Overview Of The Process Of Building Your CNC Spindle Cable...

[@chrisgraves9601]

cant believe i just watched and enjoyed a half hour video about a spindle cable...lol. thanks for your attention to detail Vince. You put together an amazing system for me. Keep up the good work

Bought your cable kit and a HY connector from your ebay store built the cable and change it out for the cable that was on the vfd and there was a real noticable difference for me over the cheap vfd cable that came with my spindle Great product, thank you

Wanting to get your cable. So if I wanted to wire an E stop to remove the power to the Spindle... One way would be to relay remove the power from 220 volt or 110 volt supply. But could you use a 4 pole relay to remove the power to the actual spindle? Would that damage the Spindle or the VFD removing the load. How about leaving the VFD ON and then using the relay to start the spindle back up. Sort of like popping the clutch in a old truck... What are your thoughts?

[@corvetteguy50]

Digitalwoodshop, thank you for your support. I really appreciate it. The way you described killing the power will cause an immediate surge to the spindle as your switch would be wired to the spindle directly which would destroy the unit. The best safest way to kill power to the spindle is to utilize a power distribution bar, and kill it in the event of an emergency. This would be supplying your VFD power which in turn will kill the spindle. You can add a relay to the system to cycle on, an off the spindle through Mach3, but you can't utilize a relay to cycle the spindle on as you described. You must only utilize a switch that controls the VFD. Thank you, Vince

[@digitalwoodshop]

@@corvetteguy50 That is excellent advice.. Thank You.... That was my gut feeling that removing the load would make bad things happen.... Plus the EMI issues of putting a relay in the shielded line... I am working on 2 projects. One will be a 2.2 KW Water cooled Spindle for my little Shapeopo to cut Aluminum on it's 17 x 17 bed. Getting it used and will get a spindle for it. The other project is to get a air cooled spindle of unknown size to replace the cut motor in the hobby CarveWright CNC. The current cut motor has noise and brush issues. Would like to make a hush quiet spindle version replacing the cut motor. Would use the Cut Motor 115 VAC to operate a relay from the machine through the VFW if possible to turn on and off the Spindle. Thanks :)

The silicone ground drain is soldered to the O end and the other end is just in the shrink tube is this connect and what length is the drain wire

[@corvetteguy50]

The silicone drain lead wire is soldered to the drain lead from the cable. The bare shield drain is about 3/4in long that is soldered to the silicone drain wire. Thank you, Vince

[@thecommonsensefamilyincana3318]

Does cable to step motor also should be shielded? Then there will be a long list of cables that are used in a CNC, such as cables to limit switch, to step driver, to control board....etc.

[@corvetteguy50]

The Common Sense Family In Canada thank you for your support. All CNC robotics cables carrying signals for control should be at the very minimum shielded however double shielded cables are optimally used in best practice to mitigate both frequencies of EMI. You're correct they're a larger investment when integrating switches, and other accessories. Thank you, Vince

[@rrr92462]

What is the spindle connector called (the 4 pin)? Is that a Gx16 aviation plug?

[@corvetteguy50]

Thank you for your support. Its not a GX-16. Each one depending on the one you have will have a different diameter. Thank you, Vince

[@rrr92462]

@@corvetteguy50 Your ebay pages say "HY Large White Connector". I have a HY 2.2kW spindle.

[@corvetteguy50]

If the picture, and diameter matches yours from my listing then it would be correct. Thank you, Vince

[@joshuamartin2605]

What if the included spindle plug is too small to properly accommodate the cable's insulation?

[@corvetteguy50]

Joshua, Thank you for your support. Spindle plugs housings will all typically require machining with a Dremel tool to allow the plug to be terminated. Proceed slowly with a rotary file, and it's a straight forward process. Thank you, Vince

I've heard shielded cable is better grounded if its done at both ends (as long as both ends have the same ground potential). What are your thoughts?

[@corvetteguy50]

Hey Derek, Thank you for your support. I really appreciate it. Grounding a shield drain in best practice is to be done on one end of the cable to avoid the possibility of ground loops. Grounding both ends isn't recommended.Here's a great video on ground loops overview dealing with audio, but the principle is the same regardless of genre. kzbin.info/www/bejne/fYSQZ514oJ6Mhq8 Thank you, and please be safe. Have a great weekend! Vince

[@jimbmakin7975]

whenever I've wired control hardware professionally, especially when you're mixing different voltage levels, signals, high frequencies it's only connected at one end. Usually having the drain grounded in a star point at the controller (or inverter) side and either cut flush or shrink wrapped at the device or appliance side to prevent the possibility of a ground loop. The manufacturers of these controls always recommends it to be done this way

[@corvetteguy50]

[@jimbmakin7975]

@@corvetteguy50 thanks, you too! I just received and wired my spindle using the double shielded 16/4 from your ebay store.. Love that it's tinned copper too. Ended up using insulated fork crimps bent inward to better fit the huanyang terminals and also soldering them for testing until I get proper ring terminals.. question: do you recommend using ferrites on the spindle output of the vfd? if it comes to a point of having to strip more of the double shielded cable in order to be able to use ferrites, does having more exposed conductors outside of the shielding negate the benefits of having to strip more to use ferrites?

