Just came across your channel! Very excited to see the content you focus on! Thank you for your work! God bless you I subscribed as soon as I saw all your videos 😊

Amazing how compact it can be with the drives being in the motors.

[@SuperYellowsubmarin]

Yes, that's why I love my Clearpaths. Only downside, only one feedback line :(

[@polaraligned1]

@@SuperYellowsubmarin Not sure I understand what you mean about "only one feedback line".

[@Autonomation365]

@@polaraligned1 I assume that he means there is only a single output from the clearpath motors that indicate motor state, the HLFB output. No encoder output, nothing that provides more k formative motor state information without jumping to a USB cable and the MSP software.

[@SuperYellowsubmarin]

@@polaraligned1 feedback line (HLFB as Technik names it) is the only output of the SDSK version of Clearpath servos. You can assign only one of several possibities (on position, fault, encoder index, ...). Sadly on CNC you absolutely need the fault output, so you cannot use other fonctions at the same time like encoder index for accurate homing, like you would on DMM.

[@polaraligned1]

@@SuperYellowsubmarin I see what you meant now. Yeah, that does stink.

Hi Marty! Thanks for taking the time to create the video series. Great information and just in time for my build. Couple of questions, What do you use for bringing the power into the panel? Disconnect switch? Thanks, Jerry

[@martyscncgarage5275]

ABB on/off switch. I will feature it in the next video. You should go visit my build page on the Centroid forum so you can get a link to my Google album to see random pics. centroidcncforum.com/viewtopic.php?f=60&t=5389

Is there a polarity to the Snubber? how do you have it connected to the contactor? thanks Marty for everything that you do.

Nope

Hi Marty, do you mind explaining whats going on at the terminal blocks? I have never used them before but want to avoid using multiple outlets and have breakers like you have here. Are you using the yellow ones to get power from the meanwell and then supplying to power hub4? Also I am planning to build a router, would this arragement work? Lastly, how is the IPC5 being powered? I noticed in the beginning you said you had breakers for VFD and Control but I m not sure what you said about IPC5.

[@martyscncgarage5275]

I no longer have that machine. What are you wanting to know? Terminal blocks are just a convenient way to land your wires. Suggest you follow a Centroid Acorn System schematic provided by Centroid on their Web site as a starting point

Hi Marty , Can you explain how and where the t suppressor plugs into and what brand it was and how to buy one

[@martyscncgarage5275]

The quench arc? It goes across the coil on the Estop contactor. Centroid sells them.

[@janvirbrar4181]

How did you connect the E-Stop switch, C86ACCP, and the contactor together? I cant quite clearly see your connections in the video. I've seen acorn e-stop schematic and c86accp schematic but I cant seem to figure out how to put them together.

[@martyscncgarage5275]

Use another set of contacts on the Estop contactor to enable C86ACCP (going from memory, that was a LONG time ago and I have since sold that machine)

[@janvirbrar4181]

@@martyscncgarage5275 Can you use a 120V contactor in the layout that you have? Or would that not work with Acorn's relay board

[@martyscncgarage5275]

@@janvirbrar4181 I would not recommend it, but it would work. I'd suggest 24vdc

[@tstanley01]

You said you wired your E stop inline with relay 1 and input 8. Is the reason you ran it in series with relay 1 (no fault) is incase acorn freezes up and doesn't respond and you need to physically disconnect the contactor? I just wired mine to input 8 and it seems to be working fine, but I should probably change it if that is the reason you did it that way. It makes sense to have a physical disconnect.

[@andrewnash48]

Hey Marty, I am just getting around to wiring my back panel. I have the C86ACCP and somewhere else you showed driving the NO_FAULT terminal on the C86 using OUT1 from the relay baord, but that is now driving the coil for the contactor. In the configuration shown here, what is being used to drive the No_FAULT to enable the C86 - it looks like there may be a couple of purple wire shown but I could not figure out what they went to.

[@martyscncgarage5275]

You need a spare set of contacts on your contactor or fir another relay oof out 1

[@andrewnash48]

@@martyscncgarage5275 thanks - I was tending toward setting up another relay, but the extra set of contacts on the contactor is way more sensible

[@hamiltonpianos]

As the series continues, I'm feeling more and more out of my depth...! :( That said, I had the same feeling building my first CNC using Arduino and UGS, and that turned out fine. Very close to ordering my Acorn, so looking forward to the next exciting instalment of the SYL X4 Mill series! :)

[@martyscncgarage5275]

You have a basic understanding of CNC control, some basic Electrical/Electronics experience, and when you get stuck, the Centroid CNC Users forum is there to help

[@jamesmaccubbin7434]

Marty - thank you again for these videos.Tthe way you have it set up here, you only have one 220v coming in, and are powering both the spindle/VFD and the IPC-5 power supplies for the Teknic from that one power cable. I assume that means that the IPC-5 can handle 220v, and the Meanwell power supplies can as well. Is that correct? I love the simplicity of having one cable in and not a seperate 110v cable. I didn't realize that was possible until this video. Thank you!

[@MartyEscarcega]

Yes, as I explain in the series, by removing a jumper on the IPC-5 power cable it accepts 220vac as do the power supplies in the cabinet

[@oswaldomoraleslopez]

Un gran video.

[@andrewnash48]

Thanks for the content Marty. The Centroid wiring diagrams for the C86ACCP show an E-stop with a single NC connection - your setup looks more sophisticated. Are there downsides to the version shown in their schematic? I dont have the VFD that you are implementing was I am using the integrated version on the PM 728VT

[@martyscncgarage5275]

I always suggest using an Estop contactor. That is the purpose for the second contact block.

[@andrewnash48]

@@martyscncgarage5275 I am assuming that the contactors value is primarily for higher current applications? Or does it give you an extra estop option?

Pg 36 of ClearPath User Manual, Switching and fusing section (in regard to the IPC-5) says: "Switching the DC output side, especially with inexpensive relays, will ultimately result in poor performance (drop outs) due to pitting, corrosion and contact welding. If a power switch is required, install it such that the supply is disconnected from the AC input side." Obviously you're using a fairly substantial contactor, rather than just a cheap relay. But, their second sentence may not ONLY be in reference to the first sentence. In other words, there may be other reasons (than pitting your contacts) why you should switch the power from the AC side rather than the DC side. It sounds like a "shall" statement rather than a "should" statement. I've been in automation since 89' and I've never burnt up a component, which is a very rare claim. The reason is, I read and reread everything and I leave nothing to chance. This particular warning caught my eye because I've seen power supplies that will spike themselves to death if you disconnect the DC side. I was helping a company out who was smoking DC supplies, one after another. I put a high impedance meter on the DC and saw it go from say 24VDC to almost 100VDC, just as they removed the load (switched the DC off). 2 or 3 times and the supply gave up the ghost. I downloaded the manual and showed them where the mfg said only to switch the AC side. After the wiring change, they had no more issues. The IPC-5 may be completely different, but their statement reminded me of this interesting issue and I wanted to share.

[@martyscncgarage5275]

They prefer you to kill the AC. I changed it before I sold the machine

[@cornpop7805]

Cool! I extensively rewrote my comment (very long) and posted it. I then saw your short and perfect reply. By the way, nice job on the system and the video. Thanks for all that you do!
