After reading all the nice comments about the Grit Automation on the previous topic, I wish to take this route with my CF741. However, being a combination machine, I was wondering if anyone had installed Grit with the CF741. For instance, I guess it is easy to detect the the power is on using the toroid on the main power cable, but how do you detect which of the 3 motor is actually on?
You will need to put a current sensing coil on one lead of all of the motors (only three I think).
I saw that Felder resells a device from Ziehl that detects current running through 1-8 machines (link at ) - I guess that this would be useless using Grit automation devices/sensors?
That is an alternative (and possibly cheaper, and less feature rich approach. Still needs the current sensing coils though.
Finally, one last issue, my dust collector is a Harvey GyroAir 700. I usually leave the machine powered on and use the remote to start/stop it. Just powering up the machine won't turn the extractor on, you need to press a button or use the remote. Anyone has used the G700 with some form of automation? The larger models G800 and G1000 can come equipped with automated remote circuit, but they cost a lot more, and are quite a bit larger for my hobby shop. I could have gone with the RL140, but again, over twice the price of the G700. I like the G700, but when I do serious planing, the small capacity and the fact that it stops with an alarm way before it fills up the bags makes me stop working, open the dust container, reshuffle the chips and start again. Lots of handling, but again, just a hobby shop. I can't see any production shop using the G700 except for a table saw or a CNC...
It is best to direct your questions to the GRIT team. From what I have read here they seem to provide excellent support and should be capable of answering your questions most likely.
Kind regards,
