Hardinge turret encoder with wsum: 'Wsum.0.bit.0.in' does not exist

I am following along some tutorials and notes online about how to control a Hardinge Superslant turret in LinuxCNC.

As is, the code for my pins is the following I have some code in the HAL file that is the following:

What I am planning on doing is compare the result, raise the turret, rotate the turret, lower. I received the above turret code and have only modified it to my inputs. I receive a "'Wsum.0.bit.0.in' does not exist" in the debug. What am I doing wrong?

As well, does anyone else have code that could help? This is a Hardinge Superslant 3 axis with a 8 turret head and a 8 turret tailstock. I am floundering on this and progress is slow.

EDIT: This is in Custom.hal. Should this code be in Postgui.hal? When should code be in Custom vs Postgui? I have code to open and close the collet in custom.hal that I have been testing and running.

Where is the weighted_sum component loaded?

You would need something like this:

loadrt weighted_sum wsum_sizes=4

and

addf process_wsums servo-thread

Take a look at the "carousel" hal component. It already does all this.

(you have binary encoding)

Thank you for the info.

At this point I am still learning the formatting rules that are required. Simple rules that are obvious once done.

The above code I received in an email word-for-word and was trying it out. When I was reading I was following the info below to try to get it to work. I can now see how I have to write the lines you provided at the start.
