Hey @RyuX awesome build! Do you have your motor set up on the front?
Yes Indeedā¦ mine is on the front right. like to have it in sight
Hey man, yeah just finishing my first build waiting for parts, mines a low rider drop through but i cheated and used a prebuilt carbon deck with an integral enclosure, full marks for the enclosure effort! I was just going to say that as a heavier guy i always chuck my prebuilt in reverse and go up front wheel drive, it seems to pull better than push. How much fun is this stuff? Iām too posh to push lol
I actually never tried a rear wheel driveā¦ but maybe will try somedayā¦ Also The Motor will get less dirty when its in the front and better air circulation.
Well the 6384S is a beast. I can go up any hill - only limitation on extreme hills is that my VESC will get hot because of the closed enclosure (but I rather have it closed to protect it from water and dust). I have heatsinks on my VESC but still when the motor is pulling 50A+ it will get hot quite fast (but those are really mountain village hills then).
So great fun
That is a big lump to be sure wow. Mines running the standard 6374 dual and iām hoping it gets me up my hills as nothing prebuilt likes to. Maybe i just need to lose some weight. I shouldnt run into too many heat issues with dual motors and a 10s battery but i fully intend to chuck a 12s in there at some point so i will be hitting up all these lovely experts for some settings advice soon. anyway man good luck with the developing build and look out for my thread soon!
Good luck for your built. Dual 6374 should make it easy - however I was always aiming at 12S just for the sake of lower KV Motor - high torque - less amp for the same power. Donāt forget your protection gearā¦ got thrown off 2 timesā¦ First time was a full brake at around 35km/h - still donāt know what happened thereā¦ took some time to recover and second time was speed wobble because my VESC went into Motor Overheat Mode while accelerating - so the change from acceleration to idle made me have to jump off the board. However it was āonlyā at 25 km/h so I was able to run it out. I ordered a padded hoodie now and always wear a helmet and gloves now. Cheers
Will add a voltage LED meter based on Arduino this weekend to properly show me the exact range that is left using my own data (I bought a finished meter once - but the range is displayed totally wrong).
Just tried the cooling turbine - and man it cools so well!
Also made a short video of going uphills at half throttle on a really really steep mountainroad. If I hit full throttle the traction will be lost so half throttle is the way to go.
Will upload it later
If you want even better precision of your printer, you should try at 0.2-0.25mm nozzle. It will help alot in the X/Y directions.
Printed out a small RAM Intake for my VESC to cool the heatsinks. Also added a voltage meter and removed the LED Bar (it was not precise enough).
Cooling fan really needed? My old 6354 motors never heated up more than hand warm. I will have two APS 6384s in my next setup and just wondering whatās going on here?
Better Safe then sorry If itās needed or not - cooler motors are better than hot motors. I will always try to optimize my build and not compromise
But if the motor runs cool already then I see no point. Especially, if you use two side-by-side there is no room for two fans ā¦
I would never consider my Motor as ārunning coolā it does get hot - just not to the point of overheating. And I am not running two side by side - so there is room
Looking good. Just saw the pics of your motor fan. I noticed that your 3d print have a few issues. You may need to address a few things before you use functional 3d printed parts.
This is what I think is going on:
youāre printer is over extruding. calibrate the e-steps of your extruder stepper motor. This will improve accuracy of your parts. If youāre still having problems try decreasing or increasing the extrusion width of the outer walls.
your print temperature seems too high. When your printing at a too low temperature your print layers will delaminate easily. Too high temperatures leads to poor print quality. Try to print a ātemperature towerā to determine your materials ideal/optimal print temperature. This will also help improve the precision of you 3d parts.
A final thought - Iād print that motor fan with Carbon PETG. Those fins might fail at higher RPMsā¦just to be sure your safety is not compromised.
heyā¦ Thanks for the input However when I aim at stability I always like to overextrude with higher temp (better binding and more material).
I tested the fan at highest rpm and highest temps and it is holding up pretty good. Its a special kind of PLA and however I donāt like Carbon PETG anymore as it fucks up my nozzles.
Cheers
You need a wear resistant nozzle with a bigger diameter. Perhaps a 0.5mm or a 0.6mm nozzle. I use a 0.6mm from Micro Swiss. Worth investing in if you plan to print a lot.
fair enough. Might give that a try at a later point
You might consider printing a plug for it and keeping it in your pocket or backpack in case you get in wet conditions.
