Introduction:
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.
Step 1
Connect to OctoPrint and open the Terminal tab .
Step 2
Tick the Suppress boxes.
Step 3
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.
Step 4
We are going to alter the Z offset with just gcode.
Rev1 (M851)
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.
Rev0
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]
