Polycarbonate at 270-300 C on UM2+ (extrusion upgrade kit)?


Recommended Posts

Posted · Polycarbonate at 270-300 C on UM2+ (extrusion upgrade kit)?

Hi folks,

I have recently upgraded my UM2 with the extrusion upgrade kit.

Something I have always wanted to do was to print in polycarbonate at higher temperatures. I have successfully done the Labern fan shroud in PC at 260 degrees and it works great (no warping), but for stronger parts I believe I need higher temperatures.

Others have done higher temperatures, but I want to confirm current knowledge/wisdom.

From my reading, the new TFM coupler is much better at high temperature, and I think the TinkerGnome firmware will let me set the nozzle temperature up to 300 degrees, so my questions are these:

1) Are my assumptions above correct?

2) Is TinkerGnome's firmware now stable and working with UM2+ (and upgrade kit)?

2) Should I also get an I2K, or is that no longer necessary?

3) If so, should I also get a shorter TFM so the spacer still works?

4) Would I need anything else?

5) Should I be concerned with anything else?

6) Any tips on getting PC to stick? (I used crazy glue on kapton tape and that worked sorta okay but still warped a bit.)

Any insights would be much appreciated. Thanks very much.

        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
