The mill has Glentech servos on it so we are going to try and use them.
I know the tool changer is iffy at best. I didn't even know this type of tool changer existed until I saw this one. If it works then great, if not I'll rely on the armstrong tool change method.
I'm not planning on putting an axis on the knee, but want to put a scale on it and hopefully I can get Mach3 to have just a readout for K axis. I posted a question about that but no response yet.
I'm planning on a 4th axis later, but have to get it running first.
I just ordered a MPG for it, next I'll get the scales and reader heads, then the motion controller and breakout boards.
And I'm sure will be more I need to buy.
