Getting skips in my extruders if extruding 1 color through a mixing hotend

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 and in particular this and this 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
