Thanks a lot for sharing your experiences with this spindle! I'm also about to build my own CNC machine with this 500W spindle. Good to know I have to envision something more stable than I originally thought. :)

Great video. I can't wait for you to make a bigger CNC with rugged construction like you mentioned at the tail end of the video. :)

For those saying he is spinning too slow, it comes down to surface speed and feed rate. Appropriate surface speed varies per material. Feed rate ensures that you actually produce a chip without "burnishing" the material.. This causes excess heat, and short tool life. High RPM means high feed rates. High feed rates means more torque for your steppers, more tool pressure, and therefore more stiffness required in the gantry and such. It is all a design tradeoff... I like the video and I have always wondered about the air cooled spindles.. I have one of the chinese water cooled ones, and even at max RPM they are nearly silent.

so nice that you build this! as I saw your Dremel CNC video I was so impressed and started to build my own! then I see the same spindle on banggood and buy it! I don't have all the parts for my CNC machine but in maybe 2 months my machine is ready to mill! Thanks for the Tipp to use Nema 23 Motors!

😂 I love your enthusiasm and curiosity. “It’s beginning to sound like a new project. 🤔 Maybe!”

Thanks!

you want to use a down cut, or compression endmill on wood so you do not rip the edge upward. this will result in a much cleaner cut. i also find with MDF both of these end mills leave the perfect amount of dust packed into the cut to hold a 1/8" profile cut in place without any tabs or tape to secure the cutout portion. some woods might work well with a straight flute endmill also. For Acrylic you want an upcut so that the material is pulled out of the cut otherwise is will melt back into the channel metal, an upcut is normally desired as you want to remove the material from the cut to prevent binding issues. Totally awesome job on the builds. One thing i was thinking is maybe you could come up with a sleeve that would go around the jacket, or even coil some copper tube around the body of the new spindle (CPU thermal paste too?) and use a small water pump to cool it like the industrial CNC units ;)

I liked very detailed keep all future vids that way thanks

thanks that was really helpful, might just have saved me a lot of tinkering :D

Hi Nikodem, On a side note. You should definetly use a dust mask when milling MDF. It releases som toxic fumes(urea-formaldehyde) and also a lot of fine dust/particles. Also you should consider a ventilation system to ventilate the toxic fumes. One option is to enclose it and use extraction on the enclosure. Preferably leading the fumes/particles outside. Other than that, great video :) Daniel

Now that you have a pretty good CNC machine, you should try to start milling alluminium parts to replace the 3D-printed parts. You should have better results, as aluminium should be a lot more stable (even with the dremel).

I like how Ryan at "Mostly Printed CNC" does things. He's open source, but has a store for parts if people wish to buy parts. People buy other parts from him if they wish and print their own printed parts.

I've had experience with DIY CNC machines, I've picked up some broken leafblowers and repaired them to make an extraction hood. If it pleases you, you can also attach a heat sink and use it as a method of cooling the spindle

What an awesome project

Great video! And great project! I just build the dremel cnc and I'm wondering, your machining settings. You shared the ones of the new splindle in aluminum. Can you share the setting for aluminum and wood for the dremel?

I love your channel,you're coolest guy🤘🤘 peace ✌

Part of the problem with the wood appears to be the Endmills being used. You may want to use a down cut end mill with wood and use a upcut for aluminum.

@PiefacePete46

4 жыл бұрын

I totally agree. Other factors are, I think, the MDF Nikodem used is not great quality; lots of fibre and not much resin, and the wood wasn't great either. It would have looked even better with a downcut bit, some nice wood like carvers use, and free-machining aluminium such as 6061. I don't think it's rigid or powerful enough for a compression bit. Great little machine to learn from, but like a lot of people, I am really looking forward to his new design.

Have you thought about making it multipurpose ? An adapter to swap out the Dremel/CNC spindel with laser would be a great feature so you could also laser etch with it.

Hey. and you are going to put limit switches on the CNC ?? it would be convenient to determine the home points

C’mon build a new CNC. Use yours to recreate the 3D printed parts. Keep going, nice vids

Hello! Your channel is interesting and I'm wondering if a new version of this printer will come out! Maybe with nema 23!

I think you need to mount a vacuum onto the cnc near the bit. With all those chips building up it'll retain much more heat and the airflow caused by the vacuum will help to cool it.

Have you checked the spindle rotation direction, also you seem to be routing with the spindle a bit slow.

Great machine and great videos--thanks for that! I built one but used some of the other remixes on thingiverse (offset x-axis carriage to change the center of gravity). One thing i'm noticing though is there is quite a bit of play on the Y-axis bearings--is this just mine or did you notice it on yours as well? I find that as soon as the 500W spindle is loaded on, it pulls the carriage down and toward the front due to its weight.

