One basic question
If i choose aluminium as the basic material of the gantry, could i have 6-10mm holes laser cutted at a 20mm aluminium plate. They told me that there is a "law" that says that you cant laser cut holes smaller than the thickness of the material. Is that true ? That means if i have a 10mm thickness steel i will have 10mm laser cutted holes, accordingling about aluminium.
Thanks
