Thanks Tramalot. I do have a picture but when I try to attach it, I don't seem to be able to post it. Do you have a private email I can send it to?

Regards,
Adrian

No, I am afraid not. I guess I should now something about what is connected to the output pins of the drive. perhaps I should try and contact the supplier for the info?

Thanks for all your efforts Hood. Unfortunately, it doesn't work yet. Personally, I feel that it must have something to do with pin allocations or something because I just do not quite understand what goes on there. For example, under "ports and pins" what does "Motor outputs" really mean? I thought that motors would only have inputs, not outputs. I don't really know what all the other columns in this table are.

At the moment I am really not too worried about steps per unit etc. Once I get the motors moving I will worry about getting them to move the correct amount.

Regards,
Adrian

Aha, yes I do. It is a Toshiba TB6560. I found a data sheet for it on ebay. I have attached it to this message.

You are correct! My apologies. There are four dip switches. Each is a bank of switches numbered 1 to 6. On each bank, the numbers 2 and 6 are set to off. The rest are set to on. Hope this helps.

The stepper motors came from Hong Kong so I guess they are Chinese but there are no micro switches. However, I found out from the data sheet that the stepping angle is 1.8 degress. Does that help?

Sorry. Not to sure about that. How do I find out?

I am not to worried about it moving the correct distance for the moment. It would be good to get it to move at all! However, the pitch of the ball screw is 5.0 mm. On the motor tuning page, the steps per is set to 2000 and the step pulse and Dir pulse are both set to 5. The stepper motors are directly mounted onto the ball screws. I hope this is what you wanted to know. Thanks again for your trouble.

The kernel is set to 25000Hz.

The pulse width and steps per unit I understood, is only relevant for servo motors. Am I wrong about that?  I have left them as they were when I installed the software i.e. 1 step per unit. I am not even sure where to set the pulse width.

Adrian

Thanks Hood, however, this does not seem to be the cause of the problem. I have reduced the speed and accelleration as far as they can go. It did certainly change the pitch. I can almost count the pulses but the stepper motors still do not turn. Any more thoughts??

Thanks,
Adrian
