Some excellent progress has been made in the last two days in the quest to get a XYZprinting Da Vinci 1.0 printer to print NinjaFlex filament.

Two different filament guides for Ninjaflex have been trialed with differing success.
One made from heatshrink was promising initially but has failed to be robust. The second, using a 3D printed component from Thingiverse has increased print time but is difficult to install.

Details of the results can be followed here.
Some degree of success has been achieved with printing Ninjaflex with a Da Vinci 1.0 printer. Today, three test prints were made; one is of marginal quality but it was the first. The second for the day, turned out very well and the final print was OK. Each of the prints had differing infill settings so there is still some refining to do.

Can flexible filaments such as Ninjaflex or TPE be used with a stock Da Vinci 3D printer? Probably.
Preliminary testing and multiple trials indicate that it is possible to use a stock Da Vinci extruder with minimal modifications to print this unique material. Additionally, it may be possible to use a stock firmware (1.1.J) and XYZware to make objects printed from Ninjaflex.
Successful progress and encountered pitfalls are being documented as this journey unfolds.
