Could be the feed belt just needed to loosen up some. Overall though the sander is a great machine for the price. Kudos to Powermatic and their customer service folks! I tried to be to precise and it cost me a new belt. The 4 inch ones roll much better.

Powermatic PM2244 Final Thoughts
"The paint job is wonderful."
I sanded a 14 inch wide board and the results were amazing. The motor adjusts from 0 to 10 fpm. It took maybe 15-20 minutes to have the sander up and running. But light cuts worked fine, no problems. I have found it to be excellent in every regard.
