DOWNLOAD Thingiverse. Thanks for your input! Doing the first crown test and it went perfect. DOWNLOAD Thingiverse. I would like to introduce you to the new "Burly" parts. Details on that to come. I don't have a lowrider but the classic mpcnc. Here are a couple of other pics, one of my breadboard for the project, and another of the spindle with the tach sensor mounted on it. 12000 rpm is 200 Hz, which is 5ms/measurement. DOWNLOAD Cults. I haven’t put the machine back together yet – waiting to get the PID speed control done. But I haven’t ever owned one of these. MPCNC 52mm Spindle Mount . Speed alone doesn’t get you much, anytime the bit makes contact the rpm’s will vary greatly. Viewing 2 posts - 1 through 2 (of 2 total). I won’t be able to test a realistic load until I get it mounted on my MPCNC, which I’m still putting back together. The voltage output to the motor varies over a range of maybe +/- 10vdc as the PWM cycles, centered around whatever voltage the rheostat is set to. Now, there is a huge capacitor in the power supply, so maybe that’s what kept it running, but it seemed weird. One input is labeled “0-10vdc signal”, and the other is a potentiometer. I post them here in case someone can decipher the behavior and give me an idea of how to get it all working. 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). 4.2 out of 5 stars 69. Every few seconds? To answer your question, there is the “super PID” and one of our local mad scientists is close to his own, much less expensive version. So when the output voltage is about 50V, you are seeing +-10V oscillating? That way if you set 1000 rpms, it will do it’s best to vary the power to keep 1000 no matter what. Chinese Spindle and helper springs. How accurate/consistent should the MPCNC be? 59. I didn’t measure the voltage, I’ll try later. ... MPCNC Chinese 500w Spindle Mount. It could be a bad pot. Back to the subject of this thread: I hooked up a PWM output to the Mach3 input on the power supply this evening. 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 do it without interrupts, if that’s what you’re asking. The arduino PWM output is definitely controlling the speed of the spindle. https://www.amazon.fr/gp/product/B0716S2SF9/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1. Thingiverse is a universe of things. Newbie; Posts: 20; Karma: 0 ; Chinese 500w Spindle controller . You can use 2 to 4 of them (I'm using 3 and it seems already overkilled). So I thought, hey that's not bad, despite the crappy dremel knockoff it's using as a spindle. The mount is designed for the new "Primo" version (F 25.0 mm) and is screwed directly to the Z-tubes. 5; 8; 4 weeks, 1 day ago Barry. Interesting. If the spindle is turning fast enough, it generates power that feeds back through the LCD, which gets darker (more pixels turning dark) until it’s unreadable, just solid blocks. As for determining the optimal speed for aluminum, I have … However, I just did some more testing, and here’s an example of the voltages. Well i got the mpcnc going sooner than i thought. Hopefully ill attempt to cut a little piece of wood later today and see how it goes. Typically the frame and bearings of a CNC router are not configured for high stiffness. But that was only with the PWM connected. The other thing working for you is that you don’t need to measure every pulse, just measure the time for one pulse, ten times or so, and then average them out. Obvisouly a $350 Chinese spindle is not going to match the quality of a $3500 European spindle but milling aluminum is not my main business. Just polling the pin at a high rate, for 50ms, which should give you at least 9 pulses, and average that The interrupt version would be fairly simple, and it would be nice when you start adding other things to the arduino. Steer clear of the Chinese downloads, they tend to include bloatware and other bad stuff. I would be pretty surprised if that needed much current at all, so a higher current circuit shouldn’t be necessary. I won’t learn as much, but it seems like a great solution. I will continue trying to eliminate or mitigate it. I’ve downloaded his code and hope to use it with maybe only a little modification. I recommend 24V. MPCNC End Stop Block. 9 months ago. I just got a 500W spindle and am working on getting it set up on my MPCNC. I’m also designing a gantry-mounted dust shoe. I also ordered a spindle. Anyway, I don’t like the EMF feedback (or whatever it is), so I’ve ordered a PWM controller like this: https://www.amazon.com/gp/product/B00HUQY9HC/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1. That can/should make a very noticeable effect on your future cuts. This topic contains 1 reply, has 2 voices, and was last updated by Jacques 1 year, 10 months ago. 7. so i designed one and thought i would share it. It’s also possible the 10VDC would work with a 5V (even to 100%), and it’s just tolerant to 10V. Do you have a data sheet for your power supply? Get it as soon as Wed, Nov 4. Alright guys, this is a culmination of weeks of reading, researching and determination. No deflection of the cutting head by the shoe or vacuum hose. I originally got the spindle just to have something quieter than the screaming 660. This definitely looks like a high impedance input. Image. 60 84 10. 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. That controller should be here tomorrow, so we should know this weekend. Their wiring diagram doesn’t match the pictures. I printed the new middle and roller parts for my machine over the holidays. I use a chinese 500w spindle, very nice but I'm struggling to keep it cool. With the pot disconnected, and only the PWM wires connected, nothing happens at 64, it turns at 1100 rpm at 128, 2400 at 192, and 4400 at 255. This topic contains 1 reply, has 2 voices, and was last updated by Jacques 1 year, 10 months ago. If your spindle power supply already accepts pwm input then you’re almost there. … That should be fine on a dedicated arduino. Creality 3D® Ender-3 V-slot Prusa I3 DIY 3D Printer Kit. You do need 3 pieces of software: - GRBL configured and uploaded to the arduino uno via … To ﬁx the body and cover, 10 M5x25 screws and M5 nuts are required. I too like the high-tech feel of it. DOWNLOAD Cults. New Home › Forum › Mostly Printed CNC – MPCNC › Advice – MPCNC › Chinese Spindle. 34. There’s no piezo I can find anywhere. When I said that the voltage varies, I meant that it varies as the PWM duty cycle changes. 3020 CNC + Arduino + GRBL + CNC Shield V3: Let's convert an inexpensive Chinese CNC machine from Parallel Port to Arduino and GRBL. CNC 200W 52mm spindle … Follow user. You might also try just connecting a power supply with 5V to the input, and see if it goes to 100%. 18% Off. CNC 3018 -- 300W Spindle Mount. CNC Spindle Motors. It is a chinese power supply and has inputs that are supposed to be for Mach3 control. MPCNC … The PID thing sounds cool! I’ve done a few projects with arduinos, but I’m still pretty new to them, so if you’re knowledgeable about them and have some ideas about how to approach this, please share your thoughts about this project. Was just looking for comments making sure i did not mess anything before. Was there with you testing it out, and the arduino circuit for safety reasons shapoko.
