| | === Babystepping Via Computer === |
| Babystepping can be performed from a computer, while printing via a USB cable. This requires that your host software allows you to input g-code commands during printing - a good program to use for this is [[http://pronterface.com|Pronterface]]. In order to do this, you must enter the [[http://marlinfw.org/docs/gcode/M290.html|baby stepping gcode commands]]: M290 ZX.XX, where X.XX is the distance that you wish to shift the print. Positive values will increase the first layer height, while negative values will reduce the first layer height. | Babystepping can be performed from a computer, while printing via a USB cable.

These buttons are accessible from the printing status page (only visible while you are printing from a USB memory stick via the LCD screen). **[[a5:lcd-firmware|You can download community LCD firmware for both the A5 and A3S printers from here]].** |

| | For information, babystepping via the LCD issues the command G91, then a G1 Z0.025 or G1 Z-0.025 and finally a G90. Therefore babysteps are of 0.025mm at a time. (G90 and G91 just change the positioning method, relative or absolute) |
