So I have a wall in my garage where I would like to put the frame. I’m trying to find out what is the best size for edge to edge cutting. ---

Bar wrote: > It does now! I fixed it after you pointed that out 😀 yep, looks good (I posted before I realized it was last week’s video). If you want to add a gradient, look at the latest version of my calculator and it shows curves for every degree the angle exceeds the limits. It also has a table on it giving an indication of how much error you get for each band. This is why I’m so interested in the people doing the ‘clipped ears’ configuration, that little extra angle makes a fairly significant difference in the corners. David Lang ---

At some point we need to compare notes, our two calculators show significantly different curves for the adjacent belt limits. you show them sticking much further in to the work area than I do. David Lang ---

Is there a github repo for this tool? I can look in the code and compare it to my math David Lang ---

Based on Bar’s calculator, I’m building a two part frame 3.2M x 4M as that shows green for the whole board. Although I just checked it again and the calcs may have changed as the corners are orange. ---

But also keep in mind that I do most of my cutting on a 10’x7’ frame that absolutely runs into the orange areas. It’s not ideal, but it’s not the end of the world. ---

Bar uses a smaller frame in his office, just check and see if work in the corners is producing errors that you can notice. David Lang ---

One has to wonder - if in the orange area, how large will any deviations from the g-code be? Are we talking sub-millimeter, 2-4 millimeter or more? ---

The short answer is ‘it depends’ 🙂 On my calculator, which is only looking at angles, nothing else [http://lang.hm/maslow/maslow4\_frame.html](http://lang.hm/maslow/maslow4_frame.html) I have lines outside of the green area. Each line is the belt being out of line from the arm by 1 degree more than the prior line. The shorter the belt, the larger the error will be, but if you are supposed to have 1000mm from the spindle to the anchor (belt + arm), here is a table of how much error you will have for each 1 degree of misalignment if the belt + arm is supposed to be 1m long angle effective length 1 999.98 2 999.921 3 999.822 4 999.684 5 999.507 6 999.29 7 999.034 8 998.738 9 998.403 10 998.029 so a small error you probably won’t notice. As I see it, this is most critical during calibration, because you are trying to measure where the anchors are, and if you get that wrong, it will then cascade into all your future work.

I’ve been testing this: [X and Y off by 1%](https://forums.maslowcnc.com/t/x-and-y-off-by-1/23002) Had an issue where the cut was off by about 7mm near the edges on the X axis which really screwed my project up. When testing I was seeing a skew up to 10mm, but after modifying the machine, frame, and tuning I got it down to 2mm. Have some more work to do before I can run another cut and test with a real example, but I’m optimistic.
