G0704 Electronics

This page will cover several electronics packages that will work for the G0704.
I'll start with the components that I plan to use and add some more that can or are being used sucessfully by others

Hoss CNC package - This runs at 50 Volts and 5 Amps

(3) KL-6050 Bipolar Stepper Motor Drivers  $49.95  /  $149.85
(3) KL23H2100-50-4B (3/8 Dual shaft with a flat) 570 oz-in  $54.95  /  $164.85
(1) KL-600-48 48V/12.5A Power Supply $129.95 or Kl-4813 48V/13A Unregulated - $139
(1) C10 Bidirectional Breakout Board $28.04

Option A Total = $472.69 to $481.74

Note: I've done many tests running all 3 Axis' off of this power supply from Keling.
KL-350-48 48V/7.3A
110V/230V  $49.95
It has proven to work quite well even at full speed so it can be considered a viable option
to use instead of the 12.5 Amp supply listed above. Watch the Video here.
The Gecko rule for power supply selection is total motor amperage times .6.
For (3) 5 amp 570's the power supply amperage would be 15 x .6 = 9 amps.
I'd still go with the 12.5A if you plan on adding a 4th and 5th axis.

Option B Total = $392.69

A good middle of the ground switching power supply would be this.
KL-480-48 48V/10A $99.95

Option C Total = $442.69

Keling has new Digital drivers that offer many new features like Motor auto-identification,
Mid range Anti-Resonance and idle current reduction.
Use (3) KL-5056D instead of the (3) KL-6050's.

Option D Total = Add $150 to the cost of the other Options.

Note - Alternate Sources:
Keling may have a shortage on the KL-6050's and 570 oz/in motors from time to time,
I've shown these to be a superior combination, fantastic performance at a great price.
They've become very popular.
Similar 60 Volt 5 Amp drivers and 570 oz/in motors can be found from the following vendors.

While you're at Automation Technology Inc, pick up an E-Stop switch, couplers,  parallel cable, motor cables, limit switches, etc. for any package shown.
Make motor cables using DB9 connectors from Computer Cable Store.
DB9 Solder Connector - Female (6-3 axis,8-4 axis)
DB9 Solder Connector - Male (6-3 axis,8-4 axis)
DB9 / HD15 Plastic Hood (9-3 axis, 12-4 axis)
or some XLR connectors from Probotix. or much cheaper at Futurlec.
Get excellent shielded oil resistant CNC cable from McMaster Carr, part #8082K81
or some 18 or 22Ga shielded cable from Probotix.
I used this relay from Davis Instruments for my Flood and power drawbar, etc.
Opto 22 Z-Series Solid State Relay also available at Allied Electronics.
(3) Moujen MN-5311 Mini Enclosed Limit/Home Switch  $11.50  /  $34.50
or some cheapo microswitches from Circuit Specialists
or some nice inductive proximity switches from Cnc4pc.

Attention! - Cnc4pc has come out with a new BOB and adapters that use RJ45 cables
to connect the BOB to the Keling drivers. Makes wiring a piece of cake.
Would only add $29.68  for the C35 BOBC34KL adapters, and A26 RJ45 cables.
Note that there are different adapters for others drivers including the digitals.
These are also available at Automation Technology Inc.(Keling)


Optional CNC Electronics Packages


Hoss Heavy Duty
- This is a Hybrid package that will give you the most torque
to all axis' without wasting money on components that aren't being used to their potential.
Tons of grunt for the heaviest duty milling. A Nema 34 Z axis stepper raises the head easier if you add extra weight to it with a larger spindle motor, aux. spindle, power drawbar etc.

(2) KL-6050 Bipolar Stepper Motor Drivers (X and Y)  $49.95  /  $99.90
(2) KL23H2100-50-4B (3/8 Dual shaft with a flat) 570 oz-in  $54.95  /  $109.90
(1) G201X  7A, 80VDC (Z axis) - $107 or KL-8060  Bipolar Driver $96.95
(1) KL34H295-43-8A  NEMA 34 STEPPER MOTOR 906 oz-in (Z axis) $99.00
(1) KL-600-48 48V/12.5A Power Supply $129.95 or Kl-4813 48V/13A Unregulated - $139
(1) C10 Bidirectional Breakout Board $28.04

Total = $563.74 or $572.79


Hoss Digital Package - Look out Gecko, Keling has some new stepper drivers that are digital vs. analog. These high performance drives should become very popular in no time.
They offer Anti-Resonance, Motor auto-identification and parameter auto-configuration technology, Multi-Stepping allows a low resolution step input to produce a higher microstep output for smooth system performance, motors can run with much lower noise, less heating, and smoother movement. Rapids speeds much higher than with an analog drive.

