FREE USB-Parallel Port Interface
Released 08/03/2006 - Updated 12/03/2006.
Do you drive your Motor Controller usually via the Printer Port?

Well now you can convert it to USB with this very simple Circuit below.

We supply the PCB design FREE, the Firmware FREE and the Windows Application FREE.
You just build it, use it and let us know of any improvements we can make.
To compliment our new FREE Beta USB Application (Shown Below) along with new Firmware, we are going to release a very simple circuit that people can build themselves that will let you control any parallel port stepper motor controller via USB.

With this simple circuit and our Firmware you will be able to simply plug it into your existing Controller box and using our software, run your Gcode via the USB Port.
The reason this will work with any existing Controller box that uses the parallel port to control the Clock and Signal lines is because we will release standard Firmware that will cover different pin configurations as needed.

If your controller has a different configuration then just email us and we will customise the Firmware to suit your needs and release it on this site. In doing this we hope to build up different configurations to suit all different kinds of controllers out there.

And a PCB about 75mm * 75MM

Firmware Version 1.2 released 12/03/2006:

Click here to download the Firmware Version 1.2 Type1. (http://www.overunity.org.uk/cncdudez/USB-PAR-FirmwareV12-type1.zip)
This code is for use with the 18F4550 Pic Chip.
You will need a suitable Pic Chip programmer that supports the 18F4550.
The fuses have all been set in the hex file, so simply load up, Program and Verify.
Type 1 is configured for the following Pin Configuration:

Pin2: Step X-Axis
Pin3: Direction X-Axis
Pin4: Step Y-Axis
Pin5: Direction Y-Axis
Pin6: Step Z-Axis
Pin7: Direction Z-Axis
Pin10: Z-Limit Switch
Pin11: Emergency-Stop Switch
Pin12: Y-Limit Switch
Pin13: X-Limit Switch

As we have said before, if you need the firmware customised to suit your controller then please email us and we will re-compile and release here.
Command Structure for Firmware:
Command Structure Ver 1.2 upwards:
Commands are sent 11 bytes at a time.

This first byte gets broken down into 8 bits and they do the following:
bit0= X Axis Direction
bit1= Y Axis Direction
bit2= Z Axis Direction
bit3= Travel kind, this is for the firmware to tell it to use different routines for G00 travelling or G01 cutting, 1=Travelling 0=Cutting
If you set this bit to 1 then the firmware will not care about how it gets to this position and it will just clock each Axis until it gets there.
If you set it to 0 then it will move the X and Y axis at even pulses to get to it's destination giving the correct line needed. This option takes more processing time, so speed pauses may have to be adjusted.
bit4= Tells Firmware to ignore limit switches 1=ignore 0=do not ignore
bit5= always 0
bit6= always 0
bit7= always 0

Lee Roberts
11-11-2008, 07:06 PM
The next 3 bytes control how many pulses you wish to send to the X-Axis.
On our machine 533.333 pulses =1mm so to tell it to travel we first have to round up and break to binary int(533.333)=533

533 binary= 00000000 00000010 00010101

now we get our 3 bytes from this

1st byte 00000000 = 00
2nd byte 00000010 = 02
3rd byte 00010101 = 21

By doing it this way we can send a max 16777215 pulses which = 31457MM (103 feet!) Travel

The next 3 bytes control how many pulses you wish to send to the Y-Axis.
This is the same as the X-Axis
The next 2 bytes control how many pulses you wish to send to the Z-Axis.
Same as the X-Axis but this time only 2 bytes(16bits)
Final 2 bytes is Pulse Width Delay
0050 = Pulse delay in Microseconds for speed.
This will differ depending on the Step Mode that the controller box is set to.
Find some examples below, obviously we round up because we only send 4 digits to the controller.
Eighth Step Timings:
A 2250 Microsecond pause gives 25.4mm or 1 Inch Travel per minute.
A 1125 Microsecond pause gives 50.8mm or 2 Inch Travel per minute.
A 0562.5 Microsecond pause gives 101.6mm or 4 Inch Travel per minute
A 0281.25 Microsecond pause gives 203.2mm or 8 Inch Travel per minute
A 0140.625 Microsecond pause gives 406.4mm or 16 Inch Travel per minute
A 0070.3125 Microsecond pause gives 812.8mm or 32 Inch Travel per minute
A 0035.15625 Microsecond pause gives 1625.6mm or 64 Inch Travel per minute
A 0017.578125 Microsecond pause gives 3251.2mm or 128 Inch Travel per minute

