Product Recall Notice



Due to product defects of the Melzi boards, the previous batch of boards (From 12/2013 to 03/2014) has problems that can cause the printers to not work correctly on some 3D printers.  The main problems are the heatbed and extruder thermistors are using resistors that are 10kohms instead of 4.7Kohms. Secondly, The MOSFTEs for the heatbed used the 10N06 which can only take 10A current (now changed to the 35N06).

Please note, the Melzi boards currently from are only recommended to work with 12V, so please do not use 24V on these boards.
