    So after building a four DOF rig i seem to have a problem with the motors with hall sensors going past there limit and once this happens the motor rotatates slowly until i stop it with a PSU cut off ,having then to go in to the SMC3 program and rotate the hall sensor it so that the green and blue line are both together again before all is well again so my question is what is the best way to limit the range and stop this from happerning again Until now i thought that this program was just to test the system i now think i understand that it does program each of the the motors momement , so what to reduce to try and stop the over run .thanks for any help
    Les.

    The purpose of SMC3 is hardware control and configuring related settings, including limits and PID, the first 2 posts in the SMC3 thread cover SMC3 functionality and settings: https://www.xsimulator.net/communit...3dof-motor-driver-and-windows-utilities.4957/

    PID is a somewhat complex topic, here is my analogous gentle introduction, which includes links to more accurate and hardcore explanations, depending on how far down the PID rabbit hole you want to go, while written with JRKs in mind the general analogy is the same: https://www.xsimulator.net/community/faq/a-laymans-analogy-guide-to-pids-pid-tuning.219/

    What motors do you have and how many amps are they ?

    How many amps is your power supply

    What type of motor drivers do you use ?

    Hi .Thanks for your reply, the morors are from motion dynamics 12volt 23 amps the power supplies and 50 amp with moto monster cards i have included a screen shot on my SMC3 settings these at the moment are for all four motors . thanks Les.

    As you are using moto monsters you really need to test them for faults before use, see the FAQs here: https://www.xsimulator.net/community/faq/monster-moto-testing-before-use.158/

    Two of the moto cards are the genuine ones two are the cheap clones all four seem to work well ,the roll and pitch are one sparkfun card from RS components (real deal ) and the other is a clone the problems i have had are only related to the pitch and roll that seem only to happen if i increase the amount of travel and the axis limit having never altered the limits in the SMC3 program perhaps this will inprove matters ?
