All in One PCB

Thanls very much for going to the trouble of finding that. Pretty sure both the components will need replacing. Not too sure im confident enough to rebuid the traces though

Same problem on two PCB. Everything good, just smoke when I enable ā€œdriveā€. Even no motor plug on the cyton. PCB dead teensy dead. F9p and bno ok. Iā€™m scared to try again, Iā€™m waiting for the PCB standard 4 to have a better luck !

Anyone had any luck complaining to jlcpcb about these problems?

Are your burnt track problems due to poor handling or use of the engine?

Burn with no engine plug. I donā€™t know what s happened. Just press ā€œdriveā€ on ago and smoke.

I just got started with a standard version aio pcb. By testing the circuit a bit, I discovered that pin 1 and 4 of the amp socket are reversed. So we reverse the 5v and gnd. Has anyone seen this before?

Based on these two boards burning the trace, is this the trace that needs to be bypassed from the cytron to the ampseal or is this a new issue?

Did you boot with your Ethernet Dongle, or just plugged in after powering up windows?

Sometimes its necessary to reboot your laptop after plugging in or change the ip-adress.

I would love to know what caused mine to go up in smoke. And if i can prevent the same thing happening again and to help anyone else would be even better.

Just curious what sort of fuse protection you have on the system.
An easy way to prevent the same failure in the future may be a smaller fuse?

I did have a fuse on the main power lead. There was smoke coming out of the pcb before it blew

What was the fuse rating?
Just curious.

Was 10amps but since learnt that was way to highšŸ˜”. Could be a 3 or 5amp.

We use 12V motor and 7,5A on some tractors didnā€™t blow under operationā€¦
But our motor can take 6-7A peak, so some actually needed 10A.

For standard board:
Did you test the 12->5V regulators?
There are 3 of them. 1 goes to Teensy 1 goes to F9P (these are the black cubes) and thereā€™s a 3rd one which is for WAS 5V

All these gets powered by a diode which is the very first entry point.

For the 12V motor I had to bypass this and simply gave 12V to the cytron as that first diode can only take 3A-s, and thus we didnā€™t want to risk it.

Using 24V though shouldnā€™t be powering the Cytron through that diode thoughā€¦
On the standard board there are only 2 regulators. Micro has a third

I have been using a 5 amp, but maybe thinking I should put a 3A into there until I know all is workingā€¦

Wont the fuse only protect the pcb from something going in. In my case the problem was inside and by the time the fuse blew it was too late, weather a smaller fuse mightve helped me ive no idea :thinking::weary:

care to share a picture of your BBQ edition PCB?
(it wonā€™t help with that board but maybe the next board of yours, or someone else board?)

I know that had to hurt after all the struggle. Do you have spare boards?
