hi guys, recently setup my A3 pro, had a little difficulty setting up the software, some of these problems sound similiar to issues i had...
- selecting serial\com port - when i followed the instructions, it kept saying to hit the refresh button after selecting the correct com port, COM6. when i hit refresh i would keep getting "unhandled exception error"
solution: select the correct comport COMx, BUT do not hit refresh, i usually go into settings and select machine, you should get the "switch to elekslaser mode successful". setup the rest of the work piece and you should be good to go. I usually click the weak light on and do a preview to gauge my "acreage"
2- loading custom pics - make sure you edit your pictures down before loading into elekscam. try to reduce the size as much as possible. i tried loading a picture but when generating, program would crash with an "out of memory" error, basically shut all programs down in task manager. i then realised the file i was loading was 66Mb, i loaded a different and smaller file 58Kb. no problems
i ended up doing two tests of this piece,
a realpoint 6 lines\mm; laser 800; 18mm pine ply (1hr :31min TBC) about 300mm
an outline laser 800; ply (30 Min TBC)
needless to say a lot of fine tuning and testing still to do, hope this info helps ..
