Welcome to the group! Lots of bright folk around here all willing to assist.
I have an early 2’ x 2’ Crossfire running on Mach3, a Prime Weld CUT60 and a home-brew THC. Love my machine, use it very often in my shop, It’s been a great investment. So, you’re not new to CNC, water jet and plasma, I foresee you having no problems getting up and running.
Thank you! Yes I use Solidworks everyday, the waterjet programs and torchmate did automatic gcode generation in the nesting software so it sounds like I will have to learn a little bit though, but im looking forward to it. How did you build the THC I am leaning towards buying a bare bones table and adding to it as I go since 3/16" sheet should stay pretty flat
The trickiest part of adding custom THC is designing a Z axis that supports Initial Height Sensing that doesn’t create undue pressure on your workpiece (this creates an error if it deflects the workpiece). The THC part is easy.
As long as your table Gantry arm (X Axis) is supported on both ends, then you can probably get away without THC or Z if you use thicker materials, like 3/16". The cantilevered arms are hard to maintain planarity with the table. The double rail systems can be adjusted and pretty much keep their alignment.
Just had a long discussion with a buddy of mine, he has the space in a huge warehouse he owns and we’re thinking of partnering and investing in an XR with a Hypertherm Powermax 125. He just returned from a vacation in Portugal and was blown away by some sheet-metal work done there. I think there’s lots of scope for such a machine here.
I’ve had a plasma cutter for nearly 20 years and a crossfire pro for less than a year. The plasma table is something I wish I had gotten into 15 years ago. I use it a lot more than I thought I would, even for quick little things.
I run a powermax 65 and have a liner in the water table when I want to run 65 amps. I run it at 45 for thin stuff. I like having the option of doing thicker material, I’ve already done a few 1/2" projects.
