    I've updated the wiring diagram. This updated version should be a lot more clear than the one in this video. The updated version is located in the google drive folder under the name "Wiring Diagram Updated." Also, for those of you that are building it, let me know where you are confused and I will make a video to help.

    Depending on how much voltage/current is being passed through that relay at 31:17 you may need a flyback diode. If it's just DC low volt/amp to trigger the plasma, might not need it but it's good practice to put one in place and / or use an optocoupler so the circuit is isolated from the high volt/current side of the relay trigger

    • @ToshDavis
      @ToshDavis  7 หลายเดือนก่อน

Another reason I don't is that most of the material I cut is over 1/8'' (3 mm) and when it probes before every cut a THC wouldn't do much as the material doesn't warp very much

      I'm sorry I'm not entirely sure how to fix this. Have you tried making sure you've grounded everything. I'm sorry to say but your best option might be to buy a new plasma cutting machine. I know there's different starting mechanisms and one of the ways creates a lot electrical interference while the other does not. So your best bet is probably to get a machine you know will not create the interference.

I just wanted to make sure you knew the exact ones I used, but it shouldn't matter too much on which motor drivers you use as long as they are compatible with the breakout board and stepper motors you are using. The things I was looking for was that the motor driver could supply the correct current for the motors I was using. I also wanted to make sure the motor driver's supply voltage was the voltage of the power supply, so in my case 24 volts. Lastly I was just looking at the reviews and making sure people didn't have any problems.

  • @jakebonsall

    • @ToshDavis
      @ToshDavis  ปีที่แล้ว +1

      Thank you! Glad you enjoyed it. If you look at my first video th-cam.com/video/OweWXLY_zbI/w-d-xo.html you will see my old plasma cutter table. This one only had a motor on one side, no A axis and you could really only cut close to the motor because at the far end there was nothing supporting it and so it would jitter. I guess this is a long way of saying that the A axis is just a helper for the X/Y axis. It stiffens that cross beam, the gantry, up a lot where now you can cut on both sides without jittering. I'm not sure why they call it an A axis. I think it technically should just be called the Slave axis for X, but in Mach3 they already have the names X, Y, Z, A, and B and so the next available axis is A hence why it's A. I think you are right that A should be 180 degrees normally.

    what was the travel speed for those 1/2" cuts? I was doing some cutting by hand the other day with my Hypertherm 45 and at full power 45 amps it looked like a toddler was playing with my torch, horrible horrible cuts. I was probably going too fast as I was inside (it's 102 degrees outside, and dry and I have a lot of combustible grasses around the shop) I didn't want to cut outside for fear of starting a fire. Inside I have epoxy floors and even with a welding blanket it ruins the floor with burn marks.

      Thank you. On this machine I just have the z axis mapped to the page up and page down keys on the keyboard and while the machine is running I just watch the torch height to adjust it. A floating head is slightly different from a THC. It is the part that zeros the torch height before every cut while the THC is the part that adjusts the height of the torch during the cut.

    • @ToshDavis
      @ToshDavis  ปีที่แล้ว

      Not entirely sure what you’re asking. But there are “Soft Limits” this limits are limits that Mach3 has where it won’t let the machine move past this value. Though to us these you need to have your machine homed so it knows where it’s at. Though you should be homing every time anyways. You can add more limit switches if you want. The problem is the number of input pins on the breakout board. Though you should be able to wire the switches in series and use only one pin

    • @ToshDavis
      @ToshDavis  ปีที่แล้ว

      They are driven simultaneously, but they each have their own wiring and motor driver. If you can imagine only having one motor and driving the gantry from one side the other side without the motor will be able to move because it's at the end of a long beam. This second motor stiffens the whole gantry up and strengthens both sides against resistance.

    • @ToshDavis
      @ToshDavis  8 หลายเดือนก่อน

      I believe the pulse and direction signals are 5 V. But the 24 V is needed to drive the motors.

    • @1113562
      @1113562 8 หลายเดือนก่อน

      Yes 24 V is definitely used for driving the Stepper Motor coils and this is provided directly by Connecting the 24V to the Stepper controllers so why is 24V connected to the PC parallel port Break Out Board (BOB). This board is for distributing 5V signals to the controller Direction, Pulse and Enable inputs. My understanding is that the controller signal inputs (eg. Pulse and Direction) are opto isolated so do not even need a 24V reference.

    • @ToshDavis
      @ToshDavis  8 หลายเดือนก่อน

      @@1113562 Oh I see what you're saying now. After understanding your question I wasn't entirely sure as well. So this is the response ChatGPT gave me:
      Powering Relays or Other Components: The BOB might have components like relays that require a higher voltage to operate efficiently. These components could be used for controlling spindles, coolants, or other peripherals associated with the CNC machine.
      Voltage Level Shifting: While the signal inputs are opto-isolated, the board might still require a higher voltage reference for proper level shifting or for powering the opto-isolators themselves, ensuring that the signals transmitted to the stepper drivers maintain integrity and reliability.
      Enhanced Noise Immunity: Higher voltage levels can offer better noise immunity, especially in industrial environments where electrical interference is common. By providing a 24V supply, the BOB ensures that the system is less susceptible to interference, enhancing the reliability of the CNC machine's operation.
      Hope this helps! I definitely learned a lot as well.

