Hello all,

I have had a read through all the threads and seam to have a problem others have experienced. When I have set my board up as per the instruction, all went well as I bought the 3 axiz system ready kit.

I have then turn on my PC and was trying to setup router on Mach3 which has cause me a few issues. Must watch the videos. I have no limit switches or e stop connected as my router is 15*15 inches.

While trying to jog my machine the cooling fan dropped in rpm. A short time after it dropped in rpm again and I got a strange smell out of my xylotex drive box. This smell I thought could be become it is all new gear and let it cool for a while with out power. I have turned it on and had the fan drop in rpm again and heard some cracking noises and strange smell.

On closer inspection all the wiring is correct but the connector that plugs into the steppers had a pin not connected properly.

Could this result in a fried board?

any advise would be helpful.
