I got a working pcb built. And learned a crazy a,out getting it going.
- Make sure the area is flat… Extremely flat.
- Is your pcb flat?
- It your are building close to the edge of your board make sure it’s exactly square.
- You probably want to print the mirrored bottom image it you want to mount your parts on the other side. Check this before you print.
- There are tons of header pins in fritzing. Check that the pin distance matches what you used.
- In fritzing set the auto router to use extra large traces.
- Use Inkscape to turn lines to paths, don’t forget to union the,.
- If you are using an engraving bit, don’t move it when it’s really close to the board, you may break a tip.
- Slow movement gives higher quality pcb. I used x and y of 2mm/s and z of 1mm/s.
- Engraving depth of .03mm is just about right. .1mm is too much and .02mm is not enough on my board.
- Make your pads as big as you can.
- Use jumper wires to fix your board errors.
Things to still figure out: engrave the outside of the line. How do you do that? Tried the obvious option in estlcam but it looked the same.
And here’s the finished product.
