I tried mounting the head again and I don't think the nut is going in far enough. I think the nut has to move in about 80 thou. Right now the lock screw is sitting about 10 thou farther out than the...

The nut could be the problem. It looks like the turret will not move out far enough right now. When I tighten the nut it does not look like it will push the turret all the way onto the splines, it...

The new switches I ordered only supplied 6 volts instead of 24. I will have to add a pull-up resistor to make them work.

I still don't get why it will index at some positions and not others....

I think all the switches are working right now. But the clamp switch (X1006.3) only works when the machine is reset. Once the switch looses signal it will not activate again. The wires go back to a...

I ordered some switches I got some Omron TL-M2ME2 switches that seem to be a newer version of the original switches. They are obsolete as well, but there are still some new ones floating round ebay....

I could not get the B-phase signal to activate when rotating the turret. There are 2 sensors that are out of phase when the turret attempts to clamp. Which one is responsible for the signal?

The lathe has been working good for a bit with no accuracy issues. The other day it stopped indexing again. I think one of the proximity switches must be faulty. There are 5 switches from what I can...

The turret has the nut. Thanks for the clarification on the indexing. It looked like it was just hydraulic but it is nice to get conformation. It seems to be a little rougher on one side of the...

I have been adjusting the dogs in the back and it seems to be fixing the problem. Is there a specific way to adjust them or is it just a matter of fiddling with them until it works? Thanks for the...

I don't think the couplings are the problem because they were not taken off. They just had the taper pins removed. Does anyone know what the gap between the turret head and the base is supposed to be...

Do the dogs determine the turret index points or is that caused by a timer or belt and then the dogs and switches ensure that the turret is actually in the right position?

Do I just have to adjust the home position in parameters? I can get it to lock at most positions. Or is it a mechanical issue, I am not sure how the indexing works.

I just had the one small boring bar holder on it. I don't think the weight would be an issue. It looks like it is out quite a bit. The switch dogs would make sense, I will check that out. Is there a...

I was looking at it again today. The turret rotates a bit while it clamps at the other stations. Is that normal or is it in the wrong position but close enough to clamp?

I am having an issue with the turret. It is not clamping at 2 tool stations. The turret was taken off as the machine crashed. The turret was taken off and replaced and the tool stations that did not...

Playing around with the FIFO buffers on the computer did not seem to help so I found a DNC program that dripfeeds in 10 character chunks. That seemed to stop the drip feeding problem as it should...

Does anyone know the FIFO settings on the computer to use when drip feeding with a fanuc 10m Machine? I keep getting a buffer overflow on the mill. The DNC manual does not give recommendations.

I got the machine running today after playing around with the options parameters and correcting a few small mistakes with the cables. The wiring for the CD2 port is a hard to understand in the old...

I still have not been able to get it going yet although I have been busy with other projects. I am going to try changing some options parameters this week to try to get the options card working but...

I have finally managed to change parameter xxxx to enable RS232 A,B, and C (thanks to cncdiags comments on this thread http://www.cnczone.com/forums/fanuc/42320-fanuc-10m-11m-questions.html)

But...

Thanks for the information on changing the bad chips on the main board zavateandu. Fordav is right I am hoping to avoid messing with the main board. I still have not nailed down the necessary...

I finally got the card and I am still having trouble getting the rs232 to work. I am getting the SR 807 Parameter error if I set 0021 and 0022 to anything but 2 and a SR830 DR(2) off error when I set...

Thanks for the parameters Al! I will post again when I get the card installed.

Thanks, I figured that there should be no alarms using the no handshake null modem (4 and 5 jumped and 6,8,20 jumped). That's why I figure my connection on the main board is fried. I have also...

Yeah I was planning on doing that I just posted in case someone has already done this.

I have been trying to setup the RS232 port on a mill. I have confirmed cable connections are correct (I have used the null modem cable without handshake) and I am still getting a SR830 Error. I have...
