I have been trying to research in to the buying a off the shelf reedy to run printer v a genuine prusa v building my own using hiwin rails. I'm tempted to go with the prusa mk2 but quite fancy building a nice frame using single arms from extrusion running on some hiwin carnages so I can go a fraction larger.

How hard is it to get a diy printer super reliable like I read about off the shelf printers?

My way of thinking is there is no point in saving $1000 on the printer if it costs $2000 in time messing about trying to set it up.
