Re: Can't control fan using Reprap Ramps 1.4 RRD Fan Extender - 6 years ago
QuoteDust repeated here, since you don't seem to be looking at your other cross posts asking the same thing. So apparently you have one of these As all earlier board don't have a servo type connectors D12 and D11 are both PWM pins M42 P11 S255 and M42 P12 S255 should work You have wired the expanded correctly? Ie the two pins go to 12v and the 4 pins in a row are for the two fans ? Uby Stigi - RAMPS Electronics

Can't control fan using Reprap Ramps 1.4 RRD Fan Extender - 6 years ago
Hi! After spending hours and hours going through the search results on the Googly thing, flashing the firmware and trying stuff out, I don't know what to do. I'm using a Fabrikator Mini bought from HobbyKing, and I'm trying to add a software controlled fan using the Reprap Ramps 1.4 RRD Fan Extender. Fabrikator Mini uses a MKS Base v1.3 board, although I've seen another Mini with a 1.4 board. Anby Stigi - Controllers

Hi! Thanks for your reply! None of the instructions I saw online matched my configuration, so I thought asking the authors wouldn't help. It's an MKS board, but I thought RAMPS is something MKS uses too. I'll ask in another section. Thanks!by Stigi - RAMPS Electronics
