### Question #: 744

Question: How do I configure my control program (i.e. Mach3, EMC2, etc.) for roller chain or timing belt steps per inch?

Current Solution

First, you will need to know the pitch of the roller chain, or timing belt. For example, #25 roller chain is .25" (1/4") pitch and #40 roller chain is .5" (1/2") pitch. Timing belts are similar and you will need to search the specifications of your particular drive pulley pitch. Take this pitch and multiply this with the number of teeth on the drive pulley/sprocket. This will give you the number of inches around the pulley/sprocket. Now, take the number of steps per revolution that the motor will output. This will be the number of full steps that you motor produces (typically 200, or 1.8 degrees per step) multiplied by the microstepping per step to which the driver is configured. Divide this number by the inches that was calculated from the drive pulley/sprocket. Here is an example: If the motor produces 200 steps per revolution and I am driving it at 1/16 microstepping and my sprocket pitch is .25" with 9 teeth, my formula would be:

(200 steps * 16 microsteps) / (.25 inches * 9 teeth) = 3200
steps per revolution / 2.25 inches = 1422.222 steps per inch

### Other Possible Solutions to this Question

• How do I configure my control program (i.e. Mach3, EMC2, etc.) for lead screw steps per inch?

You will first need to derive the number of turns per inch that your lead screw produces. If there is only a single start (typical all thread screws), then the turns per inch is the same as TPI (threads per inch). If there is multiple starts, then the number of starts is divided by the TPI to determine the turns per inch. For example, 10 TPI with 5 starts is 10 / 5 = 2 turns per inch. Now that we know this, we can get the number of steps per inch as described in the previous question: take the number of steps per revolution that the motor will output. This will be the number of full steps that you motor produces (typically 200, or 1.8 degrees per step) multiplied by the microstepping per step to which the driver is configured. Simply multiple the number of turns per inch and the number of steps per revolution and you will get the steps per inch. Ok, lets see the formula:

200 steps * 16 microsteps * 2 turns per inch = 6400 steps per inch

how do I determine the steps per inch for the motors?

• How do I order the 10 TPI 5-start 2-turns-per-inch screws?, just shows \$ per inch with no option for lenght.

When purchasing the 1/2" 5 start lead screw, the length is based on the quantity. Specify the total length you will need and we will email you (if you don't contact us first) to determine the cut lengths.

For example, if you desire 36 inches of lead screw for the X axis and 12 inches of lead screw for the Y axis, just purchase 48 inches of lead screw and tell us you need this lead screw cut so you have two lengths at 36 inches and 12 inches.

How do I order the 10 TPI 5-start 2-turns-per-inch screws?, just shows \$ per inch with no option for lenght.

• WHAT IS THE FORMULA TO DETERMINE STEPS PER INCH OR RESOLUTION FOR EACH AXIS?

The formula and calculation is a starting point to get into the area of steps per inch. You will then need to use the mach3 calibration utility to get the exact steps per inch.

Formula:
step per inch = (motor steps * microstepping) / (travel at one turn of the motor in inches)
if microstepping is set at 16 (1/16 on the driver) then and you are using a sprocket and chain with a pitch of .25 inches and 12 teeth on the drive sprocket
= (200 * 16) / (12 * .25)
= 3200 / 3
= 1066.666 steps per inch

For lead screw that has a travel of .5 inches at one turn like the 5 start 1/2 inch lead screw and using 4 microsteps per step (1/4):
= (200 * 4) / (.5)
= 800 / .5
= 1600 steps per inch

Remember to use the mach3 calibration wizard and double check the driver microstep setting.

Repeatability is very good for these machines and can be as low as .001" depending on the way you control the machine. If you use the spindle, you can be moderately aggressive, but you will want to use a finishing pass to make sure the edges are exactly what you would expect. since this is a kit, there will be varying levels of repeatibility depending on how well the kit is assembled and maintained. Calibration, as with all machines, is a critical aspect of keeping repeatibility over time.

Timing belts and chain are about the same when it comes to precision as long as the chain wraps most of the drive sprocket. There are differences to each of these systems as Kevlar with steel cables impregnated within the Kevlar and the steel used in roller chain have different coefficients of linear expansion (the expansion and contraction over temperature change), and roller chain may stretch over time, so it is important to maintain the machine by tensioning the chain and timing belt, and calibrating the machine over time and when the temperature changes significantly.

