Sorry for the delay on a reply... I went out of town for a couple of weeks...
I'm using typical nema 17 motors. I went ahead and dropped the current a bit on the X and Y motors and haven't had any problems since. So, the combination of tweaking the acceleration and jerk and reducing the current seems to have taken care of it.
Now, I just need to start tweaking all the parameters up to find th

Thanks the_digital_dentist... The acceleration was definitely a big factor.
I changed the acceleration to 1000 and printed fine in the center of the bed at 60mm/sec.
Then, I upped the speed to 100mm/sec with no problem (other than needing to make some more tweaks for bed adhesion/part fan speed to avoid slight warping in the corners and other minor tweaks).
I've attached images of each pri

OK... A little follow up...
I printed it again at an insanely slow 5mm/sec just to see...
So far in the first 2 hours (of a long 12 hours print), there have been no issues and I'm past the point that it normally fails.
It still doesn't really explain why it prints fine in the corner of the bed but fails in the center at "normal" print speeds. But, I just want to be able to print normally (at

CuraEngine version on raspberry pi/octoprint: 15.04.6 (since 15.04 is the highest version octoprint supports for direct slicing)
Cura version on Mac for testing comparison: 3.2.1
I get the exact same problem when slicing on the pi or on the mac with the respective versions.
Here are my acceleration settings:

That makes sense. But, I did swap out the rods in case that was the problem. So, unless both the old and new rods have the same issue (which I guess is possible since they are all from the same purchase order), I don't think that's it. I don't feel any binding when I slide the carriage around manually. And, it does the same thing whether I print fast or slow. They are just 8mm rods the carri

I built a CoreXY (HEVO) printer from scratch with a typical RAMPS (Marlin 1.1.9) setup with standard 4988 stepper drivers. I'm getting a layer shift when printing parts from the center of the bed. However, if I print the exact same model in another location of the bed, it prints fine. When I print in the front right corner of the bed, I have no problems. The failures are not in the exact plac
