General Mach Discussion / Re: treadmill motor for spindle

« on: May 31, 2019, 05:47:57 PM »

I used the treadmill's speed control and wired it to a toggle so that it could be used both manually and through the gecko g540.  Nice for CSS with mach4

I recently replaced my sieg lathe motor and controller with a 2.5 HP treadmill motor and the mc60 controller that was in the treadmill.  This allowed me to remove the h-low gearing.  Used a 2:1 timing belt to achieve the low end torque I wanted.  Really like the result.

General Mach Discussion / Re: Lathe arcs G2 G3

That is the best write up I have seen anywhere for arcs on a lathe, thank you!  That along with one of those three points on a circle calculators and I think I have my answer.

General Mach Discussion / Lathe arcs G2 G3

« on: May 08, 2019, 11:18:48 AM »

Need a little help understanding G2/G3 on a lathe.

What I would like to do is create a series of ribs along some .75" stock.
.125 in length(Z) and .010 in height(X).

Suggestions as to how to calculate the radius or center of the arc?

TIA

Mach4 General Discussion / Loop Counter

« on: April 29, 2019, 01:43:32 PM »

When you run a subprogram (i.e. m98 p1234 L10) is there a register or other accessible variable that can be accessed to display the current loop number, the number of loops left and number of loops requested?

Mach4 General Discussion / Re: 3 position toggle button

« on: April 13, 2019, 12:15:19 PM »

My initial approach would be to use a regular button and on the LeftUp script I would check the label:
If scr.getProperty("MyBtnName","Label")=="ON" then
  scr.setProperty("MyBtnName","Label","OFF")
  set a register or send a signal and or change the background color or call a function
else If scr.getProperty("MyBtnName","Label")=="OFF" then
  scr.setProperty("MyBtnName","Label","AUTO")
  set a register or send a signal and or change the background color or call a function
else If scr.getProperty("MyBtnName","Label")=="AUTO" then
   scr.setProperty("MyBtnName","Label","ON")
  set a register or send a signal and or change the background color or call a function
end

Haven't done any LUA programming lately so you would have to check the above syntax for errors.

General Mach Discussion / Re: Mach3: Expose APIs from Mach4.Document

« on: April 10, 2019, 12:29:39 PM »

It's been many years since I developed my Mach3 COM wrapper.  I was using Delphi which is object pascal.

https://www.machsupport.com/forum/index.php?topic=32144.0

 I have attached another pascal file (renamed .txt for upload).  I think you could rewrite it to C++ fairly easily.

Seriously!!?? I looked at that graphic over and over and over and yet missed the Xi and Xf placement.  Sorry for being so dense.  thanks

Mach4 General Discussion / Turn Cycles - Taper

« on: March 13, 2019, 04:04:23 PM »

Trying to turn a morse 2 taper using the turn Cycles Taper Cycle.  I thought I could just enter .375 for Xi, .5 for Xf and  1.4307 for the angle and it would determine the z Distance.  I an't find any combination of buttons, purple square looks right but I get the "IDOD dimensions for X don't match" message.

Anyone know how this is supposed to be done using taper cycles?

Can't find any documentation.

TIA
