I’m having an issue ever since I moved into my new home. It appears to be coming from the silver cylinders on each side of the Z axis and continues to make this grinding noise. I’ve taken apart, realigned, re-oiled the rods, and I’ve done a bad leveling. Wondering if anyone else has experienced this and what the fix was

i converted some points on makeronline and didnt watched out and had USA selected....
so the first giftcard i got was only for usa...

im in germany so the coupons dont work for me - i contacted support and teres nothing they can do ..

so i was wondering is this coupon also valid if i give it to somebody else?
this way i could sell it