    • @1113562
      @1113562 8 หลายเดือนก่อน

      Hi Thank you.
      Level shifting was my only thought as well but if tge stepper controller uses opto isolators these only need a few Volts. An opto isolator is only a LED and a photo sensitive open collector transistor located in close proximity in the chip. There would need a limit resistor so the diode doesn't draw excess current so I'd be surprised if the pulse, direction and Enable inputs would need or be able to cope with 24 Volts. I cannot find a data sheet for the stepper controller used to confirm what the signal voltage level range is.

    • @ToshDavis
      @ToshDavis  ปีที่แล้ว

      The 750mm was used because I needed 2 330ish mm rails (I forgot the exact dimension) for the z axis and it was cheaper to buy one 750mm and cut it in half then to buy 2 400mm (or whatever dimension I needed, I forget). If needed you could shrink the travel of the z axis or buy two of the 450 mm

Most of the time I cut thin material though I'll just lower the current setting. So instead of cutting at the max 40 amps of my machine, I'll just cut at 20 amps for example

    Hello, I am a fan from China, how do you deal with the electromagnetic interference problem when you DIY this cnc plasma cutting machine?
    My DIY cnc plasma cutting machine also used the parallel port control board and USB control board respectively. These boards all crashed or the program ran away when the plasma cutting machine started arc.
    Of course, the plasma cutting machine I purchased is relatively cheap ($100). It is estimated that this product has poor electromagnetic compatibility and is a huge source of interference.

    • @ToshDavis
      @ToshDavis  2 ปีที่แล้ว +1

      I personally haven't had any problems with interference. There is a great video by Dr. D-Flo, called "How to Build a CNC Plasma Cutter" and at 25:41 minutes in he starts talking about his interference troubles. It does seem like what it comes down to is the cheap plasma machines use high frequency to start the arc vs my machine (and the machine Dr. D-Flo upgrades to) use pilot arc as their starting method. He is able to get the machine to cut if he insulates the workpiece with wood, but he ends up just upgrading machines. Though I would still just watch the video from the given timestamp.

    • @ToshDavis
      @ToshDavis  ปีที่แล้ว

      This might be confusing because of the way I have my x and y axis set up. My x axis is the gantry and is the axis driven by 2 motors and my y axis is the carriage on the gantry driven by 1 motor. In most cases this is switched, it just made more sense in my shop location. But because the x axis has 2 motors it also has 2 limit switches and these limit switches need to be working at the same time. So that’s why they are on different circuits. The y axis only has 1 limit switch and the x axis switch doesn’t need to be activated so that’s why it can be in series. You could put the y axis in series with either switch of the x axis it doesn’t matter. Though you need to have the floating head by itself because say you had the floating in the same circuit as the x limit and whenever you hit the floating head it would trigger the limit switch stopping the code.

    Hi, i am going to build one. But i am wondering if its better to use a waterbed or a floor grate. And a big funnel under. And do i need 3 axis (do i need the torch height controller?). Or can i use 2 axis. Thanks :)

    • @ToshDavis
      @ToshDavis  2 ปีที่แล้ว

      Sweet! The water table helps keep the fumes and particles under control. It also has the added benefit that you can immediately pick up the parts after your cut. Without the water table, the parts are hot right after cutting. I don't cut very much thin material but I do believe it helps with warping during the cut of thin material as well. But my first build had no water table and it was fine it just created a lot of fumes and particles. You don't really need the 3rd axis but you will need some way of adjusting the height of the torch unless you are cutting the same thickness of material all the time. I currently don't have a THC with this machine but the THC will help a lot with your cut quality as well as making your consumables last longer.

    • @ToshDavis
      @ToshDavis  2 ปีที่แล้ว +1

      If they are the tabs I'm thinking of then it's for the tensioner system. The bolt just runs through them with the spring. I have that whole pivoting, tensioner system because I was thinking I would not be able to make the linear rail absolutely parallel with the gear rack and so any deflection, would either load the stepper motor shaft or unload the stepper motor shaft and so this whole system is designed to help keep the same amount of tension on the stepper motor shaft throughout the linear rail travel

I think if you welded the ends that would help with that moment. But honestly, I think the moment is small enough it wouldn't be a big deal. With metal compatibility, I think you're fine. When I drilled the holes the rack drilled nicely so I don't think the metal is hardened in any way.

      Hi to elaborate more on your question. The machine is grounded through the power cables. At the timestamp 19:21, the green cable at the top that is running between the wall and the power supply has a ground lead that is hooked up, along with the power and neutral lines. And through the metal box, everything else should be grounded. Sorry, it's not very clear in the video. It does seem like the main cause of interference is the plasma machine. If you're having interference problems once the torch starts up I would watch Dr. D-Flo's video, called "How to Build a CNC Plasma Cutter" and at 25:41 minutes in he starts talking about his interference troubles.

      Hi Andrew sorry for the slow response not sure if you figured it out or not. It's hard to tell without looking at the code, but it seems that after the G31 command the controller is tell your torch to go to some very high number. Or the G92 command is not resetting the z axes to zero. You can check, but the commands should go something like
      G31 Z-100 F10 (This just tells the z axis to go to -100 at 10 in/min or what ever units you have set. But it's also waiting for the probe command and will continue to the next step if the probe is hit. The -100 is just some arbitrary number to just have to go really far down)
      G92 Z-0.25 (This is the command that might be messed up. This basically says to now set the z axis to -0.25. This is the command that zeros the axis. You have to set this to what ever the offset of your floating head is.)
      G0 Z0.71 (This is just saying for the z axis to now go to 0.71, or what ever you want the probe height to be.)
