look out people !!!! the a5 and a5s can fly in the fire happen several times but jgaurora does nothing about it !!!
a fire broke out at my home the fire brigade did an investigation and came to the printer a5 they searched it and showed no approved food. the fire brigade in the Netherlands has already received several reports of this. there were also a5s between them

Is there evidence that the A5 And A5S caused the fire? Could you please post a photo of the printers now?
We need to get more information about the problem. The MW power supply is industrial standard, it should be build to work under the printers conditions.
I definitely recommend to add a head sink on the Y and E stepper motor. Y would be better to add active cooling.
A fan for the bord would be also not bad and to isolate the hot bed with 3mm cork to prevent heating the lower parts.
Than the printer would have a higher thermal stability.
I found only one video about smoking cables on a "new" JG A5. I think there was something wrong wired at the assambly.
In the end I can say that JG has changed every issue with the printer (earthing the case, MW power supply, Isolating the USB ports, better hot bed, wire management...)
The MW power supply is save from burning out, it would shut down when its getting overheated.
In the A5S they were claiming a high-quality power supply but they did not specify the manufacturer.
Was it simply a bad cable, wrongly mount cable or defect isolation?
His printer was only smoking, the cables in this situation normaly cant cause a fire, they only smoke badly and melt away. But the word fire produce more clicks, I know.
Why didnt he followed the cables and replaced them to see where the problem is. Thats no help to make a video and dont tell the problem. Same as the video with the electro shock, just bullshit.
Maybe it was a short circuit on the heat bed or on a extruder motor, that can happen.
I can only see that this guy has the metal clamps of the heat bed on the wrong position, dont know why he did that but that can for sure cause an short circuit alone!
Had a number of issues but the worst was when it started smoking.
DIssassembled the cable harness to the extruder and the wiring was melting about 6 inches from the extruder which melted the filament and locked it in the tube.
They wanted to talk me through a repair but I simply told them I was uncomfortable with this idea and preferred a replacement... which they complied without hesitation and very quickly.
All responses were quick, curtious and to my satisfaction.
A brand new machine that was tested should not do this.
Playing with the new machine now... it just died mid print.
No idea why.
Started over.
Its easy on every printer to get there a problem because on the heater cartridge the cables are very near to each other. Dismount after testing, shipping and assembling the printer can cause a problem there. I saw a lot of burned wires on other 3D printer because that problem. Its important that the wires are not under tension there and dont get in contact between wire to wire or wire and heat block.
The best is to add the mosfets for heat bed and heater cartridge to save the mainboard from shocks and high voltages.
Howdy, Stranger!
