You could even get way with a lighter fan now. I used a peel and stick 5/8" heatsink and an old video card fan. Basically whatever was available in the junk box. System happy as a clam. I did however have heat saturation after printing ABS after 3 1/2 hours. I would get severe loss of steps on all axis and the program would keep printing. Happened a couple of times, always after 3+ hours of printing, and only with ABS. Found the problem to be my stock 180W power supply that came with the printer. As the power supply kept heating up from delivering what amounts to nearly MAX current for so long, the voltage finally drops off to 8.76 volts, then recovers, after about a minute. I had an older 12V/360W power supply from my Christmas LED display that I put in its place and systems been rock solid ever since. Also, I'm set up if and when I transition over to dual extruder.
Yep, it sure puts out a chemical smell. First thing I tried printing in ABS was the extruder holder. So funny, as the first cut at it, the print let go 1/2 way through the job. By the time I came back to check on it, the nozzle was dragging the print around surrounded by a ball of ABS string.It's giving out a stronger odour though.....
Got some aerospace grade Kapton tape on the glass and print sticks no problem when printing ABS. I have to remember to flip the glass over when printing PLA otherwise its next to impossible to pry the print off the tape. Yeah, so one side is for ABS and the other for PLA. Works great! Extra Discount
