If you are the one putting solvent on the polyprinters come and confess to it or if I have to dig and search to see who it is you will be banned from 3d fab permanently.
this is my only warning…

Why would anyone be putting solvent on or into a hotend?

I can only presume that it was done in an attempt to unjam the extruder… It’s obviously not the right course of action, but people learn solvent can be used to smooth/melt out 3D prints so maybe thought to try it. -shrug-

Lol, Why would anyone operate a Bridgeport while on a hoverboard?

Why go through this much drama about this stuff anymore?
Not forgiving the actions, just pointing out the threats and subsequent negativity often out weight the cost of repair or actions taken against the member.
Sorry the printer got messed up. Thanks for being there to repair or arrange the repair of the printer and running 3D fab.
Hope everyone has a Merry Holiday Season.

No, it needs to be called out and punished if need be.
There’s way too much destruction of equipment at the space due to ignorance or just plain “Don’t care”.

That’s what happens after someone 'fesses up…
Retraining, Temporary Ban, Expulsion… Would depend on the situation and the committee
Primarily retraining …. I don’t really want to ban anyone but if I have to take the time out of my day to do it then yes it’s a ban

RIght. Ignorance, apathy, complacency, or stupidity all need to be addressed. How addressed depends on the level of those adjectives, and/or impact (or potential impact) on other members.
I’ve no idea how big an issue the use of solvent to clean those parts has really caused, but it looks like a lot of work/effort on someone’s part to fix, and there is no reasonably possible way the person responsible didn’t know that some damage had been caused. No one was called out by name here, only put on notice to, at a minimum, contact the chairperson or committee regarding the issue.
At end-of-day it is up to chairperson and/or committee to decide how best to react to stuff like this, not weak suggestions or namby-pamby hand-patting from the non-involved peanut gallery. @engpin is an easy-going, well-intentioned, high-contributing member as well as the chairperson for the committee impacted - I trust his judgment that this particular situation needed to be called out in this manner.

“…the one putting solvent on the polyprinters…” That sounds like an ongoing thing. Are there multiple instances of this happening?
Yes there has…………
Is there a clear sign warning not to use solvents?
We have learned through past sign use at DMS that DMS members can’t read signs. This is why we have training classes.

Do we ever consider retiring the PolyPrinters?
Looking at the pictures of the recent failure again, I realized this is a failure that many low cost 3D FDM Printers wouldn’t suffer. This is because many no longer use 3D printed parts for the carrier of the hot end. Not intending to slam PolyPrinter or their machines, they have been work horses and we’ve had a great relationship with the company over the years to my knowledge. Just, the market has evolved so much.
Now there are many manufactures selling quality out the box FDM printers, one I’ve been watching and will purchase in January is Mingda Magician, link: 3dmingdaofficial.com There are also many others at their price point and build quality as well. Which further highlights the age of the PolyPrinter’s design and build.
I’m not up on the interior discussions around updating tools at DMS. Please don’t take this as a snipe at anyone, as that is not the intent. Just highlighting the opportunity given the state and age of our PolyPrinters and the growth in the Market.

I would imagine the maintenance assistance we get from PolyPrinter is the gold that keeps us coming back. Given 3D printers are a pain to keep alive, having a standardized maintenance contract is probably more valuable than the machines themselves.

What can we do to prevent this from happening again?
I went back to see if there is any mentioning in the training materials of what might happen when using these printers and how to resolve common problems when one encounters them. Nothing like these is mentioned in Dallas Makerspace: Log in to the site
It should cost less to hire someone to add a trouble shooting section in the training material and a few more quiz points than to fix the machines.

DMS doesn’t employ anyone. Everything that is fixed, bought, or taught is done so entirely by volunteers. If you think a troubleshooting section would help, I am sure you could volunteer to add one.
