The Shapeoko XXL is designed to be affordable enough for any shop and powerful enough to do real work. This is the Shapeoko XXL, nearly FOUR times the cutting area of the Shapeoko v3! That’s a lot of cutting area! The Shapeoko is a 3-axis CNC Machine kit that allows you to create your 2D and 3D designs out of non-ferrous metals, hardwoods, and plastics. Please note, these machines are built to order & have an estimated lead time of 10 days before shipping South Georgia and the South Sandwich Islands.Note that worn carbon brushes or a loose connector on a trim router may cause arcing which results in EMI.This product has shipping restrictions, so it might have limited shipping options or cannot be shipped to the following countries: if your spindle (trim router) power cable doesn’t have a toroid, try adding one (note that what seems to be a toroid on most trim routers is actually an anti-theft device on all the ones I’ve seen).Make sure that the cable isn’t being jostled or disturbed. if you have the option to switch from USB3 to USB2 - if using a laptop try a good-quality powered USB hub - some laptops undervolt the USB ports to save power. if you’re using a USB extension cable or unpowered USB hub, please directly connect the machine using a shorter than 6 foot USB cable - if your cable doesn’t have a toroid (metal cylinder often molded into the end of the cable) and you have a cable which has that feature, try it, if not consider adding one or getting a cable which has that feature.if you’re using a laptop, ensure that it is plugged in, preferably to a grounded outlet using a 3 prong plug if possible.arrange the AC cable for the spindle (trim router) so that it doesn’t cross or be near any of the other cables.This can be corrected with grounding but can be frustrating for new CNC owners if you aren’t aware of this issue. When using a dust boot there are instances where the static electricity can cause the program to disconnect from the machine. The average user won’t even notice this issue. Those cost savings are filtered down to the consumer. To allow for cost efficiencies they allow for a certain margin of error in the manufacturing process. Why such an expensive machine out of square? Well it comes down to tolerances that Carbide3d allows for when machining the components of the Shapeoko. I have had my machine for two years and my X axis is off about 1/8th of an inch and my Shapeoko CNC works great, no issues. The positive takeaway is that it won’t make a huge impact on your projects so don’t worry too much about it. See a few links below to a few ways to fix these issues. While there are techniques to remedy this issue, they aren’t simple, and can be frustrating to dial in. Then started the CNC machine on the left and moved it to the right it would be higher on the line on one side. Basically, the X gantry is not parallel when moved all the way forward to the Y axis rails.įor example if you laid a straight edge from left to right on the wasteboard and drew a line. What this can be attributed to is the X axis gantry doesn’t quite sit flush on the left or right side. As you progress and learn you realize something isn’t quite right. To the beginner you may not realize it but the machine is not square. The machine will require maintenance and inspection and this is just one of the areas to keep up on. (Stat made up on the spot, but frames the thought well). It reduces the amount of times you have to tighten and adjust by at least 85%.
It is good practice to check these periodically.Ī sure way to make your life much easier is to use loctite on these eccentric nuts during installation. This is an inspection and maintenance point of the Shapeoko XXL. The thing to understand is the mentality that these are a set and forget item just isn’t a reality.
Vibration and use causes these eccentric nuts to loosen which in turn allows the V wheels to move up or down.
Why do V wheels and eccentric nuts become loose? This can leave inconsistent lines, uneven material being removed, and in general poor quality end results. What happens is the V wheels get loose and as the machine cuts material it moves left or right, up or down an extra amount because of the loose wheels. What I have found is that when the quality of the cuts start to degrade and become an issue, it’s almost always because of a loose V wheel or eccentric nut. So if I had to say one thing that is a constant area to watch, it’s the V wheels and eccentric nuts. They are held onto the rails by adjusting eccentric nuts which tighten them against the rails. The V Wheels are the wheels which ride along the X, Y, and Z rails.
