What an awesome man you are. I thank you from the bottom of my heart for your information, not alot of people are Willing to share the knowledge with everyone else. Do you still have the pdf? I would like to a copy if possible, since i like reading rather than watching all 4 yt videos again.
Thank you for your support. I really appreciate it. Please contact me through my email address listed in the description for a free copy of it. Thank you, and please be safe. Vince
Thank you for your video, I have learnt the hard way being a novice how much grief EMI can give me with my cnc controller. I initially had to re build from scratch my 6040 controller and couldn't fit it in the new parts into the metal box supplied nor could I afford an extra £70 for a another at the time so built a wooden box and attempted to shield everything by linking them to the emi filter that was grounded by the main plug. I still had problems and was fault finding where the interference was coming from and affecting what, I found this to be the cable i had shielded from the X driver to the motor was interfering with my Y driver cable however simply moving the cable and hearing the motors judder have now discovered I killed possibly all 3 drivers and or the beak out board (this supprised me as i am still unsure how this occurred by simply moving the cable and not touching anything else, also correctly wired) is this something that can happen or make sense to yourself as i was a bit dumb founded when this occurred?
Hey Graham, thank you for your support I really appreciate it. EMI is one of the most difficult issues with the CNC genre as its an unseen force, which makes it super difficult to beat. The issue you may have encountered when you moved the cable is a possible discharge from static that passed to the drives. The discharge can easily pass to multiple drives if their wired together by way of "Daisy Chaining". Whenever your handling the drives is best to use a static discharge bracelet just to be safe. I'm sorry you've had such issues with the 6040. I would make one suggestion an that would be to move the electronics over to a metal enclosure from the wood as it will act as a Faraday cage to protect the electronics from EMI, and allow you to ground it for proper EMI dissipation. It will also eliminate the fire hazard. Thank you, Vince
@@corvetteguy50 Hi thanks for the quick reply, it makes sense now that you mentioned the static discharge as at the time i was attempting to separate the cables from each other as outside the box they were rapped together with a "plastic tidy rap thing" so when i killed my machine i was staring at it thinking "how?" i have purchased a electronics project box from ebay which is arriving tomorrow, its design is plastic with a metal mounting on the back (base) which i intend to ground everything to it. my next question is as i only have the metal sheet as a mounting panel is this enough to create a faraday shield for the parts or would i have needed all front side and rear covered in metal? ps you can see my horrible attempt at cnc from my page if you want to cringe.
You would require a metal enclosure with metal on all sides for the unit to act as a Faraday cage. Don't be hard on yourself as CNC is a large elephant to eat. Thank you, Vince
my neutral to earth gives approx 30V which is high , and the authorities are not willing to fix it since months, is this going to be an issue? Is there anything i can do?
Hey man! Thank you for all the great content u provide! I am putting together the electronics for my 6040 cnc at the moment. I have no experience in electronics. I have bought some shielded cables and connected them with the 4 unshielded cables from the nema 23 stepper motors, simply soldered them to the wires in the shielded cable, wrapped some of the shielding around and covered it with some shrink hoose. Most people seems to do like that, however I have to admit that it does not feel optimal. But i dont know. I would like to solder the wires from the shielded cable directly to the motor. Do you know if that is possible on nema 23? If they are easy to open up for some soldering? I have not looked into that. And would there be any win to do that from your perspective?
Hey Chip thank you for your support. Shielded cable only is effective if its ground drain lead is grounded. Here's a demonstration ua-cam.com/video/eQF7okWWWfQ/v-deo.html Here's my overview on shielded cable.ua-cam.com/video/84udcsEC7zI/v-deo.html Thank you, Vince
Thanks for putting that out there. Great stuff! Very much appreciated.
You bet...:) I'm glad to help. Thank you for your support. Vince
