reef-pi :: An opensource reef tank controller based on Raspberry Pi.

[T-MIKE]

Been very busy with new home stuff , covid19 Ppe stuff and everything in between. The new place gets hotter than past place and I decided to deploy fans and test out cooling control in reef-pi

I need to do something similiar with the Chinese black box I have right now. the fan doesn't turn off by itself since I'm using reef-pi to control it so I need to hook up the fans to go through the reef-pi also.

 

[Des Westcott]

What did you have plugged in them?

Various stuff. Return Pump in one, Skimmer in another. Heaters (2 x 500W units. Yes, I know :eek: ) Lights (165W unit)

Been very busy with new home stuff , covid19 Ppe stuff and everything in between. The new place gets hotter than past place and I decided to deploy fans and test out cooling control in reef-pi

these are 12v fans with two level controls.
I have two pico tanks one with fans clipped on the glass and the other like this

The in glass setup blocks some light which is why I preferred this one

printed this 3D printed fixture to easily mount the fan on my makerbeam made tank base

the 10x10 mm square hole slides in the beam that mounts light. It has two channeled grooves to tuck in the fan

Pretty happy with the setup. Albeit it can use some iterations of improved , but for the time being it can bring down a degree within 3 minutes

Very cool Ranjib.

I see you've got some serious Elephant Foot going on there on that print. I saw the Cura 4.6.1 update has just been released with new settings for initial layers. Chuck Hellebuyck mentions it in his last update and promises a video on it soon. The new expansion settings seem to work well from what I saw in his last video.

I focus on helping new users get started with 3D printing using mostly sub $500 lower cost printers. I show tips and tricks so you can be successful with you...

Maybe I'm an idiot, however I'm having an issue setting up the environment.
After typing the command make start-dev I run into an error ERROR: health checker.

That is followed by a series of errors that go as follows:
ERROR: failed to get pi power throttle information. Error: exec: "vcgencmd": executable file not found in $PATH

I have attempted everything to get this environment running properly; again sorry if the question is simple and I can't see it or I'm being an idiot., however any help would be much appreciated.

Soooooo.. I'm an idiot and figured it out.. I think lol

Best suited would be your own board you designed for this exact configuration :p But I'd say your best existing option with the least amount of modifications would probably be Michael's Goby board. Since it comes set up with 2 pH connectors already, you wouldn't need to modify or split anything. Keep in mind, you'll need to get 2 separate pH interfaces, one for each probe.

i came across the reef pico baseboard/hat? any idea who makes it and when will it be available? also for that one if i wanted to do the ph probe what do i need to buy?

That would be @theatrus, his build thread for it is here. As far as availability, it sounds like he's had some COVID caused delays, but is still making progress! I believe it would use the standard double-junction pH probe with a BNC connector all the other builds use.

That’s benign And expected in non-raspberry pi environment , and should not impact . Let have these development type discussion in slack

Thank you for the link. I’ll go through it. I have not tuned my printer since the initial setup. I use 0.8 mm nozzle and print all my functional stuff using it. So far it has done the job. I definitely want to tune it , reconfigure with 0.4 mm nozzle and mod it for petg. I have to just find the Appropriate time. May be once the pandemic work settle down. I think the spring vegetable gardening work also sucked up lot of time (in a good way :-) )

 

[Ranjib]

By the way, I’m really tempted to add a driver for one of these irrigation timers (orbit or bhyve ) in reef-pi. What do you think ? Good idea? Bad idea ?

Do you know if the atlas ph board is needed? Or just the probe plugged into the baseboard?

You've got the Ender 3 right? Me too. I'm using a 0.4mm nozzle and PETG with no modifications. Same profile as PLA, just nozzle temp up to 230-240 (depending on make of filament)

That Chep guy has a whole lot of Cura print profiles for use with the Ender 3 (Best, Good, Medium and Rough). I get very good quality parts when I use his Best quality profile. Prints at 0.12mm layer height, so it isn't quick.

The stock thermistor and ptfe tube will withstand petg temperature?

Some other things to look into, other than a leveled bed, is making sure your e-steps are calibrated correctly as well as getting your flow and retraction. My ender was over extruding out of the box and when I checked e-steps it was good but over. Once you get that puppy dialed in, it's kind of a beast for the $$.

Anyway, I think that's enough unsolicited advice. ;Dead

 

[Urtoo]

I am looking to get another 3d printer.
Should I get a Ender 5 pro, or is the extremely Ender 3 pro perfect for us tinkerers.
I currently have a Delta

I did the Estep calibration during the initial setup. I think I’ll go through it again when I get started with petg , or my prints get bad enough that i can’t use the for the functionality they were intended for

Ender3 pro I would say. 5 has some better things , but it’s pricier and with smaller community, My friend has 5 and he seems to have more issues (subjective )

PETG is a giant pain to print. Took me a while to get it to where prints were usable. Temp tower to get the best temp, then get retraction right. I had to turn the fan down to max of 30% and slowed print down to 50 mm/s.

Prusa, it just works right out of the box. PETG is easy.

Prusa, it just works right out of the box. PETG is easy.

at 800$ and more elaborate assembly. I dont know how its easier. Its definitely more sophisticated and versatile for more material types and high precision. I actually plan to get another cr10 or prusa. The build volume of cr10 is pretty compelling.
