Using MatterControl. 1.5, which told me there was a printer firmware upgrade available. Installed it and ran into a scale problem. Eventually resolved that by reverting, exporting the EEPROM, updating again and importing the data. However, I am now wondering if the scale is correct, or if I am misreading the sample prints provided by MC. Are the spec'd in MM? Are the values seen in the Edit window of the part meaningful in the physical realm? That is, if X shown a 25.4 should I expect a part to measure 1 inch in the X axis? For instance, the calibration circle object seems to want to be 5.51 inches in diameter, yet the part created is only about 2.7(mumble) which works out to approximately 1/2 scale as I see it. If that is correct, it suggests the "steps per inch" in the EEPROM need further tweaking.
