Raster strange engraving paths

[nextime]

Hello, i'm trying to rasterize some images, and then engraving them, but i get unexpected results.

On the 3d view it seems ok, but when i engrave it, there are some paths added.

Any idea on why does that? i'm not sure if it's a bug or something i'm doing wrong...

Which firmware are you using? Looks like the grbl bug. If its marlin, print from SD On 23 Feb 2016 13:45, "Franco (nextime) Lanza" notifications@github.com wrote:

It's marlin, i don't have any sd attached :|

So, do you think it can be something related to how laserweb send gcode?

Maybe i can try to send it by using pronterface...

Confirmed, using pronterface to send gcode it works like a charm, so, it seems to be an issue with the serial implementation in laserweb/node.js?

Marlin cant keep its serial buffer full.. Upgrade to a smoothie or add an SD Card On 23 Feb 2016 14:07, "Franco (nextime) Lanza" notifications@github.com wrote:

I don't think it's a marlin issue as using another host ( pronterface ) the issue disappear, seems more between node.js and serial

Thats why i say, look at the other open issues here... Instead of opening a duplicate to argue (; On 23 Feb 2016 16:35, "Franco (nextime) Lanza" notifications@github.com wrote:

Yet, you rather user your effort to complain than to contribute (;

sorry if it seems to be a complain, it isn't really, probably a language barrier ( i'm not native english ), but i was just trying to understand and investigate to eventually, if i will be able to, even contribute with patches.

Thanks anyway for your pointers
