The machine settings are stored within the 'Mach3Mill.xml' file (or whatever profile you are using .xml). The screen specific stuff is stored in '1024.set' (or whatever screen you are using) and the Macros folder contains any macro's you use. Also don't forget to save your license file (Mach1Lic.dat). That is the basic stuff but be cautious because you may have more Tormach specific files stored elsewhere so don't delete anything or make any changes you cannot reverse. (This is really the reason I suggested the additional HD you could install the latest version of Mach3, copy over the files mentioned above, then make any changes you choose).

Thanks for the complements relating to the laser project, I am hopeful more will follow.
I believe that one day everybody with a CNC will have a laser attached (probably fibre rather than CO2) but it is a bit slow catching on at the moment.

General Mach Discussion / Re: Optical Switch Not Recognized - How to Remedy?

Hi Gary,

My guess would be that the output from your 5 Volt conversion module is floating (with respect to GND) and that you need to provide a ground connection at your optical sensor.

A bit of lateral thinking here....

How about installing a second hard drive, copying the existing drive to the new drive, then you could boot to the new drive and change screens, settings etc without affecting or changing any settings within your existing setup. ??

Hi Roman,

First thing to check is that you have the Direction pin configured correctly in Config / Ports and Pins / Motor Outputs.

Hi Btboone,

On the Mach3 General Config page you can change your rotary axis setup from angular to linear by un-checking the appropriate box. In addition, by setting Rotation Diameter on the Settings page you can then adjust your Steps Per Unit in Motor Tuning to suit.

Hi Andre,

I am pleased that you are on your way. Don't forget to keep us posted with your progress.

Sounds to me like you do not have a PWM signal on that particular pin of else you have a conflict of pins.
If you attach your .xml file (Mach folder - the profile you are using - [usually Mach3Mill.xml] but it must be renamed to post - I suggest Andre.xml) I will take a look.

Hi Andre,

It's just a thought but are you able to adjust the laser intensity (set different current settings) from your GCode by using say S25 and S75 etc. ??

General Mach Discussion / Re: Decimal precision.

« on: September 01, 2012, 04:33:23 AM »

Thanks for your suggestion Larry.

I did actually resolve the issue by an extremely convolute process of recreating the .dxf from the GCode then recreating the toolpath to 3 decimal places.

There must be software, similar to Graham's Metric to Inch to Metric converter, which could do this task in a fraction of the time but I was unable to find anything suitable. Still, problem resolved now thanks again.
