Hi,

I have been caught by the CNC virus.
I am a super NOOB.

Today i found a memorex telex ATL robot. this thing is massive and i am allowed to strip it for my needs. I think i can make myself a nice CNC table.

I want a CNC engraver driller for 3MM aluminum front panels.
How do i start?

any tips advices on what would be a good frame for my 19 inch panels?
I allready read a lot but it is so diverse that i have no clue on what to take for my machine.

I have some electronics knowledge and little mechanics.

Soon i will post some pics of my stripped parts. I hope people than can tell me if i have scored ok ;)

If you are not doing any piercing of the front panels while engraving, then I would opt for some cast jig plate of 61 cm X 61 cm x 12 cm it is fairly flat somewhere in the vicinity .12 mm over 30 cm. You'll probably select a gantry setup...either move the gantry or move the table... You are on the right track....idea, design, implementation, modification, etc.

You mean by this the working area?
It sounds perfect!.

Thanks for your feedback.

Yes, that is the working area. Remember that for the bit to cover the total 19 inch panel area you must have some extra room on each side for the other half of the router or spindle mount to protrude when in the x and y axis....draw yourself a picture and you'll see what I mean.

I have a couple of pages on machines I've stripped, and a section on a small 3 axis mill...

Look at the Gantry Style router, I like his approach...

Well i screwed out the first motor. But i turned out BAD!!!

It says:

Super U
DC Servo motor
Type U1718-039EB8
12W 20V 3.2A 200RPM

SANYO DENKI co.ltd

A guess a servo is not a stepper so its usseless?

Well it can be used as a servo, if you end up with 3 then use the servo approach. But it definitely is not a stepper.

Will it make a huge diffrence if i would build a cnc router with it?

You can use either steppers or servos, what is initially important is the torque...once you get good then as Hu F.... says you get fast...when you go fast then servos are the way to go.
