yamahajps 0 Posted August 21, 2021 Hello i have a bridge pro 720. It does everything except move the blade up/down leaving cuts all over. It does move freely up/down by hand whether its on or off. I can get it to go down by putting power directly to the solenoid so im assuming solenoid is good. What should i do from here? Ive reached the extent of the slight knowledge of electronics i have lol. Please help. Or let me know if im better of investing a new cutter. Share this post Link to post Share on other sites
slice&dice 2,450 Posted August 21, 2021 The part you'll need is called a Z-Chip. It is on the motherboard. Probably soldered in place. (if you are real lucky, it will be sitting in a socket and can be pulled & swapped without soldering). 1 Share this post Link to post Share on other sites
darcshadow 1,625 Posted August 22, 2021 On the MH cutter it is a simple 741 op-amp chip. Chances are good it's the same on yours, look for a small 8 pin chip that has 741 on it. 1 Share this post Link to post Share on other sites
