Hi thanks for the reply - I actually found what I was doing wrong this morning. I was using the tool screen incorrectly.

thanks for taking the time to reply.

General Mach Discussion / MacTurn - Tool table setup for internal tools?

« on: May 25, 2016, 11:45:16 AM »

Hi, I have been trying to set up a few internal boring/threading tools for mach3.

Usually I set up my main tool using a led touch tool and then set up the other tools accordingly - easy.

But then I get to internal tools, setting the Z axis is the same - but how would I set the X axis as it is internal?

I thought of touching the back of the part and setting it to the negative of the front, but that then throws it all off as Mach3 then changes the offsets for the main tool. I need to be able to set the x axis of the second (internal tool) without changing the offset on the main tool?? (is that right).

Any help really appreciated

Seems to assume radius mode - when some people work in Diameter mode.

With all the crap going on with sourceforge injecting malware into downloads you may want to use a different repository.

Hello,

I just have released a beta version of my Mach3 Threading Helper. To actually cut a thread with Mach3 and the G76 macro, you need a couple of parameters, the numer of passes etc. For metrical threads, Mach3 comes with the G76_thread.exe. My application is far more sophisticated: i lets you select a thread from several standards or let you create your own size. The important feature is, that the tolerances are calculated given to standard and size, that it fits. Then you can simulate the cut - means you can try some number of passes to get the increment you need. Finally, the program generates the GCode which you can copy & paste in your file. So far, my threads had a perfect fit. And it's Open Source.

The supported Threading standards in version 0.10:

• M - Metric in medium (6g/6H) and fine tolerance (4g/4H)
• G - Withworth Pipe
• R/Rc - Tapered Withworth Pipe
• BSW & BSW Withworth
• UNC, UNF, UNEF
• M keg - tapered Metric

When supported, you can cut threads with multiple starts, too.

I've also made a throughly improvement of the G76, G77 and G78 macros and fixed the bugs there as far as possible.

The Sourceforge page:
www.sourceforge.net/p/mach3threadinghelper

Try it out and report if you find any bugs ...

I am using mach3 turn R3.043.063 and I don't have a m1076 to replace. Also can't make head nor tail of the program - can't get a simple M10x0.75mm thread working :-(

General Mach Discussion / G-Code line numbering/removing - quick and dirty app

« on: July 29, 2014, 10:02:18 AM »

OK, so being very new to Mach3, G-Code and CNC in general - in recent months I have been experimenting with different CAM applications, Mach3 wizards and generally editing G-Code.

I've found that the mixture of the Mach3 Wizards, Cambam and manual splicing of the G-Code seems to work well for my small needs. However being new to it all, I have found that line numbers in the g-code for mach3 help a lot for finding little bugs in said g-code invaluable. But then manually editing the g-code messes up the numbering etc

With this in mind I looked around for a g-code line number adding and removal tool - but couldn't find one that wasn't part of a £million suite 

So I knocked up a quick application in C# VS2013 .Net framework 4.5 (took 30 mins).

features:
1) Adds or removes line numbering in g-gode
2) It makes the changes in the text window only - until the SAVE button is pressed.
3) Ignores blank lines
4) Ignores comment lines - lines that start (.  e.g.   "( Toolchange )"
5) Supports .NC (cambam), .Tap and .txt files
6) Preloads numbers for formatting with zeros by counting how many lines are contained in the who g-code. e.g. if the g-code has 677 lines then that is 3 characters long. So the numbering would start "N001" to "N677". The two zeros are placed in the numbering to maintain formatting of the main code.
Example for 681 line code at start:

Code: [Select]

If the g-code was 10789 lines long the numbering would start N00001. Like I say simply down for formatting the g-code for myself for easy reading. When the g-code is bug free I remove the numbering.


Usage:
**** You will need the .Net framework 4.5 installed for this to work.
Unzip program, run, choose file, click add or remove line numbers - when happy click Save. If you don't click save the original file won't be changed.

Program reloads last .tap, .NC, .txt file automatically.


Quick and dirty:
This app doesn't use threading - didn't warrant the time being spent on it.
Minimum error checking - make sure the g-code file isn't in use in mach3 or other editor
Source code available if you want it - any bug just message me.

Disclaimer:
At your own risk  - blah blah blah - make backups of your g-code and don't moan to me if you lose a file.

Like I say I knocked it up for my use but you never know - someone might get some use out of it.

Cheers
Rim

Sorry been in Majorca for a week with the family. Boy it was hot! 35c in the shade one day!

I am using a spindle V4 board and it does exactly the same with the parallel port, a UC100 and a ESS (ethernet SS).

It sounds as though you don't have a sync signal coming back from the Lathe to mach, or maybe you just haven't enabled the sensing of it. Does threading work for you?

Cheers

That sort of doesn't make sense to me, if i didn't have the signal coming back from the lathe then I wouldn't know the actual rpm at all.

General Mach Discussion / Spindle speed crossover eliminating

« on: July 16, 2014, 05:26:57 PM »

Mach3 turn 062 .

I have the spindle setup on a spindle v4 card, all working good - however I have some speed crossover. E.g set the spindle at 300rpm and it will read 280, set to 1600 and it will read 1640, with a sweet spot of approx 800 rpm where s800 yields an actual speed of 800 rpm.

Is there any way or something I am missing to get the crossover lower or even eliminated?

Thanks
Rimmel
