Looks like over extrusion to me.

Did you calibrate your extruder motor?

@prom Never in life! However I decreased the Iniall layer width and it done the trick! 😎

ive been having an issue with my ender 3 v1 with the 4.2.2 main board with the 4.3 in lcd touch screen with a bltouch 3.1 and i cant get the dang thing to work right. i can repeat the same error code 203 but it always fails a probe at random spots each time and some times it finishes just fine.(rarley) just wondering if any clues. ive tried 2 bltouches same issues and i do believe im using the correct firmware

today I'm thinking about converting my old anet a8 into a dedicated laser etcher using the mainboard from my little 1610 CNC Machine I really want to be able to burn in greyscale and I've found out that cant be done with marlin 2.x  I'm thinking it should go pretty smoothly  but time will tell

I find PETG is better than ABS, just as strong, but easier to print and less of a pong, though if you already have a reel of ABS then I guess you would want to use it.

I always wanted to address @byron statement that came up in Inqling Jr thread.  Was about to place it there, but it would seem kind of random there. 😆 

When I remember to address it, I'm always at the library and wanted to add a data point I can only get at home.  When I'm home, I'm doing something that distracts me... and please understand, I'm not trying to convince ANYONE to use ABS.  But I wouldn't use anything else.

I prefer ABS because:

  1. Its a well defined Engineering Plastic in every day life that has been around for decades
  2. It is chemically well defined.  I've found no variability in my printing of it between the cheapest stuff and the premium brands.
  3. Its the cheapest.  I have a pretty good stockpile I got at $9.90/Kg.
  4. Its lighter so that Kg of plastic goes far further in the creation of parts.
  5. I've modified my printer for ABS - Heat box, mod to the print head to be more heat tolerant
  6. I've run maybe... 2 rolls of PLA and 2 rolls of PETG.  Both of those eventually left carbonized plastic on nozzles and required cleaning more regularly.  ABS - I've got more than 50 rolls on the same nozzle and have never had to clean it.  The printer stats say I've printed 80 kilometers of filament, using 535 days of printer time.  I have upgraded the ROM once, so I don't know if those numbers were reset.
  7. My printer (Prusa i3, Mk3) was built with PETG.  One of the pieces failed miserably due to heat.  My fault as the heat box and high temperatures I use for ABS caused it to deform.  It was a very painful process even though I could easily download the STL file for the part from Prusa.  The problem... no printer to print it.  I believe they made a mistake going from ABS in the previous generation to the PETG in the Mk3.  

Cons:

  • Its cosmetics are not near as nice as PLA.  My son does a lot of cosmetic parts and swears by PLA.  I'm more interested in structural soundness, so I've again modified the printer and use Cura settings that increase strength at the sacrifice of cosmetics.
  • Yes, ABS has a bitch of a learning curve, but I'm on the other side of it now.  I almost gave up on it several times early on.  If you only use PLA, assume you'll throw every part away of the first roll!  😔 

Proof of Concept a program I wrote that generates boat hulls from a relatively simple equation.  This catamaran hull portion weighs about 4 lbs.  Each segment fills my printer's volume.  And yes, for those few who have a clue, I AM a University of Tennessee Volunteer!

I've only used one reel of ABS in my early days of getting to know about 3d printing so I will have to bow to your in depth analysis and it appears to be the filament of choice for your purposes.  I don't use PLA any more preferring PTEG but my 3d printing output has only been about 5 reels this year and probably only about 15 reels of whatever since I bought it so I'm probably in the lower usage category.  Its still on its original nozzel and no signs of  any issues yet.

I also have a Prusa - a mk3s but I will be mightily tempted to get the Prusa XL when it comes out, and the pound (hopefully) get a bit stronger to the Euro.  

I was also thinking of trying the Pruserment PC blend carbon fiber for when (if) I need a high strength and high temperature print.  It seemed it could be a good choice for prints for larger robots, but any experiments with it will be in the future.

I now live in an area that is very price sensitive and I've started recommending the Crealty Ender 3.  I know five people with them and they have very good luck with them.  They're all metal construction, so they won't have the problems I've had with the Prusa.  They don't have the auto leveling (Ender 3) and I think I'd miss it, along with the direct drive extruder, but those users don't seem to mind the bed leveling or the Boden design.

