DIY CNC Router Uses Chains The Right Way _HOT_

Notice the gantry overhangs? The gantry beam is mounted in front of and extends past the side support plates. This allows the router carriage to slide past the side supports (more on the right than on the left btw). You don't see this much on DIY routers for some reason. This setup allows the router to cut from edge to edge a full 30" in the X axis.

DIY CNC Router Uses Chains The Right Way

The router carriage is glued up from two layers of 1/2" cabinet grade plywood, much the same way as the gantry side plates. Since I have that overhanging gantry, I was able to make the router carriage longer (spreading the v-bearings further apart) which increases rigidity in the X axis. The Makita router is mounted on the left side of the carriage. This opened up area for the dust collection system to the right of the router. The carriage has four of the v-bearings that run on the top and bottom angles on the gantry. Tensioning is done the same way as on the gantry side plates.

Take the cable from the X-axis and Z-axis NEMA 23 stepper motors as well as the router cable and insert it into the Y-axis drag chain. Clip the tabs in to secure the wires. Ensure the drag chain is facing the right direction (with the hole-type link, pictured) to fit into the correct end links.

The GX2525 Comet is high performance, general purpose machine tool positioner, suitable for many uses such as guitar building, clock making, plaques, signs, RC aircraft parts and more! New GX series models include a high-rigidity HD gantry with taller uprights for increased clearance.

Depending on what kinds of IoT devices you have, you can use them in conjunction with other pieces of technology for even greater benefit. For instance, the information collected by a sensor in one of your warehouses could provide valuable data that helps you automate other processes, such as forecasting and asset tracking. This high level of integration is essential as supply chains become increasingly digital.

Chain drive is a type of mechanical power transmission system that uses chains to transfer power from one place to another. A conventional chain drive consists of two or more sprockets and the chain itself. The holes in the chain links fit over the sprocket teeth.

Conveyor chain drives find use in industries such as packaging, automotive, food and beverage production, pharmaceuticals and textiles. Attachments can be fitted to conveyor chains to adapt them for various uses.

Three roller chains with different shapes of side plates. Left to right: The parameter for minimum link plate-width-to-roller-diameter ratio (Wl) is set as 0.92, 0.6, and 0.25, respectively; to build roller chains with straight or curved shapes. For all of the cases, the optional parameter Db is set to zero for no bushings between links.

Each router has its own view of the topology even though all the routers build a shortest path tree which uses the same link-state database. These sections indicate what is involved in the creation of a shortest path tree.

By default, a router uses a Null authentication which means that routing exchanges over a network are not authenticated. Two other authentication methods exist: Simple password authentication and Message Digest authentication (MD-5).

This can occur if, for example, a company tries to merge two separate OSPF networks into one network with a common area 0. In other instances, virtual-links are added for redundancy in case some router failure causes the backbone to be split into two.

Redistribute routes into OSPF from other routing protocols or from static causes these routes to become OSPF external routes. To redistribute routes into OSPF, use this command in router configuration mode:

Yes, you can use a laptop as long as you have a free USB port. Our CNC router uses GRBL firmware on the microcontroller. The microcontroller uses a USB to connect to the computer. Open source software such as UGS - Universal G-code Sender can be used with GRBL to operate the machine. Both GRBL and UGS have good documentation on the internet. The assembly manual can be downloaded and reviewed here.

The Evolution 4 CNC router is like most CNC machines as it uses g-code files. The g-code files are text files that can be computer generated or written by hand. There are several open sourced software packages that generate g-code.

The Evolution 4 is a CNC router that uses an Arduino microprocessor to interpret the g-code file. The firmware is called grbl ( is pre-installed on the microprocessor and uses a USB port to receive serial port information (G-code) from software on the computer. I recommend UGS, Universal G-code Sender, software to send the g-code text file to the controller.

Lastly, I wanted the router to overhang the end of my spoilboard a bit so that I can (hopefully) cut dovetails in upright stock, so I slid both spoilboards back a couple of inches, which reduces the Y range a little more.

Note: This is an older (2+ years old) project, and there are now better third party options available (check Millright groups on facebook), even completely replacing both the Z plate and router mount with significantly beefier aluminum parts free of these issues.
