Re: Prints Jam Halfway Through - Taz 5

If you are actually having heat creep jams, the jam is happening up in the heat brake. If the filament in that are gets warm, it expands and sticks to the walls. So, the nozzle wouldn't have any effect on that. A heat brake that has a rough interior would make the jamming worse. If you have a 0.5mm ...

Re: Prints Jam Halfway Through - Taz 5

You can use a retraction test from Thingiverse to set your retraction. https://www.thingiverse.com/thing:909901 Print it with 0 retraction then add retraction 0.5mm or 0.1mm per print until stringing is under control. You should be able to get by with 1mm or less, in my experience. What is a pretty ...

Re: Belt driven Z axis as an improvement?

They were looking at geared steppers in the past. That would allow proper resolution for a belted z axis. They have also added a custom relay board that locks the motor position when power is lost. So, the Z isn't going to fall when you power off the machine. The z axis isn't in constant motion so, ...

Re: Prints Jam Halfway Through - Taz 5

If you are printing PLA, it is probably a heat creep jam. The following changes might help. Cool the room the printer is in. Print at a lower nozzle temperature, if possible. Print thicker layers. Reduce retraction to the minimum needed to prevent blobs and stringing. Place a fan that will blow a ge...

Re: Modular Build Plate

Well, maybe I will pass on the modular plate.

If it helps you decide what to do, I have been running a 0.040" thick PEI sheet from CS Hyde on a gMax heated bed for a couple years with no bubbling issues. No issues at all, actually. It seems to be bulletproof.

Re: Modular Build Plate

That's no good. I was just thinking about buying one of the modular plates. I have seen a couple other people complain about the droop.

Re: Filament feed failure

nopick, is that fan 5v or 12v? Do you have a link to that fan? Thanks! Sorry, I didn't see this post. It is a 12V fan powered directly from a wall wart power supply. https://www.amazon.com/gp/product/B01CSU3TCK/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 We have several Taz. Some of them have more t...
