A software engineer by trade, I built my 3D printer to be able to help me build up my model airplane & miniquad experiments. I built it from a kit, and then upgraded it several times, each time getting a jump in either quality, or print speed without losing quality. It’s currently running off a Replicape electronics board (thing-printer.com), using an E3D hotend and a 550W ATX power supply.

Can you check your thermistor wiring on the hotend? It could be a thermal runaway alert being thrown because of a short-circuit…

Another fact that I find also affects part strength is (even for a same filament spool) hotend temperature and whether or not it’s adequately cooled. I haven’t measured the exact percentages in a methodical manner, but I know that if I print in the top 10 degrees of the spool’s range, I usually get…

Well one thing you could do to avoid it cracking is also fine-tuning your firmware to guarantee slow heating/cooling cycles of the print bed. Also, you’ll need to find a way to mount it that can handle the slightly higher thermal expansion you’re going to get. Finally, you’ll also want to make sure…

Ack, couldn’t see the original replies and thought nobody had answered. Sorry, first time on these boards for me…
