LazyCam (Beta) / Offsets on circles

« on: November 13, 2007, 09:05:21 PM »

[this pertains to LazyCam Pro 2.58]

Ok, I'm really confused here so I thought I'd throw this out there for you to help out. I've created a .500 diameter circle and would like to cut out the outside diameter,  hence the need for an offset. Now first I check the scale and indeed it is .500.

I'm going to use a .125 endmill so I load the tool in the offset screen/tab and choose "outside" in the dropdown box. I clck on "create offset". Now the offset line shows up and enlarges the black border, but when I click to check the scale, it only grew .125 in size. Since it's a diameter, shouldn't it have grown twice the cutter diameter since it has to go around the .500 diameter?

Something isn't right, and it might just be me! lol!

Your thoughts?

LazyCam (Beta) / Re: Lazycam 2.05 - DXF import and scaling issue

« on: November 13, 2007, 07:17:34 PM »

I'm actually running into this problem as well. I create a model in solidworks 2005 and then create a drawing from it and save it as a dxf. When I import it into LazyCam 2.58, it scales it to a larger size. For instance, a .500 diameter circle becomes a 1.000 circle. Can anyone shed a little light on this for me please?

I'm new here and just bought a taig with Mach 3 and will be a regular "fixture" around here, I'm sure, as I'm completely new to the CNC world.

Thanks in advance for any info-

Dave


EDIT: I figured out that solidworks was simply scaling the dxf 2:1 so all I had to do was change it to 1:1 before importing it.

Mach4 General Discussion / Re: New people welcome !! Come in here and introduce your self!

Just wanted to stop and introduce myself. My name is Dave and I'm extremely new to anything CNC based. I've been a manual machinist in a manual based prototyping shop for about 24 years now , and yes, I've been in the dark ages all this time and finally wanted to learn CNC on my own. Just bought a Taig micromill 3000 to get started and I'll be using Mach 3 with XP pro on a Dell D600 laptop.

I've already encountered my first worry though. I've read that the printer port on the laptop may not be enough voltage for the connection to the control box but I can't find any info through Dell to actually know the actual voltage that it has. If anyone has any info, it would surely be appreciated.

I look forward to being here and leaning from all of you and in time, hopefully I can contribute in some way.

Thanks in advance-

Dave
