Need some help with my machine ,3xxl, and maybe the foundation it’s on. Had a accent line in a piece with a 60 degree vee bit to be just about an inch inside of the profile cutout. The line towards the back was noticeably deeper and wider and the contour cutout was much deeper in the back too. Very noticeable in the wasteboard that I have. Posted this and a resurface of the wasteboard was a common suggestion. So I went in to the shop to start with that.
Before I started to resurface I checked a few things. The eccentric wheels on the y1 and y2 specifically the front ones were loose. Like free spin. So I tightened them up clockwise. Then I checked my tabletop level. Side to side level. Front to back the front of the table is low. Consistent low and same from left to right side. Figured that was ok because the re surfacing of the wasteboard should address that. The table top is 3/4 mdf and actually has a low spot/dip that was visible under the level. Placed a straight edge on the shapeoko base mdf with the waste board removed and the back corner has a low spot. Like ~1/8". The machine is on the pink 1" foam.
Hopefully that paints a picture that makes sense. How far into this do I go to correct. I made the table alone so it’s believable that it may not be 100% level and I like beer. Do I redo the top and then check as I go or just do another wasteboard and see? Looking for advice. The picture of a paper shows the wasteboard thickness at multiple spots.
