MPCNC mount for Chinese 400W spindle (52mm) by jukka5 Feb 5, 2017 . Every Day new 3D Models from all over the World. I’m also designing a gantry-mounted dust shoe. 60 84 10. Should be Arduino friendly but it’s a good idea to make sure and avoid the magic smoke:). That will help. I know you used to run a DeWalt dw660. I would be pretty surprised if that needed much current at all, so a higher current circuit shouldn’t be necessary. 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. Most of these Chinese spindles are made to work with Mach3 control which would be 5v pwm from a PC parallel port or USB motion controller. Ad. New Home › Forum › Mostly Printed CNC – MPCNC › Advice – MPCNC › Chinese Spindle. MPCNC Chinese 500w Spindle Mount by Gwigga is licensed under the Creative Commons - Attribution license. it fits the 52mm 300w spindle found on Amazon. The only thing I can say so far is I’m sure it will be quieter! I like to blame the pot for this too, because it might be varying a little bit… Otherwise, it might not be something to worry about, because the PID loop should be able to clean this up a bit, although the less work it has to do the better… I’m assuming it’s not coincident with the frequency of the PWM, so if your PWM was 500Hz, you aren’t seeing +-10V at 500Hz. 1.

Can I hook the arduino directly to the power supply? Nice. I am looking forward to actually trying it out! That should be fine on a dedicated arduino. About what frequency was it changing? When I said that the voltage varies, I meant that it varies as the PWM duty cycle changes. Still not a big MOSFET though. The PID thing sounds cool! In my brief test, I had a display set up to show me the PWM output, and it was either 0 or 255. 14. How accurate/consistent should the MPCNC be? Hi Leo! 2. 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. The Triac stuff Leo was talking about is more for controlling 120VAC. You will want to make sure the sensor goes between low and high on the input pin, and either use the pulse in (might not be the right name) or an interrupt handler to measure it.

Circuit seemed to … 【CNC Spindle kit 500W】- 1 x 500W Air-Cooled Spindle Motor, 1 x AC110V/220V Speed Governor with MACH3, 1 x 52mm Mount bracket, 13 x ER11 collect, 4 x Screws(free). I just got a 500W spindle and am working on getting it set up on my MPCNC. Their wiring diagram doesn’t match the pictures. New Home › Forum › Mostly Printed CNC – MPCNC › Hardware Development – MPCNC › Tachometer for spindle. I’ve ordered the same leonardo board and button lcd shield that he used, as well as the same kind of reflective IR sensor he used. I printed the new middle and roller parts for my machine over the holidays. Thingiverse is a universe of things. u/crazy-modder. If the Shield is supplied with 12V, it is possible that less than 12V will arrive in the 12V net, because the voltage converter causes a small voltage loss. DOWNLOAD Cults. I’m guessing that 5v PWM at the Mach3 ports is what it’s looking for, though I have seen references on some CNC forums to jumpers in the power supply that might need to be set to enable PWM (not necessarily talking about this specific power supply, though). 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? 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. Lots of hours on toolpaths… Started by: zhedd in: Things You Have Made. A Chinese product that doesn’t match the diagrams?! Use M4x50mm bolts. If your spindle power supply already accepts pwm input then you’re almost there. 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. CNC 200W 52mm spindle … ReMixed Mount and Nozzle for 800 Watt Water Cooled CNC Spindle! 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. 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 like the high-tech feel of it if that makes any sense. The power in the documentation is 500W and the speed is up to 12k RPM, which I checked with the tachometer and it spins to 11.5k, so quite decent .

Chinese Spindle. In case … More about this under spindle control. 36. Close. If someone’s already figured it out, and I can adapt it, I’m fine with that too. It is not as loud as it might seem in the video. Maybe the resistance is actually going up at that end of the range. 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. If this … 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. I’ll put a piece of reflective tape on the cooling fan, and have the arduino calculate the rpms from that. 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. Anyone have a leftover Makita RT0701C fixed base? Anyway, I’m thinking about building an arduino-based tachometer for the spindle, but wanted to check and see if anyone has done it already, or is aware if someone else has done it already. Speed alone doesn’t get you much, anytime the bit makes contact the rpm’s will vary greatly. It’s hard to isolate, but I’m pretty sure it’s coming from the PWM controller. They are very common and cheap, so I thought someone might. It’s also possible the 10VDC would work with a 5V (even to 100%), and it’s just tolerant to 10V. MPCNC 65mm Makita Katsu Tool Holder . Cheap, fast to print, strong and close to the gantry. New Home › Forum › Mostly Printed CNC – MPCNC › Advice – MPCNC › Chinese Spindle. Started by: GaryW in: Your Builds – MPCNC.

I certainly expect it to be drowned out by the sound of the bit cutting material, or maybe even just the machine moving. There weren’t any docs with the power supply. I can’t give an opinion yet. Shop by Category. OpenBuilds 71mm Spindle Mount to Makita Router 65mm & Chinese Spindle 52mm Adapter Set. Dustshoe for MPCNC Artisan3 Makita Katsu RT0700. I saw a video of one on a shapoko or x-carve and it definitely looks like the way to go. This should simplify things for me. If the power is off on the arduino, and I run the spindle up with the pot, it will also start to light up the LCD – I have not pushed it to full power like this. Started by: Kevin Bergin in: Your Builds – MPCNC. The spindle of a CNC router can rotate up to 20,000 Rpm, a necessity in order to experience low torque when cutting into the material. The spindle was either slowing down or speeding up at full speed. Is anyone useing a Chinese Spindle, if so how do you like it and what one? No deflection of the cutting head by the shoe or vacuum hose. Good point about not needing to count every pulse, Jeffeb3! There is no non-chinese printing on it other than 110VAC and + or -, so there’s no model number to google. 32. ... MPCNC Chinese 500w Spindle Mount. CNC 3018 pro Spindle parts. So after reading Ryan’s post about someone working on a PID speed control for the spindle, I decided to research it myself. Now, there is a huge capacitor in the power supply, so maybe that’s what kept it running, but it seemed weird. DOWNLOAD Cults. I couldnt find a spindle mount for the chinese cnc machines. Do I need another piece, maybe a mosfet or something that can handle a higher current? I wish I was there with you testing it out. I make carbon fiber parts.
