Then export that drawing and edit it with equations instead of dimensions is a bummer.
Everyone’s frame of reference is also different. Some want to start from a table they already have, some want to start from a minimum work area. So that changes the equations.
I am not exactly sure what equations would be needed here. The calc gives you what you need. the temp struts and strut plates make holes to follow. The only thing is Y clips and the spacing there is simple to divide evenly, and not critical to be perfect.
What dims are needed to help that are not included in the calc?
The only thing I remember being concerned about, that I used that picture for when building mine, was to know how wide the runners down the side needed to be to make sure it fit.
Because I was making a separate spoilboard in the middle, I only had MDF strips down the side.
Maybe this illustrates it. 2 out of 4 of these will vary depending on router and homing position. That 60mm dim, changes with XZ plate thickness as well.
In general, just looking for simple reference to figure out how much longer than y cut area and what size runners on each side of x cut area need to be. This allows me to build the table while the gantry is under construction. -Steve
So that pictures helps you? 110mm give or take a few mm, and depends on your preferred endmill diameter and homing position.
Again. I screwed up the yellow brick road here not just showing people a single flat sheet table. There is no need for fancy strips on either side. My builds need to be bone stock period. Pretty much minimum viable product or everyone assumes they should be doing what I do.
Good idea. When you fly me out to do the in-person build so you can learn what needs to be improved like someone suggested, you can pack up that table and send it home with me too
I do actually have a friend coming to do a full build start to finish using the instructions (as soon as they are done enough) and I will quickly see where major deficiencies are.
Okay now the million dollar question. Would it not be easier to not think about any of that and just build a big flat rectangular table? Asking for a friend so he can fix the instructions.
I think that it would be good to have one minimum. “This works.” Put some simple ideas in the docs from “a sheet of OSB” to “something that you can do with a circular saw.”
I also think that something which highlights is good. It means we can show the really nice looking fancy stuff without intimidating the new guy who isn’t sure he can build a fancy table.
Maybe have a forum section for tables? Sub forums for ZenXY, MPCNC and LowRider? Or maybe “Cheap & Easy” to “CNC Cut”
But you tell the calculator the cut area you want, and it tells you the flat rectangle area you need, right?
So you take that area and add an inch or so just in case, and that kinda guarantees you are not too big, not too small, and have some error margin if you really want, right?
Yes, but on the x axis, it does not break down the width for each side (assuming they are not equal). This is in case you want to add a material on each side of your cut area. Perhaps to avoid a seam in cut area or to use a different material than cut area.
As I think of it, it would be relevant on y axis as well if the added length is not the same on each end.
