The horror... the horror....

people like you mark, matt, tesseract and countless others make this forum indispensable. without the amazing volunteers id be lost along time ago.
I hope i can contribute like this as I continue to learn and improve.

Edit: there are alot of people i didn't mention but printedsolid defiantly deserves a shout out he one of the best "monks running the show"

 

fixing this problem is reallly REALLLLY simple.
Lets talk real fixes. no more bitching.

Do you have auto leveling or not?

@Island Bill

 

Collin, I did the work on the printer. My time bills out at $50/hr. That's time I could have been billing out on side projects easily. Don't go in the deep water if you don't know how to swim, lol.

 

Sounds like my boss. Saves $1000 on parts to spend $10k on payroll.

 

If by auto-levelling you mean that feature in MatterControl then yes, and I've used it. I've also levelled the bed on a bench, placed a water-tight skirt around it, and put in water to see if the bed is warped. It is. If you think a 3-point auto levelling reference can fix that, believe me buddy I'm all ears. Let's hear it.

 

Yeah, you're right about that Mike. Had I known what horror awaited me, I would gladly have spent the money on an Ultimaker II. I guess that's what I get for buying American .

 

Well it's what you get for not doing adequate research. You can have expectations as a consumer, but they should be based in reality. The only way to know they're realistic is to research and see what other consumers have experienced.

If you had asked us before buying the printer I would have steered you away. Same way someone who asks for the cheapest printer I suggest the printrbot metal.

If you want a printer with large build volume, low cost, and modability, the R3D doesn't have a comparison.

 

Sounds l

Ya... Exactly.

Dude fix your attitude. You want help or not cause I fixed this same problem on my own printer and so has everyone in this thread it's easy but stop with the snyde remarks it isn't doing you any service. I was just like you my first couple fixes angery and frustrated. You'll find more people will help you if you are nice.


Anyyyyyyways I do not mean the auto leveling in matter contoll I mean this
RoBo 3D Printer Automatic Bed Leveling:

If so this is a matter of just increasing your z offset factor if not...you can fix this with a screwdriver by screwing the bolt that trips the zendstop closer to the end stop.

See Mike, I'm about to hoist you on your own fkn petard pal. I gave a detailed set of criteria and reasons why I chose the Robo3D in this very thread and foremost among them was print bed bed size. Sorry to have to rub you into that but as you say, that's what you get for not doing your research.
The precision of the parts I require is not aerospace caliber. I just need a printer that fkng prints a medium quality output with normal maintenance. As I have already said MANY TIMES in this thread (there's that research thing again, Mike), the Robo3D I received does not even do that. I recommend if you're going to shoot your mouth off at me about what I have and haven't done, you do YOUR research about what I have and haven't done.

So @Island Bill
I just told you how to fix go fix it. Test it and tell us what happened. Or pls leave.

 

He's not looking for help from us. Just someone to put as a scapegoat since he can't be sure his criticisms are heard by team robo.

I dunno, but if I paid myself $50/hr I'd have made a smarter investment like the MakerGear M2

Though now I'm really just poking the bear.

 

I still want to help this guy if he will fu**** let me. Lord

 

LOL! Ok, ok. B--O--3

 

Actually Mike, I thought you might be a good conduit into the guys at Robo 3D, so I decided to yell in here so they would hear there. lol

Now, it DOES appear that I may have solved the problem.
Collin: I love ya man, but it was not a software levelling issue, something which I think the photos proved outright. I mean, how could it be that a print an inch wide would print well on the loops and also on the perimeters, and yet start barfing on the infill? I'm sorry for my acerbic replies, but it seemed to me that this much was evident from the photos. But thanks for pointing me in the direction of souped up auto bed levelling.

Mike: I owe you an apology -- not for what I said, but for allowing you guys to get under my skin so bad. I was/am very upset at Robo3D for their lack of courtesy and responsiveness. But that's not your fault.

Ok, I think -- I don't know for sure yet, but I think -- that the problem was a loose wire to the active cooling fan. While inspecting everything with the printer turned on, I noticed that the fan cut out a time or two when I touched the wiring bundle. After a little bit of tedious prodding the wire, I found a spot on the hot lead that reliable cut out the fan when I touched it. So I cut the wire, tinned it, soldered the leads together and shrinked it. The photo below is the result taken at exactly the same point in the print of the photos I posted earlier:


My theory is that the cooling fan on the print head cutting in and out was causing variations in the nozzle temp that were not enough to trigger a temp alarm, but just enough to mess with the clean consistent extrusion of material.

Any ideas?
