Hey @robotprom, thanks for reaching out and sorry for the trouble. It sounds like you need to replace one of your filament switches and your homing switch. If you send us your shipping address and order confirmation (i.e. receipt or order number if from our store), we can send you these ASAP. When you receive the switches, please follow [http://mm3d.co/p2replace-switch|these installation instructions]. Thanks for your patience!
