Hi,

This is the code

LOADING \4
IF\4=0THENEXIT
TIME ON;\4
\4={\4*60}
:LOOP
TIME ON;\55
\55={\55*60}
IF{\55-\4}<ITHENGOTO :LOOP
-----G4

I see in the book G04 L#

I try everything G04 L100,G4 L100,G4I100 but nothing works

I want to see the RPM from my spindle I have an encoder from 500
I try this but I see always strange values -0.59 It doesn't change
like 100,200,900 from my Galil card I can see he is reading this encoder


#50=1 'START MOTOR SPINDLE LEFT
LIGHT 4;ON
GETRPM 8;\550
DISPLAY5 \550
-----M3

where is this calculate \74
DISPLAY4 {f*(\73/100)}
DISPLAY5 {s*(\74/100)}
GO x;y;z;u;a;b;c

Thanks

The correct command is:
TIMER ON

What are the contents of your timer.fil?
Here is mine, giving spindle rpm and a current feedrate update:
~@~TIMER.FIL
GETRPM 3;\57 ISPLAY5 \57
DISPLAY4 {\273*f}

The logic that you wish to have the timer execute needs to be written within the timer.fil

-----G4


'display programmed spindle rpm

DISPLAY5 {s*(\74/100)}


'display spindle rpm from encoder

SPINDLERPM \550
DISPLAY5 \550
-----M3


\74 is calculated internally when set into parameter in CNCSETUP ~ Analog Controls ~ SPEED (variable) ~ \74


PM your .CBK file to review for CNCSETUP parameter settings.

n174k has your G4 code spot on.

It takes a bit of effort to get your spindle RPM readout working.

<I'm assuming you have spindle speed control on an aixs>First run TEST SPINDLE to get the three parameters to put in your startup.ini. I not with my manuals so I don't remember the exact names of these.

Then you have to set up your speed pot. Read on this, instructions vary by how you set this up and whether you have a phisical pot, an on screen slider, none, speed mulitplier etc.

Finally, your M3 and M4 code will have to include the SPINFORWARD command. <My M3 and M4 turns on different contacts to start spindle, then issue SPINFORWARD> I like to use TIMER.FIL to read the spindle rpm every second or so and then put the rpm on the display. Several ways to do this.