Is there a significant difference between timing belt and chain drive systems?

HOW DO DETERMINE THE STEPS PER INCH

• I ordered a redLeaf with Mach3 installed. Do you guys configure any of the setting in mach3 or will I need to do that all myself?

The redLeaf CNC computer systems will have either Mach3 or LinuxCNC installed as per the customer's request. If the Mach3 license is purchased, the license file will also be installed on the redLeaf CNC computer system.

The Mach3 or LinuxCNC settings will be configured during the assembly of the system. We contact the customer to determine the drive (mechanics) and inertial (weight of gantry and other parts of the gantry) specifications in order to correctly configure the steps per inch, velocity and acceleration.

I ordered a redLeaf with Mach3 installed. Do you guys configure any of the setting in mach3 or will I need to do that all myself?

• how do I connect my spindle to mach3 so mach3 can control it

It is not necessary to connect the spindle VFD (Variable Frequency Drive also called an Inverter) to the computer or CNC motion electronics. The VFD can be controlled independently using the control panel on the VFD. The control panel has the ability to control all aspects of the spindle including Speed, Torque, limits, etc. However, you can connect the VFD to the computer so the CNC control program can control the spindle during the CNC Machine operation. You will need to connect the VFD to the computer via a serial conection (in this case, it is the RS-485 protocol).

The following are instructions on how to connect the VFD to Mach3 via this RS-485 serial connection.

The first thing you will need is the dynamic link library to pair with mach3 called the Huanyang VFD Mach3 PlugIn. You can find this file at the mach3 support forum here: http://www.machsupport.com/forum/index.php/topic,14182.0.html

Follow the pdf that comes with the library file, but here is a synopsis of what you need to do (I also added a lot more information that may be useful during this process as the manual does not cover the main connections that need to be done):

You will need to program your VFD so that it knows how to communicate with mach3 and the computer (go into the programming mode of the VFD and change these parameters):
- PD001 - value 2 - Enables with communication aspect of the VFD
- PD002 - value 2 - Enables frequency control from the communcations port
- PD163 - value 1 - VFD address
- PD164 - value 1 - Baud rate of 9600 (speed of the communication)
- PD165 - value 3 - 8N1 RTU - 8 bits (that's the size of the word that gets communicated), N (No parity or no error checking) and 1 (1 stop bit)

Copy the dll file to the PlugIns folder of mach3.

Connect the RX and TX lines to your computer. There are a couple ways you can do this, but the recommended way would be to use an FTDI USB device which converts a USB to a serial com port. The device will have Rx and Tx connectors to connect to the VFD terminals with the same labels. This method is recommended since serial ports are not as common in computers these days.

Next, you will need to configure mach3 to use the plugin library. Start mach3 and click on Menu -> config ->Config Plugins. Enable the new plugin by clicking on the red cross on the left column next to the plug in. Restart mach3 after doing this.

No you need to configure mach3 to use the HuanyangVFD plugin. Go to the ports & pins configuration and select the spindle setup tab. Make sure that the Disable Spindle Relays checkbox is unchecked. We don't want mach3 to output a signal for a relay since the spindle will start up and turn off within the VFD and not from an external relay.

Next, go to the HuanyangVFD settings by clicking on Menu -> plugin control -> HuanyangVFD. Set the parameters to the same settings you put into the VFD programming. The com port will be shown as new hardward when you plug in the USB FTDI device. A little bubble will be displayed at the bottom right where it will notify you that a new device is being installed (be patient while windows assigns a com port). Alternatively, you can use the windows device manager to see which port was set for the new USB FTDI device). You may need to restart mach3 several times until you get the correct information displayed in the PD001 and PD002 fields. When the com port is correct and the other parameters, like baud and VFD address is the same as you entered in the programming, then the PD001 and PD002 will show the number 2, otherwise, a 99 will appear which means that communication was not successful.

You can now control the on/off and RPM of the spindle using the RS485 communication between mach3 and the VFD.

The question was how to connect the spindle to the redfy. I did not receive a VFD.
I have the redFly system and a 2.2kW Spindle - 110V how do i connect the spindle?

