Just a little reminder, you should periodically check all of your printer parts for slop/wiggle. I thought I cleared up the wiggle that I had on my printer, but the rear carriage that slides up and down the tower was capable of twisting and doing other wiggle movements. I just managed to adjust it to remove the wiggle.
Is there any one here who has experience with changing firmware setting on a motherboard?
Yeah. Just list your board and firmware version or at least the printer and when you got it. You will need to say what you are trying to accomplish and clarify if you want to change settigs or firmware versions. Do not ask in this thread though. Ask outside of it where people will be able to see your post.
