Glad you got it sorted. 

Don't forget to post some pics of stuff you make, we all like lots of pics.

Could it be the 360 deg roll-over ?

Hi Nuvarian,

Welcome to the forum.

Could be that you are set up in metric units and the GCode is in imperial units or visa versa.
Check the GCode for G20 or G21 codes - this could be a clue.

Maybe a good idea to check earth continuity and correct polarity of live / neutral on that extension cable then

Hi Dan,

The fact that everything was working OK for so long but now it does not work indicates, to me, that something has changed.

Have you made any changes to your installation ?
Have the power company ripped out your earth stake ?
Etc. Etc.

Something has changed, think hard, what have you repaired ?

Sward,

Mach should be up and running before you switch on your machine. All sorts of nasty things could happen otherwise

Jeff,

Is it possible than in changing motherboards you have made an additional (or broken a previous) ground connection ?

G-Code, CAD, and CAM discussions / Re: Cad Software!!!

Hi Fred,

Not all CAD / CAM programs will import a .jpg raster drawing (which is what you have) and turn it into a vector drawing (which is what you need to put into LazyCam) but here are some, off the top of my head, which are free, you will have to Google to find the download sites.

G-Simple (I made my first CNC part using this)
CamBam (free version has some unresolved quirks but I have used this a lot in the past)
HeeksCad (still under development but improving all the time)
DraftSight (this has only recently been released and I have not tried it yet)

There is a free version of Google Sketchup which now has many plugins making it more than suitable for home CNC use. It will import many file formats allow re-design and even export GCode (the GCode is tailored for the PhlatPrinter so needs a little editing but is not too difficult to do).

I will take a look at you .jpg and see what needs to be done.

Hi Fred,

There are loads of free CAD /CAM programs you can use to get you started, unfortunately they never seem to be quite so good as the ones you have to pay for. 

What do you want to do ?

What sort of photo ?
