Try clicking the Regen. Toolpath button - this always seemed to work for me.

Hi Chris,

My guess is that your GCode is OK and that your Steps per Unit have been set incorrectly in Motor Tuning.

It is perhaps best to calculate the steps as per your equipment and Al's calculator can help http://www.machsupport.com/forum/index.php/topic,16315.0.html
Alternately, you could use the Mach3 Axis calibration feature (Settings page).

Hi Tony,

It would be best if you post your question as a new topic in the General section where it will get more attention and hopefully some suggestions towards resolving your problem (this area is just for introductions).

Hi Chris,

Not sure if this is any help to you or not…

I machine many circuit boards and often use different CAD/CAM software to create the layouts. As the problem of scale is always a possibility I now include in the layout an outside border, of known dimension, around the pcb (or two outside markers of known distance).
Once the GCode has been loaded into Mach3 the Toolpath tab shows the Program Limits (size of my border or distance between markers) I then, if necessary, adjust the X and Y Scale DRO’s (main screen) to get the size correct (just a simple calculation required here).

Third party software and hardware support forums. / Re: Help and advising on breakout board / motion controller for my machine

« on: August 27, 2013, 02:40:54 AM »

My advice would be to start out simple (and cheap) with a basic PC (with parallel port) and a basic breakout board.

Once you have your machine up and running (having learnt about the way in which your motor controllers are connected, limit / home switches configured and Mach3 is setup etc.) you will know it’s full potential together with any possible limitations.
You then have a base to work from and can improve (perhaps at a cost) the areas that need improving.

(Although I have a Smooth Stepper motion controller, for 99.9% of the time I am still using the parallel port and basic PC running WinXP).

Maybe just watching the intro and advanced tutorial videos on brains may help you decide if they are suitable for your particular application http://www.machsupport.com/videos/

Thanks for the reply, it cleared up what I hope are the last of my lack of understanding as far as the basic set up goes.

I'm not certain we ever get a total understanding - I have been using Mach3 for many years now and to be honest, I still don't know the half of it.
