Hi All,
I have been turning the handwheels for about 4 years and now it is time to change that. I located the ball screws and associated hardware and then Mach3 and then the NEMA23 stepper motors and the 3 Axis CNC Driver board and a power supply. At this point I have everything but can't verify the motion of the stepper motors.
I am running Mach3 Version R3.043.022 (the build the really bad looking green Settings screen).
The TB6560 stepper motor driver controller board is the interface between the Steppers and the PC.
http://www.nbglin.com/tb6560.htm and see below for original manufacturer (hyu68).
Motors make noise but shafts do not move. I have increased the pulse width (in Motor Tune) of the step pulse from 0 to 5 in 1uS increments. No motor shaft movement. I have tuned the motors so they sound smooth and don't jerk on the table but still no shaft movement. I have changed Acceleration and Velocity to minimal values and gone up from there and all I get are motor buzzing but no motor shaft movement.
If I turn the Slow Jog Rate to 1% or lower, the motors grind but the shafts do not move. Below 1% and the motors make a grinding noise and the shafts oscillate and but do not actually rotate.
I have been unable to get any forward or backward movement out of the motors so I have not attempted to calibrate the different axis which I will do as soon as I get rotation out of the motor shafts.
The motors are wired with Red to A+, Blue to A-, Green to B+ and Black to B- on all three motor connections.
My DC supply from Mean Well is set for 24.08V and will support up to 14.5A before dropping below 22V. The NEMA23 stepper motors are rated at 3 to 3.5A so the power supply has enough power to drive all three at the same time and remain at or very near 24V.
My TB6560 3-Axis CNC Driver board came with no information; however I have found the manufacturer and requested information. I expect the data to be what I am using for my X, Y and Z pin settings.
I found several different Port / Pin settings that make the motors make sound but none that make the shafts turn.
In searching for the correct Port Pin settings, this is what I found -
On one web page:
Axis Step Dir
-----------------------
X 2 3
Y 4 5 Y axis makes noise if 4 is changed to 14
Z 6 7
and on another:
X 1 7
Y 8 3
Z 5 4
and another setting that I found makes the motors make noise but still not move the shafts:
X 2 7
Y 14 3
Z 6 4
(This is the one I am using)

http://translate.google.com/?tl=zh-TW&q=undefined#zh-CN/en/The steppers are on a table in my house so not connected to my (future) CNC. The motors can turn forever and hit no stop. I think I have ESTOP turned off (not enabled).
I must be missing something in my configuration but after watching all of the videos and searching the web I found nothing that would make the motor shafts rotate.
I did select "inch" and wish I had left everything in "mm" as the entire setup would have been easier.
Any help in getting the motor shafts turning the way they should would be greatly appreciated by this complete novice CNC builder.
Oh, BTW, I am modifying a Grizzly MILL with parts from CNC Fusion.
My xml is attached.
Thanks in advance,
CES
