Hi,
I'm just getting my new Tormach set up. It is on the deluxe stand and connected to power. I don't have the computer yet, but according to the book the spindle should turn in manual mode.
When I hit the spindle start toggle switch I hear what sounds like a relay click and a fan running but no spindle turning. I have tried the speed control knob in various positions. The Machine power light is not illuminated either.
my computer is connected via parallel but not on:Main Power on, e-stop out, press green button, spindle lockout key clockwise, spindle in manual mode, press spindle start and it works. I don't know if having the parallel cable plugged in makes a difference.
The spindle drive door is tightly latched and the lockout key switch is on. The main power switch on the right side of the box is on, the Auto/Manual rocker is on manual, the E-Stop knob is released and the green power button is pressed. The spindle start rocker still has no effect.
However, I guess it's pointless to try to run the machine without computer control so I will wait until the computer arrives.
i had what sounds like the same problem. the vfd was changed out twice before it was fixed. i'd give tormach a call and see if they can help trouble-shoot it so you have it running when you do get your computer. they are very helpful.
Tormach's technical department helped me work through the problem. They even sent me a replacement control board to try. It turned out there was a cable inside the cabinet that was not connected.
WOW- What you are saying is that nobody even test ran the spindle before shipping the machine. Sending out a control board first sounds like the diagnostic skills you would find at some car dealership.
I was impressed by Tormach's willingness to help me solve this. I always received a reply quickly to my e-mails.
The first thing that I was told to do was to check for loose connections. I guess the hanging ribbon cable was too obvious. Due to my ignorance I just assumed it was for future expansion to the 4th axis or something. I didn't even notice the empty connector on the inside of the door.
Mazak,
Did sound a bit harsh I guess- when he said the cable was not connected I concluded that it meant "never connected", and therefore would have been discovered during a test. A better choice of words would have been " it came loose" . It also sounded like they just shipped off a new board without going through the basics of checking the connections, but apparently they did that and the owner just failed to see the obvious.
