Hi there!
My drive wheels are at the bottom of the machine for two reasons:
The drive wheels are very large in order to make the resolution as high as possible. Twist in the shafts are limited because the 22mm pipe has a large diameter, countering twist, and the inner shaft is doubled up - 8mm threaded rod and a 15mm copper pipe combined.
Morgan is almost ready for public release... and is is busy making it's first child ;-)
Cheers,
Quentin
My drive wheels are at the bottom of the machine for two reasons:
- They would intrude into the build area if directly below
- If above the arms, the weight of the machine would be very high, and then you also have to devise some system to suspend and hold the motors, without interfering with the bowden cable...
