Janta / Pearl Watch Cleaning Machine

[Waggy]

Just arrived, so will let you know in a day or two when I can get the boy to fire up his printer

 

[Waggy]

The tech docs state the nozzle temperature is 240 Max, when we tried this on a test sample we got de-lamination, so my son tried to increase in steps from 240, 250 and 260.... this resulted in exceeding the working temperature of his print head. So, I'm now on the hook for a new high spec fandangled 300 C rated print head for his printer. This watch stuff is an expensive sport!

Which printer is it?  I just need to get a bi-mental heat break for my printer (Ender 3 Pro).  The original heat break let the PTFE tube be too close to the nozzle, which is a problem at higher nozzle temps.

This is my sons printer, so not exactly sure of the model and I know he has done a ton of mods to it. But I remember him saying that I was now on the hook to get him a heat break (I think he mentioned titanium in the context of its conductivity?) and new injection head that could handle 300 oC

Here is the screen from his new high temperature set up... I can see from this it is an Ender3 and he can now get up to 297 C

I printed mine, using PETG under 240c, that's enough though. fyi

What solutions do you use them in? Also how does it hold up to drying temperature?

I use water-based solution and IPA, the drying temperature can uphold around 70 celecious, most of time it take really fast to dry up parts (20 secs).

I recently acquired a Marshall PEERLESS in very good condition without jars. It appears the Pearl/Janta jars will likely fit. Can someone provide info on a source for these jars? Thank you!

Janta jar dimensions.... 3 3/4" X 3 3/4" square X 6 3/8" Tall.  Inside mouth diameter is 3 3/16"

I do not know if Janta will sell them, they can be hard to deal with and the gaskets in the lids

do not completely seal so there is odor and evaporation. The gasket stops about 3/4" from touching

itself. I used plumbers 3" test caps for the lids.

I have a pearl machine and use these Ball jars:

Make sure you get the 'wide mouth'" version and not the standard version.

As you can see from the below they fit well on the machine:

A little tighter on the jar opening, but still goes in no problem with room to spare:

Substitute Ball jar on the left and original Pearl jar on the right:

Also as you can see from my pictures I took @jimzzillareccommendation and use the plumbers 3" test caps which fit the pearl and Ball jars.

Hope this helps

Has anyone removed the basket lid that is attached to the shaft on the Pearl machine, I took off the bolt in the side, but it was still held on - maybe friction??

Before I get to physical with my machine and damage it, can anyone let me know the correct way to do it, thanks

You need to take off the screw at the end of the shaft as well. There’s one that goes into the rod.

Thanks, you probably just saved me $$$$$
