MH 721 Help Blade not going down.

[Moes Decalz 0]

I have a MH 721, have owned it for a couple years.. the blade stopped going down to cut on the vinyl... i reviewed other issues on here sounded like the Z chip.. bought one, installed.. no luck.. called tech support.. they said turn on the machne and what does the blade do.. i said nothing. doesnt go up and down. he said its teh carriage.. i ordered that just installed it.. guess what still nothing.. any ideas what it would be?.. im guessing next they will say motherboard.. what else is there to replace right.. any help would be appreciated!!.. I have a huge job to do this weekend.. but it doesnt like it will happen.. very frustrated!!! Thanks in advance!

Maybe a loose wire to the electromagnet?

Maybe a loose wire to the electromagnet?

I would have thought the new carriage would have cured the loose wire on the selenoid

Bad USB or serial cable?

I can test the carriage from the wires on the motherboard.. i unplug it and test the 2 white wires going up to the carriage witha  9 volt battery and it jumps up and down.. so im guessing  its the motherboard....

I did the 9 volt test on the old carriage before i called tech support and it moved up and down.. i told tech support that but they still said it could be the carriage.. $25.00 +$9.00.. says i shouldve just ordered  the motherboard.. knew it. hey its only $$$ right

I have same the same symptoms as you described in 2013 ...
