Topic: SD3 need help

This was my first print higher than 3mm tall and this seems to happen. Any ideas? Just got SD3 today. I followed all the setup instructions and downloaded the SD2 profile and tweaked it for SD3.

Can someone share all of their repetier printing settings for SD3, and slic3r settings for .3mm and .1mm printing, to make sure I did everything correctly?

Checked bed with a bubble level, it appears to be pretty level.

Also how do I stop those "burrs" on the side?

Re: SD3 need help

I'm guessing you haven't calibrated the extrusion rate yet... ---> http://www.soliwiki.com/Main_Page#Calibrations

The little blips on the sides are where each layer starts they will be more noticeable when you are overextruding but can be dealt with some by the retraction settings in the slicer.

Re: SD3 need help

also is it normal for it to make this "clunking" sound??? check about 12-15seconds in the video

i cant post links or images for some reason so you will have to paste it into your browser.

Whoosh...yes, but Clunk...no

Can you isolate where it's coming from?

Also, you have some lifting (first pic, the print lifted and was carried by the extruder) and curing (in the video) problems.  There are many threads on this forum covering those topics with various proposed fixes (glass, enclosure, hotter bed, acetone, slurry, ABS glue, etc).

Re: SD3 need help

really hard to isolate. sounds like the extruder mechanism or the bar that it slides back and forth on.

im going to try again with some hair spray and updated settings. i also just calibrated my extruder, it was off by 25mm just exactly like in the video

Re: SD3 need help

hmm after the calibration, re-leveling, and using hair spray now nothing sticks at all, lol

Re: SD3 need help

appears that the reason is the extruder is too far from the bed now when printing... however i cant adjust my z stop anymore (the z switch dosen't even touch the stop, the bed goes up as far as it wants when printing)

trying to figure this one out

Re: SD3 need help

don't know what's going on. using the "park" button in the manual settings of repetier host does nothing now, and it's trying to print off of the bed and not center. also trying to print way up in the air.

all I did was level the bed and calibrate the extruder. not sure what's going on.

Re: SD3 need help

you hitting 'home' first ? Park wont do anything until the axis are homed pressing home in bottom left corner of directional area of RH manual tab.

Re: SD3 need help

You level the bed with respect to the axes and the nozzle, not gravity.  http://vimeo.com/55450537

Re: SD3 need help

yeah, that home button I was missing. everything is working now smile  let's see how it works after calibration

i noticed the solidoodle filament settings you download set the extrusion multiplier to .7 by default. since i calibrated it using the firmware method, i can set that back to 1.00 right?

Re: SD3 need help

ok, looking better after all the tuning you guys suggested. still getting lift on the bottom towards the last 30% of the print (even with hairspray). could be a bad thing with taller prints. less of that crap on the sides though! looking better. smile

Re: SD3 need help

What temperatures are you printing at?
Also yeah, make some abs slurry and wipe a bit over the bed, solved 99% of my stick problems.

Re: SD3 need help

Is there a better way to turn it off for the night other than unplugging it from the wall and USB? So far I'm impressed with the sd3 needs more tuning though

195 and 95. Green abs from matter hackers. Their spool didnfit on the holder so i had to chisel the hole bigger on the spool. Is not very smooth so the spool doesn't glide nicely as the filament is being pulled. I bet if i could find a way to make it more round i wouldv get better prints too.

Re: SD3 need help

I could be wrong here, but if your solidoodle is new those temperatures should actually be 215 and 105.
At least that's what the solidoodle people told me on their google groups forum.

not sure, I'm using what the website says. (195/95).  The site says it actually runs at 225 when the host software says 195.

Re: SD3 need help

The best way is to try experimenting at different temps to see what works best for your machine and current roll of filament as there are tons of variables that affect how 3d printing works, I would try as low of temps as possible and still get good layer adhesion and flow rates because higher temps introduce more problems like shrinkage, sticking issues, layer cracking...

What settings do you find best that I could start from? In repetier host I have set 195/95 which is what solidoodle recommends but they also said in a video somewhere that it actually runs about 20 degrees hotter than what repetier host reports and raising it higher may burn out the extruder which I don't want to do!

What's a good low temp for extruder and bed to start from with ABS? And what type of shapes and size model is good for testing this? I'm finding that flat objects with lots of surface area I have trouble getting off the bed when it's done. But tall, thiner objects come right off the bed when printing and move around.

This is the current filament I'm using:
https://www.matterhackers.com/store/3d- … green-1-kg
It says recommended temp 230-240c but I read 230c is enough to burn out the extruder on the SD3.

What should I do??? sad

Re: SD3 need help

195/95 are good start temps... these are SDTemps.   SDTemp=RegularTemp-30degrees... so if you want a real temp of 230C then you set SDTemp at 200C. I think you will find that any of the 'Good' filament(abs) works great at 190-200C it all depends on your hotend as they can vary a few degrees one way or the other.

You are right about the more surface area the better sticking... that's just how it works...let the bed cool completely and they should pop right off. If the taller prints are coming off due to the printhead moving back and forth 'rubbing' then off then you need to calibrate your extruder flow rate... ---> http://www.soliwiki.com/Main_Page#Calibrations and -->
http://solidoodletips.wordpress.com/201 … flow-rate/
If you set SDTemp at 230 or higher you will attempt to burn out the hotend... because 230+30=260C and 260 is plenty enough to start melting the PEEK part of the hotend if the overtemp protection of the firmware does not catch it soon enough... and that happens quite a lot unfortunately.
