i have built a MPCNC PRIMO im using a mks tinybee with fluidnc any one has a config.yamil file

Hello, Bazy and welcome to the V1 community forums. We’d love to see a build thread for your Primo build, both to celebrate your build and to provide documentation for other users.

I don’t have a Tinybee board so can’t confirm the config- but there are threads here on the forum with some info. For example, this one:

If you do get a config.yaml that works correctly for you, it would be good to contribute that back to the forums.

hey @MakerJim thanks for your reply
ive checked this thread they using tmc2209 with uart not working for drv8825

TinyBee is incapable of using UARTs on the TMC drivers without making jumper setups manually. If you’re comfortable soldering and modifying your board it can be done, but otherwise you have to run your TMC drivers in standalone mode.

Edit to add:

The modification needed is shown here:

There are also example configs, but those will need to be modified if you go through with getting UARTs working on your board. You’d also have to modify the examples for the Primo setup.

Also to add: If I’ve completely missed your need and you’re only going to use DRV8825, I think the FluidNC configs shown on the FluidNC web page are a good start, you will need to rearrange those to match the motor/axis/endstop config of your primo.

he is using 8825s , no uart.

I am not sure of anyone using the tinybee for mpcnc. I have lr4, but that will not help you.

I am sorry.

here is my lr4, hope it helps!
together with the wiki this should get you going. I too am using 8825’s
