Picked up a Robo 3D 1 + on a boxing day sale. Been printing some small items with varied success. Having problems with bed adhesion on a lot of things. The recommended Aqua Net hair spray isn't available in most stores and online it is $48 CDN +. Tried a few other sprays and gells with limited success using PLA. Tried some TPE90A flexible, total disaster and it is one of the stiffer TPE/TPU formulations.
