Hello @KillMek ! [image] KillMek: since its both printers stopping at the same time. On the same model gcode?

Good morning, Two different models, just both take around 36 hours to print. One printer is setup with Bowden the other is direct drive so even retraction, pressure advance and flow rates are all different.

Your error is: Timeout with MCU 'mcu' (eventtime=61369.534085) Transition to shutdown state: Lost communication with MCU 'mcu' See Timeout with MCU / Lost communication with MCU for more details. Unfortunately this kind of error is hard to come by. What is striking: max_accel: 700.000000 max_acc…

I see, I guess Ive never seen what a good Klippy log should look like. any ideas on how to keep the printer from changing the Maxs constantly? I use Orca slicer usually. I wonder if my maxes in the slicer are conflicting with the klipper set maxes. When I get home Ill make sure they match. Any other…

[image] KillMek: any ideas on how to keep the printer from changing the Maxs constantly? I’m not too familiar with Orca and my initial attempts left a mixed feeling. But I would also guess that the values do not really match to your printer as it hardly survives a velocity of 2000 mm/s and I …

Definitely no virtual machine. Laptop is running Linux as its only Operating System. I think the max square velocity is set to 5 in my slicer, maybe I forgot to set the printer.cfg back after I was done experimenting. Ill make the changes and report back how it is. Thanks for all the help!

@Sineos , Sorry About the late response, one of my Printers had the Heated bed die in the middle of testing. I am happy to report that fixing the constant acceleration changes seems to be the fix. In Orca slicer there are 2 different sections to select acceleration speeds and Maxes, the printer kept…
