Cura 14.01

Recommended Posts

Cura v14.01 / Ultimaker2

Hello

I am not quite clear whether the following things are already known, so please forgive me.

Print-Canceling:

1.) After a print canceling sometimes the material feed-stepper is not switched off. The motor does not move, but he holding the last position. The other engines are completely OFF.

Is that intentional?

2.) Even after a print-cancel. The filament is very far removed from the heating chamber. I know in older versions Cura it was worse.

Why is this needed at all?

For this second thing I've found so far a good solution. After a print cancel go in a few seconds to:

MAINTENANCE> ADVANCED> Move material> ;and then turn the wheel until the filament thread comes back from the nozzle. This effectively Prevents clogging.

My explanation / Guess:

After a print abort, the machine pulls the filament thread from the heating chamber, which can lead to massive problems with the next material transport. The Older FirmWare of the UM2 pulled the filament back maybe >15 centimeters. The current version of Cura makes it still maybe >5 centimeters. It is intended to prevent probably burn, but that's nonsense, because the small rear fan provides effective and fast cooling when the chamber is no more heated.

3) Another case concerns the initial setup after a factory reset, or immediately during the first use of the machine:

If the filament successfully threaded into the extruder system, the drive rotates a few extra rounds very fast and pushes a lot of material out. This should happen more slowly, because sometimes it leads to the digging of the knurled wheel. Since it seems to be more appropriate thread the material completely manually.

A small addition:

And while the printing is started, the material feeder should begin slowly to move the first material after heating. This could protect the filament from having the knurled wheel digs. Currently it goes very quickly, perhaps too quickly for the starting process.

And anyway, why the machine does not start in the left front corner to print? This may protect the object to be printed, so that the first portions of the thread do not come into the area to be printed.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
