As some of you know, I have a side hobby/business of building electric guitars. It's fun, and I enjoy it, but I am such a perfectionist if the gaps aren't just perfect I toss the whole thing.
So I wanted to get a CNC machine to help me out with this. Granted, I know NOTHING about CNC's. But a small investment should turn into a reasonable return.
So I bought one used from a guy, I told him I would like to have it to where I buy it, can get it set up, and have it run a few programs he provides so I can get the hang of it a little. He tells me no problem.
He ships it, I get it, he packed it very well, I load it and take off. He tells me to call him when I get it all setup to get me through a few things, he e-mails me some files, etc.....so far so good.
It takes me 2 months to get it all set up, yes, that is a long time, was it also a crazy 2 months? Yes. In the meantime the shipping company sticks him with another 300$ for some crap, that was not his fault, and frankly did not happen. I said I would help in whatever way I could, and even sign affit davits.
When I finally get it set up, I run a program that I bought from someone else, well, the machine and the computer are not sycned as to where the table is, or indexed. The machine keeps trying to go outside it's physical area, and makes a ton of noise. I tell him about this, and he tells me you need to zero the axis and here are a ton of tutorials. I finally get him to tell me how to zero it out, but it still isn't indexed, which is the true probelm.
His answers are very short, and it appears he has a disinterest in helping me get this set up. I am thinking he is frustrated about the shipping charges and taking it out on me. Since I can't get any help, I decide to say f it and sell it. I have thousands into this thing, and I can't get the proper help to get it set up and to run the files to get familiar with it, as I was told would happen.
I just tell him, you know what, I don't have time for this I'll just get rid of it, because I just didn't want bad blood. My brother weeks later reads the exchange and says it's clear he isnt holding up his end, yadda yadda you should tell him something.
So I did, basically it turned into I gave up, I didn't ask for help (when I clearly did and got some very short, and non-helpful answers) and I am taking it out on him because I don't know how to run the machine. That I just want someone to hold my hand and tell me everything to do (while in the same breath accusing me of getting it all set up and running programs that he didn't write) Pretty much, I'm the one at fault in his eyes.
I'm really not one to give up on things at all, I would have never gotten to building guitars, much less a college degree, or working on cars if I just gave up, but I considered it a lost cause and cut my losses.
So what do you think? Am I at fault for not pressing him for more help? Or did I truly not get what I paid for, a machine that was supposed to be set up to run his programs (some of which he never gave me). My thinking was you said you would help me do this, but never expected me to have to index it to properly be able to run your files as well?
