Cable Track Installation

Sun, 11 Dec 2011 22:30:25 -0500

CNC Router Parts will soon be offering cable track kits for sale on our site, and we've pre-sold several to customers who have purchased mechanical kits. There are a lot of parts to the system, so we added this section to show how it all goes together. Better pictures coming soon for many of these descriptions, but we wanted to get something up here quickly.

The first step is to attach the large wire trays to the X axis -- the trays help route the cables and support the plastic e-chain guides. The x axis tray mounts using the provided machined rectangular rail clamps with the two slots and tapped hole. The brackets are attached to the underside of the x extrusion using the provided 2.5" 5/16-18 carriage bolt. The tray slides into the slots on the brackets, and is held in place with the provided 3/8-16 hex cap screw and large fender washer -- better pictures coming soon. The tray should be positioned so that it is biased towards the back of the machine, as shown in the photo below

The smaller gantry tray mounts to the gantry by placing the lip of the tray in the lowest t-slot of the gantry. The machined aluminum clamps connect to the t-slot immediately above this with the provided 7/8" x 5/16-18 carriage bolt and hex nut.

Next, connect the interface bracket for the Y cable track and Z cable track to the open tapped hole on the gantry rack and pinion drive, using the provided 3/4" x 5/16-18 hex cap screw and washer. Note, the picture following shows a washer under this bracket, but this is not necessary. The bracket is slotted to allow alignment of the Y cable track with the tray.

You are now ready to run your cable tracks and install your cables. Installation of your cables in the tracks is fairly easy, and is facilitated by use of a screwdriver to open the tops of the tracks:

The next section deals with attaching the actual cable track to the extrusion. The X axis connection is the most involved, so this is detailed out below.

Before you start make sure you have laid the cable track down so that the section with the end piece with the holes in it ends up next to the extrusion and make sure you have the following pieces from the CT- Fast hardware kit: (1) 5" hex cap screw, (5) 5/16 flat washers, and (4) 5/16 jam nuts

At the beginning your set up should resemble this (possibly without the cables -- these can be added after the track is installed):

Working from the outside in towards the extrusion, start by threading the 5" hex cap screw through one of the flat washers and insert the screw in the outside hole of the cable track kit, then add another washer and a jam nut.

Continue by adding an additional jam nut and then a washer.

Thread the hex cap screw through the inner hole of the cable track kit and add the following components in this order: washer, jam nut, jam nut, washer.

You should now have something that looks like the following photo and you are ready to attach the hex cap screw to the extrusion.

Screw the bolt the remaining way in, and the X axis track is connected.

You can now connect the Y axis cable track to the interface bracket using the supplied 5/16-18 hex cap screw, 2 washers, and jam nut. You can also connect the Z axis cable track through the hole in the end bracket using the supplied 1/4-20 screw and jam nut.

Finally, the Z axis cable track should be connected to the Z axis extrusion with the supplied 3.5" carriage bolt. This uses a similar strategy to the X axis connection.

The completed connection should appear as follows.

All that remains is to route your cables through the system. For your X' axis motor opposite the X axis cable track, we recommend running the cable through the cable track on the primary side, and then through the hollow of the gantry. The sections of cables unsupported by energy chain can be fixed to the tray with cable ties, and this is recommended.

Any remaining questions, feel free to contact us and we'll do what we can to get you up and going ASAP. Enjoy!

Alvin's 4' x 4' R&P Machine

Sun, 13 Nov 2011 23:55:35 -0500

Alvin is fortunate enough to live close to a metal recycler that sells extrusion by the pound, so he went all out in designing this tank of a machine. He used our Nema 23 R&P components and extended linear carriages as part of his build, as well as our gantry risers, and constructed his own wooden machine base.

G540 Nema 23 Wiring Instructions

Wed, 05 Oct 2011 00:37:01 -0400

While the G540 makes hooking up motors and getting them working a breeze, it can still be a bit daunting for those new to electronics and CNC. We created this handy step by step guide to help get you going with our products. Read on to see how it's done using our components.

The first step is to insure you have all of the parts needed -- these are shown below. You'll need an AC power cable, a DC power supply, some 18 AWG or larger wire to connect the power supply, a motor, a motor cable, a parallel port cable, and of course a G540. Note, this guide shows a 7.3A power supply for a 3 axis system, but the process is the same for the 4 axis system, you'll just be using the larger 12.5A supply. It's also recommended to have an emergency stop, but if you don't have one, you can jumper this out initially while you're testing motors off of your machine. We'll show you how to hook the system up both jumpered and with an e-stop.

Next you will want to make sure you have a few tools handy -- a Philips head screwdriver for the power supply, a small Philips for the G540 connections, and a set of wire strippers will be needed. For a professional install, ferrules and crimps can be used on your wire ends, but this isn't strictly necessary.

Start by cutting the female end off of an AC power cord. Almost any cord will suffice, as the G540 does not draw excessive amounts of current. Do not plug the cable into the wall.

Strip the ends off of the wires, and crimp on ring or spade terminals if desired.

Next, locate the AC input terminals on the power supply.

Install the wires per the colors below. Green is ground, black is hot (or "line") and white is neutral.

