Wire it as shown but leave the AC relay out and follow the notes below the thcad. (as Phill says use ENCB)
Install the correct bit file
add this to your hal file (make sure the encoder.01 is numbered correctly)
# --- 7i76e ENCODER SETUP FOR OHMIC SENSING---
setp hm2_7i76e.0.encoder.01.scale -1
setp hm2_7i76e.0.encoder.01.counter-mode 1

Check to make sure
hm2_7i76e.0.encoder.01.velocity is showing some data in halshow. It should be hovering around your 0 volt frequency
Download ohmic3.comp from here and from the command prompt type
sudo halcompile --install ohmic3.comp
You may need to install the linuxcnc dev tools to do this.
If a RIP build, drop the sudo

Copy this to your config directory, edit the data as required for your version of the THCAD-5

File Attachment:

File Name: spaceship_...5-28.hal
File Size:1 KB


add this file to your ini file after your main config file
[HAL]
HALUI = halui
HALFILE = my_LinuxCNC_machine.hal
HALFILE = spaceship_ohmic.hal

You should be good to go!


I am waiting for my Z axis motor to come in but i tried to install the comp and it didnt work i tried both ways I see the that i have the linuxcnc-dev and follow it to src components and i see the ohmic.comp file.
Is there another way to install this?

if you type halcompile on the command line, is the program found?
If not, Try this and try it again.
sudo apt-get install linuxcnc-uspace-dev

It does not seem you have sorted out the buildbot commands discussed with Phill earlier in this thread. Linux does not know where to look for linuxcnc files.

Are you getting the latest version now when you run LinuxCNC?

Open Synaptic Package Manager, click Search at the top tight and enter linuxcnc as the search term. It should show all available linuxcnc packages.
