G'day Greg
I'm in Toowoomba, but have not done any RC stuff.

Cheers
Wayne

Table Size (2400 x 1200) :)

Try using a fine tip, 15 degree @ 200mm per min and 18000 rpm. This works a treat. My machine has a floating head, gravity is the only thing that keeps it on the job, it works just great. Cheers Wayne

Try Suttons aluminium two flutes cutters work very well with air, little expensive. I have found mixing oil and air does not work too well.

G'day

I had a similar problem with Aluminium. I found my machine had too much flex.

Yep, there are properly not needed, but its my first time build from scratch. I like to know what's going on!

These are my machine specs
ESS with MB-02-V6 Bidirectional Breakout Boards (from Homann Designs)
3 x Leadshine HBS86 (8Amp Peak) Hybrid Servo Stepper Motor Drives with Encoder feedback.
4kW air...

Where should I put these filters?
On the meter inputs or VFD outputs?
Have you seen this problem before?

Cheers
Wayne

Thanks for the responses.
More details,
These DC meters are for the motor drives, X Y & Z. (From 3 unregulated power supplies)
Whether I connect the spindle motor or not, this occurs.
The VFD...

G'day all,

I had a chance to plug in my 4kw Huagyang VFD and spindle, however it plays havoc with my volt/amp gauge.

G'day Danny,

Mass is the biggest reason I'm running a spinning ballscrew nut. If I was to run servo motors there is virtually no rpm limit for the nut assembly. I don't think there is much of a ...

G'day Danny

What power are your servos? I keep forgetting that servos don't loose any power at high RPM.

G'day Danny,
Sorry to hijack your thread.
If you need speed, go for the 10mm pitch ballscrew. I'm yet to finish my X axis to work out my max RPM pushing the gantry weight.

Cheers
Wayne

Could please elaborate on trajectory planners.?

Cheers
Wayne

G'day Danny,
I have got my Y and Z axis working.

http://youtu.be/bOoCjS6bBpM

In my opinion, I think the most important speeds are at max cutting torque. In my case, I have approx 800...

G'day Danny

Just curious, why so fast?

Hi
I'm half though my build, and I am using with ballscrews and spinning nut assemblies (for my X and Y axis)
3 x Leadshine HBS86 (8Amp Peak) Hybrid Servo Stepper Motor Drives with Encoder...

Great Video!

And finished with this...in minutes.

I had did make a mistake, after drilling holes in the Y Axis for the ball-screw mounting, I had no way of fitted the ball-screw with out slotting one end.

So with the ball-screw...

The Z Axis plates were milled and drilled on Tom's Fanuc Machining Centre. A another nice machine.

193250 193252

After that the assembly was easy.

193260 193258 193262

It will be once I have finished, thanks. As with all my projects, it always take twice as long as planed.

Holes are now driller into the Y Axis supports and the Y gantry. I have tapped the Y...

I'm building the Y Axis supports from 250mm wide heavy walled C channel. After welding top and bottom plate on the supports, back on the planner to square up all the surfaces. I love this "Bulter"...

So I have mounted the Y Axis rails, not as painful as the X Axis as I machined a stop on one of the surfaces.

Next, two plates welded to the ends, then back on the planner to...

G'day TurnTex
How far away is your gantry from the proximity switch trigger Before it triggers.?

All depends on how rigid your make your machine.

Nice build, got some more photos.?

Yep, Aluminium would have been easier as well.

is growing!

At home now, busily painting.

I have mounted the rails on to the Y Gantry. This when a lot more easily than the X axis rails.
