Encoders for Drive Train

[GRSICP]

Hi Everyone!

We are hoping to put encoders on our drive train this year. We expect to again use the Toughbox Mini Gear Boxes on our drive train (http://www.andymark.com/product-p/am-0654.htm). We are having trouble determining which encoders to buy. We have limited tools and machining ability so we want to purchase something we know we can install successfully but will provide accurate and precise readings.

We had hoped to use a CTR encoder, but those seem to be out of our league in terms of installation. We liked the E4T OEM Miniature Optical Encoders from AndyMark (http://www.andymark.com/E4T-OEM-Mini...-p/am-3132.htm) but even after reading the installation instructions, we still weren't quite sure if installing this encoder would require machining capabilities. We also thought about purchasing some CIMCoders (http://www.andymark.com/encoder-p/am-3314.htm) but weren't sure if those would work with the Toughbox.

Which encoder do you recommend we purchase?

Thanks for the help!
