Anycubic Mega S must have upgrade. Klipper and TMC2209 drivers for TriGorilla board

This time I decide upgrade my 3d printer. It's very old model by Anycubic - Mega S.
The printer base is very strong and reliable, but software and motor drivers could be better.
This will be just another one video about TMC2209 drivers upgrade. As well as Klipper for TriGorilla board.

You're back! 🎉👏 Nice upgrade, is like having a new printer.

Hi, I am currently right at the same stage of replacing the stock drivers with BTT TMC 2209s, in my Anycubic i3 mega ultrabase (upgraded to S with the extruder kit from anycubic itself). Just a question, is reversing the motor housing in the board necessary? Thanks for sharing!

[@zhadlun]

Yes. There is 2 ways, one is physically reverse connector, another is to reverse it in firmware itself. I choose to reverse it directly on a board, it’s pretty easy to do. Otherwise your steppers will move in opposite direction.

I used your config as I'm also using TMC2209 but get this error: unable to read tmc uart. Any ideas? Thanks

[@zhadlun]

My drivers connected with UART as well, if you does not made this wiring. Just remove sections [tmc2209 stepper_]

[@impoze]

@@zhadlun okay, as in the whole section defining the TMC2209 stepper Z and Z1?

[@zhadlun]

@@impoze yes

[@StephenScicluna]

Any chance I can get a copy of your klipper printer config

[@zhadlun]

Yes, sure. Here it is github.com/mtoy/anycubic-mega-klipper/blob/main/printer.cfg
Just please check port numbers, I had switched z and z1 motor connectors on my printer from factory

[@zhadlun]

And also bltouch ports, as well as uart connection for stepper drivers

[@StephenScicluna]

Thanks will let you know how I go just bought a second one to mod with klipper

[@hp_workshop]

@@zhadlun do i have to flip the connectors with this cfg ?

[@zhadlun]

@@hp_workshop yes, but you could change config just a bit to keep them without flipping. Just add/remove “!” Before each stepper direction port name.
