NC Pod / Re: Welcome To The NC Pod Development, Discussion and Support Topic

« on: January 17, 2007, 06:37:34 PM »

I have no idea how you have the time to do all the stuff that you do! It would be so fun to retro the Mill that you did and it looks like you are having a good time with the lathe too... and Here I am Stuck to the KB ;(

Someday indeed Brian LOL...   But truthfully just lately I have had what seems to be negative time!  The VMC has been running 8am - midnight most days of the week.  In fact just the other day I was still working at 2:30am, and took just the one day off over the christmas period.  But it was a big job I was never going to turn down...

But I do see some light there at the end of the tunnel, and the Hardinge will kick off again this month.  It needs to be anyway as the moment it's able to turn a real job I may be able to take a breather.

Lets hope oneday the POD will also be usable for lathes.

I have even considered a brand new VMC, but have decided maybe later!  50 grand is more than I can afford LOL...

Sorry for the large file size. but here is some video footage of my workshop machine running with Mach 3 and the NC Pod. The machine is Servo driven using MCG ID33003 Motors from Dan Mauch and our Tek10 TEKdrives. The spindle is a 2.2Kw 24,000 RPM AC Spindle Motor which is being driven with one of our inverters.

Thanks for showing the video, looks great.   I did get to see a Pod when Pete came visit me before christmas.   Certainly looks interesting to me, and so are the little deveopments Pete briefly discussed with me.

So you are getting 18m/min?  What motors, encoder count, reduction etc etc.

I wish I had time to play woth one, sometime soon I guess.

General Mach Discussion / Re: Has anyone seen this before?

« on: January 10, 2007, 05:19:16 PM »

You have to set Mach to wahtever your post processor is outputing.

The norm seems to be Incremetal IJ, Mach when in this mode will also accept R as Valid.

It might be you need to look at your post.

Wayne do you have a link that I can have a look at? Art and I have to get the delta tau stuff up and running but after that

Brian

Here's a link to the manufacturers page on it.

Roo got his HNC running on a Galil
Just got a video from him...

Damn all these people racing ahead of me. I'm going to have to play catch up this month!

I wonder why his machine thuds so much on axis reversal.  Maybe got severe acceleration settings.  Not what I'd like though. Hardinges are normally as smooth as silk.

I've got a ton of questions and will start asking as I digest what you've given me here. I appreciate your time!

Did you choke on it! 

Perhaps you could post some pics of your HXL up here.  Might help to identify any differences.

Wayne,
That looks like a nice card

Brian I got one reserved for me to play with when they are available.   Want to take a look at this option then?  Might just be a viable alternative to the Galil cards.

Your steps/inch will be 12700

635 x 4 = 2540 (Quadrature output of Encoder)

2540 x 5 = 12700 (5 tpi)

That will give you close to the figure I quoted above at 45Khz.

635 Although on 1st look seems pretty weird.   but if yo look at the numbers you end up with, it makes sense on an Imperial ballscrew machine.

12700 (12.7mm = 1/2") 25400 (25.4mm = 1")
