Klipper user here with 3 different machines with many mods installed… klipper help is available to my limited knowledge…
If you need help ask away, I’ll do my best 
Welcome. I’ve only heard of Klipper, so I’ll be paying attention to learn what I can.
Well welcome to the club 
Klipper is amazing and MUCH easier to master then marlin, between Cura and klipper… My printers have never worked as good as they do now

Ive never used Klipper either, but am eager to learn about it.
Also your printers look great :).
Questionn for @NicholasW, what brought you to the world of klipper first? Over say smoothieboard and away from Marlin?
@NicholasW
Nicholas, the Printer making the BioShock Print…
It looks like an Ender 3 Series with Linear rail upgrade and a Voron 2.4 Extruder, Please Define
Also, Do You like it?
I came to klipper because of recommendations from @PJprincefpv from 3DPC…
He told me to jump marlin ship last year… but I was still kind of new and learning marlin at the time…
Now that I’ve made the switch… I’m never going back unless no choice

Hey Keith…
My ender 3 is a total Frankenstein…
It’s current list of guts:
Ender 3 pro printer,
BLV linear rail kit,
Dual z steppers,
Skr pro 1.2,
Tmc-2209 on dual Z and dual E(prep’d for dual extrusion),
S42B’s on X and Y,
BTT Smart filament sensor,
Raspberry Pi 4b 4gb,
BTT pi tft50 display,
Phaetus Dragon hotend,
Voron Switchwire Afterburner with BLV mount,
Voron Switchwire Afterburner dual extrusion head,
Voron Switchwire Afterburner direct drive head,
I’m sure there’s more… Lol
And tbh… it’s the best thing I ever put on my ender…

Most Excellent!!
I loved the idea of the Skip direction BTT S42B’s, i’m stil waiting to try them!!
Do you Really like the Phaetus Dragon and DragonFly hotends? How’s your experience with them?
If you really like them please add to the Summer 2021 Wish list!
hey, hope im in the right spot with this.
i have a modified prusa mk2.5s bear with skelestuder and am changing my board from the mini rambo to a bigtreetech skr pro 1.2 with tmc2209’s. i am pretty excited to switch to klipper and have been doing alot of research and i believe i have successfully flashed my board and installed octoklipper on my octoprint session. ive been working on my config for about a week now and just cannot get it to connect and send back a ready signal. always this:
Printer is not ready
The klippy host software is attempting to connect. Please
retry in a few moments.
Klipper state: Not ready
the octoprint terminal shows:
Send: M105
Recv: ok T:0
repeating so im pretty sure the board is communicating. new user so ill add the log file once i can attach and ill add a pic of my board setup in case somebody spots a jumper in the wrong spot or such. i worked through all the errors from my config till i just got the printer is not ready. im just not sure where to go from here.

The first thing I’d look at is the terminal settings on the host computer.
What operating system are you using?
If it’s Linux, check:
lsusb
You should see something like:
Bus 003 Device 041: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter
Also, using:
dmesg | grep -i serial
Do you get something like:
[389467.035048] usbcore: registered new interface driver usbserial_generic
[389467.035062] usbserial: USB Serial support registered for generic
[389467.036873] usbserial: USB Serial support registered for ch341-uart
Basically I’m verifying that the computer “sees” the serial port on your Octoprint box.
If you can confirm that, with a terminal program like the one built into the Arduino IDE (others are similar, but this is the one I’m familiar with), you should be able to select the appropriate USB port.
Once you have the appropriate port, verify your baud rate matches what octoklipper ie expecting. I don’t know what it is, but you can test it by just going through the various the baud rates and trying to connect. That’s usually the big hang-up.

mcu ‘mcu’: Unable to connect is what im getting now.
heres what im getting from the lsusb:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 012: ID 0483:5740 STMicroelectronics Virtual COM Port
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
im not sure how to get to the terminal settings on my pi?
this is what i get from the dmesg | grep -i serial:

at this point most of this might be over my head, i see that device 12 is the chip from the skr pro so it sees it right?

Have you gotten your serial device ID and pasted it into the printer.cfg??
Yes I have updated the serial in config after inserting sd card and powering the board. I’ve heard the skr pro can be picky with cards. I have a cheap kooton micro sd. I will pick up a quality micro sd on the way home from work and attempt another flash to rule out the card as my issue.
Hey, what did you do in your printer.cfg for the S42 steppers?
Totally new to this and having a hell of a time finding specific info for my frankenEnder!
