1- my 50w machine came with 2.14.9 on a stick, but didn't use it because my other 3 machines were using 2.14.10 . My 'ebay2' machine was setup with 6 different EzCad's loaded into different folders, each corresponds to the lenses I have; a 70mm, 100mm, 150mm, 200mm, 250mm and 300mm; each program has it's own specific settings for each lens. When I got the 50 watter I just copied those 6 folders onto my old Vista laptop and everything worked great, still does! I've made a few minor tweaks here and there is all...
2- I have no idea where to even find that 'agree/disagree' dialog box. Searching the entire 2.14.9 disk for 'license' brings up simple notepad text files, one in English, one Chinese. Looks to be the same text, just no radio buttons below. Could be that dialog came up during initial installation of the dog driver-? If so I forgot!
HOWEVER, IF that's the reason the dialog box DOES come up, then it seems logical your machine's trying to re-load the driver. AND, I can only surmise that if the machine won't fire and it's asking to agree to load the driver, and nothing happens when you do, then it's highly likely your control board is fubar, since that's where the driver resides.
3- Go to your control panel / device manager, and near the top of the list your
BJJCZ Device should show up. Expand the folder and open the
laser mark control board V2 file and see if 'device is working properly' appears. If NOT, then your computer is aware of the problem... If it says it IS working properly, click the Driver tab and click Update Driver and let it look automatically. It may or may not say 'the best driver is already installed'. Regardless, click the Browse computer for computer software, then click Let Me Pick from a list of drivers.... the BJJCZ driver should come up, just click on that it should re-install it--
------IF ANY/ALL OF THIS doesn't work, then I would thing this too is indicative of a bad board...
4- just for fun, I just found a long USB cable, and connected it THIS computer I'm using, which is my "main" computer and has never run any of my fiber lasers. I also plugged in the 2.14.9 stick. I connected to the 50w machine in the other room and fired it up. When I did this computer 'couldn't find the software', so I pointed it to my stick, and it automatically loaded the driver. I ran EzCad off the stick, it loaded up fine. I grabbed a saved job off the laptop thru my network and saved it to this computer, and opened it in EzCad. It red-lighted and engraved like it's supposed to. The 50 is my newest fiber and it's 2 years old, and that was the last time I've fiddled with installing EzCad until now, and everything worked out fine! And FWIW ALL 4 of my fibers have MAX lasers. OH, and I still didn't get that agree/dialog box....
IF you go into the Device Manager, and delete the fiber's driver and it doesn't reload right, or doesn't work if it DOES reload right, I'm still thinking controller...
ONE more thing to try: In the EzCad folder is a file called CorFile2.exe-- OPEN THAT, and first thing is to click the Set Laser Parameter bar-- at the top, switch "laser" to "IPG", as "C02" is probably defaulted. NEXT, at the bottom of the screen is Power Analog and Frequency Analog outputs, change those to 50%... Now, get some material the laser can mark, that's at least as big as your laser's engraving limits and focus it. THEN, click the Mark 9 Points Rectangle-- What's going to happen is the laser is going to go thru some full-range motions WITH the laser firing. On MY machine, after it got done it then drew a tiny continuous rectangle that slowly grew larger but NEVER stopped engraving! So BEWARE of that!
--I have no idea what the CorFile even does or why, I just it's some sort of correction file and I've never learned what it's for. HOWEVER, my Triumph originally came with a USB dongle, and I found out that running this little program THE LASER FIRED DURING THIS PROCESS EVEN WITH THE DONGLE REMOVED!! Not sure, but THIS may be a way to find out if your laser is bad or not. The caveat is that the dongles are part of the controllers these days, and I'm not sure this will work, but if it DOES fire, then YAY!
Hope some of this helps!
