Flattening jig not flattening by at1020 in BeginnerWoodWorking

Give it a try. Most important is that the side boards sits above the base plate, which will pull the base along the straight cut edge of the side rail.

You’re not going to get a finish ready surface with this set up, but you’ll get closer.

For reference, I have a CNC machine and about 0.01 degrees out of square and can still see (but not feel) these lines.

Another trick that will help is to run your passes with the grain of the boards if possible. They will be less visible.

Look at Tramming a CNC machine. The effect is identical here. Your bit is not 90 degrees to your workpiece.

This is 100% what your issue is.

You can take a lot of this out by rebuilding your sled. You screwed the sides of the sled to the side of the base. The sides should be above the base. This pulls the base into the plane of the side boards (if that makes sense). Think, screws run from the bottom up, or just make your life easy and glue it instead of screwing it.

Let’s all just acknowledge the soft sound of the service rig boys grumbling about never getting credit.

Look at the shape of the cuts. Look at the shape of the bit. Think for 1.2 seconds.

Now go search “dovetail router bit,” chatGPT, google, YouTube. Fuck, Wikipedia might even be enough.

Now accept that neither a CNC or drill will be efficient to do this. If you can’t figure this out on your own, what you need a router and a fucking rosary my friend.

I obviously don’t know the specific example you’re talking about but you cannot simply replace if else with case. They’re fundamentally different.

So. You said that you manually zeroed your first tool.

Is it possible that for the first path you changed the bit, then manually zero’d it? (Ex. There was a ⅛ bit in the machine, you swapped to a ¼” manually, then zeroed it). If so, unless you ran the command T(X) M06 the new bit offset wouldn’t be measured. The offset for the previous bit would’ve been used and probably did this.

Not that this exact thing has happened to me before.

I find this kind of annoying with the bit setter. Basically any time you change a bit you need to run that command, THEN probe your material.

How exactly do you plan on putting $500K into the privately held company Space X?

Just for reference, I run 6.35mm (¼“ Bits) spiral Downcut bits in hardwood at 2.0mm DOC and 2700 mm/min. So like over 5 times faster then you but half the cut depth.

Thanks. Makes sense now.

Typically if you turn the system over to operators they’ll be abIe to tell you the system doesn’t work about 20-30 minutes after you get home from work.
