Unable to update Firmware from 4.1.33 to 4.1.34 [SOLVED]
Hello everybody. I have a RoboClaw 2x7A. Freshly installed MotionStudio. This tells me that i have to update from 4.1.33 to 4.1.34, so the RoboClaw is properly detected. It then tells me to power the RC off, press mode (and hold it, i presume) and power on. Then the LEDs start cycling in the indicat...

Re: Position Control jitters around target position
Oh, about the hunting: The target position is reached exactly, then it is stable for maybe 200-300 ms, then it jumps 100-200 steps away and crawls back to the target. Then the cycle starts anew, only in the other direction. It does not stay long enough in the deadzone to stop the movement. At least ...

Re: Position Control jitters around target position
Thank You. Yes, we definitively have some backslash, we know this also from our older motors and controllers. Everywhere we allow some amount of being not-exactly-on-target-position, so no problem here. I was under the impression that the RoboClaw stops the movement as soon as it is for some amount ...

Re: Solo: Confused about SetPinFunctions and S2 ... S5 Modes and Firmware 4.1.33
Great. Still, i would like to know if i'm correct about the switches: Physical S3 is S4 in the API? S5 in the API is not used for the Solo? S3 in the API is what? Can't be S2-Physical because that is the Serial, yes? Can't be S4-API because that is S3-Physical, yes? Why do i have to set S3-API if it...

Solo: Confused about SetPinFunctions and S2 ... S5 Modes and Firmware 4.1.33
Hello everybody, we just went from 4.1.29 to 4.1.33. The "Limit Switches" or E-Stop are no longer working as before. Reading the Datasheet and User Guide leaves me in utter confusion :D. The Device is a RoboClaw Solo 30A, packet serial, communication is over USB only. I have a linear movem...

Re: Position Control jitters around target position
The "next week" thing never happened, but a colleague did some tests and optimizations and a different encoder and the movement is now good enough for the moment.

Position Control jitters around target position
Next question ;) Again using Command 65, i'm moving to some target position. Works so far, deccelerates, crawls to target (depending on Ki and MaxI). As soon as the Target position is reached (the position error changes its sign), RoboClaw suddenly speeds up a little bit, overshooting the target (e....

Re: Command 65 (Buffered Drive M1 with signed Speed, Accel, Deccel and Position) always moves to 0
Looks like some parameter problem. Now that i have set a valid min and max position it works.
