Mach3 and Smoothieboard

[dalo]

Hi,

This a continuation to my previous post...but since Mach3 seem to be quite serious Gcode controller I think it should probably get its own thread.

Did anyone tried sending Gcode using Mach3?

How should it be configured to work with smoothie?

I tried configuring it in order to try doing so but encountered couple of problems:

1. Couldn't find the USB port (both Pronterface and repetier found it as COM3)

2. In the Mach3 manual they say not to install the Parallel port driver during installation (if you intend to use the usb port), yet when opening the configuration tab that is what shows there as port #1.

3. When trying to set motor output pins Mach3 doesn't recognize the decimal point of the smoothieboard pins and so for example:

beta step pin 2.1 become 2 which is the same as alpha and gamma (2.0 become 2 and 2.2 become 2).

and the direction pins all are 0 instead of the 0.5; 0.11; 0.2 in the smoothie config file.

Thanks,

Hello,
Mach3 has it's own motion controller inside and sends output to pins on
parallel port.
It's not possible to integrate them as they are in this moment. It will
appear a new version of MAch but that's another thing.

It's quite easy to drive smoothie with Mach3 ... you don't use the parallel port though. You use the serial port like with pronterface and mach3 generates gcode. I haven't used mach3 in a couple years so don't remember the specifics of how to set it up ... Mach3's interface is pretty obnoxious. :P
