Topic: Everything but a turtle is trouble

Hey all,

I got my SD2 last friday and have been messing with it over the weekend. The only thing that actually seems to print even slightly well is a turtle I got from thingiverse. I tried printing a couple different parametric gimble designs but they all failed miserably. The prints just don't want to stick that well. The couple that do stick end up being messed up later on in the print.

I think maybe I need to adjust my belts. Specifically the y belts. There's a light click sometimes when the carriage is moving towards the front of the printer. But it's just one click, not multiple. I've tried the true circle realignment. On the solidoodle official video it says that the rod in the back should be flush with both sides. Mine is always poking out either one side or both.

I've been trying to tune the printer for a couple days now but I just feel like I'm messing things up more than I'm helping. I used a .305mm feeler gauge to attempt to level the print bed, done the true circle realignment and have tried adjusting the print settings for a thicker first layer. I have also adjusted the z tab adjustment.

It still prints not very nice circles and pulls the print off the bed.

I'm going to grab a glass sheet and hairspray first thing tomorrow. I just want to know if there's anything I'm overlooking or something I've been doing wrong.

Even with default settings on slic3r it's not printing very well.

I'm looking forward to your responses. This forum and its community is one of the main reasons I bought a solidoodle(that and the price big_smile).

Thanks all

Re: Everything but a turtle is trouble

Clearly your problem is that you're trying to print things that aren't turtles. I recommend just printing more turtles tongue

Edit: Are you using ABS or PLA?

SD3 w/ RUMBA (8825s), merlin hot end (in pieces). Ender3 w/ silent board for PLA printing. Ender5 w/ silent board, e3d v6, new z lead screw, and glass bed. DiY Kossel w/ smoothieboard (in pieces). Vellman Vertex (in pieces)
Shapeoko2 router in process of being converted to laser engraver (in pieces)
Multicam 5000 series CNC Router w/ 11HP spindle, 5x10' table, and auto tool changer (in pieces)

Well gimbals are cool and so are penguins so can those be exceptions to the turtle rule?

And I'm using the 1.75mm Natural White ABS from Solidoodle

Re: Everything but a turtle is trouble

Well, keeping in mind that I'm still waiting for my SD3 to come in, so I just know what I have researched, there have been a lot of problems with the aluminum beds warping when they get hot, so leveling might not help all that much. That's why the glass bed or ceramic tile route help so much initially. Make sure to give the bed plenty of time to warm up.

And yes, penguins and gimbals are acceptable.

Re: Everything but a turtle is trouble

I think it might be an over-extrusion issue as well. At least the first layers kind of look like that could be the case. Though that could also be how the brim that I have set is meant to be printed.

Thanks for at least chiming in TheBaron, and godspeed to the delivery of your SD3. Even with the problems I've been having, It's amazing just to watch the printer work. At first I thought I would just set it and walk away, but I find myself watching the entire printing process with pure amazement

Re: Everything but a turtle is trouble

I plan to use it to get the kinda-step-kids and the nephews more interested in computers and the like. being able to design something and end up with the real thing is a fantastic idea.

Re: Everything but a turtle is trouble

I wholeheartedly agree. Even if you got one child interested in 3d modeling as a result of this it would be great. Could be a future career for them if they have a knack for it

Re: Everything but a turtle is trouble

We have had our SD3 for a few months.  Strictly ABS. I have had many issues with parts not sticking.  Lots of messing around with speeds and feeds and brims and such.

I believe have found a bulletproof solution:
1. Glass bed (more for durability since you want your parts to stick so eventually the Kapton will wear out).

2. Hairspray containing PVM/MA.  They probably all do.  Every cheap one of the shelf did.  The finger pump kind gives less over spray and there are no propellants that could get in the way.

3. A secret sauce of ABS pipe cement cleaner stuff from the hardware store(Oatey #30795, MEK and acetone), with some ABS dissolved in it.  Not too much ABS, maybe skim milk consistency, maybe less. Less is more here.

4. A pump of hairspray on the  hot glass.  Wait 10 seconds.  Paint a single coat of the secret sauce onto the build area.  Done.

Rationale:
1. PVM/MA sticks to the glass really well.  Solvent dissolved  ABS not so much.

2. MEK in the pipe cement cleaner completely dissolves the ABS, acetone alone does not.

3. MEK is a solvent for the PVM/MA, acetone is not.

Big prints small prints, fat prints, skinny prints.  Fast low res or slow high res.  They all  stick.  I don't use brims on prints that are short anymore.  Only tall thin ones.

Good Luck and pass it on if it works for you.

Re: Everything but a turtle is trouble

Hi Jroos, Have you checked out this thread ---> http://www.soliforum.com/topic/1889/the … gs-around/ it has a lot of great tips to get things to stick better. It sounds like you might not have the printhead low enough to the bed remember it needs to squish the plastic to make it stick good.

Re: Everything but a turtle is trouble

I'll look into that page to solve the sticking

How about the issue with the true circle realign?
Is it alright for the rod in the back to be poking out either side?

Re: Everything but a turtle is trouble

Pointing out is fine as long as they are even, not sure what difference it makes???

As for the true circle thing I would concentrate on getting most of the other things zeroed in before starting in with the belts as they can be tricky if other thing are out of whack, then you end up chasing problems around that might be caused by something else... or not smile

Re: Everything but a turtle is trouble

Well I put a glass bed on, sprayed it with aqua net hairspray, and put cardboard on 2/4 sides. The lifting has stopped and now my prints are simply beautiful.

Just wanted to post an update so that others could learn from this.

I think the makers of aqua net should just sell their products only for 3d printing. From the smell of the stuff I couldnt imagine putting it in my hair. Burns your nose hairs right off
