Board: _Cohesion3D Laserboard/GLCD
Problem/ Question: I have a few questions that I have been searching for. Sorry if these are obvious to others. I have had my K40 up and running with C3D for about a week:
Does the C3D board use USB 2.0 or 3.0 and is there any advantage to USB 3.0 for engraving? My computer currently only has 2.0.
Is there any advantage from a speed perspective or less engraving issues of saving the GCode to the SD card and running it off the GLCD?
Is the new Smoothieware raster fix truly an improvement to GCode processing speed from 1
ms to .25ms? I am engraving at .05mm so I am thinking maximum speed at this resolution is 200mm/sec. Is this a true statement? Following this rationale:
At 100mm/sec and 1 ms update(Old Smoothie), max res. = (100mm/sec) x .001 sec. = .1mm
At 200mm/sec and .25ms update(New Smoothieware) max res. = (200mm/sec) x .00025sec = .05mm
Is .05mm resolution overkill for engraving? Can you really see a difference between .05 and .1mm?
When I create a grayscale pattern in lightburn, the laser engraves 1 box at a time. Is there a way to combine these images and have them engrave all the way across the row for each line?
Does anyone have recommendations for a true grayscale image that I can test for Raster engraving. The test matrix uses fill mode but it is not really representative of raster engraving. I would like to load and test and continuous gradient from left to right across my work area?
Sorry for so many questions but these are the list of issues I have tried researching to no avail.
