G-Code, CAD, and CAM discussions / Re: Radius to end of arc differs from radius to startline

« on: September 07, 2017, 05:41:29 AM »

Hi Mike,

Your .dxf is fine.

Your Gcode contains both Incremental and Absolute arcs (or at least variations on the Mach3 requirements for arcs).

My guess is that you need to look for a better / more up-to-date post processor to generate your Gcode with an arc format that Mach3 understands.

Thanks Rich.

For me CNC removes the need for artistic skills

Hola,

Carefully check your generated Gcode to make sure that it does have the G21 towards the beginning and that it does not contain a G20 further on in the code.

General Mach Discussion / Re: Mach3 is not talking to Breakout board

« on: September 06, 2017, 01:52:55 AM »

hi,
I hope someone can help me with my mach3... I've bought new breakout board and trying to connect with mach3, I already change the port address to my mach3 but when I load G-Code it not even move. how should I know that breakout board is connected to mach3?

Can you provide details (make, model, etc.) of your Breakout board and your CNC controller.

Also which PC operating system are you using ?

Hi Donnie,

With regard to the Gcode it is usual to use a CAD/CAM software (such as Vectric) where the desired part / item can be designed from scratch or imported as a DXF and drawn then, using it’s Post Processor, the Gcode is created then loaded into Mach3 for machining.

There is a very basic CAD/CAM in LazyCam (which comes free with the Mach3 download / install) – this can get you started but be prepared to purchase a more sophisticated package as you needs grow.

Hi Basil,

You perhaps need more details from the supplier of your controller regarding spindle control but my guess is that it is just manually operated.  

If your 4th axis (A axis) is connected and not Inhibited within Mach3 (Settings (Alt-6) page) then you should be able to control it’s rotation from the MDI (Alt-2) page.
For example Input…
F500
G0 A100
(Pressing Return after each entry).
The axis should now rotate 100 units.
The A axis has to be set-up with steps per unit Velocity and Acceleration in Motor Tuning like the other axis etc.

Hope this helps.

Good suggestion, so far we have managed with a 'Wanted' Ad in the 'Bargain Basement' section http://www.machsupport.com/forum/index.php/board,42.0.html but I am sure the forum could always be improved.

Hi Basil,

Config. / Ports and Pins / Input Signals / EStop - change the Active Low to a tick. That should reverse the operation to how it should be
