does that 65mm include the heat sinks? Also, which length of extrusion is the X and which is the Y? I'm trying to figure out where the space is lost between the ~300mm available and your final figure of 190mm build area.
I'm certainly planning on building this - I think the MendelMax is a bit overkill and conincindentally, you posted design this a day after I started thinking about a simplified Z design!
Is there any reason you'd recommend against expanding either the X or Y dimensions? I will probably alter the
design a bit to allow for 10mm rods on the X and Y just to make sure they have a bit less flex.
Thanks so much for posting this - I'm sure I'll be adding derivative parts soon!
