@t3p3tony I've tried recreating it by removing the endstop connection, stalling the stepper during homing, etc. etc. but I can't seem to recreate the same error message I've had, and the printer still runs the Z home macro flawlessly. I'm honestly quite perplexed and chalking this one up to RRF beta gremlins 😉

Thanks for the help in all cases!

Forgot to reply and close this out: running beta 2 now, seems to be alright, but the root cause was my hardware and not the controller or the firmware. A slight oversight on my end was definitely the culprit!

Cheers!

So yes the code is fetching rr_reply after each call before disconnecting.

And the 0x0c error is what shows up for the Duet Error code in the M122 output.

I've been able to work around this issue by waiting in the code until the buffer size is greater than 150, which seems to work so far in my testing, but I'm still not clear on why I'm having these issues.

What do you recommend I try next?

Recalibrated everything, and also properly meshed my print bed to eliminate issues from Z height differences across the build plate.

PA tuning resulted in the same amounts I had earlier. Also tightened down the motion mechanics of the printer to ensure that everything is locked down the way it should be. Belts are tuned to about 50Hz (9mm 2GT Gates).

I'll try out changing solid infill patterns to what @Phaedrux has suggested using Cura. Currently running some test prints to see if the issue has been resolved.

Thanks!

So I took a sliced file and randomly chose 3 different points to calculate the steps per mm. The ratio is between 7.3 to 7.5 XY steps to E steps.. Don't think they're lining up too well in terms of pulses. Still have my doubts on what's causing this, as it seems to be the result of several things lining up to create it..
