This is required for Otherplan to understand the size and shape of the board outline.

The Outline layer must contain the board outline, drawn with the Line tool.

For example, to make slots with a 1/32' (0.031') tool, make a row of 0.033' holes, with centers spaced 0.016' apart. If you need them, make a row of overlapping holes that are a few thousandths of an inch larger than the tool and overlapping by about half their diameter.

Larger values will allow you to use larger tools, which will speed up your milling time.

If you’re using polygon fill/a ground plane, set your isolation value to 0.001'–0.002' larger than the largest tool you want to use.

Vias are not plated, so you’ll need to solder a wire on either side of the board to connect vias.

Through-holes are not plated, so avoid routing traces to the top side of inaccessible through-hole pins.

Designing PCBs for the Milling Machineĭesigning a PCB for the milling machine is a little different than designing for a PCB manufacturer. If you’re new to CircuitMaker, check out their in-depth beginne r tutoria l. You can download CircuitMaker on the site. You must also be connected to the internet in order to use CircuitMaker. CircuitMaker is nearly the same as Altium Designer, but it has the caveat that all your designs are stored publicly in the Community Vault. It’s made by Altium, which is known for its professional EDA software package, Altium Designer. This guide shows you how to export your PCB designs from CircuitMaker as Gerber files that can be imported into Bantam Tools Milling Machine Software and milled on your Bantam Tools Milling Machine mill.ĬircuitMaker is a free electronic design automation software package and online project community for hackers, makers, and the like.
