Re: Catastrophic failure

Look to see if your heat sink for the Z driver is missing or fell off on the control board. The driver can overheat and reduce/cut power to the driver and make the nozzle drag across the part sometimes and break the extruder. That's actually kind of interesting. I just put my printer in an enclosur...

Re: Catastrophic failure

I think that it touched the bed because the body broke and everything tilted forward and down.

But either way the extruder assembly needs significant repairs.

Catastrophic failure

Last night I start a print and, when I get up this morning to check on it, I find this... 20160605_080629.jpg The bed, during the print, shifted way off, the nozzle burned into the PEI sheet, the main body of the print head snapped at the screws where the extruder mounts, and the screen shows mintem...

Re: Taz 5 ABS cracking even with cat guard. Next steps?

No, acrylic hobby paint will also chemically bond. It doesn't hurt to rough up the surface a bit for mechanical adhesion after too though. Still not sure of the type of paint I am going to use yet but I'll keep that in mind. It's going to be a full body suit so ease of application and cost will be ...

Re: Taz 5 ABS cracking even with cat guard. Next steps?

In total its about a 48-50 hour print. I'm making costume pieces so I'm really trying to get as much smoothness/detail as possible to reduce sanding/rework later. The stock profiles for the fine prints use 0.16mm layer height. Use thicker layers and look into acetone vapor polishing. I was kind of ...

Re: Taz 5 ABS cracking even with cat guard. Next steps?

Thanks for all the recommendations, folks. My print is now well past the point where I've been getting splits. I raised my temp by 10 degrees and turned off the fans. A picture with results is below. I now feel like this is dialed in enough to continue my project which will take a couple months of s...

Re: Taz 5 ABS cracking even with cat guard. Next steps?

Steps that fixed it for me 1. Build an enclosure (which you've done) 2. Turn off your part cooling fan. If the part is larger, you don't need it. 3. Bump the nozzle temperature up to 250C (Assuming you're using Lulzbot ABS) 4. Print with a brim to hold it to the bed better. On huuuuuge parts you're...

Re: Taz 5 ABS cracking even with cat guard. Next steps?

They're display pieces until you're on a convention floor with 80k of your closest friends getting bumped/shoved and everyone wants a picture and/or generally aren't careful. I'd be fine using PLA if the parts were thicker. But, because they're relatively thin, I'd rather not deal with the snapping...

Re: Taz 5 ABS cracking even with cat guard. Next steps?

Also if that is a 24hr print you are using super fine layer heights which aren't necessarily needed for an object of that scale. In total its about a 48-50 hour print. I'm making costume pieces so I'm really trying to get as much smoothness/detail as possible to reduce sanding/rework later. The sto...
