if you are just joking with me 3v0 you need to give me some sign, because you really hurt my feelings with some of your posts (not really), but i do feel like I'm being overly criticized. could you at least put some smiles in to make your replies more friendly?
No ones being mean.
We simply see too many people with little or no practical knowledge wanting to build overly complicated, inefficient, unnecessarily complicated, time consuming and expensive stuff they dont fully understand that many times already has a far better factory made solution available out there for far less.
CNC anything is one of them.
Are the smiley faces doing it for you now?
TCM... that's a nice looking home-grown CNC system. What does he use it for? I see a R/C car in some of the pics, is he making his own parts?
Well right now he is using it to make replacement parts for itself. Its sort of building its own replacement of sorts. It had some severe stability issues!
He went too cheap on everything and used undersized aluminum and motors which gave it too much flex and not enough power to work accurately.
He is rather typical of some of the posters we get here as well. I told him he needed much heavier and stronger material for the frame work.
But he just knew that this aluminum was going to be plenty rigid and more than strong enough but.... Not even close! It had .0005' step rates and about .350" of flex!
This made it very slow moving and rather unstable when it was cutting. Hence the rebuild.
He does wood working and is into model planes big time! Eventually when he has the rest of the accuracy and stability issues resolved its going to be set up as a three axis wood router and light aluminum mill, and adaptable to being a four axis hot wire cutter for doing foam wings and such parts.
Since the pictures where taken the Z axis has been redesigned and it can do basic aluminum milling now. It still flexes a bit but not nearly as bad. Plus the travel speeds can go up to 90 IPM which is about 10 times faster than before!
We are pondering on converting my lathe and mill over to full CNC drive this winter now being they are built for actual metal work!
Once he gets the system debugged I am building a 6 foot by 12 foot CNC plasma torch table system. I may build it as a multi purpose machine and make it capable of wood router work and water jet cutting too. The cost of the water jet system may prove to be too expensive at this time though.
