MMU Update
A few months ago our printer stopped working. The MMU unit wouldn't move correctly when starting the printer. We just stopped using it, We are wanting to get it started again. I updated the m3 unit and then needed to update the MMU unit. The MMU update failed. I tried and think I succeeded in erasing the MMU EEPROM thinking that might help. The update still failed.
I have attached the error log.
We will really appreciate any help we can get on getting our printer up and running again.
Thank you.

RE: MMU Update
try flashing using a windows machine - the flasher and linux can be problamatic
RE: MMU Update
I recently had this issue as well. The only way that I could successfully flash what to reset the MMU right before I hit flash.. There is a really small window that seemed to work.
Also there was a "bug" that was present in Ubuntu that prevented flashing ... something with modem ... I will try to find the culprit when/if I have a chance today.

@david-a66
I will try that. I have run parallels on my mac to have a windows environment for years with out a problem but since there last up date a few days ago I have had to bring up a back up once and think I will need to do it again today. It has been sitting for about 40 minutes with out starting. So it may take me a day or two to try using the windows flash option.

@willima-m26
When you say reset - do you mean the factory reset process?
Thanks for any suggestions and help.
We have had such a great time with our printer. Want to get it going again.
RE: MMU Update
No sorry I should have clarified that. The button beside the usb port on the MMU.
RE: MMU Update
Yeah Thank you both for your help. I used a windows version of slicr and the reset button and got the new firmware loaded.
I really appreciate your help. Made my day.
