Recommended Posts

We have a MH871 and the the blade will stay up and won't go down. Is there anyone that would know what would cause this?

thanks a lot

Someone else who has replaced one will have to chime in, Have you made sure the blade holder screw is rubbing against the carriage head? Is this a new cutter?

no its not hitting. the machine is a year old. we have only used it a few times. the last time we used it we static zapped it. we changed the z axis chip. now the cutter stays up. but before is stayed down.

thanks for the help

did you ever ground the cutter? Contact tech support on Monday, put a support ticket in. Might be the motherboard.

the chip should have a notch on one end that is the end #1 pin is on... and yes it has to go in with the notch same as the old one

and this is where the trouble lies. we where have a dumb moment and didn't pay attention to how the old one went in. does it face toward the center of the fan or away from the center?

thanks for all the help guys!

Look at this pix... http://www.uscutter.com/zoomify.asp?catalogid=385ℑ=assets/images/gjqb.jpg

It looks like all the notches face the fan...

Hope this fixes your prob... The only thing might be ...if you put it in wrong it may be no good

Got the Z axis chip installed correct, the notch points to the middle of the fan. The pic helped a bunch. Everything is working right now. Thanks a bunch.
