Yes the fan should start up straight away so check the 12v supply and wires to the fan. The recommendation of many is to not go beyond 24v so that is fine. Can you supply the details of your steppers and how you have them wired as this will help in diagnosis. List the connections you have made and any config settings in Mach3 would help also. I am afraid i use EMC2 so can not run through the config of Mach3 with you but i am sure somebody else here can validate that for you

Hello,

ok, thanks Y/Z Axis working. X not working. I figured out that i have permanent -0.22V out of PIN 1 (X-step). While for Y and Z i have 0 V and -0,02V when axis is moved. So does anybody knows why i have these -0.22V permanent output ? The DIR PIN for X axis is working - so only the PIN 1 is the problem. I checked in mach, an no other functions are related to PIN 1.

Thanks for any input - step by step t will work someday..

Regards from Germany
Andy

Did you get your X working as I have the same problem? also anyone notice the pin outs on the board for the steppers are different to the instruction sheet which is right?

Hi,

yes now everything is working. I took a different computer and voila ! First i did use a Fujitsu Siemends Laptop - X Axis not working, now i use IBM Thinkpad - and everything is nearly fine. For Christmas holiday i want to get a cheap second hand desktop pc to get the full 5 V out of the parallel port.

Anyway - my x-axis is still sometimes losing steps. I don´t know if this is a general problem with this chinese board or if there´s a mechanical problem. But each day my machine gets better...

Good luck
Andy
