    Langmuir Crossfire DIY THC - questions

    Guys, I'm fairly new to CNC plasma. I am doing a somewhat ambitious project and realized right away that a cnc plasma table without THC is very limited. I will be adding THC to my table, but have a few questions. Your wise thoughts would be much appreciated.

    1. There is so much information out there on this topic that it's difficult for a newbie to sift through and get the real scoop.
    2. With the Crossfire, I believe I will need a Z-axis such as the Rattmmotor CBX1605 (https://www.amazon.com/Actuator-CBX1...22&sr=1-3&th=1), a floating head slide such as the KARVECUT-25 MM CNC FLOATING PLASMA TORCH HEAD (https://step-motion.com/products/25-...mount-assembly), 2 limit switches for the Z-axis limits, and a THC controller kit. Is this list complete?
    3. Which DIY THC controller kit makes sense for my application? Where does the term "standalone" come into play?
    4. Langmuir wants $750 for this add-on. It seems like I can DIY this for maybe $300 and learn at the same time. Yes, no, crazy?

    Thanks in advance, guys.

    Re: Langmuir Crossfire DIY THC - questions

    With KARVECUT-25 MM CNC FLOATING PLASMA TORCH HEAD (KARVECUT-25 MM CNC FLOATING PLASMA TORCH HEAD) you are ready to go.
    You can find settings online,on how to set it up with Mach3.
    You can also purchase the Z axis specifically design for small plasma tables,like Langsmuir.
    (https://www.ebay.com/itm/114942262002?).It has floating heat attached to it.
    Those guys they can make mounting back plates (free) to fit on your gantry.
