Acorn Plasma CNC THC Control: a closed loop DIY Torch Height Controller (THC) kit

Acorn Plasma CNC THC control kits are both a CNC Hardware and CNC Software DIY system designed to work together for easy CNC setup and operation with minimal fuss.

A reliable, high performance, industrial quality Plasma CNC controller with a real time closed loop Torch Height Control at a do-it-yourself price. Acorn utilizes an integrated 1Ghz ARM Cortex A8 Motion Control CPU and communicates with CNCPC via a fast and reliable Ethernet connection. The Acorn CNC control board controls a wide variety of axis motors and drives with industry standard step and direction command signal. Compatible with AC brushless servo motor drive packages such as: Clearpath, Delta, Estun, Yaskawa, and many others as well as Stepper motor drives such as the popular Gecko and Leadshine stepper drives and many others. The Acorn CNC controller runs on Centroid's proven industrial quality CNC control software.

Centroid announces that now our Plasma THC is now compatible with the PrimeWeld Cut 60 and the Everlast i and s series CNC plasma cutters (in addition to Hypertherm, Lincoln, and Thermal Dynamics).  Centroid is now offering a Plasma CNC and THC kit for the Cut 60 and the Everlast units. Available now for purchase below.

Centroid's Torch Height Controller closes the loop between Plasma Arc Voltage and Torch Height via high-speed fiber optic communication.

The Centroid Acorn THC kit provides real-time closed loop operation between the arc voltage and the torch height. The THC reads the arc voltage and sends that information to the Acorn controller via fiber optic isolation to Acorn's high-speed encoder port.
 
Part #15322 for PrimeWeld Cut60 and #15321 for Everlast i/s series include the special Centroid "CNC" cable from the Cutter to the Centroid THC Kit
 
Requirements:
- Acorn CNC controller kit (Acorn requirements are here)

    • 4x 1k Ohm SIP resistors for 12 volt input

The Ether1616 is an input and output expansion board designed to be used with the Acorn CNC controller. Each Ether1616 board adds an additional 16 optically isolated inputs and 16 relay isolated outputs to the Acorn CNC system, up to three Ether1616 boards can be added to an Acorn system for a total of 56 inputs and 56 outputs. Three different input voltages can be used: 5 volts, 12 volts and 24 volt. Input voltages are mix and match capable and are selectable via bank of four of inputs at a time with the provided plug-in SIP (Single In-line Pack) resistors. The default input voltage is 24 VDC.

Both the Ether1616 and Relay 8 modules provide both Din Rail mounting holes and Standoff mounting holes to allow the DIY installer a wide variety of mounting possibilities!

The provided dedicated power supply is sized properly to provide enough power to drive the 16 relays. There are indicator LED’s on Ether1616 Inputs and on the Relay 8 Modules that indicate the state of the Inputs and Outputs.

The Ether1616 as the name implies communicates with the Centroid CNC12 software via Ethernet connection to the CNC PC. Ether1616 documentation is here.

Centroid Acorn CNC controller reviews

Looking to order boards and other parts from you this week. I've got to admit - SO NICE having a board and software made by the same company. No plug ins from other places and the headaches. Literally followed the video and the motors were turning by the time it was done.

After dealing with Mach 3 and LinuxCNC for years, I must say Centroid is Light years ahead. Up and running bench test in a matter of minutes instead of days as with those other products. There is much to learn about Centroid but I am confident it is a very solid product. I can't find the words to properly describe the difference.

My son came to me and said that the students in his high school woodworking class could not finish their projects due to their CNC router is broken. Well I couldn't let this be and in less than an hour, I installed a acorn on their router and all the students were able to finish their projects. I donated the board to the school so they could continue to use the router and many students will be able to familiarize themselves and use the Centroid control. Thank you Centroid for making such an awesome easy to use and install product. Keep up the good work!

I have to say a big THANK YOU to Centroid for providing the best value in DIY CNC on the market today. I just completed the upgrade of my CNC router table to Acorn and couldn't be happier! Followed the schematics for the GeckoDrive 203V (only thing I kept from my old controller) and everything just worked without any issues. Watched a lot of video's that provided almost everything I needed to get my machine working. I saved so much money over upgrading to Mach4, Smooth Stepper and PMDX boards that I had planned for my initial upgrade that I bought a touch screen monitor, wireless pendant and upgraded to Mill Pro. The pendant is just amazing to use. I feel like I have a professions system now! Not sure how you can sell the entire acorn kit for the price you do, but thank you for providing this to the DIY community.

Yesterday, I received a model 4 Acorn and an extra relay board for my model 3 Acorn that I bought almost a year ago. Opening that package reminded me of the care and concern that Centroid has for its customers. The power supply was pre-wired for the Acorn. The instruction sheet is comprehensive. The backside of the instruction sheet that shows a connection schematic that should make initial connections fool-proof. I just noticed that even those schematics are printed in color. (My eyes have serious problems.) The new schematics that Keith notified us of have fixed all of the connection problems that I've experienced with ClearPath servos, Gecko G203 drives, and Leadshine (clone) drives. Those problems were not Centroid's fault. (The older schematics followed wiring diagrams from other manufacturers that were somewhat lacking. I've read Teknic's manual carefully about the fault signal. The older schematics followed the Teknic manual. Keith and Gary solved that problem months ago, but because I had a work-around, I didn't carefully read the revised schematic that Centroid published months ago.) I was able to work around those problems; but the new schematics make those work-arounds obsolete. It amazes me that Centroid is willing to spend money on so many do-it-yourself motors, drivers, spindles, VFDs and other non-Centroid products, test those products, draw up schematics to use those products and still sell the Acorn for $329 with the amazing Centroid software.

Next, the forum along with YouTube videos are great. Keith, Marty, Gary and Franco not only show how to use the Acorn, but teach general principles about CNC machining. Late last night when I couldn't sleep, I watched a video where Keith showed how to use a vertical mill. The video contained everything that anyone would need to see how to use Centroid products to make their equipment work. Clicking on "Acorn User Videos" from the Acorn page shows a list of videos that show how to use the Acorn. Going on YouTube and searching "Marty CNC" brings up Marty's channel with a comprehensive list of how-to videos. Searching "Gary Campbell CNC" brings up Gary's channel and his expertly produced videos. (Gary and I go back decades to my Shopbot days when I constantly used his advice to solve my problems.) Clicking on "Centroid CNCKeith" brings up Keith's videos. His knowledge and easy-going style should make anyone comfortable in trying an Acorn. One of his videos was with "MecTechMike". Mike's mill and lathe conversions should impress everyone. He surely impressed me and gave me ideas that will take at least a year to try. There are many, many others who have taken the time to post videos showing how they use the Acorn and other Centroid products.

The forum is invaluable. Questions are answered expertly (in most cases). Since I tend to be disruptive in some of my posts (unintentionally - I like to think outside the box and try things that might seem to be controversial), I expected harsh feedback or even censoring, but I've been treated with respect and courtesy. More, importantly, by reading what others are doing, I get ideas that would take a life-time to implement.

Thanks Centroid and thanks to all of you in the Acorn community for your help.
