Checked out your video Vince. Very informative and useful information that is clearly explained and demonstrated. I will be applying this grounding technique to my CNC router. Thanks very much.

I have only a small hobby CNC but I grounded it after watching one of your videos. Each axis is isolated from the others because of non-conductive guide wheels, so I had to ground each axis separately and the spindle. I don't know that it was necessary to ground a hobby CNC, but I wanted to do things right from the start.

quiglag, thank you for your support. Regardless of the CNC system's use the unit must be properly grounded for stability. I'm glad you took the time to do it right, and you brought up a very valuable point when diagnosing some systems that have components isolating axis. A full metal system will always be the easiest to ground. Thank you, Vince

great video as always . Just brought myself a 6040 (china) and have been going through your content , just gone through your soft limits one on mach3 all working sweet . looking to start upgrading all the wiring etc in the very near future ,just playing about with software at the moment. Anyway keep up the good work very much appreciated.

On my CNC I had not only to ground everything to everything else but also to install an optocoupler isolator board for the limit switches to work properly without EM interference. I guess some alien with a radio telescope from another planet across the galaxy can hear the EM noise from my chinese brushed spindle

Really helpful, I have a hobby CNC kit and discovered that the aluminium pieces are anodised which makes them non-conductive. Therefore, I have breaks between the stepper motors and the spindle, would you ground those components separately?
@corvetteguy504 жыл бұрын
James, Thank you for your support. Yes, I would ground each component individually till the entire system is under 3 Ohms. This can be tedious, but is well worth the time investment. In areas where there are coatings simply drill into them, and tap a small hole to mount a ring connector terminal for a ground lead, and you'll be all set. It will provide a very clean, and professional chassis this way. Thank you, Vince

I’d be willing to bet, bad grounding is the cause of 75%+ of DIY CNC issues. False limit triggers, unexpected ESTOPs, etc, etc. Equipotential bonding is your friend 💪

ApplesUPnorth thank you for your support. I actually feel insufficient grounding is the cause of at least 90% of the issues with DIY systems, including all the symptoms you listed. Thank you, Vince

Vince, recently purchased 2 Spindles from China (1 water-cooled, 1 air cooled). For some unknown reason Pin4 of the connector which is supposed to be GND is not connected to anything. So it was a matter of pulling the top cover of the spindle, soldering GND lead from the back of Pin4 to the frame of the spindle. All grounding issues solved. Point being what's the reason they don't connect GND to the frame of the spindle?
@corvetteguy503 жыл бұрын
Nova Star, thank you for your support. I really appreciate it. The reason a spindle isn't grounded overseas is the manufacturers assume the end user will be grounding their CNC chassis as they should all be anyway, and in doing so will ground the spindle if the chassis is metal which makes it conductive. Either method works, and its really up to the end users preference. Thank you, Vince

Another good video. So you would be checking the earth ground ohms at each components drain wire and looking for less than 5. If you are over 5 install additional wire from the component to the chassis? To reduce ohms. And in saying that, use you volt meter to determine whether you are better off using the drain wire at the component or at control module? Cheers again
@corvetteguy503 жыл бұрын
Yes 5 Ohms is still high. I prefer three or under. You're correct the more leads you install the lower the Ohms you'll achieve. Grounding can be done at either location, but I prefer the electronics chassis. Keep in mind the CNC chassis must be grounded as well. Thank you, Vince
