General Mach Discussion / Re: Arc problem ?
« on: September 28, 2008, 03:34:57 PM »
Hi, 


Thanks for the reply.

Here is some of a similar code using 'R'

As you can see it is till doing the same thing with Sherline mode...grrr

Any other thoughts?

Thanks,

Andy

« on: September 28, 2008, 01:55:25 PM »

does anyone know why?

Thanks,

Andy

Hello,

I have been googleing around looking for a CNC lathe that can cut threads small threads 12.2mm external to about 6.4mm internally.  However the only one I can find is a Wabeco for around £7000.

I was hoping to have a #2 morse taper, a tool turret would be nice however I am guessing that it would be too pricey.  The main thing would be single phase supply.  I would consider paying around £2000

I don't know if I am asking for too much for too little money.

Any help would be appreciated,  I have time as my workshop will be finished (laying a new floor  :)) around December time.  Will look to buy then.

Thanks,

Andy

General Mach Discussion / Code window does not show all the code...
« on: September 17, 2008, 11:38:39 AM »
Hello,

After Generating some code in a cam program I then save the file as a Tap ->  load it into Mach 3 Turn.  -> the file works great untill the last 10 or 20 lines.

I am using the demo version and the code only has 160 lines.

Any help would be great.

Thanks,

Andy

LazyCam (Beta) / Can lazycam turn?
« on: August 14, 2008, 11:45:17 AM »
Can LazyCam import dfx to be turned?  I have watched the Milling video's however there is no instruction on how to turn.

I have not upgraded to a fully licenced version yet ( I intend to).

I have been watching the development of Lazy turn with interest but I dont think it is going to be ready for a while.

Can I use LazyCam instead? IF so are there any instructions on using it for turning?

Thanks,

Andy

Hi,

Thanks for this, and gives me somthnig to read, however I do learn better with code examples if any one has a simple one to offer.

Thanks,

Hello,

I am looking to Gcode a basic arc, however I have no idea where to start, I have written taper, and (thanks to Graham) doubble tapers so I suppose an arc is the next logical progression.  I know they use the I and K values however this is the limit of my knowledge.

If anyone has a straighfoward example they could share or code somthing up quickly that would be great.

I am useing a small sherline cnc lathe.

Cheers,

Andy

G-Code, CAD, and CAM discussions / Re: Double taper
« on: May 20, 2008, 03:32:28 PM »
Thanks, however I turned that to exact stop mode and it still turnes inward rather than out. :-[

Any other thoughts?

G-Code, CAD, and CAM discussions / Re: Double taper
« on: May 20, 2008, 01:44:21 PM »

Hi Guys,

Thanks for all the advice so far however below is my code:

How can I create an angle and control depth of cut, also when I run this it does not produce a double taper it produces an hour glass shape.  Is there any way to change this.  I am using a sherline lathe with the mach 3 sherline profile (metric).

Thaks for your support

Andy
