In left corner of CNC USB controller interface, word ‘Sensor’ should appear for every contact between the tool and the copper plane. In settings set selected input as “Sensor”.Īs a safety precaution, connect the tool and the copper plane with some wire to make a contact. Mk2/4: Designated sensor input is input 5.

Mk2/4 and Mk2 controller have designated tool sensor inputs, while Mk3 controller has software assignable inputs, so you can connect your board at any input. Now connect your copper board to controllers ‘sensor’ input. You can solder wire to it or you could just use mounting screw to attach connection wire to your workpiece.
Since copper board itself is conductive it can already be used as sensor. Mount it properly, so that you avoid any inconveniences later such as vibration, dislocation etc…also make sure that copper board is not in contact with the machine table. Place your workpiece material (in future text ‘copper board’) to machines table. ‘ Warp’ step by step guide for conductive materials (PCB’s):
Cnc usb controller depth how to#
This tutorial will show you how to measure surface height points over workpiece surface whether you are using conductive or non-conductive workpiece material. In case of PCB milling, where workpiece material itself is already conductive, we only need to connect PCB board to controller ‘Sensor’ input and tool itself can be already used as probe. In case of non-conductive material we can use touching probe to measure the surface of material. The most important step of the ‘Warp’ procedure is how we measure the surface. So it is very important that the depth of milling is constant over the whole milling procedure. In many cases conical or D-bit tools are used.
Precision of milling and the distances between pads depend on the milling tools used. Since the PCB milling procedure itself is very delicate and precise (distance between two pads can be only xx mils), already smallest PCB surface height irregularities can create bad results. This feature comes in great help to users that mill their own PCB’s. ‘Warp’ feature is used when applying generated toolpath over bended, curved or uneven surfaces.
