Got to test kapton tape ablation, its easy and you can do it without harming copper, but we should use a crosshatch fill

check this pr https://github.com/tscircuit/lbrnts/pull/10

SeveOP•2w ago

why is it filled tho did you see Shibo and my discussion around filling as the laser would? i.e. with zfill or crosshatch depending on setting?

shibo•2w ago

if you zoom into the filled shape you'd see it's actually a path not a fill

Anas•2w ago

SeveOP•2w ago

how/where is that path configured? But yes that is good ok i think i see it nice work 🚀

Anas•2w ago

Now I think I should work on adjusted soldermask margin

SeveOP•2w ago

yes makes sense! 🍻

Anas•2w ago

we can customize the crossHatch looks

  const soldermaskCutSetting = new CutSetting({
    type: "Scan", // Use Scan mode to fill the pad shapes for Kapton tape cutting
    index: 2,
    name: "Cut Soldermask",
    numPasses: 1,
    speed: 150,
    scanOpt: "individual", // Scan each shape individually
    interval: 0.18, // Distance between cross-hatch lines
    angle: 45, // Angle of the cross-hatch lines
    crossHatch: true,
  })

  const soldermaskCutSetting = new CutSetting({
    type: "Scan", // Use Scan mode to fill the pad shapes for Kapton tape cutting
    index: 2,
    name: "Cut Soldermask",
    numPasses: 1,
    speed: 150,
    scanOpt: "individual", // Scan each shape individually
    interval: 0.18, // Distance between cross-hatch lines
    angle: 45, // Angle of the cross-hatch lines
    crossHatch: true,
  })

Anas•2w ago

do these option costomie how the laser cuts? @Seve Should I add soldermaskMargin option here ?

 const project = convertCircuitJsonToLbrn(circuitJson, {
    includeCopper: false,
    includeSoldermask: true,
  })

 const project = convertCircuitJsonToLbrn(circuitJson, {
    includeCopper: false,
    includeSoldermask: true,
  })

SeveOP•2w ago

yea i think so, note that it can be negative (and usually will be) also note that we should add solder mask margin in addition to the existing solder mask margins around components feel free to join our call today if you'd like btw

Abse•2w ago

we already told him lol

Anas•2w ago

@Seve https://github.com/tscircuit/circuit-json-to-lbrn/pull/31

Anas•2w ago

positive and negative margin

Anas•2w ago

const project = convertCircuitJsonToLbrn(circuitJson, {
    includeSoldermask: true,
    includeCopper: true,
    soldermaskMargin: 0.2,
  })

const project = convertCircuitJsonToLbrn(circuitJson, {
    includeSoldermask: true,
    includeCopper: true,
    soldermaskMargin: 0.2,
  })

  const project = convertCircuitJsonToLbrn(circuitJson, {
    includeSoldermask: true,
    includeCopper: true,
    soldermaskMargin:-0.2,
  })

  const project = convertCircuitJsonToLbrn(circuitJson, {
    includeSoldermask: true,
    includeCopper: true,
    soldermaskMargin:-0.2,
  })

SeveOP•2w ago

nice!

Anas•2w ago

This pr needs merge https://github.com/tscircuit/circuit-json-to-lbrn/pull/33 https://github.com/tscircuit/circuit-json-to-lbrn/pull/35 https://github.com/tscircuit/circuit-json-to-lbrn/pull/37 another one https://github.com/tscircuit/circuit-json-to-lbrn/pull/39 last one 😆

SeveOP•2w ago

since all of this is fresh, you could try a small PR to https://github.com/tscircuit/circuit-json-to-geometry since this is going to be our base for creating flattenjs geometry in the future (optional)

Need to merge, I didn’t have access for that

Anas•2w ago

I tested some boards with laser. I think we need to work on RunFrame to support laser lbrn2

SeveOP•2w ago

like as a preview? When the user goes to export, there's a dialog, we should show the laser preview and allow them to tweak settings there looks good tho RE: SVG-gen

Anas•2w ago

Yeah, dialog to manage the includedSoldermask,soldermaske margin and includeCupper

SeveOP•2w ago

yep!
