Re: mistake in the 3-axis stepper motor controller : Page10

There is a limitation for the parallel port. It support two home switches only: X, Y
For other limit, you use Mach3 'soft limit' to handle it

Re: UP-8135A question

Simply connect a 7805 is not a good idea. You need to add a couple caps to do noise filtration. For high voltage application, you may consider my HV 5V module which support 7~60V input and output 5V (another model support 12V)

Re: RF4A 4 channel RF control system question

Please do more research on relay. A relay doesn't provide any voltage unless you inject to. It's either Open Or Closed contact. It's a mechaniic switch to control on and off action. A switch does not output votlage itself

Do not use under rated PS as the PS will get very hot if you do so. Make sure to download the manual I posted under the Manual Catagory and...

It's current limited, so you really don't need to care about the 3.6V. Just make sure that the motor is running the current the board being set to