So to work out what pause we needed for say 45IPM we would use 2250/45 which gives us 0050
To work backwards and see what a pause of 50 would get, we would take 2250/50 which would give us 45IPM.
The motors we use on the CNCDuDeZ Frame max out at about 50 Microsecond pause, which gives us a respectable approx 45IPM!
Quarter Step Timings:
A 4500 Microsecond pause gives 25.4mm or 1 Inch Travel per minute.
A 2250 Microsecond pause gives 50.8mm or 2 Inch Travel per minute.
A 1125 Microsecond pause gives 101.6mm or 4 Inch Travel per minute
A 0562.5 Microsecond pause gives 203.2mm or 8 Inch Travel per minute
A 0281.25 Microsecond pause gives 406.4mm or 16 Inch Travel per minute
A 0140.625 Microsecond pause gives 812.8mm or 32 Inch Travel per minute
A 0070.3125 Microsecond pause gives 1625.6mm or 64 Inch Travel per minute
A 0035.15625 Microsecond pause gives 3251.2mm or 128 Inch Travel per minute

Half Step Timings:
A 9000 Microsecond pause gives 25.4mm or 1 Inch Travel per minute.
A 4500 Microsecond pause gives 50.8mm or 2 Inch Travel per minute.
A 2250 Microsecond pause gives 101.6mm or 4 Inch Travel per minute
A 1125 Microsecond pause gives 203.2mm or 8 Inch Travel per minute
A 0562.5 Microsecond pause gives 406.4mm or 16 Inch Travel per minute
A 0281.25 Microsecond pause gives 812.8mm or 32 Inch Travel per minute
A 0140.625 Microsecond pause gives 1625.6mm or 64 Inch Travel per minute
A 0070.3125 Microsecond pause gives 3251.2mm or 128 Inch Travel per minute
Full Step Timings:
Use below full step for speed of 25.4mm or 1 Inch Travel per minute.
A 9000 Microsecond pause gives 50.8mm or 2 Inch Travel per minute.
A 4500 Microsecond pause gives 101.6mm or 4 Inch Travel per minute
A 2250 Microsecond pause gives 203.2mm or 8 Inch Travel per minute
A 1125 Microsecond pause gives 406.4mm or 16 Inch Travel per minute
A 0562.5 Microsecond pause gives 812.8mm or 32 Inch Travel per minute
A 0281.25 Microsecond pause gives 1625.6mm or 64 Inch Travel per minute
A 0140.625 Microsecond pause gives 3251.2mm or 128 Inch Travel per minute

Every time you send a 11byte command you will get 2 bytes back from the controller that will give you in ASCII the answer OK. This is the same whether sending Serial or USB.
You will also get a 2 byte ASCII code sent back for AUX1 inputs which are triggered:
XL X-Axis Limit Reached
YL Y-Axis Limit Reached
ZL Z-Axis Limit Reached
XY X-Axis and Y-Axis Limits Reached
XZ X-Axis and Z-Axis Limits Reached
YZ Y-Axis and Z-Axis Limits Reached
XA X-Axis, Y-Axis and Z-Axis Limits Reached
ES Emergency Stop Activated.

Application:

Please Check the USB-Software link to download our Beta Application. (http://www.cncdudez.com/cncdudezsoftware.html)
http://www.overunity.org.uk/cncdudez/screenpcb.jpg
Setting up and testing:
After you have assembled your new Interface, simply plug in a USB lead and Windows XP will automatically detect the Interface as a USB Hid Device.
You can confirm this by checking in device manager of your machine.
Now connect your Printer Port cable from the Interface to your controller box and you are ready to go.

Run up the software, set up the pulses per MM parameter and try out the Jog.

Please make sure you read the HELP File first.

I've done a (very) quick hash at a schematic - with a few revisions:

The PIC to be programmed in-circuit with a PICkit2 or PICkit3. You'll need to make sure your CNC device is unplugged when you do this (since it pings a couple of the pins), and also don't press the switch when you do it!
The >400nF capacitor has been included
The component numbering has been altered


The new layout is smaller, and doesn't have any wire jumpers. However, it is designed primarily for photo-etching (the .zip file contains the PDFs for the schematic, layout and PCB itself, at a 1:1 scale - I use the latter for my photo-etching of boards).

If you want to remain faithful to the original design (i.e. you don't need the ICSP header), then you can replace D1 with a wire, and remove PL1.

If this treads on anyone's toes, please let me know.

Does the computer make the "dee-dum" noise when you plug it in/unplug it? If not, you have not got a working USB interface.

As it is HID rather than Generic Serial, did it ask for the .inf file location when you first plugged it in?

