Hi, I’m trying to use my Axidraw after not using it for some time but it doesn’t connect anymore. If I run an Inkscape command I get “Failed to connect to AxiDraw.”. Even trying to update the firmware is get: “Checking to see if we have a device in bootloader mode../mphidflash Error: Device not found”
When connecting the USB cable, the board LED blinks slower. Restarted the Mac and the Axidraw but it doesn’t help.
Using a MacBookPro (2018) with macOS 10.14.
What should I do?June 1, 2020 at 9:53 am #28390
Sorry– I somehow didn’t get the notification of your post and just saw this now.
Are you still getting an error?June 1, 2020 at 10:14 pm #28391
Yes, still not connecting.June 2, 2020 at 12:30 am #28392
Since you tried to run a firmware update while you were having trouble connecting, the first thing that we need to do is figure out what the status of the firmware is.
What I’d like you to try next is manually entering bootloader mode on the EBB:
(1) Disconnect power to the AxiDraw. (Leave it disconnected until communication is re-established. The USB cable can power everything except the motors.)
(2) Disconnect the USB cable. It may be easier to do this at your computer or at the AxiDraw — either way is fine.
(3) Press the pause button on the left side of the machine.
(4) While keeping that button pressed, connect the USB cable.
(5) Release the pause button.
If this works, then the EBB should go into a red-green rhythmic-blinking “heartbeat”. If so, that’s a good sign. While it’s still in that “heartbeat” mode, try to run the firmware updater program.
When the updater program runs, it will try a few different things. It could run into one of several different errors and may report them to you. If it either prints “Firmware updated successfully” or a firmware version string like “EBBv13_and_above EB Firmware Version 2.6.4”, then it likely succeeded, even if there are other error messages.
If it does not succeed — if it does not appear to be able to locate the device whatsoever — then the most likely culprits are the USB cable, the USB port, or the computer needs to be restarted. If you’ve restarted and still see a failure to detect the device, then try a different USB cable if you have one available.
If the firmware update does succeed (or likely succeeded), your next step should then be to try again in Inkscape, and see if it can connect.June 2, 2020 at 12:07 pm #28393
Thank you very much for this detailed explanation, I found that the USB cable had a faulty connection. Replacing it fixed the problem.June 2, 2020 at 12:27 pm #28394
Great; I’m very glad to hear that, and thank you for following up. :)
