This is the story for you guys who thinks that safety features are not necessary. My pretty heavy and strong steel router went bananas the other day, all of a sudden the X-axis ran at full speed to the stop and it crunched everything that was in the new not-so-very-wanted path. I found out that the encoder line driver was damaged so I replaced it, just to see it happen once again when the machine was supposed to run a new program. I think that the servo controller card is defect and causes the line driver to over heat and fail. The setup I have for this machine lacks real software driven safety features, and I must trust the machines as I'm running programs for hours and can't babysit the workshop. So it all ended up with a new set of servo drives (and breakout) from cncdrive.com. I have been using their old Whale3 drives and they were really nice, and the new ones seems even better. The have both servo error signal, a charge pump circuit and a very nice servo PID setup/analyze software that connects with a USB cable.
If I already had been running these drives, my big alu work piece and the fasteners that held it would have been saved. Now, parked in the metal bin. Charge pump and servo error signal (I'll hook it up on the emergency input I think), why didn't I go for that before? ------------------------------------------------------------------------------ The demand for IT networking professionals continues to grow, and the demand for specialized networking skills is growing even more rapidly.
