Hi, I saw the demo's and am verry impressed, so I downloaded the trial version. I can go through the process as far as to start the scan but then I get an error message to the effect  "camera too far from the machine" can someone pint a finger at what I am doing wrong

Hi all, I am a nu-bee and whats probably worse, an older nu-bee, having worked a working lifetime with hand and machine tools in the woodworking industry I decided to build a cnc router as a retirement project,using tips and tricks gleaned from here and there and  I get the basics of G-code functions from books and  forums but I would like to know where I can find diagrams to explain the machine's actions of the more involved code i.e. I J K etc and how to apply them to various axis.  Someone once said that a picture tells a thousand words and I am a great believer in that, I have found a great little app for my smart phone called "Rays CNC codes" and have found it great with its little line drawings explaining in graphic terms how Mach interprets these codes, I would be very interested in a book with this sort of detail in greater detail or even better if your forum could explain them on-line.

Hi, join the club, I built a cheapo cnc router and added a fourth axis "A axis" and have been trying to find the same answer for some time now, that this makes me very interested, I have tried drawing the normal X Y profile in cambam and setting the stock thickness to the intended radius the Y axis is the intended diameter and offset by the radius and creating Gcode to profile the design the full thickness of the stock with fairly deep increment cuts. I loaded the Gcode into Mach3, set the zero for X axis start (0), Set the centre of the spindle for Y axis start (0) and set Z zero on the surface of the stock. If you are turning from square stock you must remember to set the Z clearance level higher than half the diagonal measurement of the stock. I used a standard half inch worktop cutter and manages to do a reasonable sweeping profile which polished up nicely with the old glass paper.
I must point out I am a complete novice and pensioner playing at this as a hobby but try this on timber as I know it works

Hi all,
I am relativley new to cnc I have installed the 2010 screenset and think its awsome, the auto zero functin is great, I am installing a lazer crosshair and have altered the M890 macro and all works fine but I thought that it would be even better if that macro moved the X & Y to the zero possition (crosshair possition) can someone suggest the additional line for the macro to do this