Hello Nikodem Bartnik , I love this project and I´m doing mine with a 500w Spindle. I would like to know If you will create a vacuum support like the dremel have. Thanks.

I very impressed with this project. So did you address the resolution problem? Witch leadscrews did you put, with what pitch?

you can try two motors on each side of the leadscrew (turning in opposite direction!).. so eventually have 2 for x and 4 for y.. get motor driver extensions and drv8825 for higher violtage.. maybe 48mm deep nemas.. nice project btw :)

You can use dremelcnc to make aluminum parts for bigger 500w cnc, then use that to machine steel parts for even bigger cnc!

Keep on experimenting. That is how we learn :)

You know your talking to a college student right? Why the elementary comment?

Those spindles usually have a lot of axial play, that's why I wouldn't use it a spindle. As a motor for a dedicated spindle, those are awesome.

Congratulations, it's a very good project. I would have a question, how many minutes is the cutting time of the parts that cut? Could you give information?

Im building a way larger machine than yours but I am also building a smaller machine like yours and appriciate you taking the time to compare both . Thank you

Hi, I noticed that there's some gutting tool chatter on some of the surfaces that have been cut.Is this due to a too high feed rate of the stepper motor not being powerful enough? Or is there too much power for the hardware-constitution to handle? Great video!!

I think you can test to put epoxy resin into the printed parts ( in this case you have to use less infill ) what is the pitch in this acme screws?? Thanks

Great video. Ive been thinking of an interesting project where you build the CNC out of 3d printed parts and then use said CNC to mill the same parts out of aluminum essentially upgrading itself. Doesn't really solve your motor or unsupported rail issues but all the fixtures would be sturdier...

For better results, and less "tear out" use down-cut spiral / rotary bits for wood. For machining metals such as aluminum, it's better for hobbyists to use single flute end mills, this will allow you to run the spindle at higher speeds, and still maintain a decent chip load. It's also a good idea to use coolant with hard metals, and lubricants / lubricating coolant with soft metals. Soft metals such as aluminium will gum up in the flutes, and can "chip-weld" themselves to your end mill. This will eventually result in a broken end mill. All that said.. I think what you're doing is pretty neat. Keep it up!

Hello from Russia! Thank you!

I JUST NOW ordered an "authorized refurbished" Makita rt0701c compact router for my MPCNC build. I saw a side-by-side comparison in their forums. I'll let you know how good it is. I have one of the older Dremels with the less ergonomic designs and so I'm hoping to use that one in the Dremel CNC. Because of the straighter casing, it MAY be easier to mount.

good job!!!!!

Hello, I also have such a motor (48V). It was working before, but yesterday, while scraping wood, the motor had a hard time and suddenly stopped. Now it doesn't work at all. I measured it with a multimeter. There is electricity (48V) at the output of the PWM driver and the positive and negative terminals of the motor are powered, but the motor does not move. What do you think might be causing the problem?

Getting rid of the brass nuts and 3d printed parts will stiffen up the chc allowing for faster feedrates and cleaner results. Check out delrin anti backlash blocks. Not expensive yet still quite good. Use compressed air to bliw away aluminium chips, that prevents gumming up the endmill. Using aluminium extrusions as frame is a step up, alliwing you to use bigger spindles and nema23 steppers. Cost quickly add up the more high quality parts you want to use like linear bearings and ballnut leadscrew and nuts.

I remember something regarding the thousands of steps..... Did you check you're microstepping settings on your controller? That might be the base of your problem. :)

Disable microsteps with the other lead screws. Also use a higher voltage with the steppers.

I am using this spindle on an MP-CNC (quite a bit bigger than the Dremel CNC) and I can really use the full potential of this spindle, which is quite good for the price ! It had a big tendency to overheat though, so building a water cooling sleeve is definitly a game changing upgrade !

THANK YOU .

Suggestion put the CNC on soft plastic foam board (similar to packing used to ship 3D printers and Desktop CNCs) That should kill the high speed noise. Maybe 40-50 Durometer rubber would work.

When cutting MDF or laminate wood a up/down cut router bit will give you the best results and little to no burr.

Well now you can at least mill the parts for the new machine :)

What program do you use to make the Gcode? It looks like the Fusion 360 Do you have the configuration you use to use with the GRBL?

