If you're not printing in ABS then this would be the quickest timeline: - Buy replacment sainsmart ramps from amazon prime and have it shipped to you. Unless you're running ABS the stock ramps will work fine. This will get you back up and running by thursday. - Ship me your stock ramps board - Order replacements from mouser and have them shipped to me I would hopefully get the parts I need by this weekend and can solder it in and ship it out to you, putting the arrival time about next wednesday-thursday. You could then feasibly return the amazon one, use the one I shipped you, until robo3d sends you a replacement. Then you'd have a spare.
