Anet A8 printer, Github Marlin, Repetier Host, Cura slicer
Just setting up printer and printed 20mm calibration cube from Thingiverse. X,Y,Z & E not too far off but not quite right (centre hole was oval not round) X19.5mm, Y19.5mm & Z20mm.
Followed Youtube calibration help and updated firmware to Marlin. I ran several iterations of request travel, measure result and tweek stepper settings (M501,M92xxxx, M500) Live Die Repeat...
When I now print the calibration cube I get X25mm, Y20mm & Z19.5mm.
Could the issue be with the firmare being upgraded to Marlin? The cube was sliced by Cura and I have used the same file for all of the prints. When I stop the print and ask Repetier to move the steppers the distance is as they should be for a 100mm travel.
