My printer finally started giving me some problems while printing and even though I already changed the heater and thermistor, it was stopping right before the first layer of my print was finished. I have also changed the hot end ptfe holder to the aluminum due to the other problem I had with the filament melting through the threads and loosening the hot end. So I got this 12v 30 amp power supply through amazon and just finished installing it. I have the original craftbot printer from the indigogo which had the old computer style power supply. The new cb + power supply has been updated and it's now 24v instead of 12v like the original. I had no problems printing what I needed with 12v, so this is why I decided to just get a 12v power supply. I also have a few 12 v spare heaters so I might as well keep using those. By the way, craftuniquie does not have a 12v replacement power supply, just a 24v. So you will need to upgrade the heater if you go that route. I can't remember if there is anything else. So make sure to check that before starting/buying anything.
Once I measured and cut the length I needed for the plug side, I then cut another piece from the leftover cable to make the extension that connects to the board from the power supply. The board only has two wires, a positive and a negative. I just strip the shielding enough to allow me to separate the wires and then I just cut the white wire from each end since you have three wires there. I used the black for the positive like the original and the green for the negative/ground which is what the psu uses too.
NOTE: Make sure to plug and test the power supply before connecting the board just to make sure you got your wires on correctly. This way if the power supply doesn't work or fries on you, you don't do that to your board. Once I verified that the power supply turned on correctly, I took my multi meter and checked the voltage to make sure it was 12 v exactly. You can change that a bit with the pot next to the LED, but this one came spot on so I didn't need to do anything.
Green is ground
White is neutral
Black is Load or Hot
This is the power supply I bought from amazon.
And here's the video of the power supply turned on.
Update: I decided to make a new part to test out with the new power supply. Unfortunately I am still having the same problem. The temp goes up to 211 and stays there most of the time. It eventually crept up to 212, then once the second layer started the temperature started coming back down again. And this is when the clicking started, again. So I have now changed the heater, thermistor and power supply and still have the same problem. I can't get this hot end to go higher than 212 c. The new file is saved to have a temp of 215 c which is the default for PLA on the firmware 1.1.7864-2015-11-27.
Predator version 1.1.8263-2016-01-09/2. So at this point I have no idea what's going on since I have also checked the parts and they are within specifications.
One other thing I forgot to mention is that you will now hear the fan on the back. It's temperature controlled, but once the bed and hot end heated up, it started going. It blows air out to the back. Other than that, it seems to work just like the original. This one is supposed to have up to 30 amps compared to the original which is 12.5 amps. Of course these numbers can be just an estimate or over rated on these things. I don't have any special equipment or knowledge to test them, but I can make some basic multi meter checks to at least make sure it is 12v.
Update: November 27, 2016
I finally found the problem with the temps. It was an aluminum heatsink that was not letting the extruder reach the correct temps. I changed that to my own ptfe version and all is well again. My printer is back up which is always nice. So having the proper heatsink makes a difference. If it takes the heat away from the block that will surely cause problems/headaches.
