today is the day... ::o but this machine didn't want to work... nothing to do.

BUT! Today i was received a USB-paralell cable. i'll test with it...

Hi!

Today i was cutted the original paralell cable with give for the board. I went to buy another one, but not working with this board. Somebody can help on me with original or working paralell cable pinout?!

Thanks a lot!

problem solved! But the jedi dont want to work... BUT! I have a paralell switch and without the machine dont work. witch tipe of paralell do you use in bios setup?!

Good evening.

We had this same problem this WE. As I explained in an other post on the french forum, we had to replace the motors on our CNC, and we needed also to replace the driver, our old driver was not able to manage bipolar motors.

We bought a TB6560 driver and 4 NEMA 17 motors 200 steps / revolution (instead NEAM 17 100 steps motors), and as explained above, it was impossible to rotate them.

I just received a mail from one of my collegue who succeeded to run the motors.

It seems that the problem is due to differences between configuration of the LPT1 parallel port pin configuration and the TB6560 pin configuration. I don't have any supplemental information for the moment, we will install everything on our CNC on next saturday.

I will measure the speeds on all axis to compare them with the speeds estimated by Jedicut, it was my problem just before we changed everything.

Here are the connections required for the parallel lead you have to make to get the TB6560 to work correctly.

hi rob

i not understand pin10 timer input?

your mean /make external timer bord right?

please sample external timer bord

Bo

Pin 10 is the PC timer output you can make a timer if you wish I do not use one.

You can make a timer using a 555 ic.

Hello rob,

Do you have a simple schema to share ? Many people have this question :/

Here is a small timer circuit that can be constructed on a vero board. (copper strip board)
hope it helps there is a link for working out the Freq: output.

Thanks
