### Basic Information: Printer Model: Prusa i3MK3S+ MCU / Printerboard: Einsy Host / SBC: RPi 5 ### Describe your issue: It has happened many times today that in the middle of the print jobs, filament was not being extruded. For the last few prints, it printed one or a few layers and then no filament was extruded. What is the cause? I unloaded the filament and loaded again. Same problem. Tried different filament. Same problem. Not sure if related but in the past, this seemed to happen more likely when I left the filament loaded in the printer unused for a few hours before printing again. Why doing so increased the chance of no filament being extruded mid-print? ---

Sorry I forgot to mention that I am using E3D Revo 6 High Flow Nozzle 0.4 with high flow heatercore. One strange thing that I noticed the past few days is that sometimes as the tip of the filament entered the extruder, it got automatically is guided in. However, sometimes I have to manually push it by, say about 5cm, before it was guided to extrusion. What is wrong? ---

[no\_extrusion\_klippy.log](https://klipper.discourse.group/uploads/short-url/8eLGSw9ZFxTWUFLkyTyDKEdfyCL.log) (2.2 MB) Did a hardware maintenance but the problem remains. Hope it is a software issue. ---

Have you tried with a higher motor current? BTW: How did you estimate that huge amount of driver parameters? Do you know what they do? Another notice: What do you use the `diag1_pin` for in the extruder? > ```auto > #diag1_pin: > # The micro-controller pin attached to one of the DIAG lines of the > # TMC2130 chip.

Hello, I have not tried with a higher motor current. I did not estimate any driver parameters and I did not assign diag1\_pin myself. Everything was set up automatically during installation of Klipper via the following method: [GitHub - dz0ny/klipper-prusa-mk3s: Structured Klipper config for Prusa MK3s 3D printer](https://github.com/dz0ny/klipper-prusa-mk3s) ---

He does not provide support. Tried in the past already. ---

Great! Throwing some stuff into the world and then not want to be responsible for it. 🤮 I suggest to go a different way to adapt the MK3S to Klipper. ---

🤔 I never had issues with that config. You could probably take the TMC2130 parameters from the below official config and put them in your current config. > ---

Thanks. So I just put it in ~/printer\_data/config? Currently, the “einsy-rambo.cfg” file is located at ~/printer\_data/config/klipper-prusa-mk3s/mk3/einsy-rambo.cfg Will it be automatically removed or I have to delete it. ---

You could do that, but I would just remove the TMC sections from your existing config and copy and paste the TMC sections from the linked config into your config. ---

I don’t see any TMC sections in ~/printer\_data/config/klipper-prusa-mk3s/mk3/einsy-rambo.cfg but there are a few in :~/printer\_data/config/klipper-prusa-mk3s/mk3s/tmc2130.cfg. So I just replace the original ones by the ones listed in [config/generic-einsy-rambo.cfg](https://github.com/Klipper3d/klipper/blob/master/config/generic-einsy-rambo.cfg) ---

> [@printeruser](#): > > but there are a few in :~/printer\_data/config/klipper-prusa-mk3s/mk3s/tmc2130.cfg Just remove the line in your printer.cfg that includes it and then paste in the TMC2130 sections from the config I linked previously. ---

I see that in printer.cfg, it includes a tmc file from that github site I mentioned. I pasted value from the config linked but it became worse. Now it failed to extrude in the middle of the first layer. ---
