Thank you i will make sure to check all of that
about the extrusion how exactly do i set that is it in marlin or is it from pronterface because it's confusing me a little

I'm sorry but I cannot help further as I do not use marlin or pronterface with my printer, thus I'm not familiar with how they work.

This looks like substantial amounts of overextrusion, I'd try fixing that problem before anything else. Change the steps/mm for the E axis in Marlin, there's extrusion tuning tutorials out there that can help you figure out how to get a good extrusion rate. Hint, you've got your steps/mm in the E axis set too high.

but when i searched regards the steps/mm every guide said cold extrude and measure the filament if it's the same number then the steps are fine and i am extruding exactly what i am giving the machine or is that can change sometimes?

Your X belt needs more tension. Also you move a lot of weight (rods, aluminium plates, X stepper). The X belt does not power the carriage in the centre, you only have 2 bearings while you should use 3. All this adds to the (in)accuracy of the print. Also add a picture from the side please. It might be that the platform is too heavy that you are missing steps.

i will add a side picture once i go to the printer. what do you mean x belt doesn't power the carriage and how can i minimize all those errors for example if i added 3 bearings instead of 2 would it matter?

Using 2 small bearings and attaching the belt closer to one bearing may cause the carriage  to rotate and prevent smooth movement, a third bearing or a longer one prevents that. Please also explain by [edit] of your question in words how the platform moves; e.g. do you have 4 leadscrews raising the platform, how are they powered.

Ok are we talking about the same axis here: the axis with just 1 belt if yes then i dont understand where would i put a third bearing and nothing rotates there
if not then we are talking about the axis with 2 belts? and u are talking like there is just one belt so i think i am misunderstanding you a little

How do the  measured X, Y, and Z dimensions of your printed cube compare with the model? Is the Z shorter than anticipated?

yes Z is shorter by 2mm x and y are the expected sizes
