Spokane Create Delta Printer

[ABearden]

Sweet! If you can do PLA, that at least means the mechanicals were close enough and the extruders were good to go.

I normally do PLA between 180 and 205C, bed at 70C. Rarely have problems with adhesion to the glass as long as I print a good brim, the first layer height is set right, and I wipe off all of the finger oils with a solvent.

ABS I normally print at 225 to 235C and 100C for the bed. It won't stick to bare glass though. I use hairspray and it works well. You can also use certain gluesticks or "ABS juice" which is acetone with ABS dissolved into it (or a small amount of acetone on the glass, then rub it around with a failed print of ABS). Makes cleanup a little more involved than blue tape, but that's ABS for you.

The Leapfrog bed doesn't seem to be insulated enough to manage that well. We may need to adhere some cork to the bottom to help hold in the heat. Fully enclosing the printer would help too (though the top might be hard given how the Bowdens are setup). We may have to modify the bed power setup with a relay and run higher voltage through it to get it to heat properly. Once I have all the printing and machining done, I'll probably do some extra-curricular building during the day.

As for the build, the only thing I don't have yet is the dxf for the feet. If you want to try printing the tensioners or the carriages I haven't started on them yet. I don't have enough blue to do the carriages in the same color as the brackets (though, we have more blue with the leapfrogs). Trying to decide between red or lime ABS. With the light color of the ply, the red/white/blue would look pretty good in my opinion, but so would lime/white/blue or just blue/white. So far, I've got 8/12 brackets printed; took a little while between tuning for these prints and the meltdown recovery. Once I have all the printing and machining done, I'll probably do some extra-curricular building during the day.

Spent all day getting things setup for the frame plates. Given that's some dense plywood, I had to slow things way down from my original estimate. Running at only 15ipm and only 0.05" deep per layer. Takes a little over an hour per plate. Making me really wish for a fullsize mill. One corner of the test plate was a little chewed up from testing problems, but it looks nice overall. Now that I've got it dialed in, the rest of the plates should come out awesome because that is the best machining plywood I've ever worked with so far.

Okay, dinner break over, back to building.
