is it normal?

for example
#0 P1900 S2000

It should move from actual position (center) to that 1900 point. I’ve been using that kind of commands several times, and the servo can’t do the expected.

  • It sometimes moves to the end.
  • other times a few steps.
  • other time it only moves a simple step and i can repeat the same command but it always move one step on every command sending.

In a few words, the servo gives aleatory responses, not the expected.

The support team from the website where i bought it, told me before ordering the product that the SCC-32 is great for that linear actuator, it should work fine :frowning:

I’ve two linear actuator, i’ll try with the second now, to discard that possibility.

You may want to put a multimeter across the power to the actuator to see what the voltage drop is when the actuator tries to move. You might also try large moves without the speed control and see what happens.

Yes, not sure why you are even using the speed command on an actuator that takes a full second to move 1/4". No need to slow this down. :wink:

wow, Against all odds, the problem seems to be the baud rate jumpers.
I pushed then a bit and the servo works perfect now, maybe they had some noise because oxidation or whatever…

At least by now, it works very good, i hope not to have the same problem again tomorrow.

Thanks all :wink:
