Not sure if you guys are going to believe me but i have a MH1351 and iv had it for a couple of months and have been cutting alot of vinyl with it and it has been cutting good, the only thing is when it cuts a long 24" horizontal line it would zig zag, just barly. The only way a couple of months ago I could get it to cut is to set the blade out an 1/8th inch and it would do fine, well I jumped on here today and you guys were talking about the blade holder being off the track.......Sure enough it was off I cant believe it worked so well. Man the paint on the side of the track is gone as well.....lol, these machines have to be built well if you can run it being all messed up.....Thanks guys
Happy cutting!!!!
