Installed RatRig extruder now I get mcu errore

After installing the new extruder Beta2 from RatRig and attaching all the wires I get a mcu error saying it can not find my EBB42. Checked all the connections but it seems ok. What should I check. I tried to reinstall from zero and but after saying it wanted to upgrade the Manta it failed. I turned off and on but I stil get the mcu error.

Solution:

Ok got it to work with the MAX , now I'm getting a coorect reading. heater_pin: toolboard:PB13 sensor_type: MAX31865 sensor_pin: toolboard:PA4 spi_bus: spi1...

attach your printer.cfg

I have to change from Biqu probe to Bl Touch Extruder and the Fans Option 'microsteps' in section 'extruder' must be specified this is the error i get now. What I do know if the EEB42 is working or not. When I did the update right after the install I got no errors. Trying to reinstall I get this message what's best to do? I did a fresh install had to Flash Manta M8p and EDD42 in DFU but all went well, or so i thought. I attache my logs because now when I turn on the printer my BBB42 does not light up and I have a serial error.

Can some please help. I also tried different USB Cables.

looks like you haven't done the initial configuration and editing your printer.cfg https://os.ratrig.com/docs/configuration#initial-configuration

Some thing is strange , when i turn on the printer with the EBB42 plugged to the power supply the two lights do not turn on like they should. If i discconect power from the EBB42 and use the power from USB (with jumer) they turn on and I can Flash the EBB42. etc. Now if I take out the jumper and plug back in the power supply (checked voltage is 24V) and USB always connected the light are off and the board seems not to see the EBB42. here is my printer.cfg as long as I use power from usb no mcu error but if I use power supply I get this mcu 'toolboard': Unable to connect Once the underlying issue is corrected, use the "FIRMWARE_RESTART" command to reset the firmware, reload the config, and restart the host software.

I also tried anothe brand new EBB42 same probems

blacksmithforlife•9mo ago

you always have to have the USB connected to the EBB42 regardless of what is powering it

Yes that I know like, I said the lights do not turn on If I yes the 24v connector to the EBB42 . That looks like my old config this is the one I have now after new install.

printer.cfg

Synapsis•9mo ago

this is with out power from USB

Synapsis•9mo ago

The other times had no real problems installing. I knew something was wrong when the Bl didn't probe when I turned on the power. Changed EBB42 now they turn on

blacksmithforlife•9mo ago

you need to uncomment line 272

Synapsis•9mo ago

ok thanks Question I'm getting a MCU 'toolboard' shutdown: ADC out of range, the sensor is connected , now if I say i'm using the Rapido should it now the sensor type or do I have to add it?

TheTik•9mo ago

you'll have to tell it Put this under User Overrides:

[extruder]
sensor_type: PT1000

Synapsis•9mo ago

Thanks but still get the error I have the bed sensor type as EPCOS 100K B57560G104F , which is the bed I bought from RatRig.

TheTik•9mo ago

are we talking about the extruder, or the bed? Or is this a new error

Synapsis•9mo ago

It would seem the extruder as it says toolboard I was just asking about the bed but for now I don't know if it is working seeing it keeps shuting down. Controlled the connections and seem to be ok.

Synapsis•9mo ago

With my previous hotend i had the EBB42 set as a PT100 with sensor_type: MAX31865 which is on the EBB42 and should be more accurate. So I set the EBB42 as a PT1000 with the jumpers.

blacksmithforlife•9mo ago

You need to follow the Rat-OS wiring diagram if you expect it to work without modification

Just use it as a regular thermistor

Synapsis•9mo ago

Ok I feel stupid thanks will try it.

blacksmithforlife•9mo ago

Sorry, not trying to make you feel stupid, just pointing out there is documentation and it will help for you to read it

Synapsis•9mo ago

😄 Thanks so muh that was the problem, wanted to use the MAX as the said it was more accurate. Should have followed the guide. Only problem its reading 129° .

TheTik•9mo ago

If its reading 129 I think its assuming the wrong thermistor type

Synapsis•9mo ago

I have not added any sensor type blacksmithsays it should work without modifications.

blacksmithforlife•9mo ago

No, I said to use a regular thermistor port. You still need to specify the correct thermistor type as TheTil said

Synapsis•9mo ago

Ok will do. Thanks Ok added [extruder] sensor_type: PT1000 but I get aMCU 'toolboard' shutdown: ADC out of range.
