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. Close. Do I need another piece, maybe a mosfet or something that can handle a higher current? If the only connection between the motor and the arduino is the PWM, and the wall A/C, then I think you probably need to isolate the PWM signal. The triac circuit will be high voltage across so it should be optoisolated from the Arduino circuit for safety reasons. 14. If one of those would work with this spindle, it would be easier than building my own. Favorite; I printed this design; Add to collection; BySabin Iacob. Started by: GaryW in: Your Builds – MPCNC.

Lots of hours on toolpaths… Started by: zhedd in: Things You Have Made. I started at a level that had the spindle already spinning, so there’s a voltage even at 0 PWM. That should be fine on a dedicated arduino. Now, there is a huge capacitor in the power supply, so maybe that’s what kept it running, but it seemed weird. The measurement is for the Outside Diameter of the conduit/rails/tubing. 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. It is a chinese power supply and has inputs that are supposed to be for Mach3 control. You could also measure the current that way, although I would be very surprised it if was anything significant. I printed the new middle and roller parts for my machine over the holidays. 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. Thingiverse is a universe of things. 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. All the printed parts for the US 3/4" conduit version are here on Thingiverse and the metric versions are in the links on that page 25mm, 25.4mm. Bill Of Materials Printed Parts. I glued a piece of a gift card to the spindle (the “fan” part at the top of the spindle, actually), and mounted an opto endstop so that the gift card “flag” passed through it. I saw a video of one on a shapoko or x-carve and it definitely looks like the way to go. I didn’t measure the voltage, I’ll try later. Please measure your rails before printing. Every few seconds? The higher RPMs are only really necessary for milling with smaller sized bits, because you need to get those teeth … it fits the 52mm 300w spindle found on Amazon. 65 121 7. I just got a 500W spindle and am working on getting it set up on my MPCNC. The spindle can turn up to 12000 rpm, so I hope that this setup can handle that. Karl mentioned something about Mach3.

As for determining the optimal speed for aluminum, I have … Here are some of the things I observed: With the pot turned to zero, the PWM signals did nothing. But that was only with the PWM connected. When I said that the voltage varies, I meant that it varies as the PWM duty cycle changes. DOWNLOAD Cults. I might just make a sketch to output different duty cycles to those terminals and see what it does. That can/should make a very noticeable effect on your future cuts. With the pot turned up anywhere from just barely turning, or almost ready to turn, the PWM settings caused it to start, and run faster at each level. Any advice, or even a link to info about this, would be appreciated. Or is the way you suggest more accurate? mpcnc; universal mount; 52mm; hicwic; spindle… 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. A Chinese product that doesn’t match the diagrams?! Viewing 2 posts - 1 through 2 (of 2 total). 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.

The cheaper spindles will be fine for cutting one or two mold cavities a week. It would be smart engineering to read the docs first. Newbie; Posts: 20; Karma: 0 ; Chinese 500w Spindle controller . I would measure it with a multimeter. Should be Arduino friendly but it’s a good idea to make sure and avoid the magic smoke:). So when the output voltage is about 50V, you are seeing +-10V oscillating? 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). You do need 3 pieces of software: - GRBL configured and uploaded to the arduino uno via … DOWNLOAD Thingiverse. I’m also designing a gantry-mounted dust shoe. Hooked up an arduino to the PWM input on the power supply (meant for Mach3 control, I think)? Alright guys, this is a culmination of weeks of reading, researching and determination. Cheap, fast to print, strong and close to the gantry. u/crazy-modder. Post your sketch when you get a chance . Well i got the mpcnc going sooner than i thought.

I started with a sketch that incorporates the PID library, and I’m ready to try using the PID part of the sketch to control the spindle speed. CNC 3018 pro Spindle parts. I might keep the 660 handy for things like dressing the waste board, since it will easily turn my 3/4 inch end mill, but I have high hopes for doing more precision stuff with different materials. 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. Anyway, that’s why I’m asking if anyone has any experience with this specific spindle and power supply. 2. You could do it without interrupts, if that’s what you’re asking. Instead of timing a certain number of pulses, could I just count the number of pulses in a specific amount of time, say 10 seconds, and calculate from that? 1. 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. 34. 2.5w Diode Laser Module 1x $75: 400W 12000rpm ER11 Chuck CNC Brushless Spindle Motor and Driver 1x $80: Printing .

CNC 200W 52mm spindle … Unless the pot was turned up pretty high, the PWM signals would not get it turning beyond about 8000 rpm, and if turned up high enough, the higher PWM signals actually made it slow down. Can’t wait to see how it handles load changes. I have both the DewaltDWP611 and a 300w DC spindle, and the 611 can achieve higher RPMs and has more power, but I wouldn't mind using the DC spindle for smaller stuff that doesn't require the extra power. A zero Cross detection circuit is also needed to find the exact point in the AC sine waveform where the triac switching should start. That controller should be here tomorrow, so we should know this weekend. Yes I use these kind of spindle. DOWNLOAD Thingiverse. Shop by Category.
