did u flash in the bootloader before u flash in the firmware?

The firmware page does that automatically itā€™s not an option. It only has ā€œgenericā€ loaded in the bootloader tab

More weirdness, just rebooted, VESCtool only sees one VESC on CAN and then I just hit ā€œdetect all motorsā€ and they both actually did something, got the message ā€œcannot write motor configurationā€ then got detection results, which actually look correct.

Wtf is going on.

It works now even though I got errors and didnā€™t see what I should have seen, and this scares me, how do I know this wonā€™t screw up halfway down a highway?

Iā€™ve never had an ESC be so untrustworthy since my last replacement tenka

Usually the second detection can be written normally. If not, restart vesctool and ESC.

If it makes you feel better, this is how Vesc tool acts on any dual vesc setup. Itā€™s so frustrating. Connecting to different sides of the ESC / rebooting the ESC / reflashing FW / rebooting your computer and doing other such things is how eventually you just get it to work. I also feel extremely uneasy about the thing once settings do get applied (especially if the ESC had forgotten its settings just a minute ago!), but it usually works out alright in the end.

This is why I strongly prefer single MCU ESCs these days, because those donā€™t seem to have these issues.

Got any pics of your solder connection?

Do we know why this happens? Is there anyone here qualified to answer this question? I donā€™t see this kind of stuff happening to any other of my devices really. So it must be solvable. Seems to be a vesc issue, not specific to any hardware

Does @Blasto pop his head in here nowadays? Iā€™d think he would know if anyone would

#417

Someone could always dig through the VESC forums to see if anyoneā€™s brought this up.

#418

Iā€™ve seen it happen more with single MCU VESCs anecdotally. But what a wacky and inconvenient problem nonethless.

Same. It happens quite often with unity/xenith, canā€™t remember of any reports with stormcore tho.

Happened to my stormcore twice. Once it happened while I was working so I had to steal a Hoyt uav from a local rider to finish the delivery :sweat_smile:

Weā€™ve seen it several times on Stormcores here at the shop.

could I wire this up to one ebike motor and have double the current?

#423

I believe that is known as a super single, but (someone correct me if Iā€™m wrong) requires special firmware to run/be wired in that way.

not only it require special firmware, it also require a single mcu dual power stage (aka phase) esc, which at the current market, only stormcore D series / xenith / unity will be able to do that

so the answer is no, not any of makerx esc can do that

Iā€™ve been noticing my D75 takes a lot longer to start up than any other ESC. It takes about a good 5 seconds from when I push the button to when the motors respond to the throttle. My DV6, DV6+, tenka, hobbywing and evolve ESCs all start up in a fraction of the time and all of my VESCs respond almost instantly after power on, why does the D75 take so long?

#426

Seems pretty standard for a vesc based esc to me? What are you using it for anyway? A get away vehicle?

Living with chronic anxiety, every vehicle is a getaway vehicle.

And this VESC is noticeably, painfully slower to start up than anything Iā€™ve ever used before.

then donā€™t turn it off

Maker-X made that not an option. Auto-off after 10 mins and thatā€™s not a changeable setting.
