General Mach Discussion / Re: Xhc control card connecting to sangmutan bldc spindle control

Thanks for the kind words - that's the first thing I seem to have got right this week. 

Seriously though, I am pleased that you are on your way to getting everything working as it should.

Mach4 General Discussion / Re: Mach4 5-axis

« on: August 20, 2016, 07:39:35 AM »

I have also seen 5 axis, using Mach3, demonstrated in a number of YouTube video’s but, in my opinion, it has not yet been independently proven to be sound.

The way (as Steve has said) has, I think, been demonstrated by Richard in this thread; http://www.machsupport.com/forum/index.php/topic,32107.0.html

In the folder / file ;  C:\ Mach3 / macros / Mach3Mill / m4.m1s

Add the line   ActivateSignal(OUTPUT4)   or whatever Output#  you require – calling M4 will then activate the Output# defined in Spindle Setup and the Output# you have chosen here.

Obviously a similar procedure may be necessary for turning it off.

General Mach Discussion / Re: change of axis direction

If you change the direction low active state for any axis it will change it's direction of travel (assuming the axis does in fact move in both directions).

General Mach Discussion / Re: Mach 3 Display not showing G Code anymore

« on: August 19, 2016, 10:43:21 AM »

I know nothing of your Custom Piece but G90.1 will place Mach3 into Absolute mode when it comes to reproducing arcs.

Different CAD/CAM software may use one of two different methods for defining and producing the Gcode for arcs - some prefer Incremental whilst others prefer Absolute. If arcs are used within a Gcode file the appropriate G91.1 / G90.1 should always be specified but unfortunately, some post-processors do not do this and confusion is created within Mach3 (the common cause of the crop circles).

Any resources(books, links) you may provide for a novice on G code will be happily devoured.....

I have never read it but I understand that to learn Gcode this is the book to have “CNC Programming Handbook 3rd Edition” by Peter Smid.

I added G20 to the top of Code at the very first line and road runner disappeared.

The extents of the Roadrunner Gcode model are probably greater than your soft limits table size settings. Turn off soft limits and see if the display re-appears.

The Roadrunner Gcode file was created in Imperial (Inch) units and your machine is set-up in metric units so 1 inch of file shows as 1 mm on your display.
The Roadrunner file should have had G20 near the beginning to tell Mach3 that it was in Inch units but this was omitted (either by error or deliberately to teach us all more about Gcode  ) thus the problem.

If you add G20 to the beginning of your Roadrunner Gcode file then it should all work and display correctly.

FAQs / Re: NEED HELP Keeping Spindle ON, or Pausing/Resuming Routine

« on: August 19, 2016, 02:06:57 AM »

I fully understand what you wish to achieve and why but changing the work piece on a live machine with a running spindle is just not acceptable practice (it is perhaps better to waste part of your life waiting for a spindle to spin-up than spend the rest of your life with a possibly irreversible injury).

I think this is a brilliant idea and I wish you every success but if the project was to go ahead then the whole thing would need to be ‘Open Source’.

(If the full details of the “Mod Kit” are openly made available to everyone then it is fine. If however, the full details are only available to those who purchase the “Mod Kit” then you would be selling a product which is not necessarily related to Mach3 and it would not be appropriate to advertise here).

A different Section of the forum may be more appropriate but let’s see how much interest is shown.

Just my opinion.
