General Mach Discussion / Re: Problem setting up an xy table onto a Lathe

« on: September 16, 2007, 09:46:17 AM »

Now I have seen the set up, the only real way is to clock the unit square to the axis.

Why!

I will tell you,  grooves will have tapered sides, threads will be at the wrong angle and parting off and drilling/reaming will be a tool smashing extravaganza.

You can program out tapers in faces and in diameters but coordinate rotation can not fix this. Lathes must move parallel and square to the spindle or you are in big trouble.

My solution would be :-

A little bit of accurate setting the first time and then fitting taper dowels. This will allow you to refit the unit at any time with the same accuracy.

If price is of no problem then :-

OneCNC or AlphaCAM

Can you post a picture of the set up and indicate where the error is, we may be able to think of a better solution with more detail.

Hi Wellbuiltcabs,

How oval, .001 or .250", how are the axis driven, ball screws, belt and pulley,

A little more detail would help us give you a realistic answer.

Hi Chris,

Glad to here you are getting something out of my long, hard struggle with the program  . OK 15 minutes 

It will still need some tweeking but the basics are there, let me know when you get the thing ready to run and I will guide you through any mods.

Hi Chris,

if you look in the macro code you will see "G04 P250" this is a 250 micro second delay if you have your general config set for micro seconds, you must have yours set to seconds, all you need to do is change the P250 to P.25

Its an odd one that the link is correct, but the! in the link seems to confuse the browser, cutting and pasting seems to work.

General Mach Discussion / Prox sensors - will these work with mach setup

« on: September 13, 2007, 02:34:14 PM »

Hi all,

my turn for some help,

I have 2 of these prox sensors

"http://www.ifmefector.com/ifmus/web/dsfs!IE5222.html"

What I want to know is how would I connect them up to my bob as homing sensors, the 2 wire setup is confusing me, 3 wires I can understand.
