I did everything exactly according to plan. Even ran it with the cables attached but the extruder itself not, as soon as i plugged it in it exploded. I doubt whether a wrong polarity on the heater cartridge could be the culprit

2 years ago what steps did you do after hardware setup. I have the sprite pro and the SKR mini e3 2.0. I cant get the hotend to heat. Also when i preheat motherboard turns off and reboots

Mine did the same thing, the fix that I found was to reverse the polarity of the hot end on the board, in theory this should not matter but for some reason, the positive of the hotend is shorted to the frame on the sprite so having it connected the "positive" connection it will short the mosfet and cause it to short/click when powering.

@dilboswaggins Same thing happened to me (except I have the SKR Mini E3 3.0) and I fried my board or the extruder; the ribbon cable got super hot and started to melt the plastic connector and it sent out white smoke at the extruder's breakout board. Thankfully, I had a spare SKR Mini 3.0 and just got the replacement Sprite Pro.
How did you reverse the polarity of the hotend on the board? Are you referring to reversing it on the SKR Mini 3.0 or on the Sprite Pro's breakout board?

2 years ago I have a SKR Mini v2 and got the Sprite Pro Kit (with ribbon cable) I'm just cautious about this problem before I try it out, I used a multimeter and not have encountered any short between the frame and the positive heat pin. So any updates about what is causing this problem is welcome. I will update this thread after installation and report anything.

In order to change the polarity I just reversed the negative and positive concections of the heating element where it plugs into the board, so put the negative in the positive and the positive in the negative

2 years ago I think I know what is happening here:
In the pinout manual of SKR MINI E3 (in my case, V2.0), you will see that the pinout is the reverse of that is shown in the Sprite Pro manual.
You need to plug the pins like the SKR Manual says (connector HE0): (https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/blob/master/hardware/BTT%20SKR%20MINI%20E3%20V2.0/Hardware/BTT%20SKR%20MINI%20E3%20V2.0-PIN.pdf)
Just tested it and it works.

anyone have working firmware for e3pro, skr mini e3v3, sprite extruder, btt tf35v3? or at the very least uncompiled sprite firmware?
Dont know if this belgons here but i see no other way as how to report this. I recently purchased the new Sprite pro extruder, and after installing everything correctly and checking everything three times. I started it. I forst started it without the extruder attached and everything worked fine. As soon as i connected the extruder, the processor blew up. Switched to the stock board and it runs fine. Is this a known issue?
