I've wired the ohmic sensor as shown in S15108, defined Output4 as Ohmic Enabled and conducted a successful continuity check from the tip of the torch to T In on the TX board but when I touch the tip to ground I do not see the Plasma T IN led turn green as described on page 15 of the Plasma Users Ma...

Thanks for the continuing input. I appreciate it. Regarding the touch off question. I understand the circuitry but I'm trying to understand the physical connections. I found an image online that I think answers my question. The attached image shows a wire - outside of any existing wiring in the torc...

Hi, and thanks for giving me some information but it doesn’t answer all my questions. 1 – I understand the principal of the ohmic sensor and I have seen the schematic and how the signal comes from the tip, through the relay board then to the THC-TX board but how does the signal physically get there?...

I am in the process of upgrading my old DIY plasma cutter with an Acorn board, Centroid THC, Hypertherm Powermax 45 plasma cutter with a Hypertherm Mechanized Duramax 180 deg Lock Torch but I have a few questions. 1- I understand the concept of ohmic sensor touch-off but I don’t understand how it’s ...

I purchased and received a software license for Acorn Plasma "Pro" CNC Software but I can't find where to download the software itself.

Again, any help would be appreciated.

Thanks for all the replies. I think I understand it now.

I've read the post and watched videos but I'm still confused as to what torch touch off is. Can someone give me an explanation of exactly what it is and the pros and cons of using it. The old plasma cutter I'm rebuilding has a float switch on the Z axis to establish torch height. Use both, only one,...

Hi Shawn, Thanks for the reply. What you said makes sense. Do you have any idea of the current draw for the DM542Ts so I can properly size the 5VDC supply? Also, you recommend not tying the ground of the (24V or 48V) motor power supply to the Acorn 24/5V and logic 5V together. Is that right? Thanks ...

I’m reconfiguring my current DYI plasma cutter with the Centroid components as shown on their web site. I'm planning on using my existing Stepper Online DM542T stepper drivers (at 24VDC) and would like any info on how they perform with the Centroid components. I'd like to use then to save on cost. M...
