r/QIDIQ2

The Qidi Q2 specs say the chamber can go up to 65°C. But is it a good idea to actually run it that hot? Can it prematurely wear out parts of the printer?

Has anyone encountered issues from prolonged use of the Q2 at chamber temperatures of 60°C or over? If so, which problems were they?

Background:

I'm new to enclosed printers. My Q2 has stock 0.4mm nozzle.

I ran basic calibrations on some generic ASA filament. The results suggested 265°C nozzle temperature, 0.92 flow ratio, max volumetric speed 20mm3/s.

Today attempted my first large model, this desiccant holder for the Qidibox: https://www.printables.com/model/1636883-qidi-box-desiccant-vessel-qidi-q2-qidi-plus-4-qidi . Stock PEI plate, washed about 5 prints ago. The intervening prints were small ASA parts that succeeded and I minimised finger contact to the bed when removing them. Sprayed two squirts of 3dLac+ onto the plate before the big print. Set outer brim to 6mm with 0.25mm gap. Chamber temperature set to 55°C and bed to 90°C for all layers (Orca generic ASA defaults, IIRC).

Unfortunately, the print turned into spaghetti after about 10mm. So I'm after tips for next attempt on this part, and for other big ASA prints.

I will definitely reduce the brim gap to 0 next time, and wash the plate right before printing. Probably also run chamber at 60 or 65°C.

Hello.

I was clearing a jam in my Qidi box hub and lost the spring that pushes on the filament sensor inside the hub.

Does anyone know the dimensions or of a replacement for the spring?

Here is a picture of the location for the spring.
