Start print in opposite coner of build plate

Prusa Mini, doing some test prints to iron out some bugs.

First layer starts in the back left corner. How can I tell the PS to start in front right corner?

It would make watching the print process easier.

RE: Start print in opposite coner of build plate

To piggy back off of this: When pausing for a filament change at a layer: The print head parks in the 'front right' of the build plate and waits for me to unload etc. How can I instead have the print head park in the 'rear left' (or anywhere else it would be preferable) of the build plate to wait for me? There must be an easier way than editing the g code longhand, right?

As far as I’m aware the park position is determined by printer firmware so you can’t specify by gcode. The gcode just contains the pause command, it’s doesn’t have any position data, unless you are scripting it using the custom code option of Prusa slicer 2.2.0.

By my read of https://help.prusa3d.com/en/article/prusa-specific-g-codes_112173/#m600-initiate-filament-change-procedure

Usage

M600 [ X | Y | Z | E | L | AUTO ]

X - X position, default 211

Y - Y position, default 0

Z - relative lift Z, default 2.

E - initial retract, default -2

L - later retract distance for removal, default -80

AUTO - Automatically (only with MMU)

I can adjust the position it heads to as it reads the filament change code. My print should be finished soon, so I can start playing around with it more. Not sure if there's a way I can automate what (if anything) I find works by changing the way it posts out, but I'll let you know what I come up with

Thanks, didnt know about that.

If you do find the parameters work then instead of inserting a M600 or M601 you can insert custom gcode with the right click option so you should just be able to paste in your M600 x,y,z,e,l line instead.
