So I ran my brand new JPT310HH for the first time today with some 70x35 pine thickessing down to 69x34...easy job for the machine. after about 15meters CLUNK! CLUNK! feed rollers stop. So i start cursing the chinese quality control and begin my investigation. it was the feed roller drive chain, it had run off its gears due to a gross lack of tension. easily fixed.

Now its working as it should however..
perhaps its due to my now sensitivity to the machine, but when tailing out I can feel a inconsistant clunk/knock thru the timber, and I can also hear it. Its not affecting the machining finish but it is annoying. I can reduce the knocking by physically putting pressure on the lever which engages the feed rollers. I do believe it is the rubber drive belt to be slipping..my question is. Is this common/normal for anyone else?
My overall review of the machine would be = average. which means (good enough to use and get good results, but not good enough to instill any loyalty to the JET brand and keep me buying more in the future.)
-the surface tables are as rough as sandpaper, cleaning the packing grease off with a rag and some kerosine = torn up rag in seconds. the timber slides over it well enough though. I have never seen machine surfaces that rough, it looks like they have used a 6mm endmill cutter that was folding/tearing the metal out of the way instead of slicing through it.
-The jointer fence is so bad, i knew it was bad before I bought it, 2 places to adjust the squareness of the fence = one too many, which creates twist in the fence if your not diligent. there are a couple of allen screws which can be adjusted to set a home position for 90 degrees, they r very difficult to adjust accurately, after about a minute i just moved them right out of the way never to be looked at again. I rarely move my jointer fence from 90degrees anyways, so i wont need a home position guide.
-The jointer tables r not coplanar out of the box (i really had my fingers crossed hoping for this), they r pretty close on mine. perfect on the fence side of the tables, but the infeed table is low by about 0.2mm on the other side. I think i can fix this fairly easily
-Oh yeah...the drive chain ran off its tracks.
-I didnt check the thicknesser side to side variation but it seems it was pretty close, its probably within 0.1mm which will be good enough.
The overall setup of the machine ex-works was pretty good, not good enough to joint a board straight (cutterblock is set too high sniping the trailing end), but good enough that u could unpack it, plug it in, turn it on and thickness a board to pretty close the measurement you chose on the digiset. was within 0.3mm so another minor calibration to be done for me.
Thanks guys.
