I would try some light oil or WD-40 on the screw, also if your bit is dull it will cause the machine to hang on some of the cuts and that might cause the erratic motion.
If the machine runs smoothly when jogging it along the X axis when thee is no load on the lead screw from actually carving wood, then the bit might be suspect.
By the way , yes your machine looks squeaky clean in that area, mine not so much. It will soon be time for a "white glove cleaning" of mine after I finish getting ready for a craft show this Memorial Day weekend.

ok perfect, i'll put some oil on it! but my last 2 carvings was with a brand new 1/50 bit... low no jerking or anything, med it will not only jerk but it actually will kinda stop 2 times for a split second and keep going... maybe with oil it will be fine. have a great time at the show..

As the machine is traveling along the X axis carving a project the machine will slow to a degree while the Z axis does it's thing going up and down. The more complex the design is the slower it will go. You might listen to the spindle motor as it runs thru a project to see if the rpm slows way down when doing a cut, if that is happening it could be causing the the X axis to hang up. The last motor I had that went bad the RPM would come to almost a complete stop during a carve.

Sounds similar to when I had a bad spindle motor also, mine would actually come to a complete stop (bit would stop turning, x axis movement would bind and machine would error code. Changed out the spindle motor and I've had no problems since.

i called Steve over @ iconic cnc and he was saying what i'm going through should be ok as long as the project is not getting affected! then he told me about their new 2015 i think it is, man sounds like a nice machine that they worked out all the bugs out of... works like a regular cnc machine for 3900. after a 1k off for the promo code. anyone have it and how do you like it ? if the 1013 does a carving in 5hrs this one does it in 45 min. realy thinking on it!! still love the 1013 too. just having fun!!

I do know that the new Iconic machine has a much beefier spindle motor than the 1013, it is 2-3 times the size of our spindle motors. Plus all of the axis X, Y and Z are driven by lead screw which allows for more rapid movement. It appears that they went thru the host of problems that have occurred over the life of the 1013 and made improvements based on that information.

what is the best bit and scan step for carving out outlined cars you think ? i've been useing the 1/32 with 0.007874 and sometimes nice and others not so good ?? when i talked to steve that machine sounds awsome!! thanks

Depends on how you do the outline I guess, if you are taking away everything but the car with limited details in the car body itself, the 1/32 should do well. If you are carving a car with a lot of detail in it, then the 1/50 makes more sense. I use .0059 as my scan step on every project, but it is because my particular machine doesn't cut smooth flat surfaces at the default setting. While I realize it takes longer to do a cut, I save a lot of time (and my sanity) by not having to sand so much at the end.

Personally I would go with the Iconic if I were able to get a new machine. A big drawback for me with the Shark would be the fact that it utilizes a router for a spindle motor. It is my opinion that routers were not designed to be running for long periods of time. The inner workings of most routers use plastic housings to hold bearings and the rest of the motor together, so I don't see how one would get the close tolerances like those you would get with a regular CNC spindle. Most if not all spindle motors are made from metal components and housings,... not plastic and I am sure there is good reasoning behind that.

i hear yea... i'm leaning toward the iconic. i need to find out how big the project table is though, the shark comes with a 25X36 witch is nice, but its also 5900. and has a lasor also but use's vcarve and i understand that its alittle more work than ipicture. the guy suggested for me to get the trial vcarve for my big cnc and try it... i guess vcarve converts gcode too. anyways the iconic sounds good!

my first real machine problem... i was getting ready for a carve and had it all set up and the y hit the safety to the minus side because i had it set to 19" ! so turned it off and corrected the goof up and made it 17.5 re-did the #s on FD and turned machine on and all it will do is very slowly move the y all the way to the plus side and do nothing ? no error or anything. did the keyboard just go ? i've done approx 15 projects w/o a problem.. thanks

When you setting up the carve by jogging the X, Y and Z to the start point does the machine move ok then?
