Thanks for your help! This looks kind of the same as what I reported anyway 
Example here: https://drive.google.com/drive/folders/0B7W5lGX-kgL_U0lhMmRacFFiUlE?usp=sharing - squid.svg takes 40 sec to load, and another 40 to do gcode even for a simple laser cut… Then I also have to do segment=0.5mm or it makes the laser slow down at points in the cut. squid_flat.svg (same file, with beziers flattened - it’s 3x the size) loads and generates gcode in less than a second, and laser cuts perfectly
I can obviously do that bezier flattening in inkscape each time, but it just feels like something that might be fixable if there were some way to make the SVG import less detailed?
@Gordon_Williams your files are not that simple. They are composed by clipping mask, so visually you see just one outline burning reality there are many on top of each other, LW does not like that. You get this kind of files when using auto tracing ussualy
Mind that the flat file was loaded and generated the code almost instantly
Interesting - yes, my files came from tracing. Does the flat file still have the clip masks?
Yes it does, but I assume there was a process there, not sure what. What software so you use AI or Inkscape?
@Chuck_Comito your shamrock file takes about 10s to load and 30 to generate. I still think 30 is to much but I need to get home to check it with illustrator. I’m particularly interested insolving the issue you had of being slow at cutting, what file did that?
I use inkscape - I just chose ‘Flatten Beziers’ and gave it a tolerance. I guess clip masks may not be helping matters, but even so the fact that the bezier version is 40 times slower is a bit odd.
If it helps, the non-flat file I gave really bogs down the laser cutter as well. It’ll cut fine, but at points on the curve it really slows down (I guess too many points). Setting the ‘segment’ option fixes it though.
@Ariel_Yahni_UniKpty , that file in the video was the shamrock. Perhaps there is a related issue with @Gordon_Williams issue and it might be (hopefully) workflow related.
I just want to try and replicate. I did not find the same composition in your file, it was cleaner but never the less there’s something there.
@Ariel_Yahni_UniKpty , I’m not sure I understand what you’re saying in your last post.
@Chuck_Comito I meant to say your file was good but still took some time. If i could have the actual file that resulted in slow motion that be good
Guys try the following ( if you haven’t ) open inkscape and select all and ungroup, the go to extension / modify path and choose a very tiny value for example 0.1 ( this should not change anything on the design but pay attention )
Save as SVG and load in inskcape. @Chuck_Comito you file loads almost instantly and process very fast less than 10s
@Ariel_Yahni_UniKpty thanks for looking into all this stuff! I won’t have time to get down to the lab tonight but tomorrow I’ll post the original ai file and a new video of how lw4 reacts. I’m really hoping it might be a pc issue. I really do love all the smoothie features and just got done rewriting the config file to suit my needs. I’d hate to have to find another solution.
@Ariel_Yahni_UniKpty which setting under ‘modify path’ should I use? Flatten Beziers? If so that’s what I did for the ‘_flat’ file, and it works great. My initial question was really whether there was a way to get that same speedup without having to go through that.
@Gordon_Williams Yes im sorry, i forgot to type that in
Yeah, so Flatten Beziers works great - and also fixes any slowdowns when cutting (without having to set segment=0.5). It just felt as is LaserWeb was internally doing a Flatten Beziers with a super-low tolerance. If that were adjustable somehow I could just raise it?
@Gordon_Williams No it does not, i just one of the limitations when handling arcs. BTW i talked to the Dev who wrote this.
Ok - thanks for your help then, looks like I’ll just add the flattening to my workflow
Mind that if you have or know a way to make this better you can always offer your insight in LaserWeb GitHub to the devs
@Ariel_Yahni_UniKpty I just wanted to mention that a new computer build was the ticket. The stuttering disappeared after the upgrade and I can successfully run all jobs even as large as 700mm x 1360mm without problems.
