I then raised the bit, removed the touch plate and moved the spindle to the new origin. G92 sets the position of the bit end, and z1.5 is the thickness of the touch plate along the z axis. I pressed probe and once they made contact and stopped I typed the command G92 Z1.5 into the command line. I then set the probe along z direction to -10, although that could vary, and made sure the touch plate hadn’t moved away from the soon to be incoming bit. To Probe in bCNC I had to position the bit above the area I wanted to probe, and then set the x, y and z coronadites to 0.

I’ve actually written the code here that I need to write after I’ve done the probe sequence. So I’m going to cut this back and un-solder it. Obviously I haven’t done a good job here. Ok the wire that’s meant to be the shield is making contact with one of the other wires. Extruded aluminium is pretty flat so variation along the piece will be minimal.Īnd the angle will also help keep the aluminium flat, but I need to tapper this so it doesn’t get caught on the incoming spindle. I’m going to use a piece of aluminium angle bar as the touch plate for now. Ok I need to decide what I’m going to use as the touch-plate now. I soldered a crocodile clip to one wire end, and crimped a ring terminal to the other.

I use heat shrink to neaten the joins and check that there are no shorts using the voltmeter. So this doesn’t become a problem later, once the wires are tinned, I snip the ends down a little so I don’t have too much metal exposed. This might be because I’m using thin solder and keep the iron on the wire core for too long. I noticed when I solder this particular type of wire, the sleeving shrinks a little because of the heat. I’m just sticking with the format of shielding and luckily I’ve got a bit of wire that I can use to shield here. Ok I’m going to make the touch probe for the CNC machine using this 3 pin aviation panel mount.
