XY Start Print offset setting in Cura?

[DaHai8 74]

Is there a way to set the X & Y start offset for printing that is different than the (0,0) X/Y Origin?

Like setting margins on a paper.

Let me explain:

I have an JA Aurora A3 Pursa I3 printer (a mighty fine printer IMHO). The way it is set up, the print head origin X&Y is actually off the bed by 30mm each way. I kinda like this in that there's no way to slam the tip into the bed when it returns to origin if your bed it not calibrated. Plus when you are unloading/loading filament, it doesn't just dump all over the print bed to be cleaned up later. But I digress...

The way the manufacturer gets around this is by specifying a print area larger than the print bed. But then you have to remember not to place anything too close to the X/Y Origin or it will miss the bed.

So I was wondering if there was a way to specify print area separate from print origin in Cura, eg:

Print Origin (0,0,0)

Print Area (30-210,30-210,0-180)

(X,Y,Z)

Then the layout display in Cura would just show the printable area on the grid...kinda like margins on a paper.

Thanks!

You can use disallowed areas to "fix" this. Its not the best solution, but it should work.

I'm looking through the (very old) docs and searching the python code, but I can't find any references to Disallowed areas.

Any help where to find this setting?

I guess this is in the BETA version of the software, because the only information I can find on it is for 15.06.xx Beta.

Sorry, but I think I'll wait until the final release to try this.

The old Cura also has disallowed areas, but they might have a different name. They are called like that in the beta.

Hello, got the same printer, did you find a solution for this?

I know this an old thread, but I had the same issue and discovered a solution. Using the manual controls to auto-home and move the X and Y axes, I measured the front left corner of my print bed (where the tape starts) at Y+30mm X+25mm from the end stops. In the Cura machine settings, I then modified the start gcode to move to that position before printing and set it as the new zero. After doing this, the prints are centered. My start gcode is now:

 

G21 ;Set units to mmG90 ;Absolute positioningG28 X0 Y0 ;HomeG28 Z0 ;HomeG1 Z15.0 F3000 ;Raise to dodge bed screwsG0 Y30 ;Move Y to 30G0 X25 ;Move X to 25G92 X0 Y0 Z15 ;Set this position as the new X/Y zero;Standard extruder setup belowG92 E0G1 F200 E1G92 E0

wigginx: Yup, that's pretty much exactly what I do as well.

No disallow areas required and can also be set in other slicers.

I used this information, with some adjustments. I have the glass bed, with clips, two on "bottom" and two on "top", and one on "left" and one on "right" of the bed, I placed the printer nozzle to have the 0,0 at 14mm/14mm, and that gave me about 207x212mm of clear print space. I print a small line to the left just to make sure that there is filament into the nozzle when print starts. It is outside the virtual rectangle, and does not touch any of the paper clips.

 

I used this start g-code
