ALLLLlriiiiiight guys this is the penultimate post that yall have been waiting for. Have you? Who knows - anyway this is the final “build phase” post. I’ll hide the last few pics in a drop down so as to not spoil the final product, as the next post below this will have the final build pictures in it.
So we left off in the last post with the skinning of the enclosure, and I will have to say that I probably could do a better job on the front part. It’s not bad bad but some of the wrinkles on the edges are coming up a little more than I’d like. People that have been wrapping for a while probably could do it without that happening, but it’s alright, looks fine to me.
Interestingly enough, a package arrived that I wasn’t expecting (wow that never happens lel). The MakerX heatsink arrived just in time for me to be closing up the enclosure! Thanks @YUTW123 for helping me out and letting me buy the heatsink separately from the ESC.
I was thoroughly impressed with this heatsink. The machining and anodizing look great, and it’s a solid hunk of metal. Since the MakerX retro has 6 fets on each side, it’s got a solid metal upper half and solid metal lower half.
Since the metr pro that I got as part of the group buy won’t arrive until Monday, (and for other reasons) I stuck one of the temperature probes from the BMS on the back of the MakerX so I could monitor the true temperature of it. The other temperature probe is about in the center of the pack, pressed on a battery terminal to monitor nickel strip temperature.
Included with the MakerX heatsink were two long thermal pads which I cut up and installed onto the parts that contact the fets. After installing it and MESSING WITH VESC FIRMWARE FOR 2HRS (rant later don’t worry) I could tell that the heatsink was doing its job.
Anyway, I installed the heatsink on the ESC and tossed it back into the enclosure. Now it was time to install all of the neoprene padding into the whole enclosure, around the battery, and as a gasket.
I did actually add a little bit more closer to the ESC since there was a little bit more gap.
I finished screwing in all the enclosure bolts (16mm or 20mm depending on where on the enclosure), I was able to finally close up the board. This literally took so long and I had to widen all the holes in the actual enclosure to make them fit as expected. No one ever tells you how finicky this part is, but I will say it is much easier to do through-deck bolts than these inserts.
Took one last picture before cutting the griptape and installing it. Looks pretty epic as is but the griptape gives it that special touch. I kind of like how the black wheels look but the blue wheels are going on anyway.
I got some pretty awesome looking grey camo griptape to stick on here, and I wanted the carbon fiber to show through, so I made a large diagonal cut through the center. I needed to make sure all the lines were straight so I used a big carpenter’s square and cut it all out.
One last thing before the pics. VESC TOOL RANT OH MY GOD.
LITERALLY %$%&%($*%$#@&@( why is vesc tool such a pain?? I am not going to go into all the errors that I had because it’s literally just so annoying and I don’t want to relive it again. Here’s the basic breakdown:
1: MakerX ships with firmware 3.65, okay no big deal, plug into vesc tool 2.06, update bootloader, and install 5.1. Sure, no problem. Configure motors, everything is good, UART remote just works automatically, cool. Switch to BLDC mode, cool.
2: ensue: smart reverse sucks. The braking is bad, it couldn’t even pull me back up a hill or stop properly, if you’re rolling backwards, you can’t brake properly… I literally just want current brake no reverse. HOWEVER, NAH. You can’t seem to set current brake no reverse with a UART remote. Someone please explain to me why this is a thing. I tried everything I could think of, but nope. No matter what I’m stuck with smart reverse.
3: text @KaramQ and complain to him. He ends up insisting that @pookybear swears by 3.62. Alright cool, fine I’ll rollback to that - more problems. couldn’t read motor config, “vesc firmware not updated” etc etc. I ended up fully starting over on 3.62 and just configured everything with the things that VESC tool wanted me to. FOC mode, UART, nothing else. Okay great it works now, and for some reason, smart reverse on 3.62 is better than on 5.1 Who knows.
- smart reverse still sucks. Braking with it is weird, if you lose traction while braking, it freaks out and starts trying to reverse. Is this normal? No idea. Anyway, I am literally so done with dealing with vesc tool, 2+hr in one night was enough for me. I’ll deal with smart reverse for now and try to learn how to brake without throwing myself.
I hope no one is offended by this rant, it is just my experience tonight, and I really don’t consider myself a noob in this area, so I’m not sure what was going on.
The final question, I don’t want to have to tag @Trampa but really, why can’t you activate anything except current with smart reverse when using a UART remote? Am I doing something wrong? FW5.1, FW5.0, FW3.65, FW3.62 - I couldn’t figure out how to do it. I don’t want to have to use PPM because I feel it’s outdated and when I receive my Maytech dual trigger from @kevingraehl I want to use UART and get the telemetry.
Anyway. Rant over, enough negativity.
Here’s the exciting part. The build is unofficially out of the “building phase” and has moved on to the testing and upgrading phase. The outstanding tasks that still exist are: install Maytech remote when it arrives, install metr pro when it arrives, order and install Riptide bushings. I’m still waiting for the charger for this so I had to make an adapter to use my old one for now.
Here’s a few pics of the griptape installation that kind of spoil it before looking at the real final pics:
