Varying the movement speed when the laser is off.

[klucsik]

Dear developer,
Thank you for your great work, I have a chineese laser engraver from ebay and with your plug-in i can do some real great work.
The BW random treshold function can do some real magic with pictures, i love using it!
The engraving is a bit slow process, if i could manipulate not only the speed when the laser is on but the repositioning speed as well, it would be great.
I think it could be tweaked in the GRBL software in the arduino but I don't realy want to reprogram it becouse I don't really understand the software yet.
Can you make a version of this plugin with this feature?
Many thanks, Klucsik KP

Edit:
The GRBL software is adjustable without reinstalling. with the tewak max speed and acceleration i improved the engraving speed.
