Please help. Frustrated, want things to move

[Alan Trest]

Any and all advice is appreciated. I have finished the Mechanical build for a CNC Gem Faceting Machine. I bought what I thought was a 6 axis BOB from Kelling along with 6 4030 Drives. Well, guess what, the C35 only supports 4 axis. Ok, while waiting on a solution to that problem. I want to start testing the movements utilizing the C35 from CNC4PC. First pc's parallel port was toast so I built another PC which the Parallel ports test ok,. giving 3.3v and 0.0 volts per the dir testing. The 5v is being supplied with a small WW transformer which shows 5v at the BOB and at the Driver. I have the Pins set up in Mach3 for XYZ as Step 3,5,7 and Dir 2,4,6 Dir Lo (off) Step Lo (Off). I've tried just about every combination of pin settings I can and still the motors will not move. there is 36v's supplied at the motor.

Any suggestions to help would be most appreciated.

I'm having the same problem... wired up everything from the 4030/425oz kit and when I turn on the power the motors lock up like they should, but linux cnc and Mach-3 on different computers nothing turns. I know its not the parallel port (different computers) I know it isn't the parallel cable (multi-meter test). Power supply is putting out 24V to the drivers,so the only thing I can think of is the c-10 BOB. (At least one of the 4030s must be ok). Does anyone have an idea what could be wrong?

Did you set up the EMC parameter:


STEPLEN >15000ns
STEPSPACE >15000ns
DIRSETUP >15000ns
DIRHOLD >15000ns

Hello All,

I'm having the same problem...

I have the CNC 3 Axis Stepper Motor Kit with 425 oz-in motor and KL-4030 Bipolar Driver with 36V Power Supply. It also has the C10 Parallel Port Interface Card, with 5V mini adapter @ 1000mA's.

I've triple checked my wiring according the wiring diagram downloaded off the BuildyourCNC.com website.

I'm using a Windows XP workstation. I have the Mach3 software installed, it is a fully licensed copy. I've verified that my parallel port is set at 0x378 in my computer's system BIOS as well as within windows. I have quadruple checked all the settings to mimic everything outlined in the book to ensure Mach3 has been configured as required. I'm still having challenges getting my motor's to turn.

I notice that my motor's make a sound as I connect them to power. I also here all 3 of them react to the loading of Windows and the opening of the Mach3 software. They also become warm, the longer I leave power connected to them.

I have my motor's wired to the following
Red/Blue - which is wired to A+
Yellow/Black - which is wired to A-
White/Brown - which is wired to B+
Orange/Green - which is wired to B-

I've tried to follow some basic troubleshooting techniques outline in a couple different articles I've come across.
CNC Book - Build Your Own CNC Machine
Stepper Driver and Electronics for CNC Routers and CNC Machines (article on troubleshooting at the bottom of this page)

I've measured the voltages of my parallel port on my desktop computer. Pins 3, 5 and 7 all recorded 3.3volts while enabled Active High, When enabled Active Low, they measured between the range of 0.0-0.1volts (they are actually showing up as 0.01mV's on a scale of 200mV's.) If I'm correct, this tells me that my parallel port on my computer is working fine. I've tested the cable I'm using as well, which is a 25pin male to male printer cable and the voltages are consistent.

While testing the voltages on my C10 Parallel Port Interface Card, all appears to be engaged properly as my power is connected, all LED's are on, Pins 3, 5 and 7 are set to Active High, I place the red probe from my multimeter on the 5V pin and the black probe on all the pins from 3, 5 and 7. I get a reading of 1.3Volts. In the troubleshooting article listed above, Step #9, it says it should be 5.5 Volts. After a little bit of trial an error, I noticed that when the pins 3, 5 and 7 are enabled Active Low, the voltages read 5.25 Volts, when the same pins are enabled High, it's 1.3 Volts. Could this be that I have the polarities crossed from my 5V Adapter? I was pretty sure that the hot wire was suppose to connect to 5V. Could it be possible that the jumpers on the Parallel Port Interface Card were setup with an incorrect setting? I've read nothing in the instructions about what these jumper settings should be.

Any suggestions or recommendations would be appreciated.

For the c-10 rev 10.
http://www.automationtechnologiesinc...ls/KL-4030.pdf

basic wiring diagram
http://www.automationtechnologiesinc...030WithC10.pdf
this document does not show how to set the pins on the c-10

the in/out pins should be set to output or 1-2

com should be set to 2-3 making them a positive voltage

pins 2-9 not sure for this driver, but i think it should be 2-3 for pull up

pin 2 should be negative and com pins positive when active, don't test to the input voltage terminals. according to the diagram in the manual for the wiring diagram (fig 2)

Try using a switched 5v 2a power supply Automation Technology Inc, and cnc4pc carry them.
You don't need to figure out how the output is wired as they are plainly labeled which is positive and which is negative. If the voltage was reversed for the power in you could have damaged the chips on the board.

You need an e-stop wired in and configured depending on which software you are using. if you have home and limit switches configured you should have them wired in.


You also need to configure more then just what pins are connected to what axis.
