I'm a bit of an idiot, how do I load the software onto the control board?

Changed.

Changed.

I’m going to change it to 0.333.

Edit- YAML looks syntactically correct to me. I think we can try this one.

@LosTyger - Ping… Have you had a chance to try that config.yaml on your board?

63

OK. Sorry for the delay. I will describe, prob in more detail then necessary, in the hopes that I don’t skip out on something important.

I saved the text from the thread above into a Notepad document, saved as config.yaml.txt. I uploaded that to the board using the FluidNC local files option. I changed the name to config.yaml. Then I made sure, on the FluidNC settings, that the Config/Filename was set to config.yaml. I think this is all ok, but when I look at the FLUID NC Settings, Config Items, the name says TMC2209 XY Servo Laser, and not “Table ZenXY” as the config.yaml in the thread, so maybe I haven’t done it properly?

I’m not sure what I should do next. The config file seems like it is loaded, but using the buttons on the Dashbaord, I can’t get the steppers to move at all. That, of course, could be a lot of different problems, but that’s my current status.

64

That might-or might not- have introduced some issues.

Can you copy/pase what you get in the terminal window if you send the following command:
$SS

Edit- reboot the board before you send that.

Very weird.
Delete the existing config.ysml, then reboot.

After that we have to get the valid .yaml onto your board.

Did you unzip the config.yaml.zip and the transfer the enclosed .yaml file to your board?

The forum will not let me attach a .yaml , which is why i had to .zip it.

69

OK, I deleted what was there, then uploaded the .yaml. It is the file after being unzipped.

Any chance its trailing spaces causing this?

71

Do you see trailing spaces unexpectedly in the .zip I posted above? Weird.

I’m creating a fresh copy with a different editor. The only difference I think I see is that there isn’t a newline at the end of the original.

@LosTyger - try this one out:

config.yaml.zip (1.2 KB)

Edit- same work flow. Delete the config.yaml or config.yaml.zip if they appear on your board’s file system.

Then upload the extracted config.yaml.
Then reboot your board.
Then send the results of $SS

72

No I didn’t look at the .zip. I just know that’s caused some major issues in the past for some config files so wanted to throw it out there incase it could help

I don’t think it likes the uart being defined under the tmc_2209 which lines up with the error messages. The LR3 config defines the uart in a separate section. The tmc_2209 section then references it by uart_num. The sample I saw has it defined like you do but it doesn’t seem valid.

The documentation lines up with what I’m suggesting.

Try this one. This makes the change I mentioned.

@jeyeager rocks! The syntax for my original attempt was based on the example for that board that I found- but obviously wasn’t correct. Jason has made this look better so we’re not horribly misconfigured.

So, the configuration syntax is now valid, but the UARTs on the TMC2209s are not being recognized by FluidNC.

That means we’ve misconfigured something and I’ll need to go study Bart’s board design documentation to see what next to try. Most likely the UART or address is wrong in our config for this particular board’s TMC2209 implementation.

Were really getting close now.
I won’t have time to look at this for a few hours, but will take another look when I can.

78

I’m still looking over that config.
I do notice that there are not just one, or two, but 3 contributed ZenXY config files for the Bart Dring Pen/Laser 2209 board located at :

It’s probably worth trying these one at a time and see if any of those work for you.

I’m not sure exactly how 3 contributed ZenZY configs made it there- but they did.

Note that to test these you either need to download them and rename them to config.yaml when you put them on the FluidNC file system, or you need to choose those as the running config.
(I’d just delete the config.yaml off the board, then upload a renamed config.yaml.)

I’m suspecting that we have something wrong with the UART definition for the TMC2209s.

The pen/laser board uses a much simpler addressing scheme for the TMC drivers (That’s why it only has 2!). Boards with more stepper drivers have to use a different method, and I’ve only ever worked with those boards (e.g. the V1 Jackpot).

The file names are

Pen_laser_2209_Zen.yaml

pen_2209_zenxy.yaml

zenxy.yaml

Remember that with Github you need to click the download button to download them rather than display:
