Endless Sphere

heyDD- It sounds like a button or perhaps condensation problem that is causing phantom button pushes. In particular, holding the left button depressed on boot sends control directly to Setup - you primary symptom. Buttons not working is likely because one or more is stuck ON. Carefully unscrew the b...

i've got that bad boy installed now.

Here's what your posts in this thread look like on my mobile devices using Opera or Chrome.
Pretty much broken...

Okay - added some notes and a more detailed illustration above. There are precharge calculators on line if you happen to know the cap values in your controller...

What he said ^^^^^^ Here's a simple hookup that just uses a mix of one an two pin connectors. Easy with either Anderson PP or RC bullets. With a little heat shrink sleeving it just looks like a short Y on each side. QuickyNoSparkHookup.png 20-22ga is more than adequate for the precharge wire - the s...

But is there a benefit (for example in terms of torque) using a different kind of motor? What do I lose not using a hub motor (for example are rpms fixed in other types of motors?)? I originally proposed using the hubmotor because of the fabrication simplification and the ease of upgrade - just buy...

The grossy asymmetric Sempu waveform in combination with the high pole count has been found to cause certain CA 3.1+ PAS difficulties. This isn't directly related to the odd pulse timing your post illustrates, but it's another Sempu weirdness. This issue has been addressed and will be released very ...

...I am not so confident that motorcycle wheels would be reliable. Just a question of getting front wheels from a bigger motorcycle instead of a moped. Box the wheel with an outer strut to carry the other side of the stock motorcycle front axle and things get simpler. Likely needing brakes on the s...

Improved visibility has only do with knees, feet, and pedaling in that they provide points of visual complexity and change for others. Tying lighting to pedal motion misses the underlying cause of the Trek observation and suffers from the rate dependence you point out. If you want to get peoples att...

Red, green, black are the wires for the throttle White, blue, brown are for the 3 pos switch Red and white >= CA +5v Green and blue => ca line Brown and black >= ca gnd Red+white resistor green+blue ??? Green+blue resistor brown+black ??? I don't understand the references to resistors and the throt...

For other folks in a similar situation - who did those up for you?

I am trying to build an electric hand trailer capable to move 400-420 kg at a more or less constant speed of 3.2-3.6 km/h both on paved and unpaved road (though not a completely rough bumpy road). My main inspiration comes from the Carla Cargo trailer Chalo has lots of experience with pedicabs and ...

....with a KT36 20 Amps controller. - Do I really need dual torque arms ? Basically what neppy said above - two would be the best situation... But - regardless of voltage, your 20A controller is probably only going to provide 50 phase amps which is not really driving the Mac hard so you don't have ...

This could simply be a failed button assembly with the left button stuck ON. Remove the four screws from the back of the case and carefully open it. Unplug the button ribbon cable from the circuit board. Now try powering up the CA to check if it boots properly. If this works, a replacement case part...

Hey teklektik, you better read IMR Batteries' Shipping Policy again, as you don't seem to understand it. It still stands: IMR Batteries ripped me off, and they could well do the same to others. :lol: Not only can I read it just fine, but I actually understand it - their policy regarding delivery is...

It's always distressing to see someone become a member of ES because of a sudden burst of 'Public Service' to warn others (aka 'throw a tantrum', 'get even', 'damage business') with a post that will live on for years to come. You requested special delivery handling directly with the carrier. This is...

From section "5.6 Auxiliary Pot" of the Un official Users Guide (page 38): CA3_Custom3PositionSwitch.png Unfortunately, your wire color description does not match the posted "7-wire" photo... So - two answers: By the photo: from the throttle "3-Gears Public Wire" : red -> CA-5V grn -> CA-POT blk -> ...

Does anyone know the resistance is for the molded shunt that comes with the V2.3 Standalone?

1.403 mOhm

...nothing happens when im paddling I will PM you with repaired firmware this week that will address this issue and we will fold the repair into the upcoming 3.13 release. hey eem29! In case you're not getting PM notifications, I sent you an alpha version of 3.13 to try. This should fix the problem...

I have a 52v battery that was charged to 56.5v So - I'm guessing this means a 14 cell battery that you partially charged to about 92%? the CA says that I used 17.5Ah. Sort of meaningless without knowing the actual capacity in Ah. Sorry, but you never actually described the issue. This value is too ...

Just need to make the curve a bit less fat and then I can get it cut! Perhaps something similar to this using simpler geometries and keeping the lines parallel to the existing frame where possible for cosmetics. photo_2018-10-14_15-51-30b.png I'm still trying to find a lasercutter/watercutter in th...

I have RPM working , aux been set PAS level working but nothing happens when im paddling Well two things: You have a configuration issue: Screen Shot 2018-10-14 at 12.20.25 annotated.png Set your throttle mode to PassThru and all will work fine. By setting throttle mode to Speed the throttle is sup...

Turns out that it wasn't the CA, but instead an incompatibility between the controller (25A Grinfineon) and motor (TDCM_305_IGH).... Justin was saying that everything worked fine in sensor less mode, but not in sensor mode. ... Whoa - that's amazingly strange! The sensorless vs sensored mode does e...

In the CA v3.1, is there a reason that the Plim setting can only go to 100w in low range (shunt calibration range), and 1kW in high range? There is no such limit. Here are the default values for 3.1 - your observed limit is not in play: CA3-1_HiRangePowerLimit.png And is there a way to change this....

Ok - thanks for the clarifications. Do I need to use a computer with a TTL cable or is doing the factory reset from within the CA3 menu enough? I don't have a TTL cable, but I am in Vancouver and can stop by the Grin Office. I'll do the factory reset on the CA3 menu to start with anyway. Depends. Tr...
