EUREKA I have movment. Well y and z movements. Have found out how to jog and it seems that I now have a problem with the port on the mother board. Step gives me 4.3 volts and dir 0.09 and changes to 0.091 when a direction is enteredwith the jog. Has any one come accross this before?

Hi Hood, Have check continuity of the cable and all is good. am going through the motions of testing the signals but not being able to jog makes it a bit hard. How do I get the jog working to test out the motion?

aye Hood How you going? I have voltages but they're all over the place. step pin on x is 4.3v direction pin @ 0.9v dont quite know how to jog in plasma yet but have ran a file i created on g code and voltages are constant on x but vary on y and z might look at chnging pin addresses

Geelong, Victoria, Australia. Bet the weather is better than here at the moment. 9deg C and wet and windy.

Thanks Chip, I went through the screens you sent but nothing seemed to work. All settings were as you had described except for the sherline half step that did nothing so left it as it was. There has to be something that I have missed somewhere. I have been through all the documentation again  and there is something i am overlooking.
Thanks again Chip. Where are you from?

Hi Woffler, thanks for the reply. the motors are locked up when the power is on and free to turn when the power is off

Hi Guys, My Name is Ron From Australia and am having problems getting my steppers moving. I had problem previously with a add on parallel port card that Hood helped me out with, Thanks Hood. Now have a new mother board with a built on parallel port and have configured the port and the pins step and Dir as per the mach 3 manual. I have a mechtronics 4 axis breakout board (www.easy-cnc.com for the manual)and 4 japan servo hybrid steppers which i wish to put on a plasma cutter. I have configured the pins and direction for the motors and configured for mach driver test and all seems to be working ok there. I have learnt to read and write g code over the last month and simulating it on Mach 3 with great success but have had nothing to do with the nuts of cnc setup. I am a toolmaker by trade with little electronics knowledge. When the power is turned on the motors briefly pulse and that is all I can get out of them. They get really hot after about an hour of testing. I have set the on board current set up to the the 1.8A for the motors as per there spec sheet. I have set the steps on the motor tuning to 2000.

I do not get any signal on the port 1 pins state. Pulse freq is about 33500 with kernel speed of 35000

Port is 378 as per the get port address function Hood put me on to and motor outputs are as per the mechtronics manual.

I am obviously missing something or have not checked or unchecked a box somewhere.

Does anyone have any Ideas to get me started? Thanks Guys.

Thanks for the efforts Hood. Have downloaded lastest drivers and nothing changes. I will attempt to get a new PCI Parallel card and see if that makes the difference or may have to build a new computer with an motherboard based Parallel port. Thanks again Hood. Appreciate the time. Will probably need a bit of help to get it set up once I get the Breakout board and the Computer talking to each other.

Hi Hood, Tried that and there is nothing under the parallel port although the PCI card is in the I/O of hardware resources. It is a hex code but none of them seem to work the CNC card. Any ideas on how to the get the computer to recognise the PCI as Parallel port? might fix the problem.
