Somewhere I thought I had seen printbus say that the hot end should be tightened again while hot, but I can't find that. My i3v10 came with a shroud for the fan like that looks like the current E3d6 shroud (but in ABS), so access to all except the nozzle is blocked. Do I take the shroud off and just have the fan there to have access to tighten the hotend?

Could someone recommend starting hotend and bed temps for ABS?

What screw sizes are used to mount the haswell type power supply, the M3's are too loose so I am suspecting they are not metric.
