Re: Marlin 1.1.9 upstream released

Are you making any changes to the Marlin source outside of Configuration.h and Configuration_adv.h?

Re: Stepper Motors Not Working

You will need to flash the firmware after installing a new Rambo.

Are the Z motors geared?
Nope! The benefit of the Z motors being geared was to prevent a drop of the X axis when the unit was powered off. We added a Z brake board to accomplish the same goal.
Thanks.

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.

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...