[@corvetteguy50]

@@jimbmakin7975 Thanks again for your support. You won't require ferrites on the cable as the double shielding provides the most EMI protection available, and considering the leads on the spindle cable are short run to your VFD they won't accomplish much. Thank you, and have a great weekend! Vince

[@204seven3]

Great work on the video, some terrific advice there I'm sure. One thing I'm not sure about, is why you chose the circle solder ends and not the forks. To me, the circle ends make sense when the cable is not accessible/exposed to being pulled, but I would think that the fork connection is safer when you have dangerous amount of electricity on the output side if the cable can be pulled such that it could break outside the case and be left live due to the circle connections not being released before a cable breaks. Whereas the spade/fork releasing just leaves a dead cable that isn't live with spade intact. Maybe the logic is the cable will never break, or it will break at the solder joint. I'm no expert, just opening the discussion on reasoning for one over the other so that any reader can understand the decision making. Now I'm going to google fork and circle connectors to find out whether my logic is sound or not.

[@corvetteguy50]

204Seven Pty Ltd thank you for your support. A solder type circle ring connector provides the most safety when dealing with terminal connections as if the screw in the terminal securing the connector ever comes loose it won't allow the ring terminal to simply fall out. Fork connectors can, and will simply fall out which could be catastrophic with a 3 phase output like a VFD. The connections on a VFD are not exposed when its terminal cover is secured in place. Thank you, Vince

[@204seven3]

@@corvetteguy50 Hello, Yeah I totally get that re: cable coming out that is live, but in that instance there, it wouldn't be live, as the source of power is the VFD motor controller which it's getting detached from. In that instance it seems safer to use the fork and the ring connector should be used on the input terminals to VFD. I'm new to this stuff, but that seems to make more sense to me. P.S I just bought both from a supplier a few mins ago, ring and fork [to solder and heat shrink].

[@corvetteguy50]

The cables end with the ring terminals gets attached to the VFD terminal block which utilizes a plastic cover which is screwed on Please review my video here at the 2:50 minute mark kzbin.info/www/bejne/hnfIaImcib2jbdE Also keep in mind neither a fork, or solder ring connectors are designed for tensile strength tests regarding pulling on the cables their attached to. This is where the end user must always execute common sense safety practices. If your assuming a fork connector will simply just pull out of the terminal block of the VFD when its pulled this is incorrect if the terminal block is tight, and being fork connectors are typically crimped, there far more at risk at failing a tensile pull mistake than a properly done (welded) soldered connection prepared with flux as they all should be. I'm glad you purchased the solder, and heat shrink as it will provide the best connections for this application. Thank you, Vince

Great video. Is 16 Gauge enough for a 2.2KW spindle?

[@corvetteguy50]

CR, thank you for your support. Yes 16/4 is fine for 2.2Kw. Thank you, Vince

[@Chris-bu6em]

So just to be clear, you either have to make sure your chassis is grounded properly or add a grounding wire to the 4th pin of the spindle motor. Do you have a diagram showing where to add the grounding wire in the spindle motor? Also the cable shield should always be grounded to the VFD? Love your videos btw. Thanks

[@corvetteguy50]

Hey Chris, thank you for your support. Please email me for the diagram of the spindle's 4th pin using a ground. Yes, the shield drain for the spindle's double shielded cable should be attached at the VFD's grounding terminal. Thank you, Vince

[@Mr8ohms]

My spindle's power ground pin is not contented to anything at all.

[@corvetteguy50]

MR80hms thank you for your support. Many ovesea spindles aren't grounded on the spindle's plug do to them believing you will be grounding the entire chassis itself which being a metal frame will by conduction ground the spindle as its also metal. If your spindle is lacking a ground on its terminal you can add one by removing its end cap, and soldering one on the 4th pin of its connector which doesn't have a lead attached. I have a diagram reflecting this if you would like to implement it, just message me .Either option is completely up to the end user to use, and each method works fine, but you must use one method to properly ground the unit. Thank you, Vince
