simple concept, powerful notion. unfortunately i don't have a product with verified manufacturer, but a kit CNC. oh well, no manufacturer spec grounding option. but i studied this video and i just grounded my chassis, using the resistance method (not contact beeping) to validating low resistance ground path between controller and chassis at 6 ohms-previously was at 30 ohms, so definitely improved the situtation using your tips.
Great job, unfortunately as I stated in the video for robotics use your chassis should measure a resistance of 3 Ohms, or under to be considered grounded.
Add some more ground straps to the chassis. and you should drop the resistance.
Thank you,
Vince
Great video! Could I use a propane torch, or a mini butane torch, for soldering the ground strap terminal? Also, do you have a link for purchasing just the ground strap cable itself, and perhaps the terminals you use?
Thank you for your support. Either torch will work. Please email me from the video description to purchase the strap, and connector package you need as I will need to know the total length you require. Thank you,
Vince
Thank you learning form other mistakes
Thank you as always for your support. Vince
every genre has negative things could you list cnc negative things thanks
Thank you for your support. Please be more specific? Thank you,

@@corvetteguy50 someone wants to start a cnc business needs to know postive issues and negative i want to know negative issues
I understand now, Ok I'll cover some details on it. Thank you,

Closed loop steppers exist and servo drives that operate on step pulses also are a thing we don't know what equipment he has so commenting he is wrong.
Thank you for your support.
A closed loop motor is a servo as it tracks the motor's shaft position.
Here's some detailed proof on stepper" open loop" differences, and "closed loop" servos.

Steppers don't use encoders?
Thank you for your support. No sir, they're open loop motors. Servos use encoders. Thank you,
Vince
@@corvetteguy50 there are closed loop steppers with enconders, they are actually very popular.
If a motor has an encoder that registers its motor's shaft position its a servo regardless of what other vendors call it.

Thank you,
Vince
@@corvetteguy50 no that is not true. Closed loop steppers and servos are very different in the way they are internally built. You can't just slap an encoder to a stepper and call it a servo. There is much more to it, like very different coil windings. That is even shown in the link you posted.
Thank you for your comment.
A servo, is a motor that use an encoder is to provide feedback of the motors shaft position to detect inaccurate positioning.
Direct from AI Google search I listed below.
Stepper motors don't necessarily need encoders, but they can improve their accuracy and performance.
Encoders are rotary devices that provide feedback on the motor's speed and position, which can help the motor:
Traits of a stepper with added encoder are:
Avoid errors: Encoders can help the motor avoid out-of-step issues and lost steps.
Improve reliability: Encoders can help improve the reliability and safety of the system.
Detect faults: Encoders can help detect abnormal conditions and faults in the motor
You realize the above listed traits of the stepper with an encoder are that literally of a servo motor correct?
This is the most asked concern of a stepper regarding missed steps is its "open loop" accuracy.
Speed, and performance of any motor can easily be modified by the transmission used for the persons application regardless of the motor type selected.
If you want to discuss the semantics of the internals of the motor then that might mean something to you, but for real world CNC applications in over 4k sale transactions I've completed I haven't had a single client ask about the internals of a how any motor is built.
Do you know why??
No one cares if it works for their application except a random person leaving a comment on UA-cam with a Nebula video from 8 years ago.
Thank you,
Vince
I love how he explains how to do a continuity test but doesn't know what it's called and doesn't look at the measurement. He could have 40 ohms, higher than most heater elements and still beep.
Thank you for your support. Details are really everything with these systems. Thank you,

What's the best largest cnc router brand for under $8k? I was looking at altmill but their lead time is ridiculous. I don't feel the xcarve pro is worth what they want for it either. Is it a good idea to build my own or are these systems good? Avid is out of my budget unfortunately
Altmill is decent and it comes with close loop steppers 😅 onefinity elite it's okaysh also comes with closed loop steppers 😂 cnc4newbie looks good value.
Really looking for 4x8 @@JDMeister
Thank you for your support.
I would need to know some details to answer this question, as your applications with it play as much a role on choice as your budget does. Please contact me to schedule a consultation.
Thank you,

To complicate things even more, there are power distribution panels in older homes with a bonded neutral/ground. A potential new can of worms.
Thank you for your support, and very good point. Vince
Using the diode test feature of a meter is not the correct way to check continuity.
youtube will censor this comment, but if you do get to read it, wouldn't grounding your robot in the electrical cabinet create a ground loop? don't you want to disapate the emi through like a grounding rod? and stepper don't have encoders from the factory. but you can add encoders to make a closed loop system. im sure thats what this guy did and knew exactly what he was talking about. its you and everyone else thats messed up, not him. (hyperbole)
Thank you for taking the time to post your comment.
Lets look at what you typed out.
Wouldn't grounding your robot in the electrical cabinet create a ground loop?
A ground loop isn't possible if he's using the same source to ground the chassis ( this means for example his , breaker box/ground rod wall outlet and CNC enclosure's ground bus as they would all be on the same grounds in best practice regardless of their location to his chassis) EMI dissipation is accomplished through connecting "shield drains" from your double shielded cable to a dedicated ground bus which is using any of the ground sources discussed above.
Most controllers use the ground bus within their electronics enclosure for motor cables while VFD's will use their integrated ground terminal that's grounded to your wall outlet upon plugging in its power cable.
CNC chassis can certainly use a ground rod if resistance is high, or for applications like plasma systems where EMI is produced in large quantities. The goal overall is the resistance rating to produce stability as the faster EMI gets dissipated to ground then that energy can't corrupt our precious control signals.
Stepper don't have encoders from the factory. but you can add encoders to make a closed loop system. Yea, and no where in the video did he state this? I don't make assumptions. He used incorrect terms regarding his motors in the video, and that's what I corrected.
Thank you, I hope this helped clear things up.
