Vesc Conversion Status (Rose/Mika)

LOAFFETTE

@lia I don't think I could. That bump goes pretty far into the bumper, and I'm worried if I sand too much of it, I'd be puncturing into the box's cavity
apologies for the venting and ranting, I'm just having one hell of a time with this board right now

@loaffette responding to this so people can be updated:
Turns out the Field-weakening setting was set to 45A. When I did a burnout on the ground, I think the field-weakening drew too many amps from the ESC and blew it.
So now I keep my field weakening current under or at 35 amps

Lia

@loaffette No worries, feel free to get it off your chest.
Hopefully it all starts to just drop into place soon for you!

The board is back in one piece
However, there is a problem..

Here it is rebuilt, but in time-out

The board is acting weird. It's very sloggy, and I've made sure all of my settings are set correctly. I am having some weird issues with the yaw orientation, but I'm not sure if that is the problem or not. I'm gettgin 15-35 degree offset, not the usual 90 or -90 degrees

Lia

@loaffette Regarding yaw do you mean it's just drifting?
I could be wrong but on the VESCs I've done with an external IMU the yaw is ignored as you really only care about pitch and sometimes roll.

LOAFFETTE

@lia figured it out
It was some pitch orientation problem. I redid the IMU calibration a few times until I got it working

Lia

@loaffette Congrats! ^-^

Here's some good news:
My board balances in freewheel mode freakishly well
and I am working on making fender deletes for the thunder rails
Currently basing the main design off of Rantharin's work on the fungineers discord, but his is for a pint tire. I'm adding an indents near the axel to make space for ~~rim j-~~ life savers, and a cutout to allow cables to run past unobstructed. I'm currently printing prototype 3

Hello everyone
I'm still alive, just busy with summer internship and stuff.
The board is fine, switched the controller box to an ASA Easy-Access modified to fit the stock XLR and power button.

I will post a more detailed writeup later on, concerning what progress I have made with my board
In other news:

Pushed my board to 30MPH. Stock htpercore motor with 4000 mile old bearings, ubox 100v and the ME4T pack from TheBoardGarage

I may have a problem, and I think it concerns my sense of self-preservation

@loaffette -- I suggest that you might want to wear some armor. A Fox Titan Pro Jacket (with some extra CE padding in the leading shoulder and elbow) has let me get back up and ride away from an handful of high speed crashes. That with a helmet, knee pads, and wrist guards. Also, on my hips, I wear knee/shin guards -- no more bruised thighs.

LOAFFETTE

@s-leon I'm already working on that. Got a new full-face helmet, knee pads and wrist guards. Going to save up a little more and then buy something for the chest.

Alright, update time:
This time, properly.

So, for the past year I've been dealing with a problem on my board. The threads on my rails keep going out. I've had press-fit inserts put in, but they keep falling out. I've JB-welded in some 10-32 nuts, but those don't hold. There isn't much metal left in the rails where the threads are to even do heilicoil.

So, what's man got to do to get his threads back?
You make your own threads somewhere else

The way I see how the onewheel is assembled is that everything attaches to everything. The bumpers attach to the rails, controller and the footpads all at the same time on the XR. The kush wide attaches similarly, and controller boxes are just bolted in with screws threading into the box itself.

So why not just cut the rails out of the picture if they are just a problem? The only screws holding my bumper on are attached to the footpad and controller anyways. So, why not just have the footpad and bumper attach directly to the controller itself?

I took Fungineers Easy Access box and made the holes underneath the footpad screws small enough for heated inserts to fit snugly into. I extended out a small block for each bumper, and added a hole for a heated insert. I'm going to print this out on my new Bambu A1 (I got so fed up with my CR-10 Smart that it now permanently lives inside of its box in the garage). I'll print it using PETG, but I'm going to compensate by making the walls on this thing thick. I'm shooting for at least 5-6 walls thick, and I'm going to crank up the infill to 40 percent.

I'm also printing off a new footpad for the future. My old one has the sensor peeling up on one of the back corners, and it's ghosting on the left side of the board. Going to print off VOW's Mushies in PETG, but I'm going to make it pretty dense and add a couple mods of my own I'll show later.

Apart from that, I'm going to clean up the wiring in the board and make it a little prettier, add an Avaspark RGB Mini.

picture of the box

I had to shrink the m3 heated insert holes around the top because they were way too large for the inserts I had on hand. Made little legs that stuck out, and made the screw holds small enough for heated inserts
I have a devious plan with his

Expanded the holes for 19mm buttons, same for the plug

also, I found out today why my threads on my board got stripped.
apparently thunder rails are tapped for M5, not 10-32
XR uses 10-32 screws
Thunder rails are tapped for M5

my reaction to this information:
sadge

Lia

@loaffette Ouch :(
I think all the Fungineers stuff is metric. Mostly because we're all from predominantly metric based countries 😅

LOAFFETTE

Ubox 100v stopped working after I shorted the 12v Power port on the controller itself. (the unmarked 2-pin PH 2.0 plug beside the SWD one on the side)
{
Emailed spintend to see if there's any fixing it, but this seriously puts a pause on my plans
I did get everything wired up for the LEDs, but it still sucks that the controller is busted.

Lia

@loaffette Hope they get back with a fix. Probably something replaceable has blown if you know someone with a reflow iron and steady hands.

LOAFFETTE

@lia they just told me it's dead and needs to be sent back
I'll probably poke around inside and see if anything looks broken or busted

Lia

@loaffette Assuming the fuses did their job you should be fine.

https://spintend.com/products/single-ubox-100v-100a-motor-controller-based-on-vesc

Check continuity between the highlighted components. If one shows Open Loop then that needs replacing with another fuse.

Good luck!

LOAFFETTE

@lia I'll check
if that's the problem and the board powers on afterwards, then I'm golden

I did notice earlier that when i have the power button plugged in, there is that little pop, but still no power

LOAFFETTE

all of them seem fine, but BF on mine is a tad bit flakey
