General Mach Discussion / Re: Modifying an old Mach3 macro to engrave sequential serial numbers

« on: June 19, 2017, 08:15:28 PM »

helmholtz,

May want to have a look at Page 18 of the Macro Programmers Reference Manual.

      STANDARD DRO'S    OEM DRO'S 
X DRO  0                 800
Y DRO  1                 801

Since the referenced macro in the mach tool box was posted in March 0f 2009 that "MAY" imply that use of dro code in Mach3 release 3.042.021 at the earliest. Only Terry would know more , but he retired from this site.

FWIW,

RICH

Don't recall a past  post on this and not sure what is causing it.
What version of Mach3 are you using?

The gcode is back plotted into CAD and I added the dimension to the drawing.

The lathe code as backplotted shows the pathing - see pic. The radius of the piece is .3126 ( close enough ).
Note the setup required in Mach3 lathe to run the code properly. Just run the code and note the X axis position as it goes through the
pathing in the graphics display.

Guess my memory is not as good as it used to be! 

RICH

BTW, Your using the mill to do lathe work and I am not up or done that.
Not sure what sceen set your using but think Calypso Ventures provides for
it in MSM.

If memory is correct I think the default for the mach 3 turning CPS file  is radius.
Not sure how your going about using Fusion 360, but I would suggest you use the lathe module ie; sketch  the part in the correct quadrant for the  tool post to be used ,do a revolve to create the solid, set things up correctly in CAM, and define the tool properly.
Simulate to confirm that pathing is appropriate.

May be wrong, but in general, sketch /cam/ post in radius and configure mach appropriately and all should be good.

BTW, attached file should help for defining the lathe tool insert in Fusion.

Have fun,

RICH

General Mach Discussion / Re: What does "G40.1"

« on: June 11, 2017, 02:52:54 PM »

In Mach4, G40.1 command is for Arc Type Cutter Compensation.
 
Other than that know nothing about it.

General Mach Discussion / Re: Mach3 Turn tool offsets just don't work

« on: June 11, 2017, 02:30:14 PM »

Luke,
Turn tool offsets do work. I need  to carefully read your post. There are a number of ways to do tool touch off and they all work.
BTW, I personally made a custom screen set and,  probe all the tools to populate the tool table, use the master tool concept, manipulate the table
via buttons if so desired etc.

Later,
RICH

MACH TOOL BOX / Re: Macro, Thread milling NPT thread, Inside/outside

« on: June 06, 2017, 05:56:18 PM »

You will need A CAD/CAM program to generate the code. Cambam, Fusion 360, there are others.
Enjoy the learning curve.

MACH TOOL BOX / Re: Macro, Thread milling NPT thread, Inside/outside

« on: June 06, 2017, 08:48:40 AM »

what's the 'resolution of thread' means?

Never tried or used the macro. Based on my poor programming skills, my"guess" is as follows:
The threads as straight line segments NOT arcs, so the resolution is how closely the length of many straight line paths  would be fitting inside / outside of 360 degrees of a diameter.

Setvar(18, question("Resolution of thread"))
Code"#10=[360 / #18]"  
Code"#109=#10"

RICH

I am sure Rich will be able to answer that question.

General Mach Discussion / Re: Question about lost steps and CPU cycles...

« on: May 30, 2017, 07:47:12 AM »

Adam,
You were given good advice by Gerry who is also a member on this site.

- Suggest you  dedicate a computer strictly for CNC and do not play around with it while running Mach.
- Make sure you have some headroom in the stepper tuning ie; velocity and acceleration settings