I keep looking at the Ender 5 Plus for a large format printer and I like the CoreXY design better than the sliding bed for large format printers.  Less likely to have problems and faster print speed.  I've also considered getting a Voron kit and scaling it up.

Jeeze!  I forgot my favorite aspect... ACETONE!

  • To clean 
  • To thin down and make a paint, filler, putty
  • As a paint, it fills the layers and makes the part far stronger in the inter-laminar direction!  It also smoothes it up.  There's an artist in the area that builds dynarommas - Uses PLA to get the detail, then uses ABS to fill-in the layering.  Then does extensive painting and decorating with other materials and sometime LED lighting to make outstanding pieces.
  • Fusing pieces together is stronger than the printed part
  • Vapor smoothing
  • And besides... I have plenty of scrap! 😜 Makes me feel like I don't waste so much.

Jeeze!  I forgot my favorite aspect... ACETONE!

I've just come inside from working in the garden, but before this I watched the ladies Wimbledon final and McEnroe was one of the commentators, which is probably why my first thoughts on reading this were "you cannot be serious".  Second thoughts were, that inq, following some jocular remark I made to @zander about my left leg getting shorter, he's have a go at pulling my leg to readjust it.

But no, I think you mean it.  When I got my 3d printer and got a few different filaments and denatured alcohol, some acetone,  glue sticks, scrapers etc all of which seemed to be necessary to get going.  Very shortly after Prusa  produced a powder coated version of their spring steel sheet on which to print.  With PETG all of these these extras were unnecessary. No smell at all and once the bed has cooled the print just needs a small tug to remove it.  If I had to use ABS and Acetone the horrible volities vapour would have meant I would have to give up the 3d printing.  

You like Acetone..... 😳  I'm still sort of expecting a "just kidding" post.

@byron Acetone is nasty, powerful, stinky, and bad for human life in general. I hope he is using a negative air pressure and extraction fan type of setup.

I also have the Prusa textured powder coat bed.  I don't need to put anything on it and if I show patience (rarely) on cooling the part will just be setting there to pick up.  It will be totally release.  I use the Acetone for post processing in all kinds of ways!

I don't go sniffing it all day, but no... I don't use a hood. 

It's one of those childhood memories.  Fond one.  My Grandmother removed her fingernail polish every night.  It's what all southern ladies did.  She lived well into her nineties and didn't die from anything related to wiping her fingers in it every night!  My Mother did as well... until someone said you have to use this non-toxic stuff instead... which didn't work worth a tinker's damn.  Thank you Big Brother for saving us. 🙄 

I guess I shouldn't talk about my affinity for JP-8.

This falls under... As an attempt, that I wouldn't recommend.

To pan sensors around on a robot, I wanted to try something different instead of using a servo. 

  • These micro steppers, even with an A4988 driver is cheaper than a micro servo. 
  • The stepper is smaller than a micro servo
  • The stepper will also take less overhead from the ESP8266 MPU I'm using.
  • The stepper is dead silent.  The DIY gearing... not so much!
  • It can turn +/- 180 degrees or even more if desired.  
  • It can be accelerated/decelerated easily.
TurretDrive

Video at normal speed - A little noisy.  This is with no lubricant.  I found that if I let things rub... they tend to self smooth.  😉 

 

Here's the thing using slow-motion 8x.  It sounds like a boat hauling up a chain anchor.

@inq Very cool. I wonder though how it will behave with a load?

For my Inqling Jr, self-balancing robot, I wanted to add a sort-of training wheels while I program it for sight and then how to balance.  For that I wanted a light-weight castoring tail-wheel.  I want it lightweight so it doesn't add too much rotation inertia to the robot.  And for S&G I thought I'd try to print one.  

Bearings

The upper piece with the bolt will be the main wheel bearing for the rotating wheel.  It still needs to loosen up.  I've connected the bolt to a drill to do some high-speed smoothing of the races.  I wouldn't say that it spins freely yet, but I think a wheel on it will roll.  😆  I think it will get better with some more smoothing and then add some lubricant.

The lower piece, not assembled yet, will be the castoring piece... where the races are side-to-side platter bearing versus more typical bearing above.  

In both units, I use air-soft competition pellet B-Bs.  They're 5.95 mm in diameter.  I got a 3000 count bag a long time ago and they'll last me another ten life-times at the rate I use them.  

VBR,

Inq
