I was told by a Fadal Service guy that I could add RV Antifreeze instead of DowFrost. He said "Make sure it's RV Antifreeze and not regular auto antifreeze". I read the bottle and it said that it wasn't for Gas or Diesel engines. Whether that makes a difference or not, I don't know. When I first filled it and plugged it in, there were leaks all over. The X, Y & Z axis all leaked. So I unplugged the lines going to the bearing blocks and joined them together with brass compression fittings. Fixed the leak. But I'll bet I lost about a gallon into the coolant tank. So maybe it's the coolant and the RV antifreeze vaporizing while I'm milling? |
