Hey all new guy here, haven't had a lot of experience with any type of cnc. I purchased a small 2x2 table from Precision Plasma a few months back, came with the stepper motors and a Gecko G540 all I had to do was put it together. I finally have that all done(work 1 full time job and 1 PT job) and everything is running. This is something for myself and wife to do at home together. I use inkscape to do the drawings, sheetcam to run the post processing and of course Mach3 to run the machine. I have the license for both Sheetcam and Mach3. After lots of trial and error, lots of reading we finally were able to cut out the roadrunner test. After that we were able to cut out a few basic shapes, stars, circles.... after a few days I was able to get back into the shop to try out a few drawing we made and a few that I purchased. Now here where the problem starts. I cannot get it to cut anything the way it should, stars are off, circles are not circles and some of the other things I tried that worked before either are off the cuts as in it cuts one part and instead of cutting the outer part it cuts through the middle or it won't finish the cuts so the object is not cut all the way, even the roadrunner won't cut right anymore. I'm at a loss as to what happened from the last time I used it to now. Guys please I need some help....
