I figured I’d start up a new thread to detail what I’ve been up to.
After I finished my initial wiring and started on the Easel setup, my Arduino stopped responding. I was able to get to the point after it connects to the com port, and lets you jog the stepper motors. I hadn’t turned on the power supply, so I figured I’d take a small break, reboot everything, and start over. After I did this, and restarted the Easel setup, I couldn’t communicate with my Arduino.
I noticed that when I turned my arduino on, it had a solid green and solid yellow LED. Turning on the power supply lit a blue LED, but nothing else. Tried connecting to it using Universal GCode Sender, and no response. Same with the Arduino software. It still showed up under connected devices whenever I plugged/unplugged it, but there was no communication.
At this point I moved to just the arduino, and disconnected everything, removed it from it’s case, and tried to communicate with it. After a while, i tried reflashing the firmware on the chip using FLIP and the instructions online (which worked smoothly), there was still no communication with the boarrd once it was plugged in. I tried working with a spare MEGA I had lying around, and was able to connect, upload, and run things pretty easily. I was going to try driving the x-carve with the mega, but apparently there is limited support for GRBL on the mega, and after two days of troubleshooting I figured I’d just stop by radio shack and get a new UNO.
That was yesterday. Got a new Arduino, uploaded the GRBL version as shown elsewhere on the site (Grbl 0.9j) and was able to power up and connect to the xcarve. I power on the psu, I get a blue light on the gshield. I plug in the arduino, i get a blinky yellow and solid green on the arduino, and the three axis LEDs on the gshield light up.
Now, when I jog the motors, the green axis lights flicker. I don’t know if that’s supposed to be normal, but after hitting any of the directional arrows a couple times, the lights go out completely for that axis (maybe a 3/4 rotation of the gear). If I keep pushing, it still moves and the lights eventually come back on. Spindle control does not work, and when I try to home everything to test my limit switches, it appears to hang.
I’ve just tried using UGS to start a homing sequence, and it throws:
ALARM: Homing fail
I guess since the alarm is tripped, it locks everything up so Ihave to issue a $X to unlock it. I’m kind of at a loss at this point. I’m really over my head and don’t know where else to start trouble shooting. The steppers do move, and in the correct directions and distances, but I figured the lights should stay on. I’ve tried turning the POTs, and it doesn’t seem to make much of a difference. My wiring seems to be sound, as the steppers and spindle work (manual control of the spindle is fine, it’s the automatic control that doesn’t work), and the fan starts up.
Any help would be appreciated!
