CNC Conversion lots of Questions!
Garyrmck:
Hi Guys,
I will go with the solid column x2 - this is the second model I linked in to in my first post - though from an Australian supplier. The plans I referred to will also fit the XY axis, as both machines share the same table.
cheers

Very good Gary!
I think you will be much happier. Check out the second link I posted for a neat plan for the Z axis. It is along the idea of what I plan to do mine. Mine is current converted to a 2 axis machine.
When you get a chance, please post up an introduction post.

We take the KX1, which is the same size as the second machine linked in the first post, to shows and machine steel and stainless with no problem. This is running Mach3 and no expensive Galil board which probably cost the same as the machine.

Well im guessing he could, but it would prob. just be faster doing it manually with a file - part of running a cnc is to have faster turn around for many. Because most of us know that manual machining can take forever and be tedious as...#¤%# I find the Sieg machines lacking, both rigidity and spindle power. Same goes for the smaller Optimum machines and Grizzlys. - its why i went back to the Aciera instead of running the BF20 anyway.
This topic is kinda opinionated anyway. As that and you get 10 different answers based on each posters subjective experience. =)

Agree, as usual, with John Stevenson.
Use belt drive 1:2 to 1:3.
Never use an integrated multi-axis drive.
Use HTD 5/15 mm belts (or GT or T5).
Cheap drives like the 2M542 series work very well, and can do above 100 kHz.
(To 4Nm, nema 23 to 48 V DC. Just what you need.)
These are the minimax solution, about 45€ each.
If you need better, you are much better going onto servos.
AC brushless servos are 150€ each, and 290 for a full kit with everything.

That is for sure. It is like asking 10 people which car you should buy! :bugeye:
