CNC Skipping G Code Instructions

So I tested the looser timings but I still have the oscillation in rpm that seems to be independent of timings.
I have of 10,000, 10,000, 5000 and 5000.

I'll change my accelerations since I am using Imperial. A setting of 15 should be good right?

I have any faults trigger the motion.feed-inhibit hal command. If there is a better way, let me know.

From here, I'll send a response if this issue happens again.

Now I just need to fix what I assume is a PID tuning issue. When running at 20 in/min, it has hiccups when performing linear movements. When running at greater than 50, it overcompensates way too much when I stop moment causing oscillations.
This was not an issue before I started messing with my settings. I'm not sure what changed. My P value is still at 1000 for my x and z.

Thanks for the help so far.

For the wiring, Both my x and z are on the TB2 header.

X Axis

PUL+ Pin 3
PUL- Pin 2
DIR+ Pin 5

Z axis

You might try single ended connections
Some drives require quite high current on their inputs

Single ended connections:

I would leave the PID settings alone (at 1000 for a 1 ms servo thread)

Note you can also reduce the ferror settings in the ini file to see if the
motion problem is in the hal/stepgen side or the drive hardware or interface
side. I would suggest 0.001" as min_ferror and 0.005" as ferror

Turn out my oscillation issue was that I had accidentally changed my stepgen_maxaccel when viewing the calibration page...

Thanks for the help. I will update if my machine misses a rapid again.

I found the issue.

When my z would start a rapid, there was a very small chance my power supply would cut out for about a 1/4 second.

This was enough for my machine to miss the rapid but for me not to catch it.

I have a switching power supply for each motor and a separate supply for my mesa card so I didn't realize this originally.

I didn't step down the max amperage in my driver config so it would pull roughly 140% of the rated current.
