Re: Struggling with coordinate system on bCNC

The standard for CNC machines is for machine zero to be in the upper right and all work to be in negative space.

That said, you can move the spindle to anywhere you want and set your zero there.

Re: Shapeoko 3 Z-carriage mod and electronics enclosure upda

That looks great. I love the industrial control components. Can you explain what they are all for?

That Z axis mod looks like a great idea - I might have to implement it myself.

Re: Change minimum search term length to two characters?

The board is setup to use the mysql search settings. The search length is set by a mysql setting and I'm not sure that I want to change it.

Setting the length down from 4 to 2 will probably cause some DB inflation and probably slow down searching.
