Temporary MDF machine. My final goal is steel and aluminium, but I was impatient, so I build MDF one. Here's the test drive:
I'm currently setting paralelles and 90deg angles bit by bit 'till I get something I can make aluminium parts for new machine
max speed x:9.5m/min, y:8.5m/min, z:12m/min
steppers are 382oz/in, ballscrews are c5 (x,z) and c7(y) 20mm lead.
Check your motors if ordering from kelling inc. I didn't, so one year later, when I dismantled old machine, I had an unpleasent surprise. Instead of 425 oz/in i got 382 oz/in motors a year ago. Figured it out when shaft diameter didn't match the specifications. Wrote to kelling, not a word from them. Doesn't matter, another oportunity to learn.
Check the stuff you buy from ebay. I ordered 8 same hiwin blocks and inspected only one, 6 months later, it turned that I got 4 blocks of one kind, 3 of other, and 1 of third kind. However, they were all the same height, so it's fine (though, one is much noiser that the other seven
)
Also one more warning, beware of ebay rails/blocks that are not NIB, I got some that were clear when I got them, and few months later they were becoming rusty - NIB ones didn't.
One big Thank You goes to tahustvedt!
