Im posting this to warn you about the possible problems you could have when printing large components with luzbot Taz 5. Yesterday, i’ve printed a 750g part that occupied almost all the area avaible on the bed. The print went horribly wrong as you can see on picture. I have printed more than 50 parts with luzbot so im experienced with it and i never had thos problems with smaller parts. The problem is that the printer cannot stop by himself and just keep flowing some filament.
That’s typical with any printer. That’s why it isn’t recommended to leave the printer unattended. Its at your own risk if you choose to not watch it.

I completely agree with keebie81
BUT
When I have a print that will be running for more than about 8 hours, I find it difficult to keep an eye on it.
SO
I set up a camera near my printer, so I can look at it from time to time.
I always check my prints about every 30 minutes or so.
I try also to use filament that I can rely on, where it’s diameter seems consistent.
I never build a large object with the last part of a roll of filament - sometimes the very end of the filament is squished
and will jam in the extruder.
Things happen.
Don’t be too quick to blame the printer.

I hope this comment helps in some manner.
Hi Alex,
We have a couple TAZ 5 and 6 models, from the photo it looks like it failed to laminate the first few layers?.. And yes, they don’t stop if somethings wrong.
But to be fair we’ve never had an issue with large prints with any of them, we have had a couple of issues with some filament suppliers material not working correctly at the stated tempratures and we get the first few layers not laminating (similar spagetti to what you have in your photo) - but these were all solved by either avoid cheep filament or tweaking bed/nozzle temps and/or adding glue stick to the bed to get good adhesion.
Couple of options for you:
- Look at the first layer lamination, not sure what material/temp etc you used but try tweeking that and keeping an eye on the first few mm of the print (the photo one looks like it didn’t even stick to the bed on the first layer?).
- Try glue stick on the bed or tweaking the bed temp for the first few layers to get that first good stick of the base layers.
- We setup ours with cameras so we can keep an eye on them (Raspberry Pi / Motioneye - cheap, simple and easy to setup a basic set - let us know if you want some help I think we might have a few of these laying around), we monitor printers pretty much round the clock and never leave one more than a few hours without a glance - We then went a little overboard tweaked the motion detection to look around the printer and anything in certain areas of the camera view would set off the motion trigger - this allowed us to see if anything falls of the print bed or is moved into the area of the printer that might effect it - also a ‘nice-to-have’ to be able to give customers a video of their print (the motion eye also does cool timelaspe for you!).
Hope this helps
Mi.
