scaling and bed seize trubel
-
i am having a lots of problems with prints coming out in the wrong shape and the bed axis limits seems wrong but i can move the head all over the bed now butt stil the prints are miss shaped. are there any obvious mistakes

Can you show some photo examples of what you mean? It's not clear what problem you're having.

@Phaedrux
the prints i tried to make we're meant to be circular, instead they came out oval. so i tried scaling the axis but later i figured out the Y axis didn't fully cover the bed. the Y axis was scaled properly but the same as the X axis but it could only do it well if i said the bed was 3~ times as long.I don't know whether this is a software of hardware problem, 'cos we've already replaced the motors, and now we're trying to remove the mistakes from the config.g

Do you have motor pulleys with the same number of teeth on the X and Y axis? Check, and if not, adjust M92.
Or are either of them loose? A loose pulley will also cause oval prints.
If you command each axis to move 100mm, does it actually move 100mm?Ian

thank you @droftarts , the Y axis indeed had the wrong amount of teeth
