Can you attach a copy of your Gcode which exhibits the problem.

General Mach Discussion / Re: accuracy is off

Hi Mike,

You mentioned in post #5 that your outside diameter was not completely round (my out side dia. is supposed to be 12  1/2" well in Y axis its 12  1/2 but in X its 12  3/8"). Checking your Gcode indicates that Mach3 will be following a toolpath which will produce equal dimension in both the X and Y planes and this is confirmed by the Program Limits of +/- 6.3438 (shown in the toolpath screen).

It would appear that you have a mechanical issue with your machine (backlash or flex, etc) which is causing the inaccuracy in the machined dimensions.
Perhaps ensure that the cutter you are using is truly 'sharp' and possibly reduce the feed-rate or depth of cut to reduce the loading on your machine components.

Hope this helps,

Tweakie.

General Mach Discussion / Re: Mach 3 Controlling Co2 Laser

Hi Wes709,

The M3 / M4 commands are far too slow acting so the M10Px / M11Px commands were included within Mach3 (and the M63Px / M62Px within Mach4) specially for laser use.
This thread describes my exploits and may be of interest to you;   http://www.machsupport.com/forum/index.php/topic,12444.msg248511.html#msg248511

Although I have used Mach3 for laser reproducing photographic images for many years now, for me, the relatively new software Auggie seems to have taken over.

Hi Mike,

The attachment in post #7 is not good. You need to attach your actual Gcode file (it has the file extension .tap, .nc, .txt, etc.).

Hi Mike,

If you post (or send me) a copy of your problem Gcode I will run it here and see if I can find the problem.

FAQs / Re: Problem with mach3 while another program is in background

« on: June 08, 2018, 08:31:54 AM »

It is, in my opinion, a Mach3 issue.

Although it does the same job Mach4 is entirely different to Mach3 and there is perhaps no direct comparison between the two. I believe Mach4 will allow you to do eaactly as you have described in you earlier post without issue but it is not something that I have tried.

(Although I have and occasionally use Mach4 I still use Mach3 for all serious work).

Sorry not to show much sympathy but...

Over many years similar issues have been found and that is why the recommendation that Mach3 should be run on a dedicated PC with no other software running in the background has been made by Artsoft. OK, faster & higher spec. PC's nowadays allow liberties to be taken but why do it ?

All I can suggest is that you use a separate PC for your CAD work and transfer your Gcode files to and from your Mach3 PC by memory stick or network connection.

General Mach Discussion / Re: Save Z - Beginner - To many options - Simple but not for me

« on: June 08, 2018, 04:51:21 AM »

Why do I not get any replys. What am I been doing wrong.

Atleast give me a hint. Dont let me be a cliffhanger here.

Thanks

You are not doing anything wrong you just need to give it more time - many do not visit the forum on a daily basis and many, like me, just don't have a definitive answer.
