Klipper for AnyCubic Kobra Trigorilla_Pro_A_V1.0.4

Code repository: https://github.com/SteveGotthardt/klipper

Status: move r65 to r66 for TMC control

Attaching to target via P4 with SAM-ICE

physical connection: Atmel SAM-ICE 20 pin jumpered to P4

  • P4: Pin 1 -> ICE Pin 1 = VTref
  • P4: Pin 2 -> ICE Pin 20 = GND
  • P4: Pin 3 -> ICE Pin 7 = TMS (used by SWD)
  • P4: Pin 4 -> ICE Pin 9 = TCK
  • P4: Pin 5 -> ICE Pin 15 = RESET

running J-link commander

  • Device: Cortex-M4
  • Target Interface: SWD
  • Interface Speed: 2000 KHz

finding stuff with J-Mem

  • VTOR is at 0xE000ED08
  • which shows vector table start now at 0x8000 (was 0x0 at boot)
  • which shows stack pointer at 0x20008D10 and reset at 0x82A1 - this is for program that shipped with my board

What is the clock running at:

PLL config @ 0x40054100 CMU_PLLCFGR = 0x1110_3100 (reset is 0x1110_1300)

So it looks like 8MHz XTAL * 50 / 2 is 200MHz system clock

  • MPLLM[0:4] = 0, divide by 1
  • PLLSRC = 0, XTAL selected (8MHz)
  • MPLLN[8:0] = 0x031, mult x 50
  • MPLLR[3:0] = 1, divide by 2
  • MPLLQ[3:0] = 1, divide by 2
  • MPLLP[3:0] = 1, divide by 2

XTAL selection: 0x40054032 CMU_XTALCR = 0, oscillates

XTAL configure: 0x40054410 CMU_XTALCFGR = 0, high-drive, not ultra, oscillates

Clock division of 200MHz system clock

  • CMU_SCFGR @ 0x40054020 32 bits after boot: 0x00242210
  • PCLK0: divide by 1
  • PCLK1: divide by 2
  • PCLK2: divide by 4
  • PCLK3: divide by 4
  • PCLK4: divide by 16
  • EXCKS: divide by 4
  • HCLKS: divide by 1

TMC UART address mapping

  • Z: [10] MS1_AD0 is resistor to GND, MS2_AD1 tied to VCC
    • so Z can be addressed with [10] or [11] without trace-cutting
  • Y: [01] MS1_AD0 is tied to VCC, MS2_AD1 is resistor to GND
    • so Y can be addressed with [01] or [11] without trace-cutting
  • X: [00] MS1_AD0 and MS_AD1 tied together through resistor to GND
    • so X can be [00] (R65 placed) or [11] (R66 placed)

Fix addressing (no trace cutting, just move resistors):

  • remap X address to [11] by moving R65 to R66 (VCC) - TESTED - works!

Extruder driver on my board is MS35775, a 2208 clone

That should work. And,of course, a common ground between the boards.

Will the piZ2W have a hard time communicating over WiFi when enclosed? Maybe use a plastic cover?

@SteveGotthardt It shouldn't have issues with WiFi, if there is it should be very negligible. The plastic ABS MCU enclosure should affect the signals at all. Maybe if I have the PiZ2W right next to the 2020 aluminum, then maybe it might. But there's ways around it. You can add a U.FL connector to the PiZ2W which you can attach a Flex WiFi antenna or convert it to SMA to attach a standard SMA WiFi antenna.

@SteveGotthardt My cable from motherboard to extruder broke. I was trying to repair it, but I lost extruder connector... Do you maybe have pinout for this cable? From motherboard to extruder?

@exdablju - I do not have a pinout for that cable - I only have the mainboard (no printer)
