I just received and built my MOOZ-3, and everything seems fine for from a hardware perspective. I was able to calibrate the printer and start a single-colour print. However, the colour mixing interface did not seem to work at all. When I looked again at the manual, I realised the UI pictures were quite different, so I checked what firmware version the printer was running.
The printer itself showed itself as running something like 0.4.1 (according to the touchscreen).
So, from the Dobot site, I downloaded:
Touchpad firmware for MOOZ-1/2/3 v1.1.0
MOOZ Firmware for MOOZ-3 v1.3.6
The touchpad firmware installed successfully via the SD card. However, the interface looks as though it’s intended for the MOOZ 1 and 2, despite the download description mentioning MOOZ-3 as well. It’s possible of course that the firmware is looking for some kind of signal from the printer controller firmware in order to determine what to show, but either way, the touchscreen can no longer operate the printer at all!
Updating the printer controller firmware has been less successful. When I insert the SD card with the MOOZ-3 v1.3.6 bin file, and power the printer on, I get the following message on the screen:
SD Card Update…
No Find File
So, at the moment, I can’t use the printer at all! I’ve emailed support, but haven’t heard back yet - I’m hoping I just need some alternative firmware. If anyone has any suggestions for what I might try in the meantime, I’m open to ideas! Here are some other things I’ve tried:
Connecting directly from the PC to the printer via USB, using a serial monitor, Arduino IDE, Repetier, and avrdude, in the hope that maybe I could control the printer hardware, or try uploading the firmware directly. However, I it’s possible the USB connection is actually to the touchscreen controller, not the printer controller. I didn’t get a useful connection.
Using different SD cards for the firmware, just in case.
Putting the firmware on a USB drive, since I was originally able to print from USB - printer didn’t recognise it.
Renaming the .bin file to a later version
Thanks in advance. Wish me luck!
