Slave motor lag during default program run
Posted: Fri Apr 09, 2021 6:57 pm
I have an issue with the slave motor lagging during the Buildbotics logo program during testing. The program generates some rapid movements of the Y axis which appear to go beyond my max velocity based on the joystick speed.
It only seems to lag a few times during that simulation and only when the extreme rapid movement of the Y axis happens. Both motors and the gantry seem to be tracking equally throughout the rest of the program.
I don’t have any mechanical binding with my machine. I don’t have coupling slippage. I haven’t scoped/triggered anything but I don’t feel it’s an issue with missing pulses (speculating).
When I manually move the axis via joystick, it doesn’t happen. I move it many times back and forth and several 100 mm, and it doesn’t have a problem. It only happens during the logo program.
Any suggestions?? I don’t want to stress the bearings any further before trying a solution. Thanks.
I really like this controller and I’m excited about getting things off and running!
