I asked this in my build thread, but then I though it would get better attention here. I have a Hypertherm PM45 with a machine torch.
My cnc cable chain guide rolls at about a 5 to 5 1/2 inch diameter. Here is a pic that shows what it looks like:
I'm worried that this tight radius will shorten the life of my plasma torch cable. I called Hypertherm and they recommend an 8 inch minimum diameter.
Should I worry about this? The fellow at Hypertherm said that if it ran in a manufacturing plant that off course it would wear out faster but in my low-use application I could be OK?
