Sorry for being such a newbie at home CNC machines but wolffie and leo could you post an example of a product like from amazon or some online store of the wax and dry lubricant? Thank you very much for the tips.
Using hoods instructions I have now switched the CNC to inches (inches, standard, imperial whatever you want to call it). I can move the motor on all axis using my keyboard and it seems fine.
Here is the new temporary homing and limits config.
Here is the new motor tuning config in inches
Now I want to remove this tiny tool holder and replace it with a standard/inches tool holder.
It turns out that it has one of those metric allen head screws on both sides. When I tried to loosen it it just stripped my allen wrench so it is on there pretty tight.
The nut or cap that secures the collet into it says ER11-A. Do I have to take this thing off or can I live with it? I mean is there standard sized collets that I can use in this tiny toolholder? I'm guessing if I switch to a different tool holder I will have a wider variety of collets to choose from and hence be able to use more tools on it. I realize it is just a tiny machine but I'd like more than one collet and I'd like to be able to use tools in inches.
I tried loosening the stresses on the X as suggested by the seller and moved it back and forth some and retightened it but that did not help the crunching/rattliing sound when it moves in the -X direction. Neither did slightly loosening the step motor and then retightening it. Maybe it's the nut on the gantry behind the Z that the X ballscrew slides in. Maybe if I loosen that a small amount and move X back and forth and retighten it maybe that would fix it?
