Bed temp will depend on the material used, for instance, when I print PLA I use 60C bed and 190C extruder. What is important is to make sure that the bed is prepared properly. I use a glass heated bed and clean it each time with IPA before each print, seems to work ok then. Some people use hair spray etc etc.

No need for any "tricks" to prepare the bed on this thing :) just needs a quick wipe to clean the bed and away again :)

Yeah I don't get the whole hairspray thing either, just clean it with IPA and off it goes.

50c bed, 200c head... Changed the retraction from 1.3mm to 1.5mm...

I must say the results now are really sweet! There's pretty much no stringing anywhere, the top of it prints really nice now, and the odd line I had across the middle is now gone!

The edges of the square look rough but they are almost smooth...

So ABS seems to work pretty nice now.. got at least 2 reels of the stuff, so at least can use it up on something now :)

In that photo the bed doesn't quite look level with the missing skirt in the front left corner.

I think there is a delay to when the filament actually starts coming out, the head has already moved, so it misses a line.

EDIT:
I will try experimenting with the retraction some more, as that is likely the problem...

Have you measured the dimensions of the dummys? I want to know where they are compared to mine :) You'll need a caliper ..

I'm impressed by your persistence with ABS. I've only used it a few times, PLA is sooo much easier to get right ...

Yeah, though just trying to get it all setup right from the start :)

Will mess with PLA later if there's time...

Problem with ABS is it sticks to the base like glue :roll: heating the bed makes it easier to get off, but its starting to melt so ends up damaged as I am trying to get the thing off... Need it to not stick as much :lol:

ABS suffers from shrinkage so you'll probably get a lot closer to 25 with PLA. Also, it doesn't stick as bad ;)
