EBB42 v1.2 via DFU

I am trying to configure an Octopus 11 with an EBB42 v1.2 toolboard but cannot seem to get the toolboard into DFU mode. I have connected the toolboard to the Pi via USB. I have inserted the jumber on the VBUS pins. I have rebooted the Pi several times. There are no illuminated LEDs on the toolboard. The RatOS configurator stays at "Waiting for DFU. Am I missing something? Do I have a bad toolboard?

Temperature error ADC out of range

Hello all, around every third print I receive a temperature error from klipper. ADC out of range or Heater extruder not heating at expected rate It seems to read wrong temperatures from the PT1000 sensor or tells me that the temperatur is out of range or couldn't be reached fast enough. ...

Solution:

I changed both USB cables to 3.1 with 10gbps bandwidth and 18W. The system is still stable after two longer prints. I'm going to observe for some days and check resolved then.

Some command to retry wifi connection without reboot

I've recently "upgraded" my home network to Ubiquiti, and it seems like it has given me unreliable internet. This, of course, isn't Ratos's problem, but it seems like the setup is quite impatient with trying spotty wifi connections, and really quickly reverts back to creating the RatOS wifi setup hotspot. Is there a way to tell ratos to instead just keep trying for a bit longer, without needing to reboot the entire rpi? A slight tangent: Any ideas why my rpi4 can see multiple copies of the same network? Yes, I have multiple hotspots and a mesh network, but it seems like if i pick the wrong one, it refuses to connect. Looks like I need to randomly pick the base station's wifi to connect (which is quite far away)?...

Idex Preheat Tool before actual printing movements

Is there a way to preheat the tool before it is actually used? I always have to wait (around 15-30secs) till the hotend reaches the desired temperature (coming up from the standby temperature) and continues printing. Is there a available macro or maybe a script to sort this out?...

VAOC camera + crowsnest causing causing system freezes (chamber camera fine)

I have been able to use the VAOC camera successfully for dozens of prints over the last 2 months. Just yesterday the OS started freezing up. It's taking 10s per keystroke to SSH in, mainsail won't load. Then it seems to crash after a few minutes.
When I reboot it's accessible for about 30s. Which is long enough to systemctl stop crowsnest which instantly unfreezes the system. If I instead watch journalctl logs, there is no indication of anything wrong. It all appears normal until it freezes and I get disconnected. If I comment out the VAOC camera from crowsnest.conf, everything works fine including chamber camera. If I leave VAOC but comment out chamber cam, it seizes up. So definitely something wrong with the VAOC camera....

Error when starting prints with 2 Extruders

Everytime when I try to start a print that is sliced with 2 toolheads (1 for the actual object and 1 for support material) this message comes: Error evaluating 'gcode_macro START_PRINT:gcode': jinja2.exceptions.UndefinedError: list object has no element 1 When the file is sliced with only one extruder working everything works just fine. My slicer config matches the given one on the ratos documentation. I tried both prusa slicer and super slicer but the problem remains....

Fly SHT-36 Pro issues

Im trying to figure out how to use an unsupported Fly-SHT-36 Pro Toolboard. I selected the Fly-SHT36 during configuration, and have successfully overridden everything except for one problem.

Setting up Schedueled Maintenance Notifications

I'm running a 3D printing company (PSL3D.fr), and I'm working on making my printers even more reliable in the long run. I'd like to manually set up maintenance reminders or protocols (e.g., apply PTFE oil to linear rails every 100 hours), and then copy/paste the same setup across all my machines. At the moment, I’ve got 4 RatRigs and 8 Prusa MK3S. I noticed that Ratrig OS is creating some kind of file in the History section, but I’m really not great with code... If anyone could give me a hand with this, I’d be more than happy to share our full maintenance routine—based on real-world experience in a production environment!...

mcu 'mcu': Unable to connect

I purchased a back-up board as a safeguard. I had to manually install the firmware on my back-up board because it wasn't being detected during the configuration process. I would like to know why one board would be detected and not another? I would gladly pay RatRig to test these boards before sending them out. Also, I'm receiving the following error message on my back-up board: Klipper reports: ERROR mcu 'mcu': Unable to connect...

gcode command PROBE already registered

Installed firmware for first time and received the following error message: gcode command PROBE already registered

Solution:

I resolved the issue by reinstalling the firmware and instead of selecting 'None' for X axis accelerometer and Y axis accelerometer, I selected 'Integrated on Toolboard'.

Help with RatOS for Pellet Extruder.

hi. i am building a pellet extruder with 3 heaters and 3 k type thermistor(using max6675) connected to octopus board using ratos. Since the thermal mass of the extruder is too much, it takes some time to heatup. But as soon as i heatup within a few seconds ratos stops with this error "Heater extruder not heating at expected rate". How can i go around this?
