Sorry for the delay, this has been a busy winter season so far. At the moment, my problems have been solved. Here is what I've found.
It turns out that there are 3 versions of the manual for the CL86T, V3 being the most current. The V1 manual was included with my drivers. In the V1 manual, there is no specific callout for resistors. The diagram does show a small square in the wire path, but no labeling or further documentation regarding resistors is included. In addition, the V1 manual states "5v or 24v , 5v recommended" but they do not include any more precautions or resistor callouts (see attached pic). The V3 manual which I acquired online goes into much more detail about 2k resistors being required when the drive is used at 24v (see attached pic).
With this in mind I went to Stepperonline customer service and emailed back and fourth with Wing. Wing provided excellent service. He helped me to troubleshoot the problem and offered to replace both of my drives that were damaged due to 24v use without a resistor for free. The only downfall is that even though I purchased through Stepperonline's USA warehouse, I had to return the faulty drives to China. This was $58 through USPS.
During the conversation, I drew a diagram that could not be more clear and asked Wing to confirm that it was correct before I wired the new drives. He confirmed the attached diagram (see attached pic with yellow highlights).
Since then I have received the replacement drivers and wired them with 2k resistors to the screw down 24v headers on the Centroid Acorn board. It's been 2 months now and so far so good!
Thanks for the help troubleshooting, I hope this helps someone in the future. In case I wasn't clear, DO NOT WIRE THE CL86T DRIVERS AT 24V WITHOUT RESISTORS!!!!!! I LEARNED THE HARD WAY haha good luck!
