 What can be done with this? | |
Some tim ago i saw a nice design: 
What do you think - it's worth time and money to build this?
- working dimensions: ~ 30cm/50cm/7(10)cm
- acme threads 4mm pitch; nut-spring-nut anti-backlash
- microstep driver (A3977/A3979)
- 20mm/16mm/12mm rails
**************************************
What I want to do with the machine:
- mill-drill-cut PCB's,
- acrilic engrave and cut,
- small aluminium parts
**************************************
For the moment I use this http://www.cnczone.com/forums/showthread.php?t=42554, but i'm unhappy with:
- speed
- bending of the threads
- noise |
Linear Mode
