Hi Billy,
many a person has bought a Chinese router only to find they are rather more limited than they imagined. The Chinese are not at fault here,
they certainly don't disabuse a buyer of the realities but they play on the fact that most buyers have no idea how rigid a machine has to be.
Especially when cutting metals. If you think brass is a challenge try stainless steel!
Having said all that, and if you track any of my other posts you'll realise I'm very scathing of Chinese suppliers, they do provide products that people
can afford. You are a prime example...the price was so good that you wanted to try. Even if you throw away all the Chinese electronics as just plain
troublesome then the mechanical parts left over still represent pretty good value for money. If the mechanics are not rigid enuf for your purposes
then you should have bought more rigid design, that is to say its your fault not the Chinese.
Notwithstanding the frustration and effort to get it to work you are there or close to it. Once you get used to generating the required Gcode and understanding
the limitations of the machine you'll be fine.
I have a much better understanding of the basics that I could have imagined since we first got this thing....
That understanding is hard fought but you will use it over and over again.
