Before you go wasting more money on controllers similar to what you already have. Tell us more about your machine. Straight lines could be down to that and not the electronics. You could probably do with some settings changing if your loosing steps etc. pics are good

Sorry, I was bein' a sarcy clever dick re the straight line reference I've attached another pic as to what it does. I thought if it can't engrave something, surely it should be able to cut out a 52mm diam hole a 39mm diam hole and a rectangle around the pair so I could make a vacuum hose mount - boy was that a total failure. My son-in-law's da used to work in the tool industry and knows his way around g-code so I showed him the g-code to make sure I didn't have any errors and to the best of his knowledge it should do just what it's written for which is making me lean toward the controller not doing what it's bloody well told which is probably Karma comin back for me for bein' the same as a kid

The blue line in the image is where the rectangle is SUPPOSED to be, as for the holes well they're just plain outta shape. Oh and that was a scrap piece of MDF so try and ignore all the other lines at the bottom of the image and the upside down letter in the top right etc and you will see what happened to the rectangle