Robin Hewitt
09-06-2010, 10:56 AM
If any USB device makes the noise, they all will.

The computer finds a USB device and gets it's unique product ID number. Then it goes "dee-dum" and looks for software matching that number.

No noise means there is a problem in the firmware or the hardware.

Product ID numbers are a problem if you want to make USB devices. The numbers are free but you have to join the USB club to get them which costs about 3k IIRC. When I needed numbers I searched the web and found a USB club member wanting to sell me ten numbers for a hundred pounds or so which is how I got around it. Wonder what number you are using.

irving2008

The USB device ID is a combination of device, interface and endpoint configurators. These are set by firmware after the PIC is reset and then the sequence is:


When the device is initially attached to the bus, the host
enters an enumeration process in an attempt to identify
the device. Essentially, the host interrogates the device,
gathering information such as power consumption, data
rates and sizes, protocol and other descriptive
information; descriptors contain this information. A
typical enumeration process would be as follows:
1. USB Reset: Reset the device. Thus, the device
is not configured and does not have an address
(address 0).
2. Get Device Descriptor: The host requests a
small portion of the device descriptor.
3. USB Reset: Reset the device again.
4. Set Address: The host assigns an address to the
device. >> this is where the de dum sound occurs
5. Get Device Descriptor: The host retrieves the
device descriptor, gathering info such as
manufacturer, type of device, maximum control
packet size.
6. Get configuration descriptors.
7. Get any other descriptors. >>during 5,6,7 Windows refines its understanding of the device, this is where you'll see 'Found generic HID' followed by 'Found <some device class>'
8. Set a configuration. >>this is where windows tries to load the required software

Since the ProductID is expensive the specifics are often in the later configurators, using a generic ProductID at the top level.

If you are unable to get Windows to recognise the USB device, you could try downloading a USB diagnostic tool (http://www.softsea.com/review/USB-Monitor.html). Does the device appear in Device Manager as an 'Unknown device' with a yellow question mark? If so then Windows is not recognising the descriptor as one of the generic classes. If it doesnt appear at all then the USB controller isnt able to do the initial reset/enumeration (steps 1 - 3 above) and Windows will never know the device exists. If this is the case then the problem is in your hardware or software (including the Microchip USB libraries) and without a full scale debugger and source code and the knowledge to use it there is little anyone can do to help.

I just had a quick look on www.usb.org (http://www.usb.org) and it seems you can now get vendor ID numbers for a mere $2k.

Not as bad as I remembered it but they've now added a clause to say you can't sell numbers on. Too late guys :naughty:

tribbles
12-06-2010, 12:39 AM
If you're using a Microchip product (which this is), then you can apply for a PID and use their VID - although if usb.org has changed their rules, then I don't know if it's still applicable (I did download their application form a week ago though, so it's not been removed - but then I did find a direct link to it off another website, and they may have not removed it; only their links to it).

Hello Lee,
i'm currently working on a software that should control 4 motors for a wire machine using our software, see the software here
http://www.youtube.com/watch?v=WzB3aYCwk8g
we really would like to sell the software with a dedicated hardware for controlling the 4 stepper and the question is
if your development could be used as a starting point for this and how much it would cost.
As you can see, we need 4 motor axis direction control, and we could use some others i/o for heating the wire and limit control.
if you have interest in this project please contact me at philip_hubert@mac.com
Thank you for your time

In the first place happiness for their project. I am a student that I would like to carry out this badge USB. The problem is that my parallel port is different and therefore I cannot make it. My parallel port is the following one:

Pin1 X Step
Pin2 Y Enable
Pin3 Y Dir
Pin4 Z Dir
Pin5 Z Step
Pin6 Z Enable
Pin7 X Dir
Pin8 Y Step
Pin9 spindle MOTOR
Pin10 X Home
Pin11 Y HOME
Pin12 Z HOME
Pin13 EStop
Pin14 X ENABLE
Pin15 EXPAND
Pin16 EXPAND
Pin17 EXPAND
Pin18 to Pin25 GND

The Firmware could send me for the PIC 18F4550.

THANK YOU

I know how to control them using 8 PINS of the Parallel port and also using the Assembly language to create sequence of each LEDS/PINS., but what i want is, i want to control them using USB. Is this module that you have created can possibly control the LEDs?
I need your help sir. :(

Hi
I need to convert this parallel board to USB but the firmware codes aren't suitable for it. Each pin of the parallel port goes through a Fet directly to the a coil of a motor. It controls 2 unipolar stepper motors. As you say if one needs a diferent firmware you could change it and post it here, I kindly ask you to do so.I attach the board for your reference . Thanks
