I doubt that you can bypass the Chip on the Ekocycle, since some of you may have a Cube 2, the trick is:

Install a Cube Cartridge as usual in its slot but feed a bulk roll into the head of the printer.

Once the print had started, hit the stop button and the printer should ask you if you want to confirm that you want to stop the print (the printer should still be printing). At this point, you will want to pull the Cube Filament Cartridge out of the slot so that the IC on the cartridge is no longer touching the contacts on the printer. This will prevent the filament level decreasing on your cartridge. The missing cartridge timeout will not begin as long as the screen stays on the "are you sure?" Screen (paraphrasing, don't know the exact wording on the screen).

The bad, you can see your print progress and its a little extra work. The good, you can use bulk filament.

From what I recall, cube filament is 1.7mm (1.65mm)while the industry standard is 1.75mm

On the cube 2, you can remove the print head cover via the two screws on top. Inside there will be a nut (towards the lower side of the front of the print head, should be facing left when you look at the printer from the front). If you loosen this nut you can adjust the tension on the feed stepper in order to allow for the larger filament.

This is probably a little out of place on this thread, but hopefully it helps someone. I use "JustPLA" and "JustABS" from
Amazon, it seems to be decent, but I wouldn't say it's flawless. My feed has still jammed with these (albeit rarely)
