I'd start by looking at the physical signals. You'll probably need an oscilloscope to monitor the step signal, but direction can be monitored with a simple meter. The direction signal should be high when moving one direction and low when going the other way. Problems could be with the assignment of the pins for the stepdir module (steppin/dirpin), the setup of the GPIO pins and pinmux on the BeagleBone (the pins you are using need to be configured as GPIO outputs), the wiring to the stepper drivers, or some issue with the signal levels between the Furaday cape and the Leadshine drivers. -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
