<![CDATA[SoliForum - 3D Printing Community — Supports stringing off model]]> https://www.soliforum.com/topic/15433/supports-stringing-off-model/ Mon, 29 Aug 2016 23:15:59 +0000 PunBB <![CDATA[Re: Supports stringing off model]]> https://www.soliforum.com/post/126619/#p126619 Looks like support distance can only be set to 0 or 2 in Slic3r sad

I did a test print of 4 cylinders

20mm 15mm 10mm and 5mm

all 30mm height and came out perfect,

I then tried 5, 4, 3 and 2 which all failed / were jaggy.

This does appear to point to the speed being the issue as 5 worked when paired with 20,15 and 10.

I might try print a bunch of 3 and 2's and see what happens.

Worked without issue, looks like I finally have my settings. (touch wood)

Additionally I had someone else reply to suggest setting the support distance from default 2.15 to 2 or even 1.5

Now I know re smaller parts too so I have a few ballpark settings saved now.

fingers crossed.

Yes you can get a ballpark setting but it will still need to be tweaked for every part. It all depends on geometry. Larger parts can be printed faster but small parts need to be printed slower and often times requires them to be printed in multiples or print something else on the bed at the same times. The trick is to allow time for each layer to cool before the next so that sometimes requires something else to be printed so the hotend moves away from the smaller part for a while. Getting the settings right for each print is the hardest and most troublesome part of this hobby.

Apart from the support issues of late I was previously able to print without issues at a decent speed.

Hrmm I'm so lost sad

Cooling set to Auto and minimum layer time 30 seconds

EDIT

I didn't read the settings correctly, Setting the speed required all other settings to be 0 (Which I didn't do the first time)

Trying again @ 30 mm/s now with 100% cooling (except first 5 layers)

If that fails ill try 10mm/s

EDIT EDIT

So, 30 mm/s failed (but probably best print so far)

trying 10 now (2 1/2 hour print for a 5 cm tooth...) If that still fails I can focus my attention elsewhere..

Update:

All settings at 30 mm/s still occurring sad
Cooling @ 100%

Foudn the setting in cooling to set layer time minimum from 5 - 30.

Print time now gone from 45 mins to 1:45..... fingers crossed.

Their default for fast printing is 40mm per second. Medium and fine are even slower. The Da Vinci is not a fast machine and should not be run over 40mm per second without a different hot end design.

The only other thing I can think of is maybe the infill is too low (5%) ill try a 100% on it to see if i get same results then work backwards.

These are supposed to be smooth sabre tooth tiger teeth.

From left to right the only changes have been cooling

100%. I've always on Automatic Off

Slic3r .32 layer heights
Abs
Da Vinci 1.0a firmware flashed with repetitive
Extruder 230
Bed 100
3 top and bottom layers
