Thanks for the quick reply. I was looking at remixing https://www.thingiverse.com/thing:3297874/files to work with an existing rail corexy carriage w/ bltouch. equal/circumferential cooling around each hotend is what I'm envisioning as seen above. Trying to go a lot cleaner on the wiring, if I can build myself a nice quick release for hotend cabling and more swappable hotend. Not that I really need it with a kraken in place, but anyhow... 0_1555191316003_IMG_3185.jpg

Hi!

I've just upgraded to a 12v kraken. I've got the Kraken up and running great now, but I need to get cooling on the parts. I'm looking into the Berd-Air cooling world. From what I understand, I'll need 4x berd-air pipes going to 4 different pumps. I've ordered the Parker Pump from American Science and Surplus(12VDC AIR OR GAS PUMP). Looks like it'll deliver even more than I'll technically need. Question with this though. Are there enough connections, and what is recommended to get all 4 of these pumps PWM/ESC connected? I'm not new to electronics, but this is a new arena for me. Any assistance is appreciated.
