NOTE:

Currently the primary differences between the aluminum version and the

printed version are as follows:

•The aluminum version uses precision series motors for J1, J2 and J3:

•J1 = SKU: 17HS15-1684S-HG5

•J2 = SKU: 23HS22-2804S-HG50

•J3 = SKU: 17HS15-1684S-HG50

(the printed version uses economy series motors as shown in the bill of

materials)

•The aluminum version uses different motor mounts for J1 & J3.

•The aluminum version uses a different spindle and tension plate for J2.

•The spindle and plate for the aluminum (precision motors) have a

14mm bore.

•The spindle and plate for the printed (economy motors) have a 12mm

bore.

•The aluminum version uses a slightly different motor support for J2.

•The bore for the aluminum version is 1mm larger, has a split in the

ring for clamping onto the motor body and it does not have the

extension and hole for the spring dampener.

•The aluminum version does not use the spring dampener components.

•The aluminum version uses DM542T and DM320T digital stepper drivers.

•The printed version uses analog ST6600 drivers.

•The aluminum version uses only the chain drive for J3.

•The aluminum version uses the wiring harness as outlined in the wiring

harness manual on the project page.

The aluminum and printed version can be constructed either way – (using

precision or economy motors). Both sets of models (.step files for the

aluminum version and the .stl files for the printed version) are included in both

sets of models to accommodate the differences listed above. The files for use

with the precision series motors have the suffix “- precision GB”. In the next

few months I will be creating a new manual showing the robots construction

using aluminum components and the precision gearboxes. At that time I will

archive the current manual replacing it with the new manual and obsolete the

current instructions using the economy components. The design going forward

will be using only the precision series motors and the digital drivers as these are

far superior for a relatively minor increase in cost. The current manual can be

used for constructing the aluminum version given the changes outlined above.
