Printrboard Not Connecting or Printing Untethered From SD

3D Printing 3D Printers

I honestly do not know what to do as I have searched all of Reddit and Printrbot support for answers and tried everything. I have a rev f5 Printrboard (latest) and it out of the blue will not connect or print untethered via USB. I have tried power cycling , pressing and holding the reset button as well as trying to print from SD and nothing will work. I am really confused as well as the board was working earlier today. Please feel free to ask more information as I am not quite sure what is enough information in this case and I have any info you may need.

Cheers,

Hi Alex

What printer is this on? What hot end do you have? Have you tried to reflash the firmware?

Ian

Hi Alex,

same questions of Ian. You need also to check all wire connections of your printer. For instance if the thermistor isn’t connected you can have this kind of problem.

I have had a printrbot for a while now. I have found that the micro USB port can get loose and will not connect the unless you have just the right angle. The remedy is to carefully crimp the port back down to a tight fit. Then shut it down and reboot. Be sure not to wiggle the port or line. The other is the cura software package may not be set to the correct printer type. Un install then reinstall making sure you have the right interface type set in cura or whatever slicing program you are using. Printrbot line is a good line but comes with some bugs to work out. Hope that helps.

I have a printrbot simple makers kit model 1405 on a ubis 13s hotend and I have not reflashed yet. I have also checked all connections.

I have a printrbot simple makers kit model 1405 on a ubis 13s hotend and I have not reflashed yet however I have pressed the reset button and rebooted following the advice of a printrbottalk forum post however the board didnt flash or do anything upon pressing reset.

I will definitely try both things that you said especially because this was spontaneous. I will make sure to keep all of you updated.

it won’t show any signs as the reset is pretty instantaneous. Here’s some docs for flashing depending on Mac or Windows

Is the green light on, on the printrboard?

Yes it is.

Would the reset wipe the firmware. Either way I will try flashing it.

A reset wouldn’t flash it. I think I flash is in order though…! Let us know how you get on!

Will do!

Is there any visible burns or damage to the board? Most notably the mosfets, capacitors, PCs traces and connectors

No and there was no “magic smoke” coming from the board either.

Make sure that when you put the SD card in, the file you want to print is auto0.g not autoo.g . Also be sure that the file isn’t in any folders.

Unfortunately it sounds like you have some fouled wiring or your board has died and gone to the cloud…

I did that yet the hot end didnt even get hot and nothing happened.

I am very happy to say that my printer is fixed and I am back in business!! I would like to thank everyone who gave me advice especially Ian for writing the very comprehensive guide on flashing firmware as that was what I needed to do to fix this issue I was having. Once again thank you all for helping me fix my Printrboard in an extremely fast and timely manner as well as saving me 80 dollars!!

Great news, this is what communities are for. Glad you’re back in business. These things happen - it’s not rocket science - it’s IT!

Get back printing and all the best!

Steve
