EMA Posted November 7, 2022 Share Posted November 7, 2022 1 hour ago, Rawnei said: Thanks for your input everyone. So @Freestyler analyzed the difference between v1 and v2 firmwares and found a discrepancy in the PID settings between them, here's a video demonstrating PID: So with this knowledge @Freestyler made a test version for me to test on my V2 that has the same PID values from the V1 before they were changed, I went on the first test ride just now and the difference was very obvious to me, I'm now actually enjoying the wheel! It still has a little bit of slack but it feels mechanical in nature and probably something that I can fine tune now with the bushing screws for better results but already it's such an improvement and much more enjoyable to ride than before. So @Pål Hammar Rognøy looks like we weren't insane after all. 😅 My first ride wasn't so extreme, I topped 54kmh at some point but rode pretty chill overall, did some uneven terrain, seated riding, very small skatepark jumps and stairs, things that needs to be tested further just to rule out the risk of oscillations with these settings: hard accelerations, hard braking, sustained 60kmh speeds, I will test that on the next ride. finally Quote Link to comment Share on other sites More sharing options...
Mango Posted November 7, 2022 Share Posted November 7, 2022 5 hours ago, Rawnei said: I would like to ask a favor of current Master owners to find more information and possibly identify the root cause regarding the play/slack/deadzone that some of us experience. If you own a Master could you check your firmware version by connecting to it using EUC Dash: https://freestyl3r.github.io/euc-dash/begode.html and report if you experience slack/play in the middle of your wheel or no slack/play, with this data @Freestyler can compare some values and see if we can find a root cause in software. For example I will start with my own wheel: Firmware Version: 2014902 Slack: Yes Doesn't appear the link works for me on iPhone/Mac. The slop/play is particularly egregious on mine. If the root cause is firmware related... rejoice! I can start thinking about doing pad and suspension upgrades but have been holding off because this.

Before resorting to FW upgrades to fix the problem, make the hardware adjustments first. On page 79 you find more info on adjusting the sliders. Some riders tell they could fix all play by adjusting the sliders. 1 Quote Link to comment Share on other sites More sharing options...

I only use this one. Anyway. Topic Master. As my rebound adjustment do not work, I made a 3d print to dampen the top out klonk. Printed is TPU. I am still trying different infill percent. 20% is to soft and weak. Feel free to try if you have rebound issues.https://www.thingiverse.com/thing:5596640 There is not much for the Begode Master on Thingiverse. Are there any other 3D print platforms with more stuff for the Master? Since you're sticking with the Master as your only wheel I strongly suggest you invest in the Kuba links and a Rockshox shock whenever you can, it will be a nice upgrade for you. 1 Quote Link to comment Share on other sites More sharing options...

Really annoying when riding slow off road. And it also makes a klicking sound when tipping forward and back when riding. Need to find out what’s causing this exactly as this is hampering my tire change. I’d like to eventually change to a different tire but afraid I’ll induce this play and that would ruin it for me. @iCafe since you have several Masters, have you experienced this pedal play issue and/or know the cause? Thanks. Quote Link to comment Share on other sites More sharing options...

It was Ok. There was not much communication on the order delays. However, the shipping estimate they gave was pretty accurate. I am currently in conversation with them about my Master not reporting motor current correctly. So far they have been very responsive. So overall It has been a positive experience. 1 Quote Link to comment Share on other sites More sharing options...
Garzal Posted November 7, 2022 Share Posted November 7, 2022 (edited) Was at a bike park today with my Master and it started doing a long beep short beep pattern over and over again. Turning it off and back on did not stop it. It is constant. I messaged alien rides and haven't heard from them yet. Anyone know what this code means? Edit: it still balances and rides fine though I haven't ridden it over a couple miles an hour since it started.

Per request: On 11/7/2022 at 4:48 AM, Mitch G said: Today I swapped my old 3500 mile kenda tire for a new shinko 241. The Shinko was a direct fit and didnt require any spacers or shaving to make it fit. Out of the CST, Kenda and Shinko 241, The shinko 241 is my favorite. On the street, the CST wants to fall into corners, the Shinko is more neutral handling and my old worn out Kenda didnt want to lean into corners and instead stayed upright and required the rider to hang off the side of the wheel to force it to turn much like street tires handle. The shinko leans into corners like most knobby tires and then just hold that lean angle. IMO a new kenda and a new Shinko would handle similar on the street but they all start to handle like a street tire after you wear the knobs down. The Shinko is also much quieter than my Kenda and CST but that may just be due to soft new rubber on the Shinko compared to my worn out Kenda. Off road, the shinko has the best grip out of the 3. IMO this is because the grooves are wider on the Shinko compared to the CST and Kenda. I am able to corner much faster and with more lean angle on my local trail with the Shinko installed compared to the old Kenda which is mostly due to age on the Kenda but I believe the Shinko would still have more grip than a new Kenda. Id like to see how the shinko 244 handles but the size of the huge knobs on that tire just seem excessive for our use IMO. Turns out I put an old Shinko SR244 on this Master. I was going to put a round street tire on it but the tire changed so easy and I just so happened to have the SR244 from a few years ago that I had put onto my MSX100V for a short time. Back then it felt like too much friction before I figured out the better side-knob-shaving with the SR241 that's on my MSX100V to this day (1000 miles later). 2 1 Quote Link to comment Share on other sites More sharing options...

RolluS Posted November 9, 2022 Share Posted November 9, 2022 I've sorted out by upgrading firmware. Downgrade and beeps are back. But... After dismantling the wheel and with motor câbles still connected (wheel on the side, be careful to not launch the motor while dismantled), no beeps on old version. It might be the hall sensor failure detection routine as per investigated by @Freestyler Quote Link to comment Share on other sites More sharing options...

Either it misreported a hall sensor error when it shouldn't or there is indeed a hall sensor error and they masked it. Although I don't think a hall sensor can partially work. It either works or it doesn't. Only Begode can now for sure, so I would definitely bring it on with them! 1 hour ago, Aztek said: Do you have issues connecting through this web tool?

Cerbera Posted November 9, 2022 Share Posted November 9, 2022 (edited) Quick question - what spec inner tube should I be looking at for the master ? I can't find any that are 20 x 2.75 (or 20 x 3.0) which is what I thought we needed... I suspect I might be wrong. presumably it will tell me when I get mine out, but my tyre irons are taking ages to get here, so won't be changing tyres til next week, and want a spare inner tube in case I kill one.

Cerbera Posted November 9, 2022 Share Posted November 9, 2022 OK, let me try and understand the weird syntax here: - that's 2 variations of essentially the same thing, right ? If the large number is first that is referring to the outer diameter of the wheel, and if it is last it is the inner diameter ? Confusing as hell that the actual diameter of the wheel, 20'' isn't mentioned at all in the inner tubes apparently for it ! I'll trust you and try and find one of those specs in the UK...
