Standard MiniMill Prototype Component Costs
Upgrading to Highest Accuracy Trucks and Rails
Add 1800 (mfg 1300) Upgrading to Linear
Position Encoder Add 900 (mfg 630)

Modified MiniMill Prototype Component Costs

Cost Comparison
The motion elements in Modified MiniMill cost
between 1.5 and 2 times as much as those in the
standard MiniMill. This there is also an
increase in the cost of the carriages in the
Modified MiniMill due to more material and
machine required There the Modified MiniMill
Also requires the added cost of clean and dry air
supply. Lifetime costing and machine accuracy
will decide if the added costs of the Modified
MiniMill are justified.
