Great idea on the thermal compound, I have seen others use it on the Gecko's.
So the back plate was painted, there is an explanation for most things, so yes remove it and provide a more direct pathway for the heat.

With respect to the temp sensors, I am a big fan of monitoring esp when you are uncertain of outcomes. That's the thing once you have measured you "know" then you can dismiss the issue as not important or needing further attention.

And - your build is going very well, enjoy the process.

Rain Rain Rain and more Rain. I spent most of the weekend messing around with cad/cam software (trying to learn).
I did however manage to shove everything in my garage to one corner to make some room and get the MM out of the rain. I have some welding and a lot of drilling to do yet but it's getting there.

Looking good! Keep em coming!

Good progress Jay!

I have comparable drivers, and they rarely get very warm.

Be careful of your back when you move that beast to its permanent home. :eek:

Jeff, if you don't mind me asking, how much were these drivers a piece?

I ran into a good deal on a air cooled spindle here locally so I am going to sell off the 2.2kw with the vfd that I got on ebay. If anyone is going to be buying one of these PM me and well work out a deal on this one.

Wow your practically a neighbor considering how far away some other memebers are:) I live in Belvidere NJ. About 2 hours from you.

Good job on the build so far:)

Thanks you the comments guys.
My back is killing me the past week, so I'm taking it easy and just put-sing with small stuff this weekend. I need to take my table apart and flip it over so I can template the rails but it's going to have to wait until I feel a bit stronger. :(
