Hello, I have used 3d printers for a while now and have come across a problem that I believe is one of the x or y motors being stalled or slower than the rest, usually from my experience I have found that a print always form corners that are 90 degrees, but on my new Flashforge Finder I have found that it prints at corner angles of 85 degrees and in the adjacent corner, 95 degrees, although it is a very small problem it is very noticeable in large prints. I have properly leveled the bed so that the vertical angle from the bed is always a perfect 90 degrees. Please give your opinion, Thank you.

It sounds like your xy gantry/effector/other name for it, is out of square. The dreamer has two smooth rods left to right across the x axis? If one side has skipped the belt or has an issue on the pulley this would cause your symptoms. Try pushing the carriage all the way to the front or back and see if both sides are equal distance from the front/back of the machine.
I see why that would be a problem, I checked and saw that the pulley is fine and functioning properly, I also thought that maybe from being a printrbot owner I recall having to go through the horror of calculating steps/mm for my printer, now maybe the printer has its steps/mm ratio off. What would you recommend for adjusting the motors? I still have not determined which motor or if both are causing the slant. Or if there is another way to avoid messing with the steps/mm, feel free to recommend an option.

Those motors should be one per axis. If you are printing odd angles as you describe it’s more likely the carriage is offset. Steps per mm would only fix the distance traveled and thus would not fix your issue of the two ends traveling different amounts.

Ok thank you, so what exactly do you think I should do?

No clue. My first thought was: “Try pushing the carriage all the way to the front or back and see if both sides are equal distance from the front/back of the machine.”
This would rule out the possibility of that specific problem.
ok, well thank you for your input on the idea
