I've been working on calibrating my printer further, prints look beautiful. Perfect everything except for the X & Y dimensions
My problem is when I print an object, say 40mm cube, the X and Y measure to 39.5mm.
This is using the stock values in Marlin's configuration.h which
78.7402
So I'll go into Marlin's configuration.h and adjust them
40/39.5 = 1.0127
78.7402*1.0127 = 79.7402
I'll put that into my configuration.h for X and Y, reboot my board, issue an M502 then M500
Test print
And the perimeters come out the right size, but the infill no longer connects. I've changed nothing else, 1st and subsequent layer heights, extruder steps per mm (which are dialed in), extrusion multiplier, nothing.
Anyone have any ideas on what the problem might be?
