a CNC machine is not expensive.
Just as, Exercise equipment is not expensive.
What IS EXPENSIVE, is human LABOR TIME spent using the machine.
Having the machine is just the very beginning, now you want to make something, you need to create it in cad, setup the cam, manually check every step of the cam which could be 100s on complex geometries, Then you send it to the machine, it PROBABLY won't work first go, Something probably went wrong with the cam, and you need to go back and edit a bunch of times, the post processor screws up the gcode again, go back, manual edit.
Now, you do this for 1 keyboard, if you only sell 20 of them, how much do you have to charge ? what if you only sold 10.
This is why most cnc places don't even want to deal with small fry keyboard guys, because the setup time on their end, and the back and forth discussion with _the knowledge blank customer_ is tedious, making the job not worthwhile.
And fundamentally, if you look at keyboards, it's a huge waste of resources to machine out of metal, because it's just a decoration that has no function.
For a serious machinist, machine shop, they'd consider it a waste of THEIR LIFE to bother with such a thing.
Yea, you'll find shops that will do it for the right price, but again, I've always been firm on this, it's wasteful and childish.
Going back to the pizza baker example, if the customer is buying pizzas and throwing them in the river, it doesn't matter how much the pizza baker is paid for the pizzas, the customer is Throwing that man's LIFE in a river.
Waste is Waste
TP4 am ashamed to admit, has thrown immense many pizzas in the river.. Tp4 am as guilty as the rest of y'all, Tp4 am AWARE
