I just got my JGRO up and running for the first time this weekend. While assembling it I managed to break one of my DumpsterCNC AB-nuts so I am not able to run the z-axis, but have both x and y running. I made a pen mount for it so that i could at least seem some fruits of my labor and draw pictures of what i would be routing. very cool. However, there is something wrong with the scale of my machine. When drawing the EMC splash screen g-code "EMC2 Axis" it only draws it about 1/4" tall, i think it is supposed to be larger than that. I also tried making some drawings in Inkscape and converted them with gcodetools and they worked, however they are much smaller than they are supposed to be as well. I don't really know where to start trouble shooting this as this is my first machine and first attempt at using cam and controller software. Any thoughts? Thanks
