spindle encoder help

Right, so as I mentioned the encoder number is wrong.
(you dont need 3 encoders and if you create 3 encoders
you will still not have encoder number 3 ( just encoders 0,1,2 )

In your custom.hal, replace

loadrt encoder num_chan=3

with

loadrt encoder

The replace all instances of "encoder.3" with "encoder.0"
and you should be a lot closer.

Thank you PCW.
I tried that trick.
but no digits displa in the spindle speed dialogue but spindle at speed becomes green to red.
without inputting encoder to stepconf spindle speed dialogue in axis gui becomes 0 to 1 when i spndle CW

Spindle Enable
If you need a spindle enable signal, link your output pin to motion.spindle-on. To link these pins to a parallel port pin put something like the following in your .hal file, making sure you pick the pin that is connected to your control device.
net spindle-enable motion.spindle-on => parport.0.pin-14-out
4. Spindle Direction
If you have direction control of your spindle the HAL pins motion.spindle-forward and motion.spindle-reverse are controlled by M3 and M4. Spindle speed Sn must be set to a positive non-zero value for M3/M4 to turn on spindle motion.
To link these pins to a parallel port pin, put something like the following in your .hal file making sure you pick the pin that is connected to your control

device.
net spindle-fwd motion.spindle-forward => parport.0.pin-16-out
net spindle-rev motion.spindle-reverse => parport.0.pin-17-out


1) Linux cnc spindle configuration documentation says pin 14 as spindle enable to hal.
If i add net spindle-enable motion.spindle-on => parport.0.pin-14-out
What should be the hardware configuration.

2) As well as i am using a 5 axis chinese breakout board.use pin 17 as spindle cw.i hook up wire like this.

Pin 17 > bob relay normally open > auxiliary 5v coil (it connect to 230V contactor coil)

> it will run the 3 phase motor.


How can i run spindle ccw and i want to run both directions by on off by bob instead do it manually.

Any suggestions?

something wrong i have done?
can't i check my encoder if it working or not.
s their any solution?

Read the encoder position with halmeter
The encoder position (encoder.0.position)
should increase by 1.000 every spindle rotation
if your scaling (and wiring etc) is correct.

always 0 (encoder.0.position) when it rotation in hal meter

i connect pins like this

pin 10 to phase A
pin 11 to phase B
pin 12 to index
pc 5V to encoder 5V to 12VDC
pc gnd to encoder 0V (common)
GND(sheild) not connected

How are A and B connected? If you are using a standard 5 AXIS type
BOB, the BOB inputs are not 5V compatible AFAIK

i connect pin 10 to phase A
And pin 11 to phase B.
Is my bob not compatible for encoder input or bob 5V is not enough for encoder.
Or both matters for this probelem.

Nexr thing is 0V and gnd wires should connect together?

yes pin 10 and gnd have 12V voltage.
Bob is 5 axis chinese breakout board.$5 one when i bought from ebay.
