Update - I got help on the Glowforge World FB page and it turns out I still had that carriage belt wrong. After fixing that, it works like a charm now. Thank you to everyone for always being so helpful.
Hello GF family,
I am trying to cut a simple cross. I drew one myself and also tried one from the insert menu. It looks fine but it cuts off. I can’t see how to attach a picture but the 4 protruding rectangles that are supposed to form the cross are wacky. Hope this makes sense. Any ideas on my problem?
Your cut line seems very thick so I suggest you check that your lens is inserted properly and that the focus beam is landing on your material. Also, the wavy lines indicate either a broken wheel or a carriage plate belt tension problem. Have you recently removed the belt and replaced?
I did have the belt off that moves the head right and left when cleaning last time and have not used it since then. How do you control the tension on that belt. I remember struggling to get it back together. I did check the lens that is removed with the blue tool and it seem to be seated properly as far I know. (not that I know much … lol)
Turn off your GF. I recommend removing the print head carefully, make sure the carriage slides back and forth smoothly, ensure the ribbon cable is properly inserted, and when you replace the print head, you should feel a strong magnet as it more or less takes it our of your hand and seats properly. When you go to turn the GF back on, remove everything from the bed, so the homing doesn’t have any material to focus on, sometimes that trips it up. Good luck!
You ought to remove the belt, remove the carriage, and make sure the carriage wheels are in good condition. The front wheels have a tendency to break after time. Reinstall the carriage per the GF instruction video, ensure the drive belt is BETWEEN the front and rear set of wheels, and make sure the carriage slides back and forth easily, it should be super smooth from side to side, all the way.
After you believe the carriage is sliding smoothly, you can reinstall the belt. First put the right side on, and making sure it is seating properly on the right hand wheel, then you can work the left side of the belt onto the drive wheel, it’s not easy, but you’ll get it on.
I can’t tell you how much my ‘dorkyness’, and I suspect many others, appreciate your help and patience. I have had my GF for about 2 years and just use it for hobby, fun stuff. Very lucky for me that I have had few problems with my cutter.
THANK YOU! I suspect (hope) to post success shortly.
Other than hardware failure (motherboard, the computer inside the machine) or communication with the laser head and/or camera, the only cause I am aware of that will prevent the head from moving shortly after power-up is no wifi connection. Centering the head is the next thing the machine does after validating the kernel (firmware) is valid, checking a bunch of sensors, and the wifi/internet connections to status.glowforge.com & app.glowforge.com is established.
As you have been messing with the head, checking the connection to it (wide grey ribbon cable that plugs into the large black connector) would be the first step.
I hope when you cleaned the machine, you didn’t use any liquid around any of the connectors. Also, for future reference, there is never any reason to remove that cable, or loosen the bolt for the idler pulley wheel unless you are having to replace the belt.
