Hey everyone, I just got a brand new 15” Grizzly planer. I put a digital gauge on it and ran a few 2×4s though it to test the planer and gauge. I noticed just as the board would exit the planer, the gauge would jump up to a smaller dimension. EX: if I have it set on on 1.000” it would jump to .950”. I could not understand how it would go “up”? o-yea I did have the bed locked. I examined the planer and noticed that two of the lead screws wiggle. The left one on the input and the right one on the output. This is allowing the bed to teeter corner to corner about .050”. I called Grizzly and the technician did not have a slam dunk solution. We decided to install two new lead screw nuts as it appear the nuts have too much slop. Has anyone else had this problem. Any information or suggestions would be helpful. Two short videos of the lead screw wiggle below.

How are you wiggling the screws? I just got my grizzly 15” about six weeks ago. I just went out and pushed the front two screws a bit, and there was no play.

Marcus, I am just pushing on the output bed with about 5lb of pressure. With the locking screws off, the bed goes down about .050 and the screws wiggle like in the video. With this locks engaged the bed is fairly tight BUT when the wood exits, it puts so much down pressure on the output bed it slips. The output end of the bed goes down, and the input end goes up. Since the locks are on, the bed stays in this position…that is why the digital gauge would measure less when the board would exit. The lead nuts do seem real loose, although the screws could also be incorrectly machined? Can only eliminate one thing at a time. I’m about 2 hours from their store in PA, I might throw it in my truck and take it to them to look at. Getting antsy to make some chips. Don’t like waiting.

I pushed on my bed every which way I could, no movement of the bed or screws. Hopefully Grizzly will get it figured out for you.
