Handwheel command and MPG

[precourt]

I have a hard time to setup a MPG on my retrofited machine.
The MPG is working, it is correctly connected on the auxiliary encoder
I want to use a rotary on screen knob .

[KNOB1]
VISIBLE=TRUE
TOP= 12005
LEFT= 140
POSTIONS=8
VARNUM=333
CAPTION1=Handle OFF
CAPTION2=Handle X
CAPTION3=Handle Y
CAPTION4=Handle Z
CAPTION5=
CAPTION6=
CAPTION7=
CAPTION8=
POSITIONS=4

I want to be able to get in an Handle mode
I use this logic for the handle button tryed the aproach via mcode
[BUTTON15]
VISIBLE=TRUE
TOP=7060
LEFT=6680
HEIGHT=500
WIDTH=500
FKEY= 0
CAPTION=
MFUNC1ST=93
MFUNC2ND=0
BITMAP=handle.bmp

Mcode
-----M93
IF\333>0THEN FEEDRATE 50:ACCEL 300000ECEL 300000:[HANDLE]

This macro

[[HANDLE]]

IF\333=1THEN HANDWHEEL 0
IF\333=2THEN HANDWHEEL 1;100
IF\333=3THEN HANDWHEEL 2;100
IF\333=4THEN HANDWHEEL 3;100

For me it has always been easy to deal with I/o using Inputio.fil
But responding in real time to a variable change in state seem a bit hard


In general I want the machine to behave as much as possible as a Fanuc control using mode JOG Handle and memory any help or example would be of great help.

Thanks

I'm not seeing your error on first look.

Add a whole bunch of MEASSAGE commands to trace problem.

MESSAGE start M93
MESSAGE \333

put at begginning of M93

MESSAGE handle macro

put at beginning of macro

see what you learn. The idea is to trace down problem to one or two lines.

Mind if I hijack your thread?

Don't set your sights too low. The machine should be better than a Fanuc control. One of the things needed to do this is an operator panel with all the functions your operator needs.

My current project is panel upgrade number two on my knee mill. I'm currently in the middle of wiring. See the attached pics.

Thanks for the reply, I already started to add two rotary knob one for function and one for 1X 10X 100X as on yours.

It s way easyer to deal with I/O and inputio.fil
I will send pictures of my machine on tuesday.

Have a look at the CONTROLL INTERFACE from cnc direct.

http://www.cncdirect.co.za/htm/cnc.html

Its a really easy way to make a controll panel with a lot of buttons.

Its a controll board whitch is connected between the pc keyboard and the pc.
You can add about 24 buttons and 4 rotary swtches.
You can simply add oem buttons in mach and program the keyboard strokes you programmed into the controll interface so yoyr buttons will work.

I have one of these and made a controll panel for my emco pcmill 50 with an mpg wheel. I can toggle all the axis, jog mode etc all with the buttons on my panel. even feedrate and spindle speed are contrlled trhough this interface.

Much simpler than programming buttons trough inputs..

You almost got it.

(1) You have a mistake setting the KNOB. You'll notice 2 POSITION settings. one for 4 and one for 8

(2) You have a mistake setting MFUNC2ND=0. You should also set this to 93 or else the button will only work half the time. You'll think you have a random problem.


(3) You may have another mistake but it may just be the way you have shown it here. The logic for the M93 should be entered above rather than below it.

(4) The Macro is using the basic settings and looks good. However to rotate through the axis the Hand wheel has to stop motion first and be reset to 0 before you job a different axis. At the top of your Macro add this logic commands:

HANDWHEEL 0

Dealing with or doing this with I/O is about the same effort. Once you understand all the choices available to you each method will give you more flexible. The virtual on screen knob method is best to use when you have a limited I/O number of relays to work with and don't feel like drilling a hole to mount a real knob.

With I/O it's this way in the INPUTIO.FIL file using example I/O numbers:

IF #20=1 THEN HANDWHEEL 0:HANDWHEEL 1;100
IF #21=1 THEN HANDWHEEL 0:HANDWHEEL 2;100
IF #22=1 THEN HANDWHEEL 0:HANDWHEEL 3;100

Whereas with a virtual knob its this way using example variable numbers:

[[HANDLE]]

HANDWHEEL 0
IF \333=2 THEN HANDWHEEL 1;100
IF \333=3 THEN HANDWHEEL 2;100
IF \333=4 THEN HANDWHEEL 3;100

Just remember to press your button showing the Handle.bmp to active it.
