It doesn’t look that complex to me. But I haven’t done anything that large. Can you scan or take a photo of it and bring it into Illustrator? Then you could trace around it for the cutpath and export the SVG.
Has anyone checked to see if this computed total time is indeed proportional to the time the GFUI reports? If so, knowing that proportionality constant would be useful for those doing engrave-only jobs to assess whether the job will choke or not.
The file downloaded to the ~100 MB buffer in the GF is just waveforms sampled at 10kHz. So the size limit is just on total job time.
When engraving the time is the time to scan the area at the specified LPI and speed plus the time to accelerate and decelerate at the ends of the sweep. For a large / slow engrave they will be relatively small.
Calculating the turnaround time is probably a bit involved because you need to know the acceleration. Looks like they don’t use constant acceleration, so you need to know jerk as well. I.e. looks like S shaped velocity profile rather than trapezoidal.
Yes, the higher derivatives of velocity will make a difference in total time, but I’m thinking your formula would give a starting point for selecting a workable LPI for a given area and speed, if the proportionality constant is known.
Yes, I understand that. I am assuming the proportionality constant would account for a “generic” additional time due to accel/decel. Yes, I know it depends on many factors. Unless the additional time for accel/decel is insignificant, it would improve forecasting total run times.
An additive correction factor, based on area, speed, and LPI might be a better correction than a multiplicative scale factor.
Can I? Yes. Should I have to? No. I know this is a known issue, but it’s killing the magic.
I’m capable of doing that, but are all of the parents who bought the GF because of the promise of automagically throwing your kids artwork in and engraving it on something else capable of that?
Not an option. Commissioned work with specific size requirements.
I think I’m grumpy.
Edit: obviously I am, because I forgot to mention that lowering to 270 LPI was enough to get it to work with no apparent quality issues. You’d think the GFUI would be smart enough to warn me that my LPI setting was too high, or recognize that I’ve chosen PG veneer, which doesn’t seem to benefit a whole lot from a much higher LPI setting.
