### Basic Information:

Printer Model: Zonestar Z9V5 with M4V6 hotend and BMG extruders  
 MCU / Printerboard: stock board for the MK3 model (don’t remember the exact name)  
 `klippy.log` (not really applicable, I’m having hardware trouble)

_Fill out above information and_ **_in all cases attach your_ `klippy.log` _file_**. _Pasting your_ `printer.cfg` _is **not** needed_  
_**Be sure to check our [Knowledge Base](https://klipper.discourse.group/t/about-the-knowledge-base-category-table-of-contents/6228) and in particular [this](https://klipper.discourse.group/t/how-to-trouble-shoot/6326) and [this](https://klipper.discourse.group/t/how-to-ask-for-help/6327) post**_

### Describe your issue:

…I have gotten a mixing hotend working with Klipper, but for some reason whenever I have it set for only 1 extruder to be used it’ll skip while extruding through the hotend, I’ve tried at 10mm/s and 5mm/s feedrates and it’ll do that. doing a mix doesn’t cause this.

I’m using BMG clones and I have the rotation distance set to 7.71 and the gear ratio at 50:17 on all 4 of them. I’ve tried silk PLA and PETG to the same result
