I am going to use THCUD component.

Before the actual installation of the machine, I need to test the performance. What pins are mandatory to connect (UP DOWN from sensor is obvious)? How to set the velocity to for testing?
 

Well I connected the sensor and up & down relay is working fine.

But I am stuck in connecting hal pins.

As per the thcud documentation, "thcud.z-pos-in" to be conncetd to "axis.z.motor-pos-cmd". But in halshow, no such pin exist.
There is "axis.z.pos-cmd" and "joint.2.motor-pos-cmd". Please suggest correct connection.

In addition kindly suggest the connection for "thcud.z-pos-out" and "thcud.z-fb-out"

Halfile & ini file attached.

Thanks in advance for any help.

THCUD is an old component and probably predates the release of Version 2.8 where joints were separated from axes. Use the axis.z.pos-cmd.

QTplasmac has rewritten the book about plasma in recent years. I doubt anybody is still using THCUD. 

This is an oxyfuel cutting machine.
AND
"thcad.z-pos-out" connection?
"thcad.z-fb-out" connection?
 

Hi,
It was mentioned that there is a special bit file for the 7i96S to use a second encoder channel if one wants to do ohmic sensing with a Thad2 and the 7i96S?
I looked at the ZIP file with all the support bit files but I a cannot decode the bit file names to tell me what to use? Anyone got some info please?
 

7i96s_dpl.bin is made for this kind of use

Peter I get an "invalid bit file header" error if I try to load that bin file.

You may need to update your copy of mesaflash.

I get:

My mesaflash is from Master branch. Can it be outdated?
My version is 3.4.0-pre1
 

Yes, that's pretty old:

peter@peter-HP-EliteDesk-800-G1-USDT:~/bitfiles$ mesaflash --version
Mesaflash version 3.4.8

Oh ok. Didn't realize that. We should ask the gents to put the latest in master at least.
Do I have to download and compile?

Yes, I would download and re-compile
 3.4.0 is about 2 years old

instructions at bottom of page:

github.com/LinuxCNC/mesaflash

That worked. Thanks Peter. I will just download and compile as a rule.

If you put a 2.4MΩ resistor in each leg it would give you 49:1
 and 1MΩ in each leg giving a 21:1 ratio.
i want to know how many resistor watts do you need.

2 of 1 Mohm resistors should do just fine, one on each leg. 2W type just to be safe.
