Quite impressed with it at the moment, very smooth and repeatable (set up a repeatability test).

 I’ll find a spot for it and bolt It down in the coming days and let her go flat out and see what we have  :biggrins:

I’ll let it run for a few hours non stop tomorrow and see if I get any errors.

Then I suspect an oil change would be necessary.

I’ll try to acquire an I/O card. (Will probably need your help with installing)

In the meantime I suppose I’ll just get to grips with programming it. Maybe teach a tcp.

Also, thanks for welcoming me to the forum. I’ve brushed over this site in the past but I never realized the wealth of knowledge here! And if everyone else is as willing and able to help as you are then it will be my first stop with any issues from now on! Hopefully I can help out a bit too. Now that this robots up and running I suspect I’ll have many more questions for you!!  :icon_smile:  :wallbash:

JLR from memory, when problems occurred, they usually swapped out the Arm or Controller rather than diagnose problems online....
Then it was usually taken to a maintenance bay to be investigated/repaired/re-greased and then ready as a standby unit......

There's plenty of experienced users who frequent the forum, and yes it is a wealth of knowledge for sure.
No worries with assisting with installing the IO......I think the procedure is in the troubleshooting manual in that link I gave you should you want to go it alone.......any probs, then drop us a post.....
I 'cut my teeth' on the C Controller, so it's nice to see the old girls come to life again......
Sounds like you'll be having some fun in the near future.......enjoy.. :n1:

Hi Kwakasaki,

I am now on my 3RD robot of the same model and controller.

Got the second one up and running no bother.

However, with this one, I am getting ERROR (-1424) Current feedback error of JT 3. Amp or Power harness error.

JT3 motor looks ok and I don't see any obvious damage to the harness.

I am going to try it with the controller to robot cables from the other robots to eliminate the cable as an issue.

Any advice other than that?

Thanks in advance!

Could be the motor for sure, but the current feedback is from the CT's inside the Power Block.
- Usually it is these that fail, or issues with the supply electronics within the Power Block.

If you have the same Controller for the Arm knocking around, swap the Power Block over and see if the error clears.......
