Hello community! 🙂 I took the adventure of installing Klipper on my Sovol SV06. On my RPi 4 I did install MainsailOS and to be honest I was surprised that most things went very well. Although I have a problem now where I am stuck for a few days. When I try to print models that have small cylinders in it, as far as I observed, the whole machine “pauses” for a short period of time, I think where the Z-seam is, which causes blobs. I was reading around and all I could find are problems in combination with Octoprint and there is the fix to use the virtual SD card mode. As Mainsail already does that I don’t know where else to look. One more thing is that when I set the speed factor in Mainsail for example to 30% it obviously prints much slower but the “pauses” don’t last longer. Suddenly I don’t have the whole klippy.log right now but there are no entries at the time of pausing (every few seconds). Of course I can get it in the evening if it would help Thank you already for any hints 🙂 ---

I am using Superslicer/Prusaslicer with same results on both. I even stumbled around that Cura issue on Github while searching 😃 Just curious, can it be a gCode problem (apart from the Cura issue) when the pause/hang duration is unaffected from setting lower speed factor in Mainsail? I just found the gCode file that gave this problem (attached). Nevertheless I will get the klippy.log in the evening.

Got the log now 🙂 [klippy.log](https://klipper.discourse.group/uploads/short-url/b4B7Ae2H0hoD18df25ojOiqEEvL.log) (913.8 KB) ---

First, you may lower the run\_current for the Z and Y steppers: ```auto ... TMC 'stepper_z' reports DRV_STATUS: 80170101 otpw=1(OvertempWarning!) t120=1 cs_actual=23 stst=1 ... TMC 'stepper_y' reports DRV_STATUS: 80150101 otpw=1(OvertempWarning!) t120=1 cs_actual=21 stst=1 ... ``` * * * And there is this: ```auto b'Got EOF when reading from device' ``` More on this here: > [@Got EOF when reading from device](https://klipper.discourse.group/t/got-eof-when-reading-from-device/6638): > > Got EOF when reading from device Background This is actually an error raised by Linux operating system (OS) of the host and only reported by Klipper. It indicated that the contact to an attached hardware (mostly the MCU in this case) is lost. This can happen when the USB port is reset or the OS thinks the hardware has been disconnected. This error often appears in conjunction with the [Timeout with MCU / Lost communication with MCU](https://klipper.discourse.group/t/timeout-with-mcu-lost-communication-with-mcu/6639/1) errors Reasons Unreliable connection between the printer-bo… ---

Thank you for your analysis! But why is the log not flooded with either of those errors when the stuttering happens every few seconds? ---
