Remap M6 with rackchange.NGC

Hello Dear Linuxcnc community.

Yet again I am stuck. When Executing M6 command after opening drawbar I get warning : Drawbar not open. I checket for function and my I/O are correct. (Tried using atc toggle)

I suspect it has something to do with this part of INI :

[ATC_PINS]
# motion.digital-out-NN pins
# Pin to trigger air blast at TS
CLEAN_TS = 00
# Pin to toogle drawbar, unclamp tool
ATC_OPEN = 01

# motion.digital-in-NN pins
# Spindle specific signals for checking the status of the drawbar and the tool
# Tool pin; low = tool status unknown; high = tool inserted
SENSOR_TOOL = 0
# Drawbar pin; low = closed; high = open
SENSOR_DRAWBAR = 1

I dont understand what PIN does number 1 represents by SENSOR DRAWBAR ?

In my io.hal inputs are like this :

# --- Jianken Spindle Sensor 1 ---
# Mapping sensor 1 in ATC spindle: signal high = tool clamped
net spindle_tool <= hm2_7i96.0.gpio.000.in
# ---DI-11 ---
# --- Jianken Spindle Sensor 2 ---
# Mapping sensor 2 in ATC spindle: signal high = draw bar down (ready to receive tool)
net spindle_drawbar <= hm2_7i96.0.gpio.001.in

So, stupid me, i also tried to put in PIN nr. 000 and 001 - doesnt work. Or is that no Input Pin what you define in INI

Thank you,

Best regards

I guess the sensor is broken. After opening the drawbar, the sensor has to switch off and it doesn't.
The logic probably checks a signal change during the tool change

Hello

;Check if Release was ok by watching pin to turn high (L3)
M66 P #<_ini[ATC_PINS]SENSOR_DRAWBAR> L0

Thats the part that checks value.

SENSOR_DRAWBAR is defined in INI.

I didnt find any info on what value should I put into: SENSOR_DRAWBAR

Sensor is working properly.

The only person who would know is the person who wrote your INI file. Where did it come from?

But, we can probably guess.

It appears that SENSOR_DRAWBAR needs to be the number of the G-code digital input that the drawbar sensor is connected to.

You have in the HAL and in the INI, but do you also have in the HAL?

Hello.

Thank you for showing me the way. Now i get it.
