Damaged jrk?

One of my pots seized last week which resulted in the lever jamming itself against the gearbox housing. I replaced the pot yesterday but when I try to calibrate it I can't get it to determine the motor direction. Each time I try it instructs me to centre the lever. I have tried 2 other pots and checked the wires for damage without finding anything. I can run the motor from the jrk setup screen but it spins back and forward as it obviously doesn't know where it is.

Would the jammed lever have caused damage to the jrk? I can't see anything visually on the card. Any advice would be appreciated.

I did it 3 or 4 times just to make sure.

Only the min and max positions, all the other settings I haven't touched. I will redo the entire setup tonight to see if it fixes the problem.

I have reset all the settings, PID settings had been cleared but the motor still won't detect direction. I suspect I have a faulty jrk, when I first set it up I had the same issue. It just disappeared after I fiddled with wires and pots so at the time I assumed I had fixed a poor connection. Having checked everything thoroughly now I know everything is connected and working okay.

I ordered 2 more jrks today to add traction loss and heave to the rig so will try one of the new cards when they get here. I hope it isn't the card as they aren't cheap but if it isn't I don't have a working rig.

I can only assume it is the same type of pot?
I know you said you haven't made any changes other than setting min and max but check the reverse motor direction and invert feedback direction tick boxes. I have been guilty of missing that myself...

@Robdog , where did you buy the JRKS from?
Have you contacted the supplier to ask?

CHECK THE Reverse Motor Direction, I Also got caught by that one day when screwing around, Fiddled with it for quite a while before Robbie suggested i check the reverse box, SURE AS SHI* i must have accidentally clicked it.

Thanks for all the replies.

To confirm I replaced the pot with the same model
I reset the defaults using the option under file menu
Only error message on the jrk is no power as below. This confuses me as if I click run motor it does.
the motor reverse option is not ticked

In the INPUT tab, theres a box in bottom right hand corner "automatically set target", tick that box, then apply settings and try run motor

Have you got your motors installed the same way around, physically? If so, one motor direction may need to be reversed.
The other thing to keep in mind when setting the limits is, that on one side, the top limit may be the forward (max) direction of the motor where the other is the reverse (min) direction.
On my rig the right hand side has it's max on the top and the left has it's max on the bottom. I have one motor direction reversed and both feedback directions not reversed.
But without knowing your setup I can't say for sure that this is the correct setting. Just another thing you should consider.

After replacing all components and wires I discovered the problem was the motor itself. I don't understand electronics at all so was somewhat surprised the motor was the culprit as it still works. When connected up the JRK is unable to determine its position so I can't calibrate it correctly. Anyway glad it wasn't the JRK as they are far more expensive.

So you got it all working?
What kind of motors do you have? Sorry, but you got me confused with your last post.

Yes, all working now.

The issue I had was I could stop and start the motor using the command on the JRK configuration screen so the motor was still working. However the JRK could not determine the motors position so I couldn't calibrate it. As soon as I replaced the motor everything worked as normal so the original motors appears to have been interfering with the sensor.
