Simucube 1 help regarding fault 0's

Hi all, I need some assistance in regards to my Simucube 1.

I’ll start with some quick context, I bought this second hand a year ago and have been loving it. Recently it’s been giving me some problems along the lines of fault ID’s 140407, 440205 and 192001. All at different times depending on my startup.

My Granity shows:

I’ve been reading through the forums and have been fixing some things. Most of the faults seem to be typically made by the estop.

I’ve replaced the estop button 3 times, I’ve replaced the cable twice, I’ve replaced the RCA plug twice. In addition I’ve replaced the actual RCA connector on the box. After that I thought it might be EMI so I replaced the power plug with the EMI filter on it as it was rusty, but still no luck.

The interesting thing though is, every time I replace something and start it up, the sim works. For example, on Wednesday it wasn’t working, I replaced the RCA plug for the estop, it worked the entire time without a hickup, and the race was 51 laps, so about an hour 30 worth of time, but every time I turn it off, and turn it back on the next day, this issue happens.

I thought it might be software related, so I’ve deleted and reinstalled simucube and granity again, but no luck. I haven’t tried going to a earlier version though.

Looking for some guidance.

I’ve definitely ruined something somewhere. The only thing I haven’t tried is bridging the estop on the board and seeing if I could bypass it but would ideally like to avoid that if possible. I also don’t have any measurings of the board as I don’t have the tools to measure power but can find someone to do it.

Any help would be much appreciated.

Your settings in Granity seem to be very very basic and might not always initialize the system.

For small mige, MMC of 12.86 A and MCC of e.g. 8.0A should be used, and the overcurrent tolerance should be at Maximum for Simucube use.

However, all the fault codes you list, could be related to E-stop button itself, EMI on its wiring, or a regulator / circuitry fault on IONI.

It appears it’s the wire or pins for the encoder.

I took out all the wires on the sim and reseated everything, and weirdly enough it worked briefly. Then it stopped with the same codes, for some weird reason I turned to the wheelbase, and after releasing and reseating the clamps on the actual wheelbase it worked, albeit I got a over vaultage error after a bit of use. So I put in the settings you mentioned and also I found the fault tolerances weren’t ±2. After that it worked no issues what so ever.

I’m on day 2 now of turning it off/on again and it’s initializing and working like a charm.

When I get some time next, I’ll take off the cap and make sure there isn’t a bent pin for the encoder. I have a sneaky suspicion that might be it, but haven’t confirmed.