No one's mentioned emissivity yet? :P You can't just point an IR thermometer at a reflective surface (such as the aluminium clamp for your spindle) and expect to read anything close to an accurate temperature. In fact, with surfaces as reflective as aluminium, you're mostly going to be seeing the temperature of whatever's reflected in it! (eg yourself, the rest of the room, etc.) Those thermometers only give accurate readings from totally matte black surfaces (but anything that isn't shiny will be fairly accurate). Btw, you can get more powerful NEMA 17 stepper motors than the ones you're using there - you don't necessarily have to jump up to NEMA 23 :) E3D have a number of different NEMA 17 motors, including their "Super Whopper" motor. I don't know how easy it is to find those on AliExpress, though...

Could you use this machine to CNC aluminum parts to make the bigger more powerful machine you mention towards the end?

Your Dremel cnc machine is a nice one, stick to it. I would like to comment on your use of a 500 watt spindle. - Lowering spindle RPM with the same feeding speed is increases (not decreasing) the cutting forces dramatically - Seen the wood chips and burrs your guiding rods are bending (vibrating). Be careful here, if rods are coming in own frequency, bad things do happen - When using heavier spindles please consider THK or similar linear guides on a solid base Good luck Nice job so far

Hello, have you meassured how powerful the spindle and/or the power supply are? Are they really 500W?

Отличное видео! Рукастые-головастые ещё не перевелись

Alright bro.. I'm about to embark on my own CNC build this Xmas while I have time off work but I'm not very electronics savvy so I was wondering if u could let me know what the best controller would be to get for my Nema 23 motors and TB6600 Drivers? I was told I could use an Arduino Uno R3 controller for this but I'm as dumb as a bag of hammers when it comes to this stuff. I've got my Aluminium 2020, 2060 & 2080 1000mm lengths ready along with other parts to build the frame. I got a Z Axis which is made from ABS? I believe and it is heavy as hell with a Nema 42 to control the movements.. I was thinking of changing it out for a Nema 17 but I'm not sure.. I'm using belts(2mm) and pulleys but I bought 4 Nema 23's with TB6600 drivers and I got a CNC Shield with it also with 4 Limits switches as well. It was a kit I got for under 100 Euros bro.. It was a decent deal I thought but I'm not sure tbh.. What is the best software to use with the Arduino if I choose to go that route?? Do u have any helpful hints and tips for me before I get to it? I would very much appreciate any advice u can give me bro.. Take it ewasy and keep up the great work. Oh Yeah I have 3 motors. I bought a Topshak 800W palm Router but it's very heavey and I don't want to unbalance the frame tbf so I went ahead and bought 2 other Spindle motors. One is a Genmitsu GS-775 but I cannot find the output in watts of this motor. Does anybody know that answer for me please. It's a 24V motor. I also got the same 500W spindle motor u have here too and it comes with the same 52mm Clamp/holder and I got the power supply with it as well. I also got a 600W and a 360W and a 120W power supply as well.. I have a tonne of gear to begin my build but I really am stuck as far as the electronics are concerned. Any help anybody in the comments could give me would be awesome guys so just in case u help me I wanna say thankyou in advance.. Much appreciated

Hi Nikodem! Would it be possible to change the 3d parts for the nema 17 to be able to use nema 23? I really like this project and I would like to build it. Thank you very much! Best regards from Germany

Good video

Suggestion for heat removal, make some small fins to clamp to spindle motor body to shunt more heat away. :-))

Looks identical to the spindle I bought, there is about a 4mm hole in the top under the black fan, that hole will allow dust particles in and will seize the lower bearing in a relativly short period of time.

Can I suggest using a motor heatsink, so you don't have to worry about melting the parts?

Has you some problema of interference of spindle? When I turn on the spindle, my stepper motors go crasy.

He already did, notice the little Z-axis touchplate he made from a regular PCB. He has a video on that which should explain the process nicely and show you how you can make that handy and cheap touchplate yourself. In short you just use a few crocodile clamps, one on the workpiece (if it is electrically conductive you don't need a touchplate) and one on the tool. The tool is lowered slowly down and when it touches the workpiece (or touchplate) it closes the circuit which the CNC controller can detect (just like it would for a limit switch). If you used the touchplate then you know that the tool when it made contact was 1.x mm over the workpiece (however thick the touchplate is), if you did not use a touchplate then when the tool touched it was at 0 mm above the workpiece.

If u go down with the voltage the amperse increase and so will your temperature. Normaly it should be better to drive with more Voltage and lower Amperes to get lower Temps, it depends also on the data of your used tools. So first you should educate yourself a bit about Electronics and reread the datasheets of your Tools.

What is the end mill name you use to cut aluminum. Can you share a link?

Bro you have talent and I really think that you love what are you doing, but KZread algorithm is bad

I've been wanting to experiment with 3d printed parts filled with epoxy granite. That would increase the amount of stiffness and vibration dampening exponentially. Perhaps even 3d printed parts simply wrapped in carbon tow on key areas, or perhaps even full layup.
