Sage advice to start me off right ..... I want to be able to machine a wide range from ali to wood. Size to be in the 3' x 3' range. Being it is for school I need it to have multiple safety incorporated in it . We build robots for the FRC and this will be key to have for it. I than want to use it to teach the students CAD/CAM and G code.

Thanks Dale

Hi Dale, welcome to the forum from downunder, it sounds like you have a fun job!

FRC = FIRST Robotics Competition (FRC) is an international high school robotics competition. Each year, teams of high school students and mentors work during a six-week period to build game-playing robots that weigh up to 120 pounds (54 kg).

Hi, welcome to the forums. Are you intending to build the router? Or buy an existing router? What sort of budget do you have for the router?

Hi Desertboy!
Thanks for the warm welcome and great read on your build.The idea so far as I am working with a limited budget is to get stuff donated to the school. Than see if I have to purchase the ball screw, spindle and possible linear rail.
So far I have had some excellent support from local companies.The Z axis head is a complete " THK GL20N" which is way cool!I have posted some PICS of the parts so far.

Size 1000 x 1000 ( aprox.)
Cut aluminum, wood, lexan, light plate.
Linear slider rails ( have a lot donated already)
Spindle I was looking at was 3 HP water cooled.

Not sure on good source for the ball screws and what ratio to use??( 1605???)

Thanks Dale

You a bigger pikey than me lol ;) Looks like you off to a good start. I wish I hadn't used 1605 & 1604 ballscrews now I should have gone for 2010 for the 1m axis and 2510 for the 1.5m axis. I bought mine off ebay from Hong Kong, alixpress is also good place to look.

Unsure about decent Canadian stores for cnc but there must be loads.

I've found the only difficult part with the router is getting the rails to line up with the ballscrew mounts, although we shall see once I have the plates made if I got it right lol.

Hi Andy,
Thanks for the warm welcome from down under! Yes that is FRC and we went into it first year as a rookie team. We made it to the district finals and missed out by 2 points to go too worlds in St. Louis. Great first year! looking forward to building this project with the students and hearing all the great advice, ideas from all you folks on this site. If you have any thing that I should look at ,read ...please let me know.
Good day mate and talk soon!
Dale
