A little while back I got myself a second hand LulzBot Mini off eBay.
I’ve had to replace a few parts, including the RAMBo Mini board from http://www.3dmakerworld.com/mini-rambo-electronics.
Luckily, doing all of this has fixed the problems that were present in the printer.
On the downside, the fan to cool the electronics is constantly going at full pelt as soon as the power is switched on.
When connecting to Cura, it stops & then spins up again (as it would normally do) but then continues to go on at full speed again.
I’ve checked it’s plugged into the correct pins.
I’m wondering if it’s because the new RAMBo Mini board is faulty, or if there’s something I should change in the firmware, or something else I’ve not thought of. Any suggestions?
I do have a second, fully working LulzBot Mini which I can swap parts from.
Tonight I plan on plugging the fan from the working printer into the other to rule out a faulty fan.
