So I finally got myself a 3D printer (delta with Marlin firmware) and got my test print looking somewhat cube like. The problem I have now is that the X & Y are 1mm too short (10% off)(Z is correct).I read online that I need to change ‘DELTA_DIAGONAL_ROD’ but do I need to make this higher or lower to get accurate results?I also saw in the same post that ‘DELTA_RADIUS’ controls ‘flatness’. I was wondering if ‘flatness’ is how straight the lines are on my cube?Any help is massively appreciated! http://ift.tt/2awnR7r
