Starting over - Tramming, surfacing, & everything else

I have had some issues since I bought my Elite Foreman. Many of which I think were exacerbated by trying to be a perfectionist with any creations. I’ve been away for almost a year and am coming back with a new outlook. I looked at some of my older cuts and designs and honestly felt proud of them. I want to start fresh and make sure I go in with a better chance of success.

I have the Elite Foreman. I also have the QCW with the legs. Instead of writing a block of text, I will just number my process and questions:

  1. The floor that the CNC sits on is so uneven in one corner that the extendable leg fell out when trying to adjust for coplanarity. I added an inch thick piece of walnut under the leg and it seems to be strong enough. I just the fishing-line test and I was surprised at the accuracy I check both ways twice just to make sure. I think it’s safe to say that the table is coplanar.
  2. I plan to then tram the spindle. I have used Mark Lindsay’s youtube guide in the past and appear to get good results. Instead of using a piece of granite to set the gauge, I’ll be using a piece of float glass. One thing I will be doing differently though, is I will be adjusting forward and backwards tram using the legs of the x-axis. In the past I have trammed both directions using shims behind the spindle mount and that can be a little annoying.
  3. I will then surface the wasteboard. I had originally bought a Amana Tool 45527 4-Flute bit when I was just starting out and I burned that sucker up almost instantly. I then decided to get a Binstak 1” Slab Flattening bit at the recommendation of another CNCer. It works really, really good for flattening my sawmill boards so I will use that to surface the wasteboard.

This is where I plan on starting. If you have any additional ideas, please let me know.

Now for the part I have never figured out - My usual area for cutting is in the front left corner of the CNC (no reason other than preference). When I make cuts, I notice that the further right that the gantry goes, the shallower the cuts will become. It is unfortunately very noticeable. If I remember correctly, once the middle point has been reached, the cuts start to get deeper again. I don’t know how this can happen when the legs are all in the same plane.

My thoughts are that after surfacing and tramming, I can take a large piece of MDF (surface it first) and cut a large circle and see if there is any variance in the cut depth. But as I type this out, I don’t know if that will really work the way I think it will. To make things easier, I will reply with my results after doing them in the next few days.

Maybe I’ll get lucky and everything will be perfect :sweat_smile:

I surfaced my wasteboard. The spindle is in tram in the front left quadrant. As the gantry moves right, the spindle tilts forward and makes groves in the wasteboard. The spindle also tilts forward even more the further back the gantry travels.

I’m at a loss as to what to do. I’ve been spending 2 years on this. If anyone wants to buy this CNC, let me know.
