There you go you see you are already upgrading and haven't even built it.! . . . Plus you would be upgrading it with components that are not ideal.
This is why we tell people to do the research and check out build threads so they can see the differences and why we fit and recommend the things we do.!

All these open builds appear to be built on the same or similar profiles.................
Well often it's because they don't know any better, often it's the first machine they have experienced and indeed it does cut, but that doesn't mean it's cutting correctly or efficiently.
Only when they get a better-built machine do they realise just how poorly it was cutting and what can be achieved with a stronger machine. I see this all the time with customers who have started with work-bees or open build type machines, their jaws drop when they see a 12mm cutter cut through 18mm MDF in one pass. Only after they have had one for a few weeks do they realise just how compromising and limiting the machine was to them.

We see this happen on the forum when people have built machines from plans and the CNC Bug truly bites them, they upgrade and waste money only to eventually realise "you can put lipstick on a pig but it's still pork at the end of the day" only when they start to listen and do the research and build a better machine do they understand how bad the old one was.!

Also, very few want to admit they have bought a lemon because they want to sell them on. Ask anyone who has bought one and moved onto a properly built machine and you will get the true answer.

Now I realise when I say these things people will think I'm just saying these things to sell machines or steer people in my direction and indeed it does at times stop me posting some things I could, but this honestly isn't the case.

I say what I say so people go into buying these things with their eyes wide open and fully aware of what they are buying because the last thing I want is new CNC users being turned off CNC because they have bought inferior machines thinking they are capable of much more than they truly are only to be frustrated and give up.
Again I see this happen all too often and ALL my advice is based on real-world experience with helping people and not just customers, people on various forums who have sought me out.

However, at the end of the day, it's down to the individual to whether they believe or trust what I'm saying. Sooner or later they find out one way or the other.
