Yah. but I really do love the how much the prints improved with the e3d v6 and the bondtech I should try your sundial.
Yes, you should. And send me one!
well I am printing it now. will see how it comes out
I spent about an hour picking the holes open on the back, and removing strings. My "1" and "0" were perfect. The second number (hour digit) worked with about half the numbers. The "20 minute" digits were an absolute fail.
But the concept of that thing is amazing.
Did you print it with supports? the instructions indicate to print without supports
But the concept of that thing is amazing.
Yeah, it's a really clever design.
I might give it a go when I get the time.
No, but a S3D raft might help with the holes getting filled in on the bottom.
My first problem was too high of extrusion for the base layer. I had it at 200% and it filled in the holes on the heated plate, so I had to carve them back out with a scalpel.
My second problem was I set the layer size at 0.3.
I cut out just the "20" digit and tried again with 120% extrusion on first layer, and 0.1 layer height. A little better, but you will see when you print it. The intricacy of the "20" digit is insane!
Well I have the sundial portion printed now. I had to print it in two halves what I kept downloading the full it wouldn't slice right.
Letting the epoxy set for the two halves and will go try it out. the print looks really good though.
here is a picture of it.
it came out pretty good I didn't have to do any clean up
Yes it does look amazing. How do the numbers work?
They work from what I can tell (tRied it out by hand at noon) I'm still printing the parts that let you put it on the jar
What filament, heat, and infill did you use?
Just out of curiosity... why didn't you print it all as one piece?
grey 3d solutech pla,
temp 205
The slicer wouldn't slice the one piece one corectly.
I did 15 infill
I printed one half of it yesterday with ABS with no infill.
It came out ok apart from a little bit of warping at one end (my fault, bed not levelled properlly) and it does work.
The half to the right of the colon is the difficult one.
I installed my layer fan yesterday and am pleased with the results on overhangs. But my warping is worse than ever.
I'll check my bed level but I don't think that's it since the first layer went on great.
I feel like the fan is making the upper layers constrict andpulling up the bottom.
IMO, at least with ABS, layer fan can't always be on.
That is correct you don't always want the layer fan on with ABS.
With ABS you want to let your slicer control when its on and the speed. you may need to fin tune it by changing the cooling settings.
What works really well for me with ABS is to print the first layer with the bed at 105C and the fan off. I then drop the bed to 90C and turn on the fan for the rest of the print (don't wait for the bed to reach 90C - just keep printing). The hair spray seems to hold better at 90 to prevent warping (in fact my biggest problem is glass breakage as large completed parts cool).
I ran the same print with fan off and although the overhangs look like crap the adhesion was better.
So my plan now is to move the extruder fan to the layer fan holder and reload the FW with layer fan control.
I'll put my externally powered fan on the extruder. Is it ok that that fan is always on? Is 12v worth of fan power going to be too much or is that OK for the hot end?
It's actually best to have the extruder fan on all the time, particularly with pla.
12v should be ok, the E3D uses a 12v fan.
It looks like a 1k resistor and NPN transistor are all that are needed to populate my second fan plug:
