Thanks, Lanierje. After a year of busy work & frustration. I finally made it worked. Problem was controller on prover had defect & Sainsmart graciously replaced free of charge. I am thrilled & thankful for your video.
Thinking of entering the world of CNC. Looking at future upgrades after learning for operate CNCs. Just retired and getting my woodshop up and running. My wife is a crafter and the CNC will help me help her. This video will help me when I will need to upgrade to a more powerful spindle. Thanks for the circuit diagram. (I'm a retired electrical designer)
I liked the video but did confuse the power supply with the 100v one by watching the video only. I luckily happen to be on my computer rather than the tv and looked at the comments. Please try to add your advice to the video. i wondered why you were "brave" enough to touch a non-earthed mains casing whilst the power supply was on. Similarly it is easy to miss that it is a 48v spindle.
1/4 watt is fine. The actual power dissipated in the resistor is about .025 watts. So use any size that is physically convenient to work with. Also try this video I just made ua-cam.com/video/svj7zPuYvos/v-deo.html This video shows some wiring diagrams.
I know this an old video but recently purchased a 3018 prover V2 and upgraded the spindle as you did and trying to wire as you did. On the new main board I don’t have the 0-5 v plug as yours does. Can I not plug that plug into the spindle plug?
Hey, thank you kindly for this video. Saved me some headache as I had bought a similar setup (brushless 500w), with the same power supply, and was wondering how to wire it to my GRBL -- I notice you don't have Ground connected in the video, but you do in the diagram. I assume using the GND is a good idea, so long as the GRBL board and the 500W power supply share the same ground at the wall. I get a bit nervous when dealing with mains, but I guess if something starts to smoke, I did something wrong.
this is great information, thank you, question about the pull up resistor, how do you figure out the size needed, my power supply say 0-10V and you said yours is 5V,
I was able to find all the connectors except the 2 pin plug that you used to get the 5 volts to up the voltage with the pullup resistor. What is the proper name and where did you acquire it. Thanks Jon
Have a question, where I live all the electronics stores have went out of business so I'm at a loss where to get some parts as well don't know what to call them. First you made a new 3-wire plug for the connector on the power supply, what is it called and where can I order it. Second, You added the 100k resistor and plug it into the 5v that was on the mother board, what is the connector called. Third, I have the original wire that connected to the spindle motor but it's too short, can I use the Anderson connector to lengthen the wire or should I get a new one, what's it called. Know this must sound crazy but because of Corvid everything closed up. Your help is apricated.
THANKS for your great vídeo!! I have a good question : I got a 3018plus 500w...and the PSU that came along with this cnc kit seems too weak maybe or ITS getting too noise at the system since one minut of milling causes complet freezing the steepers get freezing and ... Assuming i could take another DC 24v 5a Power Through Jack , can i keep the 48v10a PSU at the board ? Or It MUST be Wired separetadly ? A board can get Burnt with this both PSU adding voltage? can i minimize RISKS by lowering down main PSU voltage for 24V20a and plug another 24v5a Through Jack ??
Thanks for the great video. Way better solution than most others one can find on YT. A question, I recreated your setup exactly, also using the 10k resistor. However if I run the spindle at max, the output voltage reads 52, not just 50.7 as in your case. Maybe I am missunderstanding something fundamentally but since the PSU is for max 48 and so is the spindle, is that an issue?
@@lanierje ha, I knew I missed something, thx! ;) . Btw, I omitted the entire SLR on/off controll and do everything just through the PWM of my 3018 board, works flawlessly.
I suppose it was a mistake to buy the 500w spindle with the operating voltage of 100VDC. It comes with one of those cheap p/s with an output voltage of 0-100VDC. I can't find anything on Amazon with 100VDC output. Will the p/s your using work with my motor with only a 48VDC output? I'm guessing no. But, I don't know. (Motor has operating voltage of 100VDC at 4A. Input AC110V +/- 10%50/60hz.) If anyone can clue me in, I'd be grateful. I've got everything in the video but the better power supply. Hope I don't have to buy another spindle motor. :/
I have one as well and it doesn't make sense out how is the spindle 500w when the power supply is only able to deliver 480w including feeding the machine stepper drivers and board.
It isn't powering the steppers or anything else. It only powers the stepper motor. Also, the motor is rated for 500w but it would only approach that under heavy loading if at all. The motor uses a tiny fraction of that power under light loads. The 10A supply is plenty big for this.
It is not better to switch on the DC side for the spindle ? Thats what I did using a self made mosfet switch unit so that I can use the PWM spindle output.
@@nicholaswouters1203 You need to filter it in some cases if the gate capacitance isn't high enough. A .5uf across the gate is plenty. An RC filter would be slightly better as is in my diagram. Also, PWM amplitude is constant, only duty cycle changes. It is conceivable that a rectifier to the gate would also work well. The triac switching would still occur even at very low duty cycles. Thanks for watching.
Some time ago I did the update with a 500w spindle and 100V source with manual speed control. In order not to buy another motor, can I use a similar power supply ?: Output voltage range: 0-120V continuously adjustable, output current: 4A, adjustable to 122V, if possible which solid state relay would you recommend?
IMHO I think you are fine. The weight should not be much of a factor. Just keep the plunge step low for difficult materials so that it doesnt require much force. Thanks for watching.
Hey! Thanks for the great videos. I have almost the same set up now but my rheostat looks different and obviously is a different pin out. I have a red black yellow in that order if I connect either + or - to the black middle I get 24v. Then I’m left where to connect ground. Red shorts out yellow jumps it to 72v. Lol I’m pretty mechanical but this stumps me. Any help would be great
You do not have the right power supply. If you have one of those 100v power supplies they are dangerous and not isolated from the mains. Don't do it. This method will not work on those!
@@lanierje it’s a Dork 0-48v 480 watt power supply. I bought from Amazon using your link. Should have a commission on that btw. I also bought the relay from your link and found resistors. It’s wired as yours with exception of in your video it didn’t go into how to tell which pin out on board and I’m assuming (great word) we have diff. Controller boards. Mine is a generic with no cnt out bit a generic 5v next to the 3 stops plug ins. If I had an email or something I could send pics. My gues is the controller. Going to buy when I find which one and which pin out
Anderson Powerpoles have ratings of 15,30,45. All Powerpole contacts are the same as I recall. They are sized for different size cable to crimp. So any of those will do. Thanks for watching.
@@magnus800 It is compatible. The power supply has a 110/220 switch on it. Be sure to connect the GND terminal as shown in the circuit diagram link for safety. In my video I am using a temporary connection to the mains but you need the GND for safety. The GND is connected to the case of the power supply and the V- is isolated.
Do you have links for the filters and resistors. I’ve ordered a lot of wrong parts in the past and I’d like to save a trip to the electronics store to look like an idiot lol
48v × 10amps = 480w so thays fine... What about using 80v ×6amps = 480w Whats the difference in preformance.. You're still 20watts under its rated and 20watts under the OEM power supply. I assume with 48v and more amps it runs slower than 12k rpm but has a higher torque The OEM is 0-100v at 5amps. Voltage is usually attributed to speed and amps is torque 🙃 It would be cool to get you to do an experiment with the different supplies to see what the difference in preformance really is. I'd like to see the rpm of your spindle tbh. Also why did you jump 100k ohm resistor to the 50v output ?? Like thays doenst make sense. You're pulling up to 50v through 100k resistor.... what in the hell ?
New to this stuff and wrestling with getting the right kind of JST connectors. Could you possibly point me in the right direction? Thanks for a very informative video!
As I recall I ordered assortment kits from amazon for JST-XH and JST-VH. You will also need crimpers. I bought the Engineer PA-09 but there are less expensive versions out there.
Hi how are you, May I be allowed to pick your brain please?, 1) my power supply has a different lay out compare to your power supply, 2) power supply has three wires for the rpm controller yellow, black and red, behind that it has a switch to change it from 110v to 240v main, then it has two terminals that are linked called off and on, then two terminals for the spindle then two more terminals for the mains power lead. 3) I have currently connected the mains to 240v and the two next terminal to my 500w spindle 4) I have the same relay as you used. 5) I also have a volt / amp meter I want to wire up as well, which as two leads, a two pin with black and red lead plus a three pin lead which has red, black and yellow 6) I have all different ohm resistors I can use Are you able to do me a simple diagram so I’m able to connect everything up correctly please?

Anyone know of other control boards this would work with? Finding a 3018-Prover board in the UK is proving to be a bit of a pain....
Hi lanierje, lovin how you did this. I want to try it. how is are the components holding up, anything we need to be aware of?
can i use this setup also on my twotrees TTC450?
I don’t know. I am not familiar with that product. Its looks like a nice machine though.
Note: Not all Solid state relais can use pwm..
Be sure you are using the right one.
That is why my diagram has an RC filter. The SSR is then controlled by DC.
