Topic: Messed up firmware, software, or settings?
I think I may have messed up something in firmware, software, or settings.
A few months ago I attempted a firmware update on my Solidoodle 2 to allow for PID control on the heatbed. I ran into a few issues and ended up having to recover by using an Arduino ISP to reflash the printer's firmware. Also I had to change a couple lines to make it work right (like add the line at the start of the main which tells Repetier that it has adjustable speed).
About the same time I updated Slic3r because a few parts failing to slice and the update appeared to fix that, unsure if this could be related or not.
When I finished it'd done some quick test prints and it seemed to work fine but now I've noticed that on larger parts the estimated time is WAY off. It used to be "fairly accurate" within say 15 minutes on a 8 hour print back when the printer was totally stock but now it's about a factor of 3-4x error in the estimated print time to the actual time. Yesterday afternoon about 3PM I started a 12-hour print and at 200% speed it didn't finish until this morning around 7AM. even though the estimated time at 200% was only 6 hours.
I've also noticed my printer doesn't "jump around" as much, I recall the whole machine used to nearly shake itself off my stand at 200% speed and now the frame just quivers a bit.
Can anyone give me any suggestions where to look?
