Hi Everything was fine in the past weeks. Today I got this problem that port closed. Same to this thread Blackbox issue Please help *port closed* I got this problem about a week ago. I just did a restart for the laptop and then it worked fine but today it doesn't work.
Hi, I've had that same problem and it is been very frustrating for me. I have tried many things to resolve this issue, and to date, the only thing that works for me is the following: 1. Turn off the power supply feeding the black box 2. Turn off the power on the black box 3. Disconnect the USB cable on the black box 4. Turn on the power supply feeding the black box 5. Turn on the power on the black box 6. Plug in the USB cable to the black box When I have performed those steps, the black box is recognized by the computer and the OpenBuilds software can then connect to it. I don't know if you'll have the same luck, but that is what has worked for me. Rod
Usb led colors has no deeper meaning. They just indicate rx/tx read the FT232RL datasheet if you want to know more More likely miswiring somewhere. Disconnect everything but the USB cable. A wrongly wired limit switch can short out the 5v rail and even damage the board. Refer to docs:blackbox:faq-usb-connection-failed [OpenBuilds Documentation]
As if flashed successfully on the Mac it shows the controller is still alive. Did you test with only USB connected (no other wiring) on the mac yet? Any known events from when it worked till it didn't? Known shorts, accidentally disconnected a stepper motor while power was on, power surge, metal chips fell into case, yanked out USB cable damaging connector?
yes, I tested with only usb without any wires but nothing change Nothing happened recently. I ran as a normal. All wires are connected properly. No shorts or accidentally disconnected
None at this time, seems something damaged it, from here its hard to tell you what happened to it Just adding to the above: Normally IT troubleshooting steps: tried different USB cable? tried different pc?
So what I do? I have not made any extensions or changes after assembly the lead cnc before 2 weeks. Do I need to contact the store?
I tried another 1 usb cables and 3 pc 1 windows that I was working with it and now says “flash failed” port closed. The other 2 are mac pro and iMac both of them “flash complete” but also port closed
I apologize for the many questions. I am zero in these electrical and technical things, so I ask a lot. Thanks for your quick response and for providing all the solutions.
I install the UNO Arduino with friend help. It is connect perfectly, but still I want to install the limit switch and the probe.
