Fanuc Serial Pulse Coders - Red cap servos, mesa 7i76e, how to?

Category: Driver Boards

I had red encoders on the two servos I was using but changed them for 1024 a b z encoders. They weren't compatible with the mesa card I bought- i thought they would be.  Was a lot simpler with standard encoders even with the startup positioning.

Can't succesfully release Tool (according to Probe Basic GUI)

Category: QtPyVCP

yes, that is the "spindle-released" sensor. As mentioned above I have to convert it to a binary value as the 14V is below the (60% of 24V) digital threshold of my 7i76e.

I can see the "spindle-released" going high when the drawbar is pulled (so, no error when releasing the tool) but get the error when clamping the tool.

Can't succesfully release Tool (according to Probe Basic GUI)

Category: QtPyVCP

Hi,

I am currently integrating my ATC. However, I get the Error "Failed to release Tool" message when I clamp the tool.

My HAL looks like the following. I get a 0-14V Signal which is converted into a HIGH LOW for the Motion controller.
#ATC Settings

net analog1 hm2_7i76e.0.7i76.0.0.analogin1

setp comp.0.in1 10.0
net analog1 comp.0.in0

net ventil-spindel hm2_7i76e.0.7i76.0.0.output-12 <= motion.digital-out-02

net spindel-released comp.0.out <= motion.digital-in-02

In the HAL Show, I can see that spindle-released goes high when I press the "Release tool" button in the GUI. I also do not get an error message. However, when I insert the tool and click "clamp tool" I get the message "Failed to release tool" although everything works fine (and the spindle-released goes back to low). 

I found that I need to connect the motion.digital-in-02 [url=https://github.com/dpslwk/probe_basic/tree/subroutine_unify_and_move_to_nc_files/linuxcnc/nc_files/probe_basic/atc_carousel]here on the PB Github (manual is hard to find). 
I was unable to find more information on the PB Website. The current PB Github also doesn't have this Readme file/instructions.

Does anyone know what needs to be done here?

Thanks![/url]
