Hi Mike,

This has been an interesting evolution of the last couple of years during development. It started as Arduino based (RADDS based) but then migrated to PlatformIO on Atom using the MBED framework,

I'm now using Visual Studio Code but with the MBED command line compiler. Using MBED OS2 since we don't need a multi threading operating system and the code overhead associated.

Only running on a LPC1768/69 at the moment. It the only hardware I have for development.

For the TMC2209 a module to configure the driver on start-up would need to be written. I have done this for the MCP4451 digipot on the Makerbase MKS SBASE which uses these I2C digipots for current control setting.

Thx Scott.
I have several controllers for my 3d printers.. Mega, Due, Re-arm, mks-base (a 1768 but needed in a delta) and mks-pro + TMC2209. All in vsc with marlin. In the moment i'm on the pro's with the facinating tmc's. I love their way of controlling the steppers. Nearly silent.
I was wondering if there would be a way to use those drivers for chepo small cnc's.
Good job.
Mike

Hi Mike,

I have a Bigtreetech SKR v1.3 which can use the TMC2209's. I might need to get me a set to try out.

Unfortunately the Pro used a STM32F407 chip that I have not played with yet. But at 168 MHz even high step rates would be great for the TCM's.

I intend to use one of my set-up on a CNC router at some point. Just too many projects...

Hi Scott
Yes, much to many projects. The pro is very nice but misses until today the usb2sd driver.. So you can not download the new .bin file. For cnc i stick to linuxcnc only. And mesa, as only fpga stepping is in my eyes constant enough. But for cheep projects paralle interface (pp or rp-io) with a small interface for such chips as tmc 2209 coud be a solution. Plus a small independant sm32 to program those tmcs. Thats why i always keep an eye on lcnc-pi4 projects.

I'm really impatient !


Any reason for not try to use ethernet like recent mesa card ?
