This article will demonstrate how to alter your start height. For the purposes of this article we will use OctoPrint, but this method should work with most control software.
Connect to OctoPrint and open the Terminal tab .
Tick the Suppress boxes.
Send a M503 command to your printer's current settings.
You are going to need to look for the Z offset value for your printer.
- M2: M206 ZXXX
- Rev 0: M206 ZXXX
- Rev 1: M851 ZXXX (Rev 1 has a touch probe)
Make a note of what the Z value is.
We are going to alter the Z offset with just gcode.
Altering the Z offset numbers in a more positive direction will move the bed farther from the nozzle.
eg. M851 Z-10.50 would be closer to the bed than M851 Z-9.50.
Altering the Z offset numbers in a more positive direction the bed will move closer to the nozzle
eg. M206 Z-10.50 would be closer to the bed than M851 Z-9.50.
* Search for the M206 in the text that pops up. The Z value is your current Z-offset. It will be something between 11 and 12 mm * Add to the offset to move the bed up at Z = 0 and lower it to move the bed down. Send your new Z-offset value to the printer with “M206 Zxxx” and replace xxx with your new value. * Finally, send M500 to save the value
M3ID T1 offset
This offset is adjusted by the the Z value of M218.
In the same way that you use M206 to calibrate T0, you can use the M218 to calibrate the T1 extruder assembly, using M218 T1 Z[X]
