It looks as though my machining deal may fall through, and this thing is taking forever! Since I have no machine shop at home, I'm thinking of building this in 16 or 20mm MDF just to get it going, then change bits to ally as I go. It may not be the stiffest or most elegant way of doing it, but I've spent enough on this so far and it'd be great to get it going and iron out all the bugs (which I'm sure there will be plenty!). I'll also order the Probotix steppers next week which should hopefully complete my electronics (may need to solder up some simple current limiters...).
Might do some FEA this weekend and see what the MDF will do for me. |
