Re: Resume from a Power Outage?

I've attempted to restart failed prints with some success but it is never perfect - and it requires a deep knowledge of gcode. I've done a restart (not from a full power outage, but from when I had a filament break and had to re-feed and re-prime the extruder). It took some careful tinkering to fin...

Re: Looking for builders or assembled units

Thanks for the leads. I've read the build manual a few times now and can visualize it. My initial concerns have subsided so I am in the process of acquiring all the tools other items not included with the kit. Shouldn't be long now... Thanks and regards, Peter Have fun!

Re: Assembly manual discussion thread!

They're actually not symmetrical. You'll notice that the hole spacing is farther apart on one side then the other. The 4 bearing holes make a trapezoid and not a square. Ya, that's true. I just meant that the centering of the delta arm mounting bracket on the skates were symmetrical, so even if you...

Re: Finished my build

Anyone have a temp or speed they stick with using PLA? Congrats! I've been using bed at 60c and hotend at 205c for PLA, which seems to work pretty well for me. I found that the fan shroud is a pretty good indicator of machine calibration - setting the extruder steps/mm and filament diameter is espe...

Re: need to adjust the bed, how?

I'm going to look into that acetone smoothing. My students badgered me into making a big green Yoda head and it has a few rough spots. It's pretty easy to do. Acetone isn't especially dangerous (except for being flammable), and it's very fast! It eats plastic like crazy though, so careful not to sp...

Re: need to adjust the bed, how?

Going to try the updated firmware and calibration process. Using ABS, 218 C extruder temp & 80 C bed temp. Using Elmer's purple and clear disappearing with same results. Just a thought - if you haven't tried printing with PLA, you might want to give it a go - I've found it's far superior to ABS...

Re: Blew out some pixels in LCD (static)

I don't know if the pins on the LCD would allow that though. Ya, that would have probably worked if I cut them in the middle with a dremel cutting wheel and then unsoldered just the pins.
