Hey guys, I’ve got a buddy with two CFOC2’s - but one is dead. Anyone here got an old CFOC2 they’re willing to sell?
Thanks!

Thanks!
I’ve got two that I bought from you and never used I’d sell both if you/your buddy want them!
Excellent! I’ll send you a PM.
Hello there, awsome project with theese FOCer’s.
I tried following the guide of ordering from JLCPCB but im getting an error with the BOM file and CPL file.
(The below parts won’t be assembled due to data missing.
Q1,Q2,Q3,Q4,Q5,Q6,J1,J2,J3,J4,J5,USB1,P4,P5,C39,C38 designators don’t exist in the CPL file.)
Could someone confirm that this is correct?
Thanks
Yes, that is correct. These parts need to be ordered seperately from LCSC. Q1-6 are the large fets, J1-5 and P4-5 are the connectors and C38 - C39 the bus capacitors. Also, make sure to use the files from the development branche. This is where you can find version 1.0 GitHub - shamansystems/Cheap-FOCer-2 at Developer-Branch
thanks for the reply Charclo, ill try make an order again from JLCPCB and LCSC
Hello, i soldered Cheap focer 2 myself, i thought it was the cheapest and the easiest option for me. I made it according to 0.9 github files. I encountered some problems:
Battery voltage is wrong in VESC tool, motor doesnt spin at all, even during setup wizard, also no faults.
I tried all firmware versions from GitHub, both 1.25 and the newest vesc tool, i tried swapping drv and stm to new ones, i desoldered voltage divider resistors to check them. Then i found cheap focer 2 1.0 GitHub and upgraded mine to 1.0, tested firmware from 1.0 GitHub too, and its indifferent.
Can anyone help please?
I also used STP110N8F6 mosfets and 358A op-amp instead of ones from BOM. Maybe my mosfets are too slow for the task?
