Hi all -
I’m doing some experiments with Cermark substitutes according to suggestions on other threads here. This involves full power, 100 speed prints for getting solid dark grey marks on brass. After my first experiments, I just started a larger print with a lot of white space in it, and was dismayed to find the length of time scheduled. When it started printing, I could see why - it is travelling at the same minimum speed whether the laser is on or off. Why is this? Is there some setting I’m missing? Normally the head travel when the laser is off is quite rapid.
Source is a jpg, but it is pure white and pure black, no greyscale. As such, I’ve told it to do greyscale at minimum 90 power.
Given that the design is about 80% white space, I’m assuming I could save at least 70% of the nearly four hours this is going to take if it were to build its gcode to properly skip over whitespace. Any way around this?
