I say that because my Mendel90 of the last five plus years is currently printing out its replacement.
I have been extremely satisfied with the printer and would like to thank Nophead for the great reliable design.
A few quirks I've had with the machine are the Z axis height adjustment and Y axis belt tension.
And the X axis belt breaking twice.
Over the last 6 or so months, I have noticed the plastic starting to crack and will fail fairly soon.
(I have replacement parts to completely rebuild the printer)
Once I have the new printer up and running, I will be replacing the cracked parts, and will be
passing along the Mendel90 printer.
I am moving into an aluminum extruded frame with CoreXY mechanics.
Again, I would like to express my greatest thanks to Chris with helping me step into 3D Printing.