Hi, how is this setup in mach4?

how do I connect my spindle to mach3 so mach3 can control it

• I have your mach3 USB BoB, do you guys sell a torch control relay I can wire up to turn my plasma torch on and off and how I would wife that too this BoB?
• I have a BlueChick that came with the 5-Axis Bread-Out Board V5 (parallel port), it has 3xCW230, how to configure it on LinuxCNC?

Strictly to the point. Assuming:
-You have a working linuxcnc install with a compatible parallel port
-You have wired Bread-Out Board V5 to the motor drivers so you know which pins are for which signals(watch video tutorials for that on this site)
-You have wired motors to motor drivers (watch video tutorials for that on this site)

a)We need to know the base parallel port addres, for that you need to input on a linux terminal the command:

#lspci -v

You can scroll up and down the result with page up and page down. Look for a "Parallel Port..." line, the value you are looking for is the "I/O Ports at.." Write them down

To get the Base Period Maximun Jitter, go to
applications - cnc - Latency Test

Now you should let that window running for a while, so it calculates an accurate jitter, go watch the tutorial videos for the connections between the Bread-Out Board and the motor controllers.

After its been running for half an hour or so with the machine in use, write down the calculated jitter values, mine was Servo Thread - 39000

Now close the Latency test dialog

b)Go to applications - cnc - stepconfwizard
"START" - Create a new config
Check - Create Desktop Shortcut to config files
Check - Create Desktop Shortcut to start linuxcnc with this config
FORWARD

c)"BASE INFORMATION"
Fill in a Machine Name that suits you
Bluechick is XYZ on inches
Fill in the Base Period Maximun Jitter with the value obtained in "a)"

FORWARD

d)If you watched the tutorials on a) and b) you know the pin numbers for your signals.
Parport Base Address you need to put the value obtained in a), mine was cf00
Output pinout presets I used Sherline

FORWARD
FORWARD

e)Axis X (chain and sprocket axis)
Data for bluechick from build yourcnc
Motor Steps per revolution 200
Microstepping 64 (that if you followed tutorials, change if you have different)
Pulley teeth 1 ; 1
Leadscrew Pitch 0.444444 (that value comes from 1rev / (.25 in * 9 teeth))
Maximun Velocity 10
Maximun Acceleration 0.5
Home location 0.0
Table travel 0.0 to 34.0 (maybe you want to change this later)

Now, you can do "Test this axis" and jog it (move it!) Try to position everything in the middle (you will be doing it axis by axis) and select
"+ 0.5 in" Hit run, I used a pencil held at the gantry and paper to draw a line, then confirmed that the measurement was 0.5 in. Also tried with "+/- 0.5 in" and confirmed 1" measurement

FORWARD when happy with your Axis X

Repeat for Axix Y but the table travel is 0.0 to 12.0

f)AXIS Z
With data from buildyourcnc.com
Motor Steps per rev 200
Driver Microstepping 16 (as recommended for lead screw)
Pulley teeth 1 ; 1
Max Vel 2.5
Max Accel 0.5

Table travel 0.0 to 3.5

Test, and FORWARD when happy

g)After configured you can go to
Applications - cnc - LinuxCNC, and there you go...

... Still think that there should be a tutorial for this part.

oh¡ Forgot to tell, the config shortcut will be available on our Desktop, launch linuxCNC from there

• 3d printer motors not moving fast enough. How should I configure the motor drivers?

This will depend on the 3D printer that you are using and the mechanics involved. Specifically regarding the motor drivers, software is really what determines the speed of the motor. If the computer is not able to product the high number of pulses that is required for faster motion, then you can reduce the microstepping and configure the software appropriately for the new microstepping so the resolution is corrected (steps/inch or steps/mm).

3d printer motors not moving fast enough. How should I configure the motor drivers?

• How do I control stepper motors from my computer?

All you need is a CNC controller like the following options:

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

This controller is easy to connect using standard wire screw terminals and works with the mach3 control software.

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

This controller is a little bit more difficult to connect, but is a more feature-rich controller and will work with both mach3 and mach4 CNC control software titles.

Specifically, a CNC controller connects to the computer via a USB cable and connects to the motor drivers. These controllers also connect to the limit switches, spindle/router control, air/fluid/mist control, etc.
