We did all the testing on the bench that we could. Now we need to swap out our old Arduino grbl solution for the fancy LinuxCNC solution. We started on Monday with one axis at a time. We had to tweak some directions and homing parameters as expected, but it was going smoothly. Of course, then we had to revert back to the Arduino version because some important people needed to see it operating. An hour of wiring later we were running on the old system.
Today we started the swap over to the new system again. And it was immensely painful. At first only 2 of the 8 axes worked. Very perplexing. We noticed that the case was at +24V so we chased down a loose wire from the swap. However, now none of the axes are functioning. We decided to pull out the o-scope and look at the pulses...
Attachment not found
The pulses are lined up with each other on most of the axes, but in the same direction so they look like they'd cancel each other out. Some of the axes don't seem to be sending pulses at all, though, so we're really confused. Any clues as to what has gone wrong between 2 days ago and today? Any help is appreciated.
