Wow you have a video for everything needed for my 0.2 build, even the expander board. Thank you for your time making these videos, highly appreciated!

Hey Greg- it was great getting to say Hi to you at MRRF yesterday. My daylight on a matchsticks arrived while I was at the fest, so ordering an expander now :D

Awesome video very good info also If you add temperature_mcu to your config you can read the temp right off the built in sensors on the pi and mcu board.

Great video! Glad you like the expander! By the way - you can also fetch mcu and pi's temps by adding this in your printer.cfg file. [temperature_sensor raspberry_pi] sensor_type: temperature_host min_temp: 10 max_temp: 100 [temperature_sensor MCU_Board] sensor_type: temperature_mcu min_temp: 10 max_temp: 100

Thanks for watching! Also, awesome tips to get board temp readings- I probably should've mentioned that as a possibility in the video (I hadn't yet added those, and will do so)! Thanks for pasting the settings.

Power input 24VDC for the exp board is also available from the SKR Vin terminals (as an output) which is even closer to the expander board.

@0:50 They struggle because the chip inside can overheat and the fan periodically shuts down. Especially the DGSTIME brand.. removing the sticker might improve that a little

Do you have to reflash firmware if you're adding klipper expander to an already running mcu/rpi?
@GregsMakerCorner
@GregsMakerCorner 3 жыл бұрын
Hi Kevin, yes- it is a good idea to reflash the firmware on the Klipper Expander because it may be out of date, which was the case with mine. There is no need to reflash your 3d printer mcu or do anything with your raspberry pi.

Hey Greg, where did you get the documentation for installing/firmware updating this board in Klipper?

Chris, great question! It is in the Voron-Hardware repository. I will add the link to my video description as well. Here is the direct link: github.com/VoronDesign/Voron-Hardware/tree/master/Klipper_Expander/Documentation

How did you get Klipper to treat those thermistors as temp sensors? I have mine as extruders but would like to replicate your method
@GregsMakerCorner
@GregsMakerCorner 3 жыл бұрын
Hey Dominic, thanks for watching! You can see the syntax for adding the thermistors as temp sensors right around the 21:51 mark or so. The syntax is basically a [temperature_sensor nameofsensor] heading, and then sensor_type and sensor_pin entry underneath that.

would there be any changes needed if using 12v rather than 24v fans, such as with the nevermore V4?
@GregsMakerCorner
@GregsMakerCorner 2 жыл бұрын
Nothing significant- the klipper expander can be used for 12v just fine. It will provide the same input voltage on all the Vin pins.
@antok86
@antok86 2 жыл бұрын
so does all fans plugged directly into the expander have to be 24v if its directly on it?
@GregsMakerCorner
@GregsMakerCorner 2 жыл бұрын
It would have the same voltage as whatever you power it from. So if you use 24v as input power, then it would be 24v for the fans.

Is there a solution for the ADXL345? what do you think about TurboCan?
@GregsMakerCorner
@GregsMakerCorner 2 жыл бұрын
For ADXL345, I don't think there is a good solution with the Klipper Extender. However, I just connect my AXDL45 directly to the Rasp Pi. TurboCan looks really interesting! I had not heard of it until you mentioned it. I will have to look more into it. Thanks for watching and commenting!

Does anyone else have the issue that a reset via a restart command seems to do nothing / lead to a not connected board? I always need to powercycle my expander or press the physical restart button....restart_method command seems to do nothing for me

Awesome video as always! Don't the skr mini e3 v2 and the pi already have temperature sensors in them? I've added a couple entries to my base config and am getting temperatures for both without additional thermistors.
@GregsMakerCorner
@GregsMakerCorner 3 жыл бұрын
Thanks for the comment and watching! On the board sensors absolutely- using the built in temp sensors would be just fine to get a back temp reading. I thought about that as well, but ended up using the extender since I was already adding it for the fans. There might also be some spare pins on the skr or pi that could also be used along side with the thermistor. It’s great to have the flexibility and options.

Ok, so could you run a second. Extruder with this?
@GregsMakerCorner
@GregsMakerCorner 11 ай бұрын
Unfortunately, it won't support an additional extruder as it doesn't have any stepper drivers on it. If you are looking to do that, you could add a CAN Bus board, or the LDO Picobilical (which uses USB, and is a great fit for a Voron0.2). There may be some other options available as well depending on how many motors you need.

@@GregsMakerCornerAh, yes, good point. No stepper driver. CAN is a no for me. I am a Canbus apostate. Spent 3 weeks on that expensive nightmare. I ended up using the 14 pin harness minus cable chain as an umbilical. I made a custom mount on back of orbiter and orbiter has hartk board and a buck converter for my 5v fan. My toolhead is xol-toolhead, which recommends a 5v fan. Dumb toolhead board way to go imo.
