General Mach Discussion / Re: DRO Axis Values (?)

« on: January 17, 2015, 03:16:52 AM »

Hi Leeawilson,

Perhaps check your MeshCam generated Gcode to make sure it does not contain a G20 code which would make the machine operate in Inch units instead of your desired mm units.
Motor tuning is in units so if Mach3 is set up for mm then that is what is displayed.

Hope this helps,

Hi Nate,

It beats me but I think you have ruled out everything but your machine electrical's and the tuning of your servo's.
Are all your voltages correct and being maintained during the run ? - Are all your electrical connectors truly sound ?

Running your Gcode, using a laser, the centreline of the toolpath produces a 1.2" square on the first pass and a 1.25" square on the second pass. Both the X-Y aligned square and the 45 deg. square are absolutely identical in dimension - there is no error.

So I think I can safely say there is absolutely nothing wrong with your Gcode or the Mach3 interpretation of that Gcode.

Hope this helps in finding your problem.

Thanks for the PDF link Terry - I have just learnt things I did not know about drilling acrylic.

And what type of dc motor are you intending to use ?

General Mach Discussion / Re: DDUM5 Breakout Board and fake licence

« on: January 15, 2015, 04:08:59 AM »

Hi  Toesponerse,

I have every sympathy with your predicament but I suggest you contact the supplier you purchased your DDUM5 board from to get the information you require.

It’s a tough decision as it appears you have a genuine Mach3 license but this forum is not really intended to provide backup support for the manufacturer’s of Chinese products which often supply pirated software as well as modified versions of Mach3 together with fake Mach3 licenses.

If it’s any help to the discussion I have just been and cut two 50mm squares, one on the X-Y axis and one at 45 deg. They were both cut ‘on the line’ with a laser so turned out 49.4mm x 49.4mm but they both measure identical.

Hi Ray,

Are you re-drawing the 45 deg. rotated square in CAD/CAM or are you using the Mach3 'Local System Rotate' function and the existing Gcode ??

General Mach Discussion / Re: Parallel port for PCI bus that works with Mach3 - just passing along info

« on: January 13, 2015, 07:48:11 AM »

I am only just beginning to get into the cnc scene. But, from what I gather about Mach 3 is that it is very feature rich for the price but it is picky. And, with me just getting into the hobby, Id like to stick to tried and true methods. Its only a cnc plasma table. I dont need top notch, nor all the bells and whistles. But, then again this is my first machine. Do you have a good resource for this ethernet smooth stepper topic, where I could read up on it? After all the trouble I just went through with Windows XP and the first parallel card Its sounds like a definate possibility in the future.
