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

« on: August 19, 2016, 09:22:54 AM »

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.

G-Code, CAD, and CAM discussions / Re: Issues with Excessive CV Rounding

« on: August 18, 2016, 04:25:29 AM »

If you increase X and Y axis Acceleration even at the expense of Velocity (which may have to be reduced) then it will reduce corner rounding and overall you should notice little if any increase in job time. It is quite a delicate balancing act to get it just right but give it a try.

Mach4 General Discussion / Re: UC-100 and Mach4

« on: August 18, 2016, 02:16:56 AM »

Looks like the pmdx only supports 4 axis.  I need 5 axis support.

Perhaps take a look at the ESS http://warp9td.com/
That will work 5 axis with either Mach3 or Mach4.

General Mach Discussion / Re: Change direction of the work area

« on: August 16, 2016, 05:41:26 AM »

Absolutely nothing wrong with your English sir - it is just my opinion that the topic is controversial only because many people will have different views regarding the origin and home positions.

but if I change the Direction Active Low state in the Config. / Ports & Pins / Motor Outputs. it will be mirrored then?

If +X moves the cutter to the right of the workpiece and +Y moves the cutter to the rear of the workpiece then it will not be mirrored.

General Mach Discussion / Re: Need help with Mach3 and W xp compatibility(or maybe wrong signals to pins)

« on: August 16, 2016, 04:15:00 AM »

Please check that your PC meets the minimum requirements shown here; http://www.machsupport.com/software/mach3/

Whilst a few may have had some success with the TB6560 boards there are many who have had nothing but trouble.
Perhaps not what you want to hear but my advice, if you are serious about CNC and want a machine which performs well, is to look toward using a better quality controller and one where the manufacturer provides information, service and backup. One such option may be the Gecko G540 (or similar).

General Mach Discussion / Re: Change direction of the work area

« on: August 16, 2016, 03:55:53 AM »

I think you are going to get lots of differing views on this (perhaps controversial) topic.

Whilst the medium to upper range CAD/CAM software allows the home position (X0, Y0) to be in any corner (including centre) the basic CAD/CAM packages generally only allow the home position to be in the bottom left corner.

In my opinion, your machine should be set-up with X0, Y0 in the bottom left corner of the work-piece with +X moving the cutter to the right of the work and +Y moving the cutter to the rear of the work ( Axis direction can be changed by altering the Direction Active Low state in Config. / Ports & Pins / Motor Outputs ).

FAQs / Re: Motor Tuning / Re-install Mach3

« on: August 16, 2016, 01:57:14 AM »

Hi JR,

I guess something has gone wrong with your installation of Mach3.
Version .066 is probably not the best to be using (according to popular opinion) so I suggest you download version .062 then install that as administrator and see if that resolves the problem. Here is a direct link to the file ftp://ftp.machsupport.com/Mach3/Mach3Version3.043.062.exe

It should install directly over the top of your existing version but keep a safe copy of your license file (Mach1Lic.dat) and <your profile>.xml file just in case.
