Yeah they are just setting me up for a big PFO. They factory will probably say something like yeah don't worry about it as it won't affect the performance. Which is true until it pulls in some crud/chips as others pointed out. This will wear the gib strip on the front side and the ways on the back.
My last mill was a G0704 and I had a few issues with it. Grizzly stood behind their product and had excellent customer service. I wanted a bigger mill and was going to get the PM-30MV from Precision Matthews but it was pretty costly to import to Canada. I came across the CX601 at BusyBee Tools and saw one in the store and it looked good and it would cost me about $1000 cdn less. I should have forked out the extra money.
