We purchased Potterware about a year ago and have no problems. Our printer setting in 4.0 was set to Potterbot Duet Standard even though we own a Potterbot 9 Standard. In the latest update of Potterware the Duet version is now gone. When we switch to Potterbot 9 we have issues with the extrusion speed. The clay extrudes too slowly and causes the print to fail. Any help would be much appreciated.
