Adjustable automatic fan activation switch for CTC dual
Description
Often I forget to switch the cooling fan on when I am printing objects with bridging and the result is a waste of filament and I have to print it again. Now i have installed a limit switch which activates the fan automatic after an adjusted travel distance of the z-axis. This is my first share and it was designed to work with my CTC dual. It might be compatible with following printers: MakerBot Replicator 1 FF3DP FlashForge Creator CTC Creator Dual WanHao Duplicator 4 and Duplicator 4X please let me know if it does or doesn't. I hope it will print well on your printer. If not, let me know. You might need to sand the parts etc. Just wire the C-NC contact of the limit switch in series with your switch which you use to turn the fan on. Assembly instruction and needed parts are in the pictures. I hope you can use it!
