Voron 2.4 300 Refurb

[Penatr8tor]

@TitusADuxass Do you think your experience with the EBB36 is typical for BTT CAN boards?

I have an EBB36 on my RatRig, at least I think it is, I have to check.

Anyways, now I'm wondering if mine is going to go south prematurely.

No this is not typical in my experience.

This is the first one that has gone south on me, the others I fried.

Okay, last night I went to print something in ABS, my Amazon ABS profile has dissappeared from my library of filaments!

Then - I got a klipper extruder sensor type must be defined error. I had not carried any changes to my config files.

I updated via apt and via the mainsail menu, restarted and got the error klipper reports: error option 'pin' in section 'probe' must be specified - WTF!!

I went into the config files and tried to do a search (Ctrl +f) for probe but couldn't enter more than one character in the search field.

I found the entry that appeared relevant, and changed  the hashed out entry from probe to Beacon (still hashed out) and restarted.

This time the error is klipper reports: error option 'pin' in section 'probe' must be specified - WTF!!

 

Everything was good on Sunday and the only thing that has changed was the addition of the second filament type.

Are things being updated in the background?

If they are is there anyway of stopping this intrusion.?

Whatever is in your Moonraker.conf file is definitely getting updated behind the scenes.

[TitusADuxass]

I'm still getting this error - Option 'sensor_type' in section 'extruder' must be specified

I don't understand why, the extruder sensor type is defined in the EBB36.cfg (it hasn't changed and was working).

Can anyone see anything wrong?

[mvdveer]

I know it sounds silly, but does the EBB support PT1000?  What happens if you change this to PT100 instead? I can recall that I had the same issue and was told on discord that the EBB36 board I had, though it said it supports PT1000, did not. Just cannot find that conversation but will keep looking. I swapped back to a SHT36.

Also try:

# PT100 / PT1000
sensor_type: MAX31865

Might need to set the pull-up resistor to 2200

[Penatr8tor]

I was going to say, try setting it to "Generic 3950" just to see if the error goes away but...

Brilliant minds think alike. @mvdveer

[TitusADuxass]

Gents,

The EBB36 that I have does support PT1000, it has the 4 DIP switches in the lower right corner.

It was working fine last Sunday. 

[TitusADuxass]

I'm flashing the CB2 and starting from scratch.

I'll get it working and then disable any updates by hashing out the relevant moonraker lines.

@mvdveerI'll also set the pull-up resistor to 2200.

[TitusADuxass]

Fixed it!!

I reflashed the CB2, installed everything I needed via Kiuah.

Installed Beacon.

Mainsail still gave me the same error.

I deleted everything below the:

#[include moonraker_obico_macros.cfg]
#*# <---------------------- SAVE_CONFIG ---------------------->
#*# DO NOT EDIT THIS BLOCK OR BELOW. The contents are auto-generated.

And the problem went away.

[TitusADuxass]

I had to drop the PID and Beacon sections back in. I couldn't save the PID results and the Beacon didn't have a model to load.

It still doesn't explain why it happened in the first place.

[mvdveer]

Just happy you got it sorted. Never a dull day with this hobby. I rather there be dull days 

 

[TitusADuxass]

Since I reflashed the CB2 I no longer get random communication errors when homing. 

I've also got PETG dialled in on it, it's now back to fire & forget printing. 

[TitusADuxass]

And I've now got a clicky-clacky door - why haven't I done this mod before!?

I agree, this is a must-have mod!

Yes I have. Now I'm making one for the 330.

[Penatr8tor]

You guys really suck, Ya know...

Clicky-Clack door on order.  

Might as well finish up my refurb with a nice mod.

I also ordered new top and side panels. The old ones had heat related fogging that couldn't be clean away. They're fine actually but for ~$40 I'm getting new ones.

Surprised it took so long. But you won't regret it. One of the BEST mods out there - should be included in the standard build.So easy to do and works just great!

I have similar issues with the second SB2209 (2.4r2 350mm). I manage to flash Katpult, then klipper and started working until stopped! According to vendors, BTT SB/EBB will either work for long time or die early! My first SB2209 (2.4r2 300mm) still working fine.

The upgrade from Afterburner to Stealthburner with LGX Lite v2, CAN, CNC TAP and SB2209 is running good, but I believe the stock Stealthburner setup does not cool parts enough for fast printing. Previously I had a modified Afterburner running a 5015 for parts and my PLA prints were better at higher speeds compared to the Stealthburner.

I started printing some Easter Egg Torture Test from Maker Muse and the lower nested perimeters and overhangs were drooping using PLA to a point I had to slow down to ~40mm/sec to be able to have them not interfering between the three egg layers. I printed the same with my older Afterburner setup and even at high speeds did a good job.

At this point, I do not feel going back to the Afterburner, so I am considering a CPAP, for my Voron not me lol, and trying to figure out if I should go with the BTT or Bondtech CPAP version.

@TitusADuxass You have the BTT Turbo kit; would you recommend it, and any pointers?

Btw, I will be using PWM speed control only. Do I still need to use the Adapter with the Wago connectors or go directly to the brushless controller (24 VIN, GRD,  and +5, +S, GRD)?

Finally, anyone have tried Crown Cooler instead of the Stealthburner? It's not as pretty as the Stealthburner but I am sure we can add the LEDs to it

It's a good cooling solution, but it is very loud. Even turned down to 40% cooling it is loud.

I used this https://www.printables.com/model/620071-ultralight-stealthburner-cpap-main-body. It's a nice solution.

I think a bigger external fan would probably provide the same cooling but might not be as loud. I have a 120 mm fan from my vz330 kit RSCS that is doing nothing. I going to try and develop a duct for it.
