6610 run amuck

[eforer]

Hi Guys,

Multicam installed a used 6610 in my shop last week. I finally had some time today to work with it after getting my HSMXpress postprocessor working correctly. I think I have some sort of a communication problem. sporadically programs run without a hitch, but at completely random times during programs I will get "out of bounds" errors with all over the map numbers. It occurs on all axis, in positive and negative numbers and values as small as .5 to 2000.

I've run the same program multiple times from the same home position, it will work one time and fail at arbitrary points (most often in the beginning) other times. The errors are inconsistent and I've never seen the same values come up.

I've also had issue with it "skipping" instructions. IE it will run the program but not execute a "Z" move. Again, sometimes the program will run flawlessly, but other times, even running the same program back to back it will randomly have issues like described above.

The machine is running off an old PC running windows 2k, it was supplied by multicam and was equipped with winDNC95. The serial cable looks pretty ratty and at the machine end, it has no insulation or strain releif and the jack is sort of floating in the box. I'm frustrated by the condition of these features as the machine was purchased as being fully sorted and gone through by Multicam east and professionally installed. Any thoughts on possible solutions would be greatly appreciated!

Question while the install was taking place...did you have chance to run any programs while the tech was onsite...and if so...those programs...what CAD/CAM software were the programs generated?

Hi,

He ran a simple square program with the spindle in the air, nothing in material. I have had the issues I've described with my own programs made in solid works with HSMXpress for CAM/Post and the files supplied with the machine made in enroute. The problems are more frequent in the longer, more complex programs and those with curves/ramps, but they do occur in even the simple square program supplied with the DNC computer. They just had us adjust the power supply voltage to the main board, but the problems persist. I am so frustrated, we have a lot of parts that need to be cut.

You could be having a power issue but it could be that your power supply is fluctuating and not holding the correct voltage, you could have a bad power supply. Make sure the multimeter that you have can read two decimal places ie: 8.09 vs showing just 8.0 or 8.1, you need to take measurement where the power is going into the control board, it should not vary more the .1 higher or lower. If you are having a wild swing your power supply needs to be replaced,
.
Also check to make sure your plug going into the control board is staying seated correctly, if you wiggle the wires going into the plug check to make sure that the board doesn't wink out or reboot itself.
