- A bulkhead connector is made, to deliver main power safer, without exposed terminals. Starting with a Tripp Lite extension, the IEC C13 C14 connectors are scanned and parts designed for CNC machining. The bulkhead connector is installed into Misumi steel clad foam panels and installed in Confluence R&D's plant imaging and phenotyping machine. Power cables with IEC C13 and C14 connectors are commonly used electronics.

Used this for my DIY 2.1 speaker
Nice project Kent, turned out really clean. Wish the Tormach had servos.
+Craig's Machine Shop Thank you Craig. I learned of Leadshine during a visit to Tormach. Perhaps Tormach could switch to the equivalent closed loop stepper motors with minimal changes? I wish my spindle motor drive had even half the capabilities of the Tormach VFD.
I think some have modified their Tormachs but I don't want to loose tech support doing something like that. I guess I should be content with the power I have. A big step up from the mini mill I came from.
+Craig's Machine Shop If I had a Tormach I'd be hesitant to modify it unless there is a quantifiable reason and improvement. The guy who started Tormach is unfortunately no longer alive but he was very sharp. This shows in the quality of technical documentation Tormach supplies. The only reason I can see to swap for servos is for constant torque at high feed rates... 100ipm is already more than what I need :) My experiments were to demonstrate that people putting 800 oz-in steppers on their pm25s just in case of lost steps just don't need to, but then again the open loop steppers are inexpensive, so no harm :) My only criticism of Tormach's motor selection is that from the same manufacturer they could have sourced closed loop stepper motors for roughly $200 total on the BOM at volume and dominated the space even more with that much better of a product. Just my opinion from a technical angle
Wow, not much more for servos. Well, if Sky Fire starts getting popular maybe they will change to servos.
You can get every imaginable variation of that type of connector at Digi-Key. Literally thousands of variation. Excellent effort nonetheless.
Thanks Jason. If you can point me to one please do. Using Digi-Key's parametric search over the power entry connector section, setting connector style to IEC C14 returns a lot of results. Looking at termination style, "wire" is probably the closest, (terminal, spring, etc. are not.) but that returns pigtails. Maybe they could be soldered to a longer cable, installed into conduit, or something. I'm not sure what would be needed. It's probably out there, but I could not find one like what I made, with a sound cable on the "inside" where for someone to touch mains they would have to be very determined. Hope that makes sense. Not saying they don't existing, I may have been searching for the wrong thing. Now I understand why where I used to work they would use the McMaster style, and wrap them with black tape. That's not going to fly now though :) Take care
I guess I skipped right over the exposed terminal point. That certainly cuts your options. There appear to be boots available for some of the ones with exposed terminals on the back. Those might be easier but would not be as good as what you've done.
@@kentvanderveldenDataPro do a 'Panel Mount C14 to C13 AC Power Cable' (e.g. 9291-01C) that I'm guessing achieves what you want. Unfortunately for me, it's only rated to 125V. Great video.
@@alexb1792 That should work perfectly! I could not find anything like this originally. Thank you!

First video of 2018! DIY CNC equipment being used to create a part where no commercial alternative could be found. For that satisfaction, we put in the hours doing the conversions.
I have g0704 and was bummed by lack of spindle power. I installed 1.8kw Nema 44 servo and now I am so happy. Much better then dc motor(and I have tried treadmill motors).
Now I am thinking to upgrade my mach3 to LinuxCNC to get rigid taping...
Hi Darko, I have a servo on the way for a new spindle motor, although only 750W but a decent 1:1 top end speed. I've been working with rigid tapping with an encoder on the spindle. If you have encoder output from your servo drive perhaps you could use that instead of a separate encoder? At least that's what I'm going to try. Mounting and removing the encoder to change tools is not ideal.
Which servo did you use? I ordered one from DMM with a holding brake and a Dyn4 drive. Had hope that the servo brake would be enough for a spindle lock, but that's not going to work :)
I got china made 1.8kw AC Servo 3000 RPM with driver of ebay. It costed me about 400$ or so. Driver is not greatest(double the price for brand names or even triple). Driver has position/speed/torque mode and separate encoder output. Also supports modbus protocol so it can be integrated well. There are even stronger servos but they are NEMA52 size nema44 fits flush with G0704 head. It requires pulses of 500kHz frequency. I have some MAch3 card that is good enough to generate pulses but Mach has limited support for this. I want to get into LinuxCNC for advanced features that are possible with servo spindle but was wondering about hardware. Would you recommend MESA Ethernet boards for LinuxCNC? Thanks
Oh, I probably looked at the same servo combination. It seemed a great deal, but unfortunately, I don't have 220VAC readily available. Please see the link below for the supported hardware on LinuxCNC. I started with Mach3 years ago and at that time people disregarded Ethernet or USB because of latency. However, I bet the modern Ethernet and USB solutions don't send pulses over the link, instead receive velocity information from LinuxCNC and then the board generates the pulses, so a much denser information, and send "virtual encoder" feedback to the LinuxCNC to close the loop. The only experience I have with the MESA products is the complexity in selecting the proper board from their website. I ultimately went with the Pico Systems Universal Stepper Controller, which is parallel port based, receives velocity information, and can take encoder feedback for four axes. I considered MESA again for my lathe, but ultimately went with what I know, so I could keep the mill and lathe configurations similar. If there are no problems with latency or whatever else, it sure would be nice to have a clean Ethernet based board. Sorry to not be any great help in this area. If you get the MESA card, I would like to hear how it works.

