hi everyone
the RepRap project sound greet, and you have a very interesting forum, and i was wondering if you gays won't mind if i join in, reason i am asking its because i am not building a RepRap but a CNC machine and i could use your assistance and advice, of course i will try to contribute as much as i can.
by the way my name is Yovav i am an electrical engineer from Israel.
Peace

Hi Yovav,
you're welcome!
Some others (like me) are repstrapping with CNC-machines, so here should be some know-how and advice.
It's a nice 'sidepath' fixing an extruder beside the mill-head and then try additive fabbing parallel to the subtractive as with milling ...

PS: AFAIK most people i met in the forum weren't gay

Hi Yovav,
Nice to see another Israeli here
I'm currently building a RepRap Darwin at the Technion, in Haifa as a project for my B.Sc in mechanical engineering.
Good luck!

Glad to meet you Leav and Viktor
i am also working on my CNC project as part of my B.S at Tel Aviv Uni.
my main difficulty is the size requirement, i need to build a machine with a 2500[mm]x1300[mm] cutting area and an End Product accuracy of 0.01 [mm], so i can't use stepper motor (they might slide) and need to build a closed loop control for DC motors, but my real problem is measurements,
is there a relatively cheap (under 1000$) position system with accuracy of 0.001[mm]?
i am having difficulty finding one of those
nice to join the gang

Hi Yovav,
... i don't think you would find anything with this specs and prices
Look here: - [wwwpdb.heidenhain.de] (last page)
With expensive glass-measures and closed-loop you would receive +/-2 to 3 microns best over 2 meters!
For higher accuracy you have to stabilize the temperature of your machine and the driving mechanics, what's a very big and extreme expensive task.
