Carriage not lifting/lowering

Recommended Posts

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.

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).

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.