(3) KL- 5056D Digital Stepper Driver  $99.95 / $299.85
(3) KL23H2100-50-4B (3/8 Dual shaft with a flat) 570 oz-in  $54.95  /  $164.85

(1) C10 Bidirectional Breakout Board $28.04  or  C11 - $129

Total = $622.69  to  $732.70

Note: adjust KL-60048 power supply to 45V output with onboard pot.


Hoss Heavy Duty Digital - This is package will give you the most torque
to all axis' with ease of installation and wicked rapid speeds.
Tons of grunt for the heaviest duty milling. A Nema 34 Z axis stepper raises the head easier if you add extra weight to it with a larger spindle motor, aux. spindle, power drawbar etc.

(1) C10 Bidirectional Breakout Board $28.04  or  C11 - $129

Total = $686.74  to  $796.75

New!
MX3660 3-axis Digital All-in-one Drive  - This new driver is like the Gecko g540 with an
integrated break out board but is digital with 60vdc 6 amps, 5 inputs, 4 outputs and spindle control. Will work with any of the motors I recommend here.

(1) MX3660 3-axis Digital Driver  $259.95
(2) KL23H2100-50-4B (3/8 Dual shaft with a flat) 570 oz-in  $54.95  /  $109.90

(1) KL-600-48 48V/12.5A Power Supply $129.95 or Kl-4813 48V/13A Unregulated - $139

Total = $598.80  to  $607.85



Bare Minimum Recommendation
- This runs at 50 Volts but only 3.5 Amps
Should be easier for newbies to setup but is definitely weaker. Don't expect
to be able to hog as much metal with this setup.

(1) Geckodrive G540 4 Axis driver - $234.95
(2) KL23H2100-35-4B   381 oz-in stepper motor (X and Y axis) $49 / $98
(1) KL34H260-35-4B (1/2" Dual Shaft ) 465 oz-in   $79 *
(1) KL-480-48 48V/10A power supply $99.95

Total = $511.90

* Run with a 1.33:1 pulley ratio (24 and 32 tooth pulleys) for 618 oz/in output.

or use (3) KL23H2100-35-4B  570 oz/in 3.5A Stepper Motors $54.95 / $164.85

Total = $499.95

Total = $959.99


DMM Tech AC Servos

These AC servos are becoming popular for their good power and ease of setup.
They have several packages and individual components.
300 watts should provide a decent minimum for speeds and power with 3:1 pulley ratios
and are nema 23 so will fit the motor mounts.* see below.
I personally would go for the 400 watt package although these motors are slightly larger
than nema 23 and would need slightly larger bores and bolt patterns as shown here.
Use pulley ratio of 2-3:1 for the X and Y axis and 3-4:1 for the Z axis.
Packages listed here.
http://www.dmm-tech.com/Files/DMMTechnology_multiaxiscatalogue_Rev.1.1.pdf

Total = $1130 - $1160

* Note: Servos will require belt reduction drives for each axis 2:1 to 4:1 ratio. These can be adapted from the Phase 1 and 2 plans for the Y and Z axis but you will have to create your own for the X axis. Check out sdubfids thread for inspiration.

Keling Motor Comparison Chart

This chart shows Stepper Motors available from Automationtechnologiesinc by their oz/in size,part number, Amps/phase and max Voltage based on the geckodrive calculation "square root of the motors inductance multiplied by 32". This can make it easier when choosing a motor to make sure it is within the specs of the driver and power supply of your choice. To get the most out of your motor, you want the driver to be able to provide the amperage needed by the motor and the power supply to be as close to the motors voltage without going over. Example, a 906 oz/in 6.1 Amp motor run on a 3.5 Amp driver will only output 520 oz/in. A 50.6 volt motor will run very well on a 48 volt power supply but would overheat on a 72 volt power supply.
Note: 8 wire motors are rated as wired in the preferred Bipolar parallel mode.
 
 
 
 
 
USB for Laptops

If you want to use a modern day laptop to run your mill using Mach 3 you will need an external motion controller because Mach 3 uses the parallel port to connect to the breakout boards. Most modern day laptops if not all no longer have parallel ports. Generic parallel port adapters won't work. Compatible external controllers can be found on the Mach 3 Plugins page. The most popular is the Smoothstepper from Warp9, many use it with desktops as well. Though they have the original usb version the ethernet version is apparently better. You can get one direct from Warp9 or through many resellers like Automation Tech.
USB Smoothstepper $155
Ethernet Smoothstepper $189
USB Smoothstepper with Terminals for Mach 3 $199.98
Ethernet Smoothstepper with Terminals for Mach 3 $219.95
