Hey mate, It looks awesome so far mate, the finer details that you go into are very helpful. It will be a huge help when I get to building one for my workshop. I know that it'll be a massive help for shapes and repetitious parts 👍 I look forward to the table build itself.
Hi Rusty, I’m looking to build one of these following your design. My question is what power supply is this system running from the power point, 15A or 20A?
Hi William, the power supply for the electrical system is plugged into a standard 10A outlet....the plasma cutter is plugged into a 15A outlet. Good luck with your build and if you are looking for plans, I sell the plans for my table....if you're interested you can email me at rmhyde58@gmail.com
Thank you for sharing your experience. Newbie question here: am I right to assume that when cutting with the plasma torch, there is no lateral force on the handle? The reason I ask this question is that your stepper motors looks very big for the task ( NEMA 32 ?).
Hi Dany, yes, the torch operates approx. 1.5mm above the material being cut. The only time my torch contacts the metal, is when the torch touches off, telling the software where the torch is, in relation to the material (called ohmic sensing). I'm using NEMA23 motors, rated at 4.2A and 420 inch ounce torque....which are plenty strong enough to drive the gantry around my table.
Hi Blou, yes I did. I adapted the original 'stand off guide' that came with the torch. I then made another modification to it so instead of having the 2 fingers for sensing the material, I welded the fingers to a flat washer (which has a hole in the centre that's big enough to clear the torch tip. I can sent you a photo if you email me, it's rmhyde58@gmail.com
Great work mate, I'm currently building my own cnc mill/router and plan to make a plasma table too. I am just wondering where you bought stuff like wiring from. For some reason I cant seem to find the size of wiring I want, cheers
Hi William, I bought the 2 pair shielded cable online (eBay....7 strand, 0.4mm conductors....this is for the field devices like the stepper motors and homing proximity switches). The internal cabinet wiring from the controller card to the stepper driver units and from the stepper driver units to the aviation plugs in the side of the electrical cabinet (the output to the stepper motors) was all 6 core trailer cable. Just strip off the outer protective sheath and you have 6 cores with different coloured insulation, making it easier than buying 6 rolls of different coloured wires. The shielded cable only has to carry the stepper motor current...in my case, that's 4.2 amps. The internal wiring is probably only carrying milliamps. Hope this helps. If you have any questions, my email address is in the About tab on my channel.
Hey Rusty.. I set up my electronics on the workbench as you did but when I run the software Y1 and Y2 don’t always move the same way. In fact, there are times when Y1 will move and Y2 does not. I can’t imagine that this would be good if that happened with things hooked up. Have you heard of this one? Thanks
Hi Kerry, if you want to send me an email (rmhyde58@gmail.com) I can send you my wiring diagrams for 2 Y axis motors so you can check that yours are wired up the same.
Hi Markus, using shielded cable for all the field devices (motors, homing proximity switches, etc) is preferred. I went into more detail in the email I sent you.
@@markuspihlajaniemi3711 this is the cable I used. If you google or check out ebay for this: SHIELDED 4 CORE STEPPER MOTOR CABLE - 7/0.40 Ideally the cable will be 4 core with different colours, rather than 2 pair white and black....the coloured cores make it easier when drawing up a wiring diagram.
Hi Don, I've never had any issues with the stepper motors, or losing steps. It's important to set the steps correctly, to suit the 'distance per rev' of the stepper motors.
Hi Kerry, not sure what gauge wire I used, but I can tell you the shielded cable was rated at 10A and the internal wiring in the enclosure was 7 core trailer cable, as the maximum current is only 4.2A for the stepper motors. Hope this helps. If you would like to know more about the build, feel free to email me at rmhyde58@gmail.com
Hi Vince, I have created a series of wiring diagrams for each part of the system....power supplies, controller card to stepper drivers, stepper drivers to the stepper motors, homing switches, etc. Are you building your own plasma cutting table and if so, are you using the MyPlasm CNC controller?? If so, I'd be happy to share my wiring diagrams with you.
Hi Matthew, if you're using the MyPlasm CNC controller for your build, then I have some wiring diagrams that would suit your build. My email address is rmhyde58@gmail.com I'd love so see some photos of your build or even some videos, if you have made any.
