New board- can't connect... Solid green light only

New board- can't connect... Solid green light only
I just powered up my board for the first time. I turn it on and I have a green solid light. There is no orange blinking light at all. I am able to see the JJROBOTS_CB SSID, but when I connect to it, the wizard does not work (looks like it's trying to resolve 192.168.4.1).

Any suggestions? I can't seem to do anything at this point.

Looks like it has the wrong firmware on it after doing some research. I'm currently working on getting the latest firmware and the older version of Arduino, hopefully it will resolve the issue.

RE: New board- can't connect... Solid green light only
Got the board working. Now it looks like the eraser servo is off, it is not in the right position. It is all the way to the left. I am not really familiar with adjusting servos - is there any information on how to get it centered? I followed the instructions exactly when installing it, I'm thinking it may have never been calibrated.

Check the end of the assembly guide here: https://www.jjrobots.com/iboardbot-assem...tructions/ (My iBoardbot is now drawing or wiping the glass correctly. What is going on? )
There are photos of the servos set in the right place. If you move the iboardbot, they can get loose and you may need to re-adjust them again

Thanks. The wiper is now resting on the whiteboard, and the lifter servo is slightly angled raising it. However, when I go to print something, the eraser stays on the board, and the marker sometimes makes contact, and sometimes doesn't. Erasing seems to work fine. Every now and then it will make a letter, but sometimes it will get smudged or erased. Most of the time it just "air prints". I checked the marker and it is completely seated, almost touching the whiteboard during standby... Any other suggestions?

The eraser is not moving out of the way all the time. It mostly stays but sometimes it moves, and allows it to print a letter, but for the most part it is staying on the board...

It looks like it may be a servo issue. Sometimes the wiper moves out of the way, other times it just stays in erase mode. I see the board light up every time it's supposed to change the servo position. I may have to try a different servo.

I took the eraser out of the equation (removed the arm) and the writing seems to work, except it creates drag lines, and the lifter arm keeps wanting to hit against the assembly. I also noticed that the servo is making a grinding noise- it seems like it is way off in terms of calibration, even though it is at rest like the picture. The range of motion seems like it's about 90 degrees off where it should be, if it is supposed to have a full 180 without hitting anything.

I started a new thread for my servo issue, since the original issue is solved with the firmware.
