Creative Tools has several ongoing support cases derived from faulty Flashforge Guider II and Flashforge Creator 3 mother boards. This is caused by a recent firmware update.
A while ago, we warned our customers about updating firmware on the 3D printer Guider II. The warning still applies, and now the warning also includes Creator 3.
DO NOT UPDATE GUIDER II OR CREATOR 3 FIRMWARE! Do not accept firmware update on the 3D printer’s display. Ignore update for now and await further information.
