Simulating with Millplus IT PC software, nerd level 1000

Simulating with Millplus IT PC-software, WinXP only

=>nerd-level 1000<=


There is a simulation/computer software for the millplus IT v530.

It use to be on the webpage when it was alive.

It's a freeware without saving capability. Ask, I may give it away.

so for the closest mourners, simulate millplus on a PC

A video of some demo I made few years back:

Use a virtual machine with winxp, install the millplus software.

Without a physical Dongle, no saving is permitted.

Theres possibility to sideload a CNC-program, and simulate it.

You can make your own program in ISO and IPP, but not save.

Use the overlay-file to see the machine-button-command.

Menu items are in the upper gray field click to open, but the are not clickeble in its own, use arrow keys on the keybord, enter to chose



You need to run the reference point before anything can be done, by clicking the ”all axis”-button.

Start cycle with CTRL+F8

Now the machine is ready to use.

Place a millplus compatibility CNC-program in the Work-folder,

Open the program in the same manner you do in the real machine

You may edit and program, but, no saving!


Running a simulation.


When you are in the machining view, chose your program to load it. tap the menu row, and move with arrow-key

You can run the CNC-program here, but the syncron graphic is zoomed out too much to make a good  use, more on this later

Go to the Menu-field, use arrows to go to graphics, point down to wire plot, enter

Now you can start the machining by use CTRL+F8 (CTRL+F7 to stop, F10 to clear)


You need too fix the zoom level if you don’t use G98/G99 after starting the machining the first time.

The scale is out of bounds, use the scale buttons to get a nicer zoom lever, note, Z is still out, havent figure it out yet

The 2nd time you run the machining it will be watchble.

You can use G98 and G99 to make a workpiece and run it in "full 3D" if needed.

Internal keyway in CNC lathe, programming help

 My post on internal key way was removed by blogger (google), check mail at the end

Broaching in CNC-lathe

 The simple way to make an internal slot in your CNC-lathe

You need to get or make the tool, it's not included.


An example of tools

Broaching tool

I read a lot of tutorials on how to broach slots, everyone is parametric, with R-values, and so on, and I thought, can you do this easy?.

My solution so far, the main program and a sub-program, some inc programming, and we're there


N10 G54


N30 WORKPIECE(,,,"PIPE",256,0,-35,-30,70,30)

N40 T="PLUNGE_CUTTER_3P" ;zero Z at center of tool

N50 G96 S10 M5 ;not the best "no rotation" command

N60 G94 F300 ;feed mm/min

N70 G0 X30 Z2 ;startpos

N80 KILSUB P10  ;subprogram, P=repetition times (how deep you go)

N90 G0 G53 X500 Z600 D0

N100 M30

and the sub:

N10 G54 ;just in case

N20 G91 X0.3 ;inc cut/sub run, aka cutting depth

N30 G90 ;abs prog

N40 G1 Z-20 ;depth in Z

N51 g0 Z2 ;return of tool

N60 m17 ;exit sub

Things that have a deep impact, the P-value is the cutting depth x how many repetitions needed.

something's not completely finished, never tried this for real, just couch-programming

now for the big techs small people bullying:
