Re: TSDZ2 open source firmware only for KT-LCD3 (v0.19.0 / v.0.20.0beta1)

I haven't been on here for a long time. Good to see development continuing and that Mbrusa has fixed the motor overrun issue. Before the world went crazy, I intended to work on this further and publish my code.. but my priorities obviously changed. Here it is for reference, perhaps it is different t...

Thanks, it might be. I don't have any looseness or play, but perhaps more drag with the motor off than others from what I've been reading.

Re: New "TSDZ2 Torque Sensor Central Motor"

I've seen a few other TSDZ2's even rode alongside a few of them, one of them being a poster on this forum. Their units were built in 2016, and much quieter than ours. Nor is ours a fluke. As for the drag its quite minimal when pedaling. Turning the crank by hand you can feel some drag for sure, but...

Re: New "TSDZ2 Torque Sensor Central Motor"

Last time I used a plastic zip tie, like others shared before. I still use the heat transfer adhesive to connect the sensor to the motor surface and then input the zip tie around the motor that also keep the sensor in place. I need to put this information in the wiki. Thanks for the idea, I'd be in...

Re: New "TSDZ2 Torque Sensor Central Motor"

Has anyone here attached a temperature sensor using JB Weld? Did you simply glue the surfaces using that, or encase the whole sensor in it? Or for anyone else, have you found an adhesive that doesn't involve encasing the entire sensor?

Re: TSDZ2 mid drive and 850C and SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Has anyone ever had a motor blocked error triggered by a sudden emergency stop, is that possible?

Now that I think about this, it was most likely a problem with the display attributed to extreme heat as no error code was shown and the display itself didn't seem to function correctly.

I've made good progress with the motor overrun issue, the second video below is what I was previously experiencing in v0.19 and v0.20 initially had similar characteristics. Perhaps some motors are affected more than others, or maybe it just doesn't bother some people as much as me. But this is now a...

Re: TSDZ2 open source firmware only for KT-LCD3 (v0.19.0 / v.0.20.0beta1)

Did you see that Ackmaniac did something to take into account the cadence for less overrun Maybe have a look at that and see if its also worth incorporating I similarly modified his fork and was running that as my go-to version for a while and it helped a lot. However, I think I've diagnosed the ov...

Aside from all the discussion about torque sensor issues, has anyone ever experienced a faulty cadence sensor? Yes, see the FAQ: Thanks, now I remember seeing that a while back. I've think I've narrowed the overrun cause down to the cadence sensor. Besides physical damage, are the sensors very resp...

I tested out eMTB mode and basic Cadence mode this afternoon. eMTB seemed good for its purpose, but for general riding I preferred Torque mode. eMTB pulls hard from a standing start but then is more effort to maintain speed because the assist varies quickly with minor differences in pedal input.

Re: Tsdz2 firmware open source adapted to vlcd5

Actually I rechecked this today and I need to correct that. At 35-40 kph at moderate cadence and assist I get more like one full rotation. Yours looks more than that.
