cutting rhombus not a square

[hardshoe]

Hello Marco , long time no see . I was wondering if you would have any pointers on a wee problem that I've just found. My machine after working with no problem for quite a while now cuts a rhombus rather than a square , most don't notice but I do . It runs off 2mm over 100mm ( the lines on x axes and y axes are parrallel to each other) on the y axes which I know isn't a lot but if your making parts it counts.
Thanks for your time

Problem solved , for reasons best known to the software the x y speeds had changed , reset both to the same setting and it's sorted.

Follow up to this post , checked the xy stages and found the x gantry ran out 2mm over 200mm , bit of work but totally square now.
