Merry Christmas to me!
packmule:
Congratulations on your printer.
I bought the same one and its proved invaluable in the workshop, from making replacement gears to holdown clamps. It has also got me to use Fusion 360,something i had no experience of but a lot of playing around and the help of youtube and we're now producing parts i would only have dreamed of making.

Congratulation with your Prusa 3D Printer :cartwheel:
I got mine in 2019 and it has been a experience mixed with success :whoohoo: and despair :'( :cussing:
Mine has been upgraded (MMU2) and slightly modified (added LED's to show Filament Status).
Most of the time it's not in use - but it do participate in Production (making Custom Washer/Spacers in PETG).
It worked almost perfect after assembly and very well a few days later after some adjustments - but some 6-7 weeks later it went downhill and got more and Printed more and more random .... :cussing:
First discovered Mistake - I had only turned one of the screw in till it touched during adjustment off the X-Belt and forgot to come back and tightnig it fully - IE. then reason I got more and more imprecise Prints :facepalm:
The Printer was ordered with the MMU2 but that had longer delivery time, so when I recieved this - I had to disassemble the E-Axis - in order to modify it for the MMU2. This revealed my other mishap - again bad memory - another Screw / Nut - that now was loose :facepalm: :facepalm: :facepalm:
As the last one explained why it got more and more problems with the Filament Feed - I thought that all my problems where a thing of the past - and they where for several months :)
But Filament Feed and Layer Zero problems came back with a Vengance :'( :Mad: - to the point off giving up -> six months off disgust + not using ......
When I 'came back' - I started by searching the Prusa - User Board. Here I found out about the Status LED additions. So I added a Red LED to the Printinghead to show the Filament Status and a Green LED to the MMU2. Both work Perfect - but the Colors should have been swapped, as the Red is on when All is Good and the Green lights up when I got a Problem :facepalm2:
With the LED in place, it was easy to Adjust the Tension on the Filament on the E-Axis - so I haven't had any of those problems since .... Knock on Wood etc.
Only real problem left is Layer Zero - and no Alcohol Wipe has solved that ....
But having the Printer print the whole Layer and just stopping here if it's bad - remove Layer Zero and Start from Start again usually works very well (a few times I have needed to do it more than once for the same print). The times where it has done Production Runs, I only had to do this first time and then it will do as many times as I need without any problems - they only reapear when the Printer hasn't been use for a while or I'm printion on an 'unused part of the plate'.
I have lost the 'Glue-Stick' long time ago - and often wondered if it would have solved these situations as no matter how much I rub the Plate with Alcohol (IsoPropyl) it doesn't make a difference - but printing a 'Lost Layer Zero' do ....
The latest Slicer rev. 2.5 has solved many of the other small niggles I had - except now I get a high number of tiny strings - I didn't have before .... Let's see what Revision 2.6 brings ;D

You must have been a very good boy this year. How about an engineer and fireman for the A3? Whatever, I'm sure you'll have fun with it.
crueby:
Per, thats why I've stuck with the PLA filament, it doesn't need anything special to adhere to the plate, and seems like a good all-round plastic. Unless there is a need for the properties of one of the others, I'll stay with that one. Fully understand that if there is a need for another, food-safe or extra strength or something, its well worth the extra steps.
:cheers:

Thanks, everyone!
Yes, I'm quite excited about it! Per, sorry to hear of all your problems. But as with any new tool, there's always a learning curve, and I think I'm up for it. Guess we'll see!
And I believe an MMU2S is in my future too, though not for a while. I figured I'd get to know the base machine and work with it for a while before I added the multi-color complications.
Dave, you have a lot of options available to you at work! That's pretty cool. I looked at SLA but the smell and messing with the resin just put me off. I figure FDM will do me for a while :)
Ron, good suggestions! Now I need to see if Thingiverse has the appropriate models for an engineer and a fireman!
