slice&dice 2,211 Posted January 12 Buenos dias. Your problem is related to a thing called the Z-Chip (which is on the motherboard, and controls the up/down movement of the blade). That internal part is easily 'zapped' by static electric discharge (the MH is infamous for this). Share this post Link to post Share on other sites
darcshadow 1,369 Posted January 12 The older versions of the MH the z-chip is in a socket and can easily be replaced. The newer versions, it is soldered to the board, can still be replaced, but will require some soldering skills. Share this post Link to post Share on other sites
slice&dice 2,211 Posted January 12 Obtaining the Z-Chip is a challenge. USCUTTER no longer offers them in their "Replacement Parts" bin. Share this post Link to post Share on other sites
darcshadow 1,369 Posted January 12 I believe it is a basic op-amp so if you look up the numbers on the chip you should be able to find it, or find one from a different manufacture that has the same electrical capabilities and pinout. Share this post Link to post Share on other sites
Angelbtnh 0 Posted January 12 Agradezco de su ayuda veré si lo puedo conseguir donde me recomiendan buscar el z-chip Share this post Link to post Share on other sites
darcshadow 1,369 Posted January 12 I just checked, the photo on USCutter's page that shows the Z-Chip. In the photo it is a LM324N, I would assume the photo is an actual photo of the chip but I'd double check the numbers on the chip in your machine before doing anything. Assuming LM324N is correct, as I suspected it is a basic op amp and you can buy the chip for about 30 cents from various electronic supply shops. Shipping will be the highest cost unless you have a store local that carries misc. chips. 1 Share this post Link to post Share on other sites
slice&dice 2,211 Posted January 13 I recall Forum member dakotagrafx had a limited supply of 'em, back in 2014, but he may still have one lying around. https://www.uscutter.com/Z-Axis-Carriage-Chip-for-MH-Series-Cutter It's been a while since I noticed any "local electronic supply shops" -- the last of those, RadioShack, is gone like the dodo bird.

slice&dice 2,211 Posted January 13 It would be worth buying 5,000 at once from digikey, their per-unit price drops to just 13 cents each. Share this post Link to post Share on other sites
