Day 37

Morning
I started to look at the cost of all the parts needed for a welder upgrade. I tried to figure out exactly which power supply I needed for the plc, then gathered up some part numbers and prices to make an excel spreadsheet. I've got all the parts that I think will be involved, but it's still fairly rough.

Afternoon
There was an issue getting the plc on EBW4 to communicate with a remote module. Tony went out to take a look at it, but that didn't do much good because he needed a newer version of the Allen Bradley software to communicate with it. Tim showed up and started diagnosing the problem which stemmed from the device not having an IP address but requiring access through IP to configure that information. Despite those problems, the end-bell was refastened and the pumps were started. The welder got down to about 2 Torr without any jets.