Next up, you'll need to connect DC power to the G540 using your 18 AWG or larger cable. Keep these as short as feasible (less than 12" if possible), as the G540 can be finicky about inductance if they get too long. We suggest red for the 48V+ and black for common (48V-). Crimp on spade and ferrules are shown, but are not required.

Connect these wires to the V+ and V- terminals on the power supply as shown.

Connect the other end of the wires to the power terminals on the G540, pin 11 for 48V+, and pin 12 for common.

Next up, you'll need to either install an emergency stop, or a jumper for the emergency stop if you don't have one. Either way basically shares the same terminal 12 with the black wire for common, and runs over to terminal 10. An emergency stop is recommended, but we'll show both methods. The jumper method:

Or the emergency stop method (again between terminals 10 and 12):

Your setup should now look (roughly) like this:

All that's left is to plug in the motors and a parallel port cable and you're ready to go! If you're using one of our parallel port cables, you'll be in good shape. Make sure any DB25 cable you use is fully populated -- many cheap printer cables do not have all of the pins going through, and is often missing conductors that are assigned to step and direction signals on the G540.

Plug into Mach3 or EMC2 and start CNCing, and revel in your new electronics know-how :)

We hope you found this guide helpful and informative. Now the mandatory disclaimer: Working with electricity can expose you to dangerous or lethal AC currents. While this guide contains helpful information, you are responsible for keeping yourself safe. If you are at all unsure about completing any aspect of your electrical wiring, hire a licensed electrician or qualified electrical contractor to do the work for you.

Gantry Rail Clamp

Fri, 26 Aug 2011 15:44:10 -0400

Our new gantry rail clamps allow easy mounting of 2.5" cold rolled steel rails onto 3060 extrusion used for machine gantries, and are part of our new machine kits. These clamps pay for themselves by allowing the use of narrower steel on taller gantries, rather than more expensive 7" steel.

The clamps reference off of the extrusion t-slots to self-center, and provide an even 2" spacing, ensuring the proper 0.5" overhang for our linear carriages and rack and pinion systems. They also provide additional rigidity in connecting the rails to the extrusion. We recommend using one clamp every 12" or so for maximum connection strength.

Each rail clamp kit includes a clamp, 2 carriage bolts, and 2 hex nuts for easy connection to 3060 series extrusion. CAD and drawings coming soon.

Dust Collection

Sun, 31 Jul 2011 23:27:58 -0400

CNC routers make dust, and a lot of it. This can wreak havoc on even the heartiest machine components if not controlled properly, so installing a form of dust collection at the source is highly recommended. The DIY CNC crowd has created a multitude of clever and very functional solutions. One of the best is the split shoe system from Kent CNC. This system is exceptionally well-designed, and Kent makes versions that are compatible with a multitude of different routers and spindles. The detachable brush ring provides quick and easy access for bit changes, while the 3” length brush clears hold down clamps and other irregularities in work height. Finally, the clear acrylic lets you see what the bit is cutting. Once you get your machine up and running, this is a highly recommended upgrade.

Enclosure for Nema 34 Electronics

Tue, 03 May 2011 09:55:04 -0400

This 20" x 20" x 8" electrical enclosure is an industrial workhorse. It features heavy-gauge metal construction, with cutouts for connections at the bottom, including motor connectors, a parallel port hookup, software controlled relay power plugs, and even a spindle connector. The enclosure also includes a component mounting plate, a fan to keep the system cool, and a lighted power entry module with a power switch on the side. Contact us and we can provide a pre-drilled panel with a suggested component mounting pattern for a nominal fee.

The enclosure itself is large enough to fit a 4 or 4+1 (rotary) axis kit, and also leaves space for a Hitachi VFD to drive an air or water cooled spindle (controllable from a 0-10V analog signal on our breakout board. More pictures and details coming soon!

Price: $199.00

4-Axis DIY Nema 34 Kit

Tue, 03 May 2011 00:55:39 -0400

For industrial users and the hobby builder who appreciates pro-grade equipment, CNC Router Parts is proud to introduce our new Nema 34 DIY kit.

This kit features top-grade components suitable for heavy machines, high-speed rapids, and deep cuts. Individual 7A rated Gecko drives are matched perfectly to our 7A motors, and our cabling solution makes for a polished and rugged connection system. The kit features the following:

3 960 oz-in Nema 34 motors for X and Y axes
1 640 oz-in Nema 34 motor for Z-axis
4 Gecko G201x Motor Drivers
4 7A rated shielded motor cables (two 20' and two 12' cables)
4 bulkhead connectors to mount in your own electrical enclosure
21A 48V power supply
4 Axis multifunction breakout board

Need a box to put it all in? We have high-quality metal Nema enclosures available, with cut-outs for the motor connectors as well as for relay-controlled auxiliary power, a parallel port hookup, and even a spindle connector. Note, this kit does take more wiring than a G540 based solution. We encourage you to give it a shot, and we're happy to offer advice on wiring, but you can also contact us for a quote on a pre-wired system, complete in a metal Nema enclosure. These take longer to produce (and cost more as well), but are available for those uncomfortable with the electronics side of CNC.
