DIY Cleaning Machine

[Waggy]

I'm currently 3D printing a new basket and trays for my Pearl machine - I printed one last week in PETG material and it worked well at first. I had taken a calibration cube and soaked it in old cleaning fluid for 8 weeks and then measured it, and there was no discernable swelling or shrinkage and the cube seemed mechanically intact. All went well after the cleaning cycles and then onto the drying cycle..... that's when things went awry. The heat was more than I was expecting and the basket and individual trays warped and deformed, I later found out that PETG is rated to 65°C working temperature (PLA = 54°C)

I am now trying to print from nylon (working temperature = +/- 100°C, depending on the specific blend) - but it is extremely difficult to print with, my third attempt is chugging away now while I am at work - hopefully I don't go home to a ball of wool like last time! 

Assuming the heating compartment can't go higher than 100°C.... but not second guessing myself...anyone have any ideas or measured it?

I also have a question on the trays, maybe I'm not seeing the obvious, but how do you use the ones identified with the arrow? they are called 

Basket_for_large_mainplate_and_mainspring.stl
Basket_for_small_mainplate_and_mainspring.stl

I can see the place for the mainplate, but how are you supposed to place the mainspring, you can't uncoil the mainspring to fit around the outer circumference of the tray or else you would damage the inner tight coils. Is the idea that you supposed to lay it on top of the mainplate?

I did read your experience with the basket. I did try to file mine to true it up..but I couldn't find the sweet spot.

I figured I would just bite the bullet and get the Elma components.

 

Thanks

I could only improve it, its still not perfect, the slight bit of wobble left seems to add to the agitation.

you mean your improved 3D oscillation design upgrade

Yes exactly scott, i managed to make it run perfectly true and then reintroduced some calculated wobble using a special formula that i created myself .

Is your special formula called Bovine Excrement ? Hehe.
