That motor weighs a couple of pounds too it is like a brick. Using the 74HC14 Schmitt Hex Inverter Trigger Chip, 10K Ohmn resistors and the 1 uF capacitor, go ahead and make the required circuit on a separate punched PCB board as per the following diagram. The fix was satisfying and complete. It was also relatively quick, cheap and most of all, EASY. It IS possible to end up with a reliable and fully functional motor driver board with only a small amount of time, effort and understanding invested. This board is a common import and the manufacturer has some common problems. And this will reduce the risk charging by local custom.The delivery status of a package can be checked via the Internet at (for tracking numbers beginning with “RA”)EUB is also known as E-packet, which is especially for delivery to USA. It takes about 10-12 days to arrive.
Just like the limit pins, these pins are held high with an internal pull-up resistor, so all you have to do is connect a normally-open switch to each pin and to ground. SeeMeCNC user notes for the 4 axis HY-TB4DV-M 4 Driver Board. This board makes SeeMeCNC machines the FASTEST available today!There are no drivers, firmware, bootloaders, version concerns, etc. It’s old school cool.

A variety of expedited shipping methods means there is a convenient delivery option for every budget. You really can’t run these drivers directly from a parallel port because they need more signal current than you can get out of most PC parallel ports.I’m sure I left out a million little details in my article but that is what the comments section is for.

Never disconnect the motor lead when the power source is energized.

Цитата(Oxford @ 9.1.2013, 5:19) Да понятное дело человек для своих задач затачивал и у него не было цели реализовать что-то там на будущее и для кого то ибо время требует это )Без сомнения.. 🙂 чисто для развлечения, как хобби.. Но хоть какая то польза от этого проекта есть! There are a number of drivers that can do this, available as fully pre-built, partially pre-built, or completely DIY. There are some examples farther down the page.
