Quick question guys
When You done Ramps conversion guys,did you move yaxis end stop to bottom from top?
No, you do not move the endstop when doing the conversion.
Check here for what you need to do to get it right : https://github.com/openhardwarecoza/LaserWeb/issues/103
EDIT : Just checked, you ar ethe one who posted the answer lol
You can add more endstop if you want, two endstop for each axis is probably a good idea, not sure though.
I moved endstop to bottom left,genuine arduino in machine and laserweb still not working :(.
Prontafece work fine with gcode from inkscape.
Laserweb give msg x endstop and y endstop hit msg when i try do anythig 
After week still no progress i dont have any more ideas
Buffer is fine now,when i use machine in prontaface there is no delay and stops in printing
About laserweb i mean ,it show me server ok,machine connected but no control ober it.when i try reference nothing happen,just said command send from console.when i try cut it give me series msgs about hitting endstops
Just notice one thing now,so its definitly software problem
When i put G28 thru console before i do anything machine reference and i have control over.if i will try use reference widget , nothing happen
Yes i do(i hope ,its from his oficiall github)
I found it problem.
First one was display,it tooks to many resources,second one was me i thing because i was pressing zero machine g92 ,but i should press house icon
