I hope the AM882 is a straight swap for the AM882h as I used the broken one as pattern for setting up whilst I'm waiting for the new one.

Omg what have I missed now!!
I thought you could supply it with 5v on the connections you connected to the drivers... have you tried that? :D

You need 5v + 12-24v for this bob the 5v can be supplied by the usb or by the bottom right hand terminals marked 5v PC

I have them connected to the dir/pulse +'s for the AM882's is this correct? 5v coming in from usb.

All I need to do is supply the AM882's 5v+ to both these pins? It wouldn't matter where it came from.

Carry on,you are close now!

Hahaha :D

Just try your first one before building a new.
Find the "weak" spots and plan a solution or upgrade..
Might be that you are satisfied with the one you got? ;)

That's the plan, but I have a project that needs the extra Z travel I should have 12cm now but to get any more I need to rebuild it as the gantry height is the limiting factor. I'm going to use my machine for this project if I find the Z travel to be a limiting factor then I will have to sort it. I have a few ideas how to carve it up so I can get away with 10cm travel but until I start carving I won't really know what I need lol.

The next month or 2 is learning how to cut with it and then tests cuts, I have no illusions the more complicated stuff I want to do is going to take me months to work out how to make lol. The woods are very expensive to work on so lots of test cuts and scale models first ;)

What I have no idea is what bits to use to mill the woods, was planning to use 2 flute router cutters for the roughing and ballnose end mills to smooth off.

What I really need is a 5th axis and 40cm of Z but that's not happening but I can dream ;)

Wow :D

My mind is more limited.
I can't for the life of me come up with a project that requires a 5th axis :)

Well.. if I were to start building engines and stuff maybe..

What sort of things do you want to make with your router?
