I also had to replace the print head twice.
I purchased two Raspberry Pi cigarette package sized computers, and set one of them up to run the printer and give me a webcam view, and the other I set up as a personal VPN for my home network so I could securely remote in and look at the printer printing (to see if I needed to shut it off)
I had never done anything like either of those things, but got them both to work, so...It was valuable to me.
Very cool!! I admire your creativity and perseverance.
The anger issue is something many of us deal with in life. I was constantly criticized and often humiliated for small things growing up, and it led to lots of self-criticism and hearing those ‘voices’ of criticism in my head every time I made a mistake - even as an adult. I’m over that, mostly, but it was an inner voice I had to learn to ignore.
