General Mach Discussion / Re: Spindle control in Mach3- M codes do the wrong thing

« on: October 02, 2013, 02:00:42 AM »

when I come out of the config settings Mach3 resets which is normal but this causes the spindle to start running.
Also, triggering any of the home switches causes the spindle to start up.

changing DirLowActive in motor outputs makes no difference

General Mach Discussion / Spindle control in Mach3- M codes do the wrong thing

« on: October 01, 2013, 11:38:25 AM »

Hi, I have just set up my spindle in mach3. I must have wired it wrong or I'm misunderstanding something because when I enter a M5 command the spindle starts and when I enter a M3 it stops, which is backwards? I'm new to this as you can probably tell.
My set up is a breakout board HG08 connected to a Spindle VFD 2.2KW. I've connected two wires from the BOB relay to the DCM and FOR terminals on the VFD.
I have changed the DirLowActive settings and the StepLowAc settings in ports and pins>motor outputs through various combinations with no different results.
I have swapped the wires around that connect the relay to the VFD.
Clicking the button "Spindle CW F5" in Mach3 Program run does start and stop the spindle.
Also the spindle will run whether or not the EStop buttons are pressed or reset is pushed in Mach3, is this normal?
The VFD Manual says to set the control to PD001 "set by external terminals" which I think allows the spindle to be controlled by a relay, I have done this although I do wonder if it's a setting in the VFD rather than in Mach3 that is wrong.

Any advice gratefully received
Joz

Fixed! Faulty parallel port cable. I've swapped it and it's running ok now.
Thanks for your help.

Hi, I'm using the motherboards parallel port. I'll attach the xml file tomorrow (it's on work computer)
Thanks

If the Reset button is flashing, try toggling the Active low setting for the Estop. If it's not flashing, then your port address may be wrong.

Hi, the reset button isn't flashing. I have set the port address to 1, is this the correct address? If not, how would I find out what the correct address is?

General Mach Discussion / Newbie: Mach3 won't register input switches or turn steppers

« on: September 14, 2013, 04:50:11 AM »

Hi, wondering if you can help, I am new to CNC machining and Mach3.
I have wired up my CNC machine and started setting it up to run on Mach3.

The problem:
Mach3 will not register the limit switches or the E stop switches and the Stepper Motors will not turn.
If I hit an E stop or push a limit switch, the LED's in Mach3 on the diagnostics page do not light up. 


The hardware I am using: (all from CNC4YOU.co.uk)
HG07 break out board
CW5045 Stepper Motor Drivers
60BYGH401-03 stepper motors
Windows XP on a dedicated PC


What I have done to try and get it to work:
Checked all wiring, reinstalled Mach3, checked parallel port driver. The steppers are receiving a voltage, and the limit switches and the
E Stops are on a Normally Closed circuit, which breaks when I push a switch and test it with a multimeter.
I have run driver test= system excellent.
Under Ports and Pins:
Port set up is on port 1, 0x378
Motor outputs for X,Y & Z are set up on what I believe be the correct pins, DirLow Active is enabled
Input signals are set to port 1, each limit switch and E stop has the correct pin number entered, active low is enabled for each.


Can anyone help? It's probably something dead simple but I am at a loss to know what to do next.
Many thanks
Joz
