3d Printers South Africa

I'm on the "3D Printing South Africa" group - I saw someone else had issues, and Bernard did respond last night to try slow the fan down - it didn't work.

I want to try the same print I was having issues with on the other PLA, if its fine - I can then be fairly certain its the PLA and not me :D (the benchie failure I just had might have been the settings I had to try and see how it came out - it looked perfect, but pulled apart as soon as I tried to take it off, in comparison - I tried breaking the sample pla benchie, and its fairly solid)

Found it - thanks, I'll drop him a message directly.

(I actually ordered on the 27th of Nov - so maybe I got a bad patch).

I'm keen to try their SA Filament - seems a great price for basic colours, but - a bit concerned ordering 3x spools and its not great.

That was quick - they've offered to replace it if I don't come right, recommended 220 and 50% fan speed - so going to try that with a benchy.

It seems to only be an issue with the finer prints - the octopus I printed seems fine, the finer prints, like the benchy, and others - it seems brittle.

Anyways, going to order some of the SA Filament PLA from them... so hopefully I'll be back to normal printing in the next week or two.

Awesome!

AMS is really good,

I like the video you posted with the colour changing, definitely need to get some of that

It works well... It printed white, and stayed white for a few hours, the next morning it was the reddish/pink colour.
 
Hi. Don't know if this is the best place to ask it but, I'm looking to by either a laser engraver / cutter or a CNC Router.
Can anyone give me advice?
Which is a good one but not to expensive.

3dprintingstore.co.za , cron craft would be a good starting point

I got one a few weeks ago, with a laser attachment , the laser has been fun, but need to start with the routing stuff now
 
Which one did you get. How strong is the laser?
Can the laser cut thin wood?
 
Struggling to get my VPN up and running again... So in the meantime I can only watch via home-assistant, and hope nothing goes wrong.

Trying out octoprint, so far, so good - no need to move the microsd card back and forth.

What would cause these bubbles? Sometimes happens - other times not - same temps

What material is that? With some materials if the retraction setting is low (and sometimes it needs to be low) the material will heat up in the nozzle and flow out while the nozzle is moving.

Can try increase retraction.

Or reduce the extrusion from 100% to 90 - 95% so that a touch less material is coming out which could reduce buildup in the nozzle and the subsequent purging of material you're seeing there.

Might be another fix depending on the material or your specific printer.
 
Its PLA on a Ender3... just a bit stumped on how it only happens occasionally (twice so far)

Which PLA is it? If it's clear PLA it might still require different settings to regular PLA. Might run cooler, require different retraction settings.

(looks a bit too clear for PLA - you sure?)

Mambawire colour changing... My most recent print which is on going I've dialed down the temp from 200 to 195 to see if it makes a difference.

It does seem to print almost clear though, real pain in the ass trying to see if the bed is level :D

All I have at the moment, going to order some more normal filament on Monday.
 
You can print some temperature towers with new filament to dial in the temperature for a specific batch. Makes a decent difference to your prints.
 
Currently don't have a spot for the printer, and with us starting work again soon, my wife needs her desk back - so I think my next project will be an encloses using the Ikea Lack tables.

Googled them - seems you have to manually setup the temps in Cura, will figure it out and save the gcode for future.
 
Looking for some guidance. I cannot find a supplier for this locally. I came across a video where this was printed.

Modular Dust Collector - Version 0.1 by xjuls

DescriptionHmm... you know so sawdust doesn't clog up the wet/dry vac filter. Parts are attached using threads with an ISO Metric profile of M150x2 (lid), M68x2 (end of the cone) or M48x2 (outtake and intake valve). The Cone and Drum are 150 mm diameter. When assembled it is approx. 300 mm in...

Where in Johannesburg can I get this printed and delivered to me?
How is 3D printing priced and charged?

Turns out the culprit is octoprint... It randomly pauses on prints in spots causing the filament to blob. Weirdly, it only happens every now and then.... I monitored the Pi's resources, and it's barely used.

I see you can change the USB baud rate in the firmware, which helps - just not sure I'm up for the effort.

Had an overnight print last night, just glad it didn't happen.
 
Printed this case for my NVR, took 10 hours ... Its colour changing PVA so should be interesting. Everything came out 100% with octoprint.

Now trying a temp tower - forth attempt. First one fell over at 200 - Second one pulled off at 225. Third one octoprint completely stuffed up, pauses so often I couldn't make out the temps.

Hopefully forth time lucky.

Also hoping to order some new PLA tomorrow.
