haumana 1,220 Posted November 25, 2023 when the machine is off, is the blade carriage in the "up" position or in the "down" position (resting on the cutting strip)? Share this post Link to post Share on other sites
darcshadow 1,626 Posted November 27, 2023 Sounds like your Z-chip is dead. The z-chip is a simple op-amp that provides power to the solenoid to raise/lower the blade. Search the forums for blown z-chip. There are discussions on how to replace the chip as well as using a 9V battery to verify the solenoid is good. Share this post Link to post Share on other sites
