I have a 6T that the control is not working. Monitor screen is blank. When you turn it off after being on the monitor does blip a little green light which indicates it has power. The motherboard...

I have a 6T that has been running all week. Over the last few days, I have been hearing the pump cut out for a split second and keep going. Today the machine finished a part and then the hydraulics...

I checked all the above and have not found anything.
I was wondering how much of a project it would be to convert this machine to an AC spindle? I have another machine with a 6T control on it with...

The drive unit is A06B 6041 H105
The PCB is A20B 0008 0375/02

Thanks, that gives me some stuff to check. I will keep you posted.

The motor brushes looked very good. This was a low mileage machine that came out of a school.
I talked to TIE today and they will only do an exchange on my board. $4754.00 if mine is is...

Anyone have any recommendations on where to send a board to get checked/repaired? I would like to send out my spindle pcb to get checked by someone trustworthy...

The M41 did not change anything.
I just checked the overload on the spindle contactor and it is ok.
I checked the thermal switch on the DC motor and it is ok.
The spindle will not do anything...

Yes the machine lock was on. Now I can jog the machine, home it, and enter other commands via the mdi. I cannot get the spindle to turn on. I can enter S500 and a M3 command and only the op stop...

I just acquired a Pratt Whitney lathe with a 6T control on it. When I power it up the Machine alarm is lit on the operators panel. The operating manual says this is a problem on the machine side. ...

I just purchased a machine and when I got it home I thought to call the previous owner and ask him what he used for way oil in the lube system. He responded that he used a 10-30 motor oil. Years...

Very nice. :)

I have 3 Bridgeports all retrofitted wth new electronics and running on Mach 3. I an now looking at getting rid of the noisy/clumsy vari-drives and going with a VFD. Probably going to go with a...

Working on a DIY vibratory polisher. After reading many threads and posts I think I have a design for my unit. The only remaining question for me is what to use for a lining for the tank? My tank...

I need to rotate an engraving file so I can engrave lexan from the back side. G68 rotates in the XY axis only. How can I rotate in XZ or YZ axis? Thanks

Plus you can drive 2 servos with one drive in DualDC mode.

I have a Series II that I retrofitted last year. I used a PMDX132 and Gecko 203V drives. The 70VDC power supply is from Keling. I used the original Bridgeport steppers and they work great. No...

I have 2 XE-160's running in DualDC with a VSDEPI breakout board. The problem I have is that during a cut it will stop with Mach 3 saying it is a External E-Stop Requested. It will not let me reset...

So I guess what you are saying Al is that the max voltage is not crucial if max RPM is not a necessity?

I don't really need the extra RPM. I am just concerned about performance loss being 18% under rated voltage.

I am doing a Boss 8 servo retrofit using the original 3 phase T2 transformer on 208V. All I can seem to get is 80VAC on the secondary side which after rectification gives me about 115VDC under...

Al was dead-on about the flyback diode. A diode on the DC side fixed it right up. I did find out that there was a oem Bridgeport snubber on the AC side. The machine starts the spindle and then...

It has a oem Bridgeport capacitor on the AC side but nothing on the DC side. I will work on it tomorrow. Thanks Al.

New build using two xe-160's in dualDC mode and a vsdepi breakout board. The problem I am having is that everytime I use the onboard relay to start the spindle, it trips the emergency stop. I have...

I would just go ahead and build your system using the Bridgeports and see how they do. Then at a later date you could replace them with the Kelings if need be. You won't be out anything but you...

I agree with DrStein99. I retrofitted two Bridgeport machines. Both with Gecko 203V's with a PMDX132 BOB. One machine I installed Keling steppers and one machine I left the original Bridgeport...

I have a machine that runs 3 203V's with a PMDX132 BOB. The problem is that the Y axis occasionally faults(red led's come on) in the middle of a run. Ruined parts because the machine keeps going...

Thanks George. I had problems with inconsistent Z depths although the counter always indicated everything was where it was supposed to be. I regulated the air and the Z depths are correct and the...

You don't have to pull the transistors to check them. I used my Flukemeter to check the transistors in place(diode function I think). Check it across the terminals and read the number and then...

Yes, I have had those diodes go bad. I used to check the diodes every time I replaced the transistors. I don't remember if you can check the diodes in place or not.

Keep us posted.
