As for determining the optimal speed for aluminum, I have … Started by: Kevin Bergin in: Your Builds – MPCNC. Any advice, or even a link to info about this, would be appreciated. The triac circuit will be high voltage across so it should be optoisolated from the Arduino circuit for safety reasons. Hooked up an arduino to the PWM input on the power supply (meant for Mach3 control, I think)? Spindle … New Home › Forum › Mostly Printed CNC – MPCNC › Hardware Development – MPCNC › Tachometer for spindle. I originally tried using a mini IR sensor (usually used for bed leveling) for the tach, but it didn’t work right. So after reading Ryan’s post about someone working on a PID speed control for the spindle, I decided to research it myself. 3. But there are many discussion about bits and speeds here and on every other CNC forum, and it seemed to me that without being able to actually measure and control the speed of the bit, knowing what the speed should be for a given bit and material is a moot point. December 30, 2017 at 8:37 am #50226. I didn’t measure the output when I had the pot disconnected. About what frequency was it changing? When I said that the voltage varies, I meant that it varies as the PWM duty cycle changes. I then unplugged the motor from the power supply, and the arduino continued to run! Or is the way you suggest more accurate? I do love figuring out how to do things myself, but it can be tedious and frustrating. DOWNLOAD Thingiverse. ... MPCNC Chinese 500w Spindle Mount. Hi Leo!

That can/should make a very noticeable effect on your future cuts. DOWNLOAD Cults. All I was able to ascertain was that the input affected the speed, but I need to play with it a lot more before I understand how to set it up properly so that it actually holds the speed steady. ReMixed Mount and Nozzle for 800 Watt Water Cooled CNC Spindle! Those of you who are experienced coders can probably do all this with any combination of controller and sensor you have at hand, but if you want to put this setup together, here’s what you need: Spindle and power supply – $135 Arduino Leonardo – $11 LCD Keypad shield – $11 IR Sensor – $7 PWM Controller – $17. CNC 3018 -- 300W Spindle Mount. CNC Spindle Motors. 30. A zero Cross detection circuit is also needed to find the exact point in the AC sine waveform where the triac switching should start. Chinese Spindle and helper springs. I’m also in the middle of upgrading all the parts on the MPCNC, which is an early model, so I still have a way to go before I’m actually cutting with it. Back to the subject of this thread: I hooked up a PWM output to the Mach3 input on the power supply this evening. In-depth test of Chinese 500W CNC spindle as an alternative to the Dremel. Image. Interesting. Im a big Linux user myself but keep all my 3D printing / arduino / cnc stuff on a seperate windows machine. When you get your PID in there, if this potentiometer is affecting it, your control loop will be trying to compensate, which, with an integrator, can cause some goofy issues, so hopefully you can just disconnect it, or just jumper it to ground or whatever that red is (5V, 10V?) Thingiverse is a universe of things. Did you try looking at the voltage at the motor connector when you had it on before, and when you had it at 100% with the arduino? How would you say your current spindle compares as far as noise, power, speed, and quality of cut? Bill Of Materials Printed Parts. Download files and build them with your 3D printer, laser cutter, or CNC. Get it as soon as Wed, Nov 4. … You’ll need a triac to drive the load. 28. Just dialing some things in.

No deflection of the cutting head by the shoe or vacuum hose. The big advantage of an arduino (other than it’s cool, and you’ll learn a lot) is that you can then go the next step and control the speed of the spindle with closed loop feedback. It could be a bad pot. 0 comments. You could do it without interrupts, if that’s what you’re asking. Otherwise, it might be a pulse input, like an RC controller, but it still wouldn’t hurt it to have it connected, it just wouldn’t work. You could also measure the current that way, although I would be very surprised it if was anything significant. 5; 8; 4 weeks, 1 day ago Barry. Jun 07, 2019, 08:50 am. I can’t give an opinion yet. 60 84 10. Yes I use these kind of spindle. The cheaper spindles will be fine for cutting one or two mold cavities a week. Ad. DOWNLOAD Thingiverse. Their wiring diagram doesn’t match the pictures. Good point about not needing to count every pulse, Jeffeb3! I would think that it would be at 100V at max. If you just connect the red pot wire to the yellow PWM, does it go full speed? Do I need another piece, maybe a mosfet or something that can handle a higher current? 55. With this stuff you really want to be on windows. MPCNC Gallery; LowRider CNC Gallery; Older Gallery; Social; Forums; Contact; Select Page. It’s also possible the 10VDC would work with a 5V (even to 100%), and it’s just tolerant to 10V. Liked By View All Give a Shout Out If you print this Thing and display it in public proudly give attribution by printing and displaying this tag. I would be pretty surprised if that needed much current at all, so a higher current circuit shouldn’t be necessary. Your Arduino will need to read rpm, handle PID loop, and apply phase control to the outgoing AC through the zero cross and triac input/output. So when the output voltage is about 50V, you are seeing +-10V oscillating? However, I just did some more testing, and here’s an example of the voltages. FREE Shipping by Amazon. Then you can stop measuring, and go handle your LCD. MPCNC universal mount holder for 52mm spindle. You can use 2 to 4 of them (I'm using 3 and it seems already overkilled).

The spindle was either slowing down or speeding up at full speed. New, Revised, BURLY, MPCNC Center Parts. Also, as the program continued running, the amount of power feeding into the arduino varied at each PWM point (judging by the brightness of the LCD). It also is compatible with their added spindle motor that can turn dowels and spindles in a 4th axis for automated machining of cylindrical objects. I certainly expect it to be drowned out by the sound of the bit cutting material, or maybe even just the machine moving. For this case the jumper JP17 is provided. Greetings, Was just looking for comments making sure I did not mess anything up before I order a PCB. Viewing 2 posts - 1 through 2 (of 2 total) Author. @karl . Every Day new 3D Models from all over the World. Ad. I expected the spindle, which was still running, to settle on a single speed, but it continued to cycle, so I realized that the EMF I had observed before must actually be powering the arduino. It has a massive working area with 28” x-axis and 50” y-axis with 7” z-axis travel and ample space outside of that area for affixing your clamps. 7; 18; 6 days, 3 hours ago Ryan.
