I have a large number of cad 2-D plans, and eventually got an eShapeoko to cut them out accurately. But it uses an Arduino running GRBL, and this turns out not to have tool radius compensation.
It would be a huge job for me to redraw all my plans - created over many years - all slightly wider. But if I don't, all cutting will be slightly too small by the tool radius.
One way of minimising this problem would be to use a very small tool - sub-millimetre - but that would be very delicate, and I can't find many around.
Does anyone have any other suggestions? Or should I go for using something like LinuxCNC and redo all my electronics?
