tosh I've followed your cmc plasmas table build very closely and build one using your plans almost to the tee. I did use open builds black box as I'm very new to this and feared the electronics and computers more than anything. It's up and running cutting out trial tabs etc. much thanks for all your help. I am struggling with significant bevel (20-30 degrees and parallel in y negative and y positive travel) on my cuts however, especially on the y axis. both side of the the tab bevel the same direction. the x axis cuts are perfect in positive x travel, and beveled in negative x axis travel. I've messed around with torch alignment, cutting heath and speed, but I'm really stretching my head. any suggestions?

Hi. Glad you were able to get your machine cutting. I'm sorry to hear about the bevel though. When I've struggled with bevel it normally is when the cutting tip is old. So I would first start will replacing the tips and see if that works. On my plasma cutter I have to replace the tips quite frequently to have nice cuts. The thickness of the material affects the cuts a lot as well. If I'm cutting on an older tip on thicker material I'll have a bit of bevel, but if I cut using the same tip on thinner material anything under 1/8" then there is significantly less bevel. Another part that causes bevel is the cut height I would make sure you're cutting that the optimal height for your machine. It should say somewhere in the manual. I think if I got a Hypertherm or some nicer machine it would cut nicer as well.

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.

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.

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

What voltage are the pulse and direction signals to stepper controllers from the BOB. Are they 5 V logic or 24V ? I cant think why the BOB needs 24V supply as well as 5V

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

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

@@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.

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.

This is the part of your build that I had the hardest time with. You did a great job with your tutorial. l had struggles with Fusion 360. The Fusion 360 learning curve was very steep for me. I do have My machine up and running. I could not be happier with the end results. I did add Proma THC along with splash rails and a water storage under the table with filters and a pump to refill. Mine sets in the shop and the water evaporation raises the humidity. I don't use it every day. It made sense to me not dragging a hose out refill. Thank You again for your excellent build video.

Hi, your videos are interesting, I created a table measuring 3300x 1800 mm years ago, I installed THC SD Proma and everything worked, now it broke down and I installed Proma 150 which must interact with Mach3. the controller I had was not compatible, I saw the LEDs working on diagnostics but the z axis did not move. I tried with a controller the same as yours with a parallel port and everything was ok but to make it work I had to install Windows 7 32 bit, I saw that you make it work with Windows 10, how do you do it?

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.

Is there a particular reason you chose to build your gantry primarily of steel? Your gantry is only transporting a plasma torch after all. It seems like the weight of steel would only increase the required size of motors, drive screws, belts, gears, bearings etc.
@ToshDavis
Жыл бұрын
Ya, there were a couple of factors why I went with steel. 1) The cost of steel is a bit cheaper than aluminum. 2) I have the equipment to weld steel but not aluminum. 3) I sometimes use the table as a wood router and wanted the extra stiffness for that. But if you plan to use it specifically for CNC plasma I would say make the gantry out of something else and save the weight.

I have a wiring question. Can you clarify why on your updater wiring diagram you have the end switch 2 and 3 in series instead of 1and 2?
@ToshDavis
Жыл бұрын
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.

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.
