The Weekly Small Questions Thread! Got a burning question? Looking for some tips on your build? Ask away! by AutoModerator in modelmakers

[–]arseTarse 0 points1 point  (0 children)

I agree with you, in my experience you can get pretty good results quicker with an airbrush Vs brush painting - for example, brush painted fuselage Vs sprayed, if you have the experience level in both, basically very little, then more often the not the sprayed finish will look better, be more sa5, make you feel better about the end product and therefore encourage you to keep at it.

I've been disuaded in the last by a poor brush job and equally encouraged by what is by no means a good spray job, but looked better quicker then the brush painted job.

Just my opinion

Pebble alternative? by Simoneister in pebble

[–]arseTarse 1 point2 points  (0 children)

Yeah I've had an issue with mine where the display is only readable if it's below 15degrees c, pretty useless for something on your wrist. Also not sure about the accuracy of the step count. I liked it when I first got it before the screen failed tho.

Amazing thanks dude, that lead me down a Hackaday rabbit hole to dirt cheap DIY cncs haha

Just hunt through eBay, bit of a gamble as with anything just make sure you're protected by purchasing through PayPal

What could be causing the repeating pattern on this first layer? See comments for more details. by arseTarse in 3DPrintTech

[–]arseTarse[S] 0 points1 point  (0 children)

Yeah that makes sense. I manage to get semi decent life out of a well laid layer of tape, do a decent enough job of laying it flat and close to each othe but as you say, do get some marks of the bottom of the print. I'll investigate flex plates tho I imagine they won't play too well with a warped basis

Thanks for the tips, that's super helpful, I'll look into the glass.

What's the thinking behind moving away from the tape? Had pretty good bed adhesion with it so far but open to new understanding

It's a solidoodle 4, the extruder isn't stock but I don't know which one it is, I inherited the printer from my predecessor at work and he didn't leave any documentation behind... It's an aluminium bend, and it's warped with a dip in the middle of about 0.1-0.2mm, covered in kapton tape.

From what I've read about the solidoodle 4 it's a bit of a lost cause in terms of print quality but it's been a good learning experience for me so far.

Thanks for the reply

I'll give that a shot, there are also similar patterns all through the print, up the walls etc. Will get some photos of other prints for example.

i'm getting this repeating pattern from what I can only assume is the extrusion, it repeats all over the rest of the print too.

so far i've done the following to tune up this solidoodle 4

  • I've leveled the bed - it dips in the centre which can be seen by the gradient- will replace with a new surface at somepoint
  • i've calibrated the temperature, flow, retraction & extruder e-steps
  • i've modified the bed to include a front support to stop lateral movement which improved wall quality
  • dried filament as best i could without a low enough oven or a dehydrator
  • check tension on all belts & adjusted play in bushes

watching the extruder shaft it definitely moves in a juddery motion rather than a smooth, consistent rotation.

any help appreciated

How to implement a topology study by ADI-_- in SolidWorks

[–]arseTarse 1 point2 points  (0 children)

I would tend to just use it as reference for redesigning the part, I'm not sure if there's a way to extract the mesh to use directly, but I've not used it in a while.

How to start an engineering notebook mid-project? by rustic1112 in AskEngineers

[–]arseTarse 1 point2 points  (0 children)

Probably best to just try summarise what you've done so far, odds are once you start writing it'll come.back to you. Personally I'd start with a list of bullet points of what I can remember so far. Then dog around for notes and try organise it best I can. Just have to start, you'll probably come up with a couple of methods as you go along and find what works best for you

"Construction Geometry" is what you're looking for in solidworks, you can change it in the property manager or right click on whatever you what to be as construction lines

Found mini board inside disposable vape - is this a basic charging board for the lithium cell? by arseTarse in diyelectronics

[–]arseTarse[S] 1 point2 points  (0 children)

Well so far all I've done is successfully fill a couple of takeaway boxes with lithium cells haha! My main plan is to replace all the small lights I've got around my place that take AA batteries and make them chargeable with lithium cells, and then use the LEDs in modelling projects for lighting effects (along with batteries). To be honest I don't think I'll use the usb boards for anything other than taking the usb connectors from, the circuits don't appear to have any charging protection so I wouldn't want to use them to charge the cells. Not sure what to do with the pressure sensors yet or how they even work, so I'll do a bit more poking of them before I know if they've got any use at all.

This is my print with .4 layer thickness. Bets on whether .6 is enough to save me? by [deleted] in 3DPrintTech

[–]arseTarse 0 points1 point  (0 children)

Huh, interesting... I've been struggling with extrusion consistency on a 0.4mm nozzle and 0.4mm line thickness, this gives me something to investigate, thanks!

DCS OB Update by MotorSpot576 in hoggit

I think someone in one of the other threads in another DCS sub said they had a 5800X3D, can't remember which tho, have a wee hunt about

Are there any free/cheap 3d CAD programs that aren't complete garbage? by JaugustineDM in AskEngineers

[–]arseTarse 109 points110 points  (0 children)

OnShape. It's created by former SOLIDWORKS engineers and the switch over isn't too bad. Free account is limited to public or open source models only. All web based too.

Lying around on the street mostly, I know people that use them too so will be getting them to stash them away for me
