Re: Loving Simplify3D

I love Simplify3D as well. My wife Eva jokingly calls is "Complicate3D" but she uses it too. Cura is great to begin with as it makes the printer as close to "plug and play" as is possible, but S#D is a big improvement. There are a couple of things that I haven't figured out: 1) I can quite get it to...

Re: Marvin print stops extruding at ~50%

What does the temperature on your head read, just as the print fails? I suspect that the large cooling fan that cools the part as you print it is coming on a bit too much or a bit too suddenly and cooling your print head. Cura, by default, dials in more and more cooling fan as the print progresses. ...

Re: PLA Heat Creep - SOLVED

Here is a link showing a Hexagon hotend disassembled: https://tamarintech.com/article/hexagon_std_assembly As you can see, the finned section is separate from the heated section. The "heat break" is a separate threaded stainless steel tube. Stainless is a poor conductor of heat, so it isolates the f...

Re: PLA Heat Creep - SOLVED

The fan duct surrounds and cools only the finned section of the hotend. It does not surround or direct air around the lowermost section of the hotend. The finned section is supposed to dissipate the heat from the tip of the hotend. The small blower helps do that, but not evenly or nearly enough for ...

Re: PLA Heat Creep - SOLVED

We often found that we had to extract the jammed filament out of the extruder with a pair of pliers, carefully leveraging against the plastic extuder frame. This led us to discover the bulged/swelled filament, just before the melted end. In turn, we noticed the jams were mostly happening during retr...

Re: Taz 5: Can fan be used on high temp prints?

The simple answer is to run the fan at less than 100%. Pretty easy to do. Either do it in Cura, or you can turn down the fan manually on the LCD display on the printer, but you will have to do it every time if you chose the manual method. The more complicated answer is to replace the standard 24v 30...

Re: dual cooling fans

If you put a fan on the left side of the extruder, you have to be careful not to run into anything when you zero the X-axis. Often, you must put on new stop of the X-axis limit switch to keep the fan from running into the printer frame, etc. I "mirror" printed a regular right-hand fan and mounted it...

Re: PLA Heat Creep - SOLVED

Eva (my wife) and I have had real problems with glow-in-the-dark PLA and other filled PLA jamming (grinding). After months of occasional failed parts, I think we finally have figured it out. We too used a 20x20mm fan, but as a substitute for the tiny blower on the finned section of the hotend. We in...
