I'm looking to do the fan mod to print better in PLA. Can anyone tell me whether I can tap off of one of the other wires around the print head - or maybe from somewhere else?
What I did was made a y connector that goes into the other fans 5v area to put in a 5vdc 50mm fan.
For the transition between the PLA and ABS, the setting that causes the most problem is the bed: It deforms more than 90 ° to 50 °
Either there must be the same temperature for ABS and PLA or it must play with paramettres of slic3r to an offset for the PLA (I have about 1mm)
To fan the only solution is to connect it to an external source and turn it on manually (I'm talking about the fan to the PLA)
For your extruder does not heat enough, check the connector because there's sometimes false contacts
I have yet to find a radiator to cool the top of the extruder so I can not tell you more
Guess I wasn't logged in.. sorry about that.. I also see that I need to trim the radiator a little to allow some of the air to escape down to the other unit on the side of the heater block.
