I have been through 3 so far and I’m not very happy about it. I got a color print head (sometimes be found much cheaper) and was hoping that swapping out the chip that is glued with one from a black printhead would work but it did not - the machine threw an error code.
The last two heads I installed I canceled the purging. I figure it is just using up life of the printhead. The only drawback is it prints black and eventually fades out. I don’t really care about the color though.
I just finished printing out a mold for a cylinder head. Hoping to pour the casting this week.
