NOTHING Working

Hello there,

I built your “printer”, the instructions are amazing and its a really easy build process - good work there !

BUT it does not print :slight_smile:

  • I installed Repetier 0.56 on Mac and it worked for w ahile, while i was calibrating the printer …
  • All of a sudden it brought up 5 comands waiting
  • ok I used a powered USB Hub
  • I cheked the speed is 250000
  • I checked ALL Parameters 5000 times
  • I took another Mac -> same result
  • I took Ubuntu -> same result
  • i tried to flash the board -> Arduino can not flash board - timeout
  • I made sure its version 1.06
  • I tried cura -> no
  • I tried cura on Ubuntu -> no
  • I bought a new board (well who is gonna refund that ?) -> trieb all the above again -> No
  • I checked the power supply does right Voltage and such -> All fine and Dandy but still -> NOP

So after reading EVERYTHING about 5 commands waiting, flashing the bios and anything else and putting in 100 hours plus I would love to 3d print something if your printer really does support this function…

I am completely pissed, 3 different machines 2 different OSses 2 different boards, what else can I do ?
I am a technical engineer and computer scientist for 25 years now but at the moment I could crash this thing against the wall !!!

Any help welcome, but please do not ask if I foloowed the manual or such, I did 100 hours research now, so I might jump your throat immidiately :wink:

Inbwetween I will try on a fourth machin with win 8.1 (I hate that, but maybe it helps)

Kind regards and sorry for any bad language, all I wanted is to print 3D…

I tried on WIn 8.1 Machine and guess what:

Arduino IDE can not flash (timeout)
Repetier brings a buch of commands waiting
Cura does not work it brings connecting and after a while closed, the log (ok I have a log here none on Mac) just say M105 a few times and then disconnect due to timeout…

Now I am out of ideas…

3

Just a guess, but did you already try another USB cable?

cheers,

Christian

Hahaha,

actually thats what came to my mind this morning, its the only component I left unchanged all the time …

So I will stick my hopes into this one till the evening :wink:

Any other ideas anyone ? I am really lost there …

Cheers,

Jens

e: removed some typos

If it doesnt’t work get back here.

I’m sure we can find the fault anyway.

Check the output of the power supply at the blue connector should be around 15 volts.
Check the com port for proper installation
Sorry I don’t speak Mac but on windows make sure the baud rate is 250000 and the reset on connect is set to disabled
You will find those settings in the printer settings

I did all of th above, as mentioned even further above :wink:

As said: It looks all good, and I am stuck to the hope, that its the USB cable… can not wait to check tonight :wink:

I also tested on Mac OSX Yosemite on iMac and MacBook Pro and Ubuntu on another machine and Win 8.1. I performed ALL of the tests mentioned above on all of the platforms…

At least I get a consistent, though unsatisfying result :wink:

As the only component left unchanged is the USB cable, I will test again :wink: If its not the USB cable its rather something completely unexpected and stupid or the result of a ton of bad circumstances … (like 2 broken boards or such)

I’ll update as soon as I know…

It would be a good idea to check the 5 volt regulator on the board to see if it’s over heating.
This would indicate a short somewhere either on the board or in the wiring.

9

Well…

its not the cable, so all hope is drained :stuck_out_tongue_winking_eye:

I will go on experimenting and if I do not get it to run I’ll go to the shop and give it back… I am beginning to get the feeling this rather crap than a 3D printer …

There is no heated regulator, it doesnt even connect on USB without the stuff plugged…

cheers,

Jens

Don’T give up now!

At first try the following :

Disconnect anything but power and usb from the board.
Also remove all stepper drivers.

Then try to connect to repetier.
Does that work?

cheers,

Christian

I had a small success inbetween, when I was able to update the firmware (even so I do not Know if it really did it but it looked like it …)

In Repetier I was able to turn on the fan and the light went on… (of fan as ist was not connected to anything)
After that again only frustration and nothing working…

And as none of the support here are interested I will take the printer to the shop on saturday and buy something that works …

What a shame all the hours of building and frustration PLUS the money for the second board…

Well at least I got a lot of people on my Facebook to warn about not buying one :wink:

I will give it a last test with the windows PC (I switched to my mac when I successfully updated, cause thats the platform I want to use but the 2 “successes” happened on win…)

Oh and I can easily update any arduino board on any machine here … any OS of the three Mac, Win , Ubuntu it all works like a charm…

Cya,

Jens

Did you follow my suggestions from the previous post?
I think there is something wrong in your printer wiring, causing the board to malfunction.

OK its my fault now ?

thats why the board does not work even without being wired to the printer ? Bad wiring of a printer it was never connected to ? Because before I put in the new board I FIRST connected it only with power and USB… How can a printer that is wired badly influende this ?

Do you now the feeling, when you know everything ist correct and it still doesnt work ? When you are one million percent sure you assembled it correctly ? I knew it was not my fault, even though I have to admit it also was not the board. Here is the reason:

I finally found out it works on windows (should have stayed there after I was able to flash the board) not on both of my mac, so I checked all the software components and found out that the FTDI Chip Driver was corrupted - on both of my Macs (Must be a general problem) The first board is definitley broken… may it be my fault or not I am not sure of that but I will take the cost of that, maybe I roasted it while adjusting the stepsticks…

I appreciate your help, still this was very frustrating because it was unexpected, I would have never assumed that the driver was broken on both machines. And I stick to my opinion, that this is not for people wanting to do an occasional 3D Print and if asked I would advice most of the people I know (not one or two of my maybe most nerdy friends but the rest) rather to get a pre built one or let someone assemble and adjust it for them or get it printed online. And still as this is a support forum, I would have appreciated a word from an official :wink:

I did my first print last night, so now I will have to adjust everything so I will be off looking for answers to what I belive will be some common questions regarding the adjustment, temperature and such…

Your profile says youre from Germany, what city do you live in ?

Cheers,

Jens

edit: Oh and I would like to add, that despite the troubles with the board building this was really a fun thing to do and now that its working it still feels rewarding!

No one said it’s your fault.

How should i know that?

Yes, for sure, i develop Software foa a living… :wink: (but experience shows, that if it doesn’t work there absolutley IS an error)

If i had known that the board ran on windows i had pointed you out to exactly that.
I’m no Apple guy but i read several comments about that issue.
There were also FTDI drivers for Windows that actually BRICKED chips they “evaluated” as non original FTDI!

No big deal at all :wink:
I bought this machine mainly to learn about the technology and because it’s easy to modify.
For getting prints out in premium quality atonce there are several other options, that’s true.

Near Bielefeld in NRW, why do you ask?
