##### 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

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
