Hi all well I have managed to spend all of 2hours in my workshop this weekend.
A little while ago I posted here about a CNC machine I designed and built but it all stopped due to health issues.

Tho my health is still the same I had to get out of the house as I have been in here for nearly over 4monthes now and it really is doing my head in.

Any ways to the point :P I have managed to attach a cheap dremal to my CNC for proof of concept to see if it would do engraving and it worked ok seeing as there is a lot of play in the shaft and I used a drill bit.

When I get the money and im better I will invest in some thing better but for now its ok.

here is part of my pc case :)

the pen was for testing as I did not want to start running solid carbide bits at 1200rpm when I was a noob (still am)

OCUK and the forum members for the win :)
 
cheers for the info Jonny69 :).

Nice build there Hamzter I used 25mm linear rails high carbide steal :)

I will post a few pics of me CNC machine soon :)
 
Hi did I say 1200 yes your right I mean 12000.
Im stuck with a normal wood router so its hard to machine metal as its to fast if I get the feeds right its not to bad as that comps for the spindle rpm.

I have now got a small dremal on there to so its a little better for marching small stuff but the dremal is cheap so has a lot of play in the shaft but im skint like a lot of others and have to make do for now :P.

No there are no encoders as im using stepper motors not servos.
 
Thank you very much :) I will as and when i get out there keep you all updated :)

its about 0.002" deep i rubbed paint into groove then wiped off excess carefully ;)

Impressive :) Have a look through your software for a clearance figure, if your material is flat you only need a few mm above the surface for clearance, doing this will speed your jobs up as there is less movement required :)

?

0.020" clearance sounds good enough to me no time to be saved there.

you are talkin about rapid clearance yes if so then yes its as low as im gonna go 0.020".
 
Yeah its not bad a lot of people make them out of MDF I think because they have not got the option to use milling machines and lathes etc so wood is easy to cut and all so of course its much much cheaper wood is heheh.

I wanted to do it right from the start I may make a little wood one soon and sell it see how it goes wont be to hard really but it wont be for some time yet.
