Thanks for those tips!
I was also going to ask how accurate it could be if I drive two leadscrews with one belt? If I could use timing belts rather than multiple motors, it seems it would save a lot of complexity for me. The leadscrews will be about 40" apart (Y) and 25" apart (Z). The Y leadscrews would have to move about 50+ lbs I'd guess, and the head will probably weigh a good 50+ lbs also. While mass might be added in some areas to improve rigidity, travel speeds are a very minor concern, so I am not expecting much belt-stretching acceleration. |
