How to ground your MH721 cutter

[GL Motor 0]

Yes I'm new at the site But have had my MH721 cutter for over 2 yrs now with really no issue I just read the manual and figured out as I went.

Last friday my cutter arm would not lift while making banners after looking all over the internet I went to us cutter for answers and found the forum I then read the post and did the recommended troubleshooting and contacted USCutter and ordered a z chip I put it in and tried it and it worked twice so I turned off and moved to it norm location and now it won't lift again I checked all wiring and the chip (?) It must be the mother board I will contact USCutter on Monday and see what I can do.

BUT, I saw all the request on how to change chips and ground so sence Mine is tore apart I took photos and here they are for all to use maybe this will explain it easier for others.......