Been reading about the 7i76e, and it's pretty nice. I found this thread, and the second message from poster PCW clears up a lot. This board would save a lot of space and headaches.

Where can i buy something like this on a uk based website or that can be shipped to the uk?
Someone pointed out a commercial one for the US plug in the comments. Maybe the same site will have UK plugs. Sorry, that's the best I know.
@@kentvandervelden I don't seem to see that comment
@@makershub7007 It's Jason Carter's. Here's the link

Sinolec sell an IEC C14 to C13 Panel Converter (i.e. without the wire) - CWE-1314. Also DataPro in US now supply a 250V version of their Panel Mount C14 to C13 AC Power Cable (minimum order value of $200 though).
Are you able to share the CAD file?
Send me an email, and include format you'd prefer, and I'll find the files. If your panel thickness is much different, you'll need to change one dimension, no problem. If using a different brand of cable, you may need to change more.
Hello Kent, what are your thoughts on using single-board computers in applications like this? Have you considered using Raspberry Pi or LattePanda instead of panel computer and PLC? LattePanda besides being a PC, has Atmel micro-controller onboard, that works independently and can control GPIO and take care of real-time tasks, while computer runs high-level software. It has display and touchscreen too and is much cheaper. Does this application really need industrial-grade hardware?
Thank you Artem. I'll read about the LattePanda. Some decisions were made because of the time available, and others because I wanted to learn, and others for future support by others. When this one is complete optimizations will be important and please send me any suggestions you might have.
I need a reasonably decent computer for the image collection and analysis. I think the panel PC has four hardware threads, which I use all of to process the images in parallel, and I barely get them done before the next tray of plants is loaded. I wanted a nice touch monitor. On the last instrument I used a Dell touch screen. That worked OK, but required some tweaking to mount, and then there's the cable management. So, I went the Cadillac route and got the panel PC. Was it a good choice? Probably, because of the convenience, but the GPIO and PoE features did not work for a variety of reasons. Next instrument will probably use the same touch panel, but a different PC, without the fancy GPIO or PoE stuff. Still needs to be a fairly recent CPU though.
Some of the decisions I made in this project were to avoid using a PLC, because I didn't know ladder logic. In the end, after the panel PC GPIO failure, I got a PLC and spent a few days learning it. I'm converted onto using PLCs for these applications because of the certainty and stability. For example, the panel PC has glitches, such on power up, that could be unsafe in other applications.
There's a motor controller for a couple of motors to move a camera from Anaheim Automation. I've shown it on Instagram only. I'll likely eliminate it and do motor control from the PLC as well. While the AA controller is nice, only power and USB is required, it's not very reliable, and relaying messages between the PLC and motor controller via the PC adds complexity to the main software.
Any suggestions are welcome. I need to optimize along a few different dimensions: cost, time (development and assembly), ability to have others assemble and maintain, etc. So, creative solutions could have a large impact.
I hope your New Year is off to a great start!
+Artem Anchugov Hi Artem, were you thinking the current LattePanda or the LattePanda Alpha 864 on Kickstarter? I had someone ask about LattePanda for something else two days after you suggested it. I live under a rock so had never heard of it. Hope all is well
I had in mind current version, but LattePanda Alpha definitely looks interesting. I successfully use current version of LattePanda it in my own monitoring and automation projects. Keep the good videos coming!
