Quick way to Raize Z-Axis
New to the Mk3 and the Prusa World. Going well at present but one thing I find a nuisance is that I cannot find a way to raise the extruder way up the z-axis without rotating the key.
Is there a one or two button press "get out of the way" function.
Useful when I want to remove the bed plate or to fiddle with something on the extruder.
Thanks
David
Re: Quick way to Raize Z-Axis
You probably already knew this- but if you press and hold the knob, it switches to the Z-Axis move function. Then just twirl the knob to get it up out of the way. Doesn't get much simpler than that.

I also use Octoprint to control the printer and move axis. Never used Pronterface (that comes with the drivers) but you should be able to do it from there too. Or modify your gcode so that at the end of the print it goes wherever you want.
Re: Quick way to Raize Z-Axis
Thanks for the quick replies. Just trying not to wear out the rotary control.
Far more bits likely to wear out though I guess.
What a great printer this is.
Re: Quick way to Raize Z-Axis
You could also add code to your ending gcode script to move it up and out of the way?
Using this code you could have it raise 25 mm after each print (can adjust whatever value you like)
G1 X0 Y200 F7200 ; home XY axis
G91; Set to relative mode
G1 Z25 F7200; Move up 25mm
G90; Set back to absolute mode
Or if you use this instead (don't use both) it'll always move up to 180mm (again can adjust to whatever value you like)
G1 X0 Y200 F7200 ; home XY axis
G1 Z180 F7200; Move up 180mm

Hi,
Simple question : if you used this script at the end of each print and your print is arlready close to the top did it force to the frame ? like for the Z axis calibration to aline both rodes ?

Not sure off hand. I believe the firmware should stop it at max height and not let it go any further but I rarely print things over 100mm tall so I've never checked.

Yes, up to a maximum of 210mm which is the firmware limit.

Or, you could just add a Z height to the line that moves the extruder home (instead of the F code)...i.e. G1 X0 Y200 Z100 (or whatever height you wish.
RE: Quick way to Raize Z-Axis
For a while I was using a quickie .gcode file to raise the Z and move the printbed forward. I kinda just quit using it, no particular reason.
