I thought it's a power supply issue since the heatbed requires a high power draw. We still don't know exactly what part was culprit. If you installed the 5th tool head and the issue is back, you might want to swap power supplies.
Glad to see you have a working printer! For troubleshooting, the vast majority of the time the issue will be an active component, such as a board, vs. a passive component, in this case the wiring. I am not sure about the heads, but my money is on the board for the heatbed, like @huntliba. The heatbed board also draws the most power of the changed components, so in theory it should have the most impact on the operation of the printer. Best wishes, and I really would like to see some prints after all this work you've put into it.
@@monkeybraincreations I'm looking forward to seeing the quality of the prints. Also, I admire your perseverance. In retrospect, the fault was always going to be fixable once you had the necessary parts. It is a shame you had to get another printer, but on the plus side you're letting other people learn from your experience.
On my XL I had a damaged CAN Bus wire for the controllboard of the heated Bed. That caused a short in the CAN Bus and Killed almost all other Controlboards
@@monkeybraincreations Yes, the XL causes much more Trouble than any other Prusa. Even the Software/Firmware is not fully developed yet. Most anoying thing for me is currently the USB reading Error.
in that case... maybe the wires.... because you got error only by heating the bed... tools should not come to play... but what I know... maybe firmware send some commands to other parts too if bed get hot enough...
So.. you have 2 now? damn.. don't like so double down? keks. Good on you, what I don't like seeing is a company who puts out a printer (Prusa/Creality/ etc) and they make YOU do their work for them. Bare minimum, they need to plug boards in a test them prior to sending out to you. They tout how Prusa as a company is so thorough.. this used to get them points when compared to a Creality who just plain sucks at everything, but now.. they have def fallen into Creality territory with their quality.
They did finally offer to refund the printer since I have purchased a new one. I declined and they offered an extruder and 1 package of filament. With a faster response time, this would have been a great solution on their end.
Prusa is not good value for money. I guess its cool to be able to tell others that you have a prusa, but they have definitely gone down hill as of late. Between moving away from their open source roots to the quality control issues they now seem to have, the tax they demand just isn't worth it anymore.
