    New "TSDZ2 Torque Sensor Central Motor"

    Yes, it is off. After like 10 tries I was able to install stock firmware. Whenever I get the error I just unplug and plug to other usb port and try again and keept doing that until it wrote program memory and looks like the bike is working fine with stock firmware. Would be nice to get OSF...

    New "TSDZ2 Torque Sensor Central Motor"

    I wanted to try out the settings you recommended and for some reason one time flashing worked fine but after that both JavaConfigurator and ST Visual Programmer can't write program data anymore I've tried putting stock firmware and looks like it's able to read everything and write DATA and...

    New "TSDZ2 Torque Sensor Central Motor"

    That's fine if the speed doesn't show up for a few minutes. But my main concern right now is that once I start pedaling motor is not engaged until a few seconds later. Once it start working it works fine but after a full stop it takes a few seconds again for it start working again. Never...

    New "TSDZ2 Torque Sensor Central Motor"

    I installed OSF on VLCD5 and just went out for a test drive and looks like I have another problem. Speed is not shown and E02 is blinking. When I turned off "Set parameters on startup" option in configurator, E02 is gone but speed is not working. I noticed that at the very beginning motor is not...

    New "TSDZ2 Torque Sensor Central Motor"

    Hello, I'm doing my second TSDZ2 build and once again I have a problem securing the motor to the frame. My bike has internally routed cables which come out at the bottom next to the bottom bracket. There's additional piece of aluminum welded at the bottom of down tube where the opening for...

    New "TSDZ2 Torque Sensor Central Motor"

    Thank you! Next time I'll disassemble the motor I'll try to clean connections and see if old motor still works!

    New "TSDZ2 Torque Sensor Central Motor"

    Hello, I've had lots of issues with my inner motor after disassembling it and applying thermal paste inside but eventually I made it work...for like 50km. I went for a longer ride and the motor was working fine while suddenly the power dropped and I've got E04 error on VLCD5 and I wasn't even...

    New "TSDZ2 Torque Sensor Central Motor"

    Good idea! It was worth a try. However, the problem persists. Stock firmware doesn't show E04 error but the motor stops working after biking for half a minute or so. :( I was thinking what else could be wrong... So back in the days when everything worked fine I noticed that there was a bit of...

    New "TSDZ2 Torque Sensor Central Motor"

    Yeah, I saw that too but my motor is 6 pin with no throttle function. No, I didn't do temp sensor mod. The only modification I did was heat dissipation "improvement" after which I started having all these problems.

    New "TSDZ2 Torque Sensor Central Motor"

    Can you please share some pics how it looks like? Yes, I can pedal easily with the motor off. There are no issues. And when it works after system start up I don't hear any strange noises and everything seems normal. I'm a bit reluctant to open it up again since I already nicely put everything...

    New "TSDZ2 Torque Sensor Central Motor"

    ...my story continued... So I was extremely happy that after two months I can finally ride my bike again so I went to test it out on a longer ride. I biked ~50km no problem until suddenly the power dropped and the screen started showing E04 error code on my VLCD5 display. After testing things...

    New "TSDZ2 Torque Sensor Central Motor"

    Hello, Just want to share an update on this. Few weeks ago I've got that weird sound problem described above. Tried many things and nothing worked. Recently finally received brass gear and put it in without any grease at all (just to test it out for like 100 meters) and the motor made the same...

    Tsdz2 firmware open source adapted to vlcd5, vlcd6 and xh18

    Hello, I just swapped my controller to the new one, installed 48V firmware and flashed OSF. Went for a test ride and everything worked fine for 50km and then motor turned off and is showing E04 error on the screen. What does this error mean? Sometimes it starts working for like half a minute and...

    New "TSDZ2 Torque Sensor Central Motor"

    The power drops and then the sound occurs. I wanted to do heat dissipation upgrade and removed the blue gear and the motor. When I removed the gear shaft on which blue gear mounts and put it into the little bearing on the motor there was a tiny bit of play. I don't think that this could be...

    New "TSDZ2 Torque Sensor Central Motor"

    Today I finally disassembled the roller clutch bearing. It was interesting to see how does it work inside. Also, I found that the rollers were quite greasy. Here are some pictures: https://imgur.com/a/gN1zkfd I soaked in degreaser my other blue gear overnight. Then used a screwdriver which fits...

    New "TSDZ2 Torque Sensor Central Motor"

    Yeah, I used the same Park Tool grease... So yesterday I soaked blue gear in biodegradable degreaser for a few hours, then used toothbrush trying to clean the inside and then put it under hot water, dried and used isopropyl alcohol to clean inside again and tried it in the motor. Unfortunately...

    New "TSDZ2 Torque Sensor Central Motor"

    Thanks, but I think that's not the case. When I assembled the right side of the motor I double checked it to be in place. Sounds similar but this video shows what happens when sprag clutch on the right side fails: https://youtu.be/PWlz4xw3pI8 And I just checked and mine doesn't slip like that...

    New "TSDZ2 Torque Sensor Central Motor"

    Yes, it happens in all gears, my chain line is good, the chain is brand new. Cranks rotate smoothly. Walk assist work fine without any weird sounds even when I'm on a bike. I've tried to connect electric motor without putting it into the housing and used walk assist and the spindle is spinning...

    New "TSDZ2 Torque Sensor Central Motor"

    Today I disassembled the right side of the motor so I can remove gear shaft. Then cleaned the shaft and inside the blue gear, put everything together, greased it (still don't have the right grease) and tried the motor again. No luck... Here's another video going slightly uphill and the sound is...

    New "TSDZ2 Torque Sensor Central Motor"

    So today I disassembled everything again. First, I've tried to replace blue gear back to the original one. The motor was behaving the same. Second, I disassembled the motor itself and checked if waved spacer was in its place and that white insulators were in proper position and were not...

    New "TSDZ2 Torque Sensor Central Motor"

    The spacer was quite bent but I think I put it in place. However, I didn't pay attention to white insulators when putting it together. Thank you for the ideas! I'll take everything apart today and will try to verify if everything is in place.

    New "TSDZ2 Torque Sensor Central Motor"

    No, I didn't install the temperature sensor. Thank you, I'll read the thread for grease recommendations and will try to source something locally! In the meanwhile would appreciate any other ideas what could be going on with that sound in the motor.

    New "TSDZ2 Torque Sensor Central Motor"

    Hello, Today, I've wanted to do heat dissipation improvement on my motor following tutorial on wiki, replace the blue gear, regrease everything and silicone seal the housing for extra waterproofness. Everything went quite well until I had to test it out... And the motor is not working properly...
