Hello everyone,
I have been printer less for about 6 months now. I paid for a warranty on my FlashForge though AIG and finally got my printer back. Soon as I got it unpacked I noticed the rails looked crooked. I haven’t seen this printer in so long I dont know if that is what they looked like originally. I have attached a photo. Please tell me what you guys think before I turn this ting back on and mess it up more.

Hi @Sean_Soso well, it’s certainly crooked and whoever did that shouldn’t be charging you any money!
Not sure how it’s crooked though - the left-hand side of the carriage (from your photo perspective) is passive - there’s no thread or belt - so the “crook” must be entirely in the carriage on the right-hand-side. I’d send it back or perhaps even demand a new one, given that you don’t know what else has been affected.
Why did you send it off in the first place?

Definitely do not turn it on. This will have to be straightened and it is scary!!
I have a video I think and if I can find it I will post it, probably tonight. What you need to look for is the little “gears”/“pulley’s” that are at the front and back on each side for the Y axis belts and see if they have set screws. If they look like white plastic with no set screws then the way to fix this is to grip both sides of the gantry and carefully move one side in a direction to bring it in line with the other. the scary part is you have to make the belt jump teeth.
Try googling for align flashforge gantry or search youtube.

It has belts on both sides. This is a pretty common problem. They are surprisingly easy to knock out of align.

Whoops, so it does - not sure how or why I thought it didn’t. Need more coffee.
In that case, presumably it’s not too hard a job to realign…
It is a grab both sides and make it jump teeth. What I did was to put a piece of easy to see tape on the bed that was parallel with the front edge of the bed as a guide. Then I would straighten until the lateral rods were parallel to the tape.
That is assuming the front edge of the bed is parallel to the machine.
I thought the x axis stepper motor was broken due to the printer shaking violently, they replaced the motor and motherboard.
Well Friends I was able get the gantry realigned no problem. I fired it up started the script to level the bed and wouldn’t you know it the z axis sensor clicks but does not stop the bed from trying to go up.
Check for loose cables and connections. If nothing there then change out the cable and if nothing then the limit switch. Maybe the switch first!
What script? Did you do a “home” from the printers display? See what that does. Also use the bed level from the printer display.
So 1st I just reseeded the cable on the sensor and on the motherboard, didn’t work. Pulled up a schematic of how it should wired…The z axes cable was plugged into the wrong spot. Moved to correct spot, tested, still failed. Looked closer at the sensor and realized even tho the cable was seeded the pens were bent out of place. Bent the pins, tested, and worked.
Thanks for all the awesome help guys.
Running a small print right now

What did you do to realign it? I’ve got the exact same alignment problem.
Manhandled it lol just held one side and pulled the other making it jump a few teeth on the belt. Hope that helps.
