feat: adds TMC2240 support

[pedrolamas]

Adds support for TMC2240 temperature monitoring.

Stepper disabled

Stepper enabled

Resolves #1089

[brotherdust]

@pedrolamas , may I ask why the temperature reporting is so infrequent?

[pedrolamas]

@brotherdust Temperature report from TMC2240 is only available when the driver is enabled, the other times Klipper returns null when we read the temperature - hence why you see in the above screenshots those spaces, as I was just testing with SET_STEPPER_ENABLE STEPPER=stepper_x ENABLE=1 and SET_STEPPER_ENABLE STEPPER=stepper_x ENABLE=0

[brotherdust]

@pedrolamas , you, sir, are a paragon of kickassery! Thanks for the clarification!

[brotherdust]

Also,
I updated to latest Klipper and FluidD. Didn't even have to define anything!

[brotherdust]

@pedrolamas , If I can manage to get stepper temperature estimation implemented, it might call for a differentiated label. Perhaps the driver temp should be something like "Stepper [axis] Driver" and the stepper motor could be something like "Stepper [x] Motor (estimated)"? What say you?

[pedrolamas]

Sounds reasonable to me! I guess it will also depend on how the data will be reported by Klipper...

[brotherdust]

Yeah I was reading over the datasheet a couple of days ago in preparation of this and... the implementation details of this function are pretty vague. I'm not sure if it's actually a hardware or software thing yet. Datasheet would seem to indicate that the nerd knobs are available, but it's something that has to be calculated. I'll have to ask TMC, I guess.

I am now on Fluidd 1.25, But I only see the extruder temperature followed by Stepper X:

But I have tmc2240 for all the drivers, here is my cfg file:

@eldeeb91 I assume you also upgraded Klipper and Moonraker to the latest versions?

If so, can you upload what you get from these 2 urls:

• http://<host:port>/printer/objects/query?heaters
• http://<host:port>/server/temperature_store?include_monitors=true

Note: replace <host:port> above with your moonraker host and port.

[pedrolamas]

@eldeeb91 there's 2 spaces on your config between tmc2240 and the driver name!!

Instead of [tmc2240 extruder] (with two spaces), you should have [tmc2240 extruder], and the same goes for all the other drivers!

[Mosher23]

Hello,

I have updated fluidd to latest version and was surprised to see StepStick temps in the chart. Great job Pedro!

What are your temps? I have over 100C after homing only.

[pedrolamas]

@Mosher23 I don't have my TMC2240 in production use (I currently only use them for testing purposes with Fluidd) so I don't have a benchmark here... my advice is that you jump onto Klipper Discord and ask around on #general-talk or #stepper-drivers channels.

[eldeeb91]

Here is a screenshot and it’s printing for 10 hrs:

I have also a blower fan to cool down my electronics box.

[Mosher23]

@eldeeb91 What StepSticks do you use?
I use BTT.

[eldeeb91]

@Mosher23 I also have BTT, check my configuration on my comment up #1133 (comment).

[brotherdust]

I have BTT and mine run about 100-110C if the fans aren't on.
