Task Description

Swap out the absolute encoders on A2/A3/A5/A6 from the broad come encoders to the new magnetic encoders https://p3america.com/erck-05spi-360/

Design new mounting systems for the encoders on the respective axis.

Reason for this task is due to the broadcom encoders not following the same SPI bus protocol which makes it difficult to handle the outputs.

Task Breakdown

Look at the datasheet of the encoder to evaluate how it works and should be used
Come up with proposal of replacing the current encoders with the new ones on the respective axis. Start with axis 5/6 and do PDR before doing A2/A3
Redesign the mounting for each axis
Consider possible weight reductions that could be done on each mount

    • Magnets for the encoders can be attached to the 3D printed shaft attached to the pulley, the length of this shaft will be determined after testing the encoder’s operation.

    • The shaft’s length and diameter has been modified to fit the magnet and so that it does not interfere with the encoder. File is under Sandbox > Shahzeb Ali > MR25-A56-P013 (Shahzeb).
