  • Surfacing Spoilboard


    Okay, I just know when I get the answer it's going to be something small and stupid but ...

    Using Mick Martin's Spoilboard Wizard, if I center my bit on the lower left corner of the spoilboard, set X0Y0, then lower Z to touch top and run the TAP file, I get something like Exceeded Soft Limits error [Y+].

    Now, if I run the spoilboard wizard and use machine 0's but add an extra inch to Y dimension of spoilboard, it cuts fine. It does run off the front of the spoilboard and cut air though (about an inch or so, to Y0 machine limit).

    I am doing G49 to clear Z limit and G92 to clear X and Y limits before zeroing X0 and Y0 to the corner of the spoilboard.

    I know it's something simple, but I am just missing it.

    If your bit is on the spoilboard, type g49 and then type g92z to set z0. Then run the tap file.

      I have run G92, does that not clear all axes? My error is in the Y axis?

        Sounds like where the spoilboard corner is isn't the true X0Y0 which isn't uncommon. That is why I use the machine zero when running the spoilboard wizard on mine. I've never had much luck using a local zero when using Mick's program. If I need to use a local zero for some sort of surfacing operation (flattening slabs, etc) I just make a box in Vectric the size I need and pocket it with the appropriate size bit.

          Sounds like it is working as intended. Flattening the table tp successfully when the factory x and y location is used. When you have used a local zero it results in a y value that would go beyond the machine limits.

            Thanks Logan!

            I got my spoilboard surfaced, which is the ultimate goal. I was able to use machine zero and tell it my spoilboard was longer in the Y dimension than it really was to get it to mill the rearmost inch off.

            I was just trying to figure out why things weren't working from local zero? I even dissected the G-Code in the TAP file, and it even made sense!

              Yeah, but the machine would cut all the way to the back when I used machine zero, so it has to be able to reach back there, right?

                G92 by itself restores machine coordinates. If you wanted to set local x, y, and z to zero, you’d have to do g92 xyz.

                  I have an additional question about the spoilboard wizard. When it asks for the diameter of the router bit, should I enter the total width of the bit or the cutting width? On the Amana RC-2263, the total width of the tool is 2.75 inches but the cutting width is 2.25 inches. Many thanks for any help.
                  cheers

                    It’s always the cutting width.
