Dewalt Shifting Questions

[Ben Piecuch]

A question for the teams who have successfully shifted the Dewalt XRP's.

Does it make a difference how you control your servos to shift? We are presently running both servos off a single PWM Y-cable, so that we only need to use one variable in the code. The alternative is to run two different PWM cables and use a second variable in the code. This isn't a difficult thing to implement, it's just a pain to switch it over at the moment.

Our concern is this... Since the servos are powered through the PWM cable, and we're presently splitting that with a Y, are the servos only receiving 1/2 of the power they require?

Thanks for all the help.

We are using the Y-cables to shift both servos at the same time. Actually, we are using two Y-cables to shift 4 servos at the same time (two sets of CIMs and DeWalts on each side.) It works fine.

if you are having trouble shifting the dewalts using the set-up described in the whitepaper, it may be because of the indexing clip; there is a small metal clip that serves as a spring that helps keep the dewalt in gear; unfortunately, it also makes it hard to shift using the servo. if this is removed, the servos shouldn't have any problem.

Problem solved. It was a combination of a low backup battery (which powers the servos) and one of the dewalts with a sticky shifter. We replaced one entire side and it works just fine.

Thanks for the help with the Y-cable. And yes, we have already removed all the detent clips.
