Gentlemen,
I have recently obtained an MPG that I have been trying to connect to my Mach3 / mill. The unit is a HEDS-5700 C10 optical encoder. with 100CPR and 5v input.I have wired the unit up as per the tech data for the unit, and have tested the wiring to show that A & B outputs indicate 5v pulses when the wheel is turned.
I have connected the input wiring 5V and grd to the power connections on my CNC4PC C10 breakout board (as per their wiring diagram), and have connected the output A & B wires to pin nos 13 and 15 on the board. In Mach 3 I have enabled MPG#1, selected port no 1, pin no 13, then port #1, pin no 15, I have left the steps set at 2 (as indicated for 100CPR in the Mach3 manual), and the velocity to 100. I have used the Tab key to bring up the jog/mpg screen, set jog to MPG,
selected Step/velocity for jog type, and axis 1 to X. When I turn the wheel I get no response. When I go to the diag screen and move the wheel no leds light up in the pin status. When I checked the voltage on the pins 13 & 15 while they where disconnected from the breakout board I got 4.86 volt signals from the A & B wires, but when they were connected to the breakout board the max signal was .8 volts. After stumbling across the calibration screen for MPGs in Mach3, when I run through the process, all the settings came back 0. I assume it is because Mach3 is not getting a reading from the MPG, but as I can get a 5v signal out of the unit, I cant see what is wrong, and as I'm not exactly an electrical genius, cant figure out what I have missed. Please can you offer some help as I really want to use this unit on my mill. THANKS for any assistance.
A SAFE and happy holiday to all.
