print a smooth flexy print with pictures

hi, I have two v2 flexystruder printers and I have been running into a problem with one of them printing not as smoothly as the other they both are printing the parts with the same cura settings except for the separate e steps each printer has. note: it still could be an e step problem because I was only going off of memory from 6 months ago when setting up the printer settings in cura. but I am concern that it is some thing wrong with the printers or head.
