HI

Its been a long time since I posted here, but my machine is running pretty good now for the last 6 months, only cosmetic things left.

Will the result improve the further apart the pulleys are placed? in other words, as close to the linear guides as possible?

Cory

Joe; Would this have absolutely the same effect as the other setup early in the thread?

This sure would make installation a lot easier

I am lurking around the net looking for info on collets/drawbars/quick chucks and so on to see if it is possible to make an ATC on my DIY machine.

I think the z should be sturdy enough, it doesnt show on the picture, but the 16 mm alu piece that you se passing through the cat track is going to a 20 mm THK liear rail suited on the top of the...

Hi

PaulC: here are some photos of the Z axis

There is no difference if i make a deep or a shallow cut.

Hi Glider

Ive tried all kind of acc settings from 150 mm/m to 1000, it hets a little better at 150 mm/m, but not much

I am going to try and put a large stepper motor on the x axis tonight and...

I´m running a Pentium4 2,5Ghz with 1Gb of Ram, so most likely this should not be the problem

Hi guys

I Have now lowered the gantry, and made a frame underneath, but sorry to say that i still have problems with deflection.

Good to hear that your vacum bed turned out great.

Its kinda hard to measure on the circle, but I would say close to 1 mm

I dissambled the carriers again and found dents in the carrier groove...

Great, is it possible for you to shoot some video of it?

What do u use for vacum?
Does the vacum loose its effect when you have cut some parts and made leakage?


Well its kinda hard to say,...

Looking around in the garage i found some 20 mm predrilled hardened steel rods with matching wheels.

Half of the weels have an offset center for making adjustments, Could this be something to...

I think I may have found the problem, I am almost suere that it comes from bad carriers on the linear rail.

Whwn I try to move them across the rail i feel some small resistance, like I can feel...

Thanx Dave,

Hopefully, it will be as accurate as I want it, I am also thinking of making a low vacum bed for my 4" balsa sheets when starting to cut some wing ribs, and one for my depron sheets...
