MZ SKEETER 4,709 Posted April 2, 2011 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 Brad read below the product? Do you have your cutter grounded? If you don't, you may get the same problem again http://www.uscutter.com/Z-AXIS-CHIP_p_1650.html 1 Share this post Link to post Share on other sites

Is this a new cutter? 1 Share this post Link to post Share on other sites
mwmoo9 0 Posted April 2, 2011 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 Brad Share this post Link to post Share on other sites
MZ SKEETER 4,709 Posted April 2, 2011 did you ever ground the cutter? Contact tech support on Monday, put a support ticket in. Might be the motherboard. 1 Share this post Link to post Share on other sites
MrMopar64 47 Posted April 2, 2011 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 MM64 1 Share this post Link to post Share on other sites
mwmoo9 0 Posted April 3, 2011 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! Brad Share this post Link to post Share on other sites

Brad 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 MM64 1 Share this post Link to post Share on other sites
