I am getting the following error when I try to update the Firmware for the Wash or the Cure.
“Error while dropping to boot loader.”
I get the same. While in that error message, just unplug the cable on wash/cure and plug it in again! For me this trick works all the time.
Thanks! I’ll try that.
I think there may be a timing issue watching for USB device changes - I found the only reliable way to get it to work on my (Windows) machine is…
Start update process
When wash/cure display blanks (it has changed to DFU (boot loader) mode), and updating is NOT being performed - ie. 20 seconds and nothing happening on the updater window
Unplug power from wash/cure unit
Hold front button down and reinsert power, for me the updating process starts
Then I found the update process wouldn’t finish properly after changing back from boot loader to normal mode, so a quick unplug and re-plug of the USB cable (not power) does it.
I think I tried just the disconnecting the reconnecting the USB on its own the first time but didn’t do anything - maybe I didn’t and that would have been enough, try that first!
I remember there used to be a problem with USB ports and sleep / power management timeouts in windows …we used to have to turn off the “let windows put your device to sleep” function in device manager hub/power management tab for each hub
I should have mentioned that I was running the updater on my Mac. I’m not sure if that make a difference in the process.
I will not be able to try again till Monday.
sorry im an idiot …just scrolled all the way up saw your mac screenshot…one thing i can think of if you have a new TB port mac is swap your port or dongle… i have had devices not like the combo video/usb/power dongles but did like the “usb only” ones and vice-versa… and other times liked one port over another…shrug…also can try with a powered hub or not… sometimes matters ,… some devices hate going though hubs.
Not at all! The interface cues are easy to miss.
I have the new M1 Max MBP. It only has USB-C for I/O, so I was using a Belkin powered hub for USB-A, but it was not powered up, since I use it for my mouse, and it works fine like that. I will try it powered up next time.
Thanks!
Did you have any luck?
Yes! I updated the firmware today. Unplugging and plugging it back in got it to work.
Thank you so much for your help!

Just like my case! Glad it worked for you too! It’s a Formlabs easter egg I guess
