i also have to work on the Hall-Effect home/limit switches for my CNC, as well as devise a way to help support the Z-axis.~Travis
I was steered away from optical (on CNCzone), as the router dust may obstruct the sensor, unless i build it into a sealed mechanical sensor that passes a vane through the sensor. seemed like hall would be easier to implement, of the non-mechanical sensors.
I thought my soldering skills were at least passable, until i tried to solder a PL-259 connector on to RG-8X cable. first try: melted the foam core, shorted.second try: works, no shorts.third try: melted the foam core, shorted.i tried my electronics soldering iron first, and got a lot of gobs of cold solder due to the thermal mass of the PL-259. then i tried a small butane torch. no more cold solder, but the heat is a bit too intense. the you-tube videos make it look so easy. and i tried desoldering the connectors for re-use, and only managed to completely melt the insulator.~Travis
my linear Hall sensors should arrive tomorrow
