3D Modelling and Printing. Mostly on Topic.

Recommended Posts

Here we have a colour fail. I have the only SDM case in the world that looks like it has been sat near a window for 20 years yellowing.

This is now a $20 reel of PLA I can't use for anything. It was also extremely abrasive and has worn the sacrificial filament guide I have in place and it needed a temp of 220 to extrude properly.

 

Ordered another lighter colour filament.

 

Scribbles on paper are the math from recalibrating my extruder.

 

I have learned so much from doing this, it's been excellent fun.

LOL, looks like a perfect match to most of my 800 era stuff 🤣

 

It is quite a learning experience.

thats the spirit - mistakes are a great way to learn fast & 3d printing isnt an exact science to say the least!! :?

1010 after an hour... 5 more hours to go for the main body. Still need front panel, metal strip and back panel.

I am having lots of problems getting a good 810 print. all the little veins on the back keep popping off the print bed, there is a LOT of tweaking and wastage happening :(

 

In the mean time, the devil makes work for idle hands...

if the veins pop off try a single attached line after them on the bed, it will come right off when done... you  might have to do light  sanding when finishing it up...

I've tried that, I think my ABL is failing and catching the model at random points in the print. I am now printing with a 1mm z-hop which is ridiculous but it does seem to be working. I have some fine stringing, it looks like spiders are nesting but I'm over half way through with no disasters so far. 

 

I need to look into getting another ABL.

Yeah. I don’t have ABL, but I see this when my bed isn’t leveled properly. 

 

So, I’d say you are on the right track. 

 

It also seems some filaments are more prone to this than others. 

 

Try another filament from a different manufacturer. If that helps, cross that manufacturer off your list.

810 case still has 1.5 hours to go...

@mytek the confused face made me laugh! 

I'm sitting here drawing 3d printable atari cart designs while I wait for the printer to finish.

Same problem is happening with the 551. Some things are just hard to print with FDM printers. 

 

I now have a box full of waste, test and failed prints, amazing how much PLA gets wasted doing this stuff.

I took that idea and added a frame to the SDM screen hole, it's not what you were trying to suggest but thanks for the inspiration!

I've done the same thing to the 810. The 551 is printing now and looks much more reliably printable.

I hate to do this to you, but because of how good you are getting with these SDrive-MAX cases, I was wondering if you would also consider creating a case for the SIO2MIDI sometime down the road? It's just crying out for a suit to cover its bareness ;) .

I could send you a couple of blank PCBs and one assembled unit if you are the least bit interested. Send me a PM if you'd like to discuss this.

 

Keep up the great work... it's absolutely amazing!!!

Well the border around the window seems to have done the trick.

The grey I have is depressingly dark. I've ordered a lighter one.

@mytek yes I'm interested in making a case for the SIO2MIDI, I have every intention of replacing the midi in my XEL with your updated board and the midi port extension at some point so helping out with that would be cool! 

 

I'll shoot you a PM

it wouldnt be too difficult to rescale/tweak the design to create replacement casings for the real devices! :)

If it wasn't chopped up into little pieces where aren't a lot of common printers that could print a full size one.  There are already Kryoflux, 2.5"HDD and SDCard reader cases with Atari styling on Thingyverse.

So, just the busy light then ;)

 IMG_2018.thumb.jpeg.3e485523fd1aa008e508e1ae12e89d66.jpeg

 

I thought the size of the led would be too small for these... however if I made the case a little larger I could fit a power and busy led and an on/off switch...

the XF? just a busy light there... but you could add a power light for the other devices that will be nestled inside.

 

There are some very tiny pin dot led's both round and rectangular but if putting a hole there is a bother, I was just thinking a fake impression would set things off nicely. How far do you want to take it? You could make the disk latch an on off switch or reset switch or  ....  well you get what I'm saying.

Yeah I get it, I have similar thoughts, but truth is, how many people want to put in that amount of effort for what is essentially a plastic case. I could maybe make some super cases as a limited edition or something

Well... After a weekend of failed prints, 10 in total I finally got the settings for the new grey PLA dialed in.

Here's the old grey and the new grey

Doesn't seem like it was worth the effort tbh

that's looking way better tbh, and it may help with future production, each time you dial it in you are getting a range to work from in the future, when you have a new reel you can thumb to that section in your notebook or spreadsheet and select from that range... then choose your test print item and refine that setting before running off the actual full scale items from that filament... this will save you a great deal in the future.
