received shipment of one of these: www.ebay.com/itm/235593572193
it is a Modbus K-type thermo-couple device, with read-type 04, address 1, for temp C in format "270" for value "27.0C".
my plan is to attach the thermo-couple to the spindle to monitor its temperature.
i also plan on getting some spools of waxed string so i can do some old-fashioned wire-lacing on the machine to bundle wires and air-lines. it just looks neat, and i rarely change the on-machine wires now.
