Account for wipe when determining seam location

This should be very simply to add, could even make it a toggle in case others done need it BUT.

Right now when you add a wipe distance, that wipe distance will move your seam location from its intended location to X mm from the intended seam. My request is that the wipe distance is accounted for so that if I say I want seams to point to -600x and -600y (corners) that they still appear there, even if I have a 2mm to 3mm wipe distance.

Re: Account for wipe when determining seam location

This should really depend on what is causing the seam in your prints. Is the seam being caused by the vertical movement after the wiping is done or is it caused by the stationary retraction that occurs before the wipe takes place? If I recall correctly the retraction still takes place where the manually placed seam is requested. Then the wipe travels along the perimeter until the specified wipe distance has been fulfilled.

Other print settings may have an impact on seam placement...

As far as I can tell this will not necessarily happen depending on retraction speed, length and wipe distance. Also it's important to
check if "Perform retraction during wipe movement" on the Advanced tab is enabled...

Example:
Retraction speed: 40mm/s, length: 0.8mm
Wipe enabled, distance set to 0.8mm
"Perform retraction during wipe movement" enabled

Code: Select all

G1 X129.804 Y117.262 E1.0103
G1 X129.444 Y117.262 E-0.8000 F1080
G1 X129.004 Y117.262 F1080
Retraction takes place while moving ~0.36mm, another ~0.44mm wipe movement afterwards -> 0.8mm wipe movement


Retraction speed set to 15mm/s:

Code: Select all

G1 X129.804 Y117.262 E1.0103
G1 X129.004 Y117.262 E-0.6667 F1080
G1 E-0.1333 F900
Some of the retraction takes place while doing the wipe movement (0.8mm) BUT there's more material retracted in a
seperate move after wipe distance has been reached.

This can be seen in the preview - there's two retractions within a short distance (wipe distance):

retraction speed 40mm/s:

retraction speed 15mm/s
