This is my first CNC experience and I'm having trouble
Whenever I try to jog the motors (XYZ) forward, it works fine, but when going reverse (negative) it moves for about a second then it seems like it "locks" then it doesn't move at all.
One time I got Z and X to move both forward and backward but when I tried moving Y, nothing happened, then X and Z won't move at all anymore. I restarted Mach3 and the machine and it"s back to it's old problem - "locking' when going reverse.
Also, sometimes they move but sometimes they don't. It's a moody machine.
Is there a problem with my settings?
(in mm)
--Pins
Port 1, 0x378 (according to my system)
X axis - Step Pin 2, Dir Pin 3 (Dir Low) (Step Low Active) Pin 1, Port 1
Y axis - Step Pin 4, Dir Pin 5 (Dir Low) (Step Low Active) Pin 1, Port 1
Z axis - Step Pin 6, Dir Pin 7 (Dir Low) (Step Low Active) Pin 1, Port 1
Probe Port 1, Pin 15, (Active Low) - not sure about this one though
Estop Port 1, Pin 10, (Active Low)
Enable1 Port 1, Pin 14
--Spindle Setup
Disable Flood/Mist relays checked
Motor Control
Use spindle Motor output checked
Step/Dir Motor checked
PWM base Freq. 5
PWM Min 0%
--Motor Tuning
X Axis Steps Per 200, Velocity 2000, Acc 200, Step Pulse 3, Dir Pulse 1
Y Axis Steps Per 200, Velocity 2000, Acc 200, Step Pulse 3, Dir Pulse 1
Z Axis Steps Per 200, Velocity 800, Acc 150, Step Pulse 3, Dir Pulse 1
Any ideas? ???

10:30 am Update: Now it won't move at all
10:33 am Update: Now X and Z move forwards and backwards, Y only moves forwards and when it moves backwards it stops after a second. Sometimes X and Z don't move too. YOu have to press them in a certain order (X+, X-, Z+, Z-) If not, they won't move at all. Any ideas on what is going on??

What machine ? , COntroller ? is it ?
(;-) TP

CNC Machine Router 3 axis 3020 (does that help?)

I tried slowing down the jog rate, still has the same problem. Sometimes it works, sometimes it doesn't. I'm kinda new to this and I'm really hesitant to explore since I might hurt something bad.

I opened up the controller and saw that whenever I move the motors, the red LED light lights up, and when I stop the red LED turns off for each motor. I notice that whenever the motors "lock" the red LED stays on, when it usually just flashes off when there is no movement. I don't know what this indicates but it indicates something

11:22 am Update: XYZ are moving both forwards and backwards!!!I didn't really do anything, I just checked the Enable1 and put it in Port 1, Pin 16, then unchecked the charge pump.
But sometimes they stuck and "lock". When one motor locks, its red LED light stays on. I'll press random motor jog buttons on Mach3, and nothing will happen for a while but after a few seconds, it starts working again. It works sometimes, but sometimes it doesn't. I want to make it work always. Any ideas on how? and why this is happening?

Any ideas? ??? I really need this to work

Can you post a link to your controller?

http://www.jinlantrade.com/ebay/3020t/IMG_1.jpg
Its like this
-
Please post specific information on exactly what you bought.
Provide a link to the site.
Did you recieve any information installation instructions? Post them or provide a way for us to look at the info.
Somehow I got the feeling that the controllers are the Chinese 3020 stuff, if so, sorry but I can't be of help and someone else will need to chime in.

Yeah I have a feeling its one of those Chinese 3020 stuff :-\ :( I forgot cause I didnt use the machine until now, I got it a few years back from ebay. Here's the manual they gave me
3 axis Mini-CNC Controller, 220V and the 3 axis CNC Router
-
But maybe it's not one of those Chinese 3020 stuff, cause i forgot what it is. The manual was just given to me, not sure if it was the one accompanying the machine
-
OK so did you setup in config/ports and pins how the manual tells you? post your xml file.
-
Sorry I'm really new to this, where can I find the .xml file?
But I set it up according to what the manual said. I didn't add anything to it or do anything.

Is this it?
