Thanks for your video! I buy yesterday a lathe with this issue and here was the solution!!! I have ajusted the IR and the CL, but wasn't perfect but also adjusting MAX and MIN just make the magic 😉👌 My lathe it's a Einhell Mtb 3000 (01012) from 2004/03. Thanks again 😉👌
I've got one of these lathes. Although DC voltage will work, that circuit is a VFD (Variable frequency drive) The motor is a brushless A/C style motor. In reality it's like a 3-phase motor for more efficiency and those pots vary the individual coils of the motor. From the mosfets on the heat sink you can measure the output on each mosfet and fine tune each pot to get a perfect balance of the voltages on each coil of the motor. But if it works for you don't fix it. A perfectly balanced voltage of each coil will give less hum and a smoother motor experience. These motors are a beefed up similar motor to the more expensive drones with BLDC (Brushless DC motor)
What the man who gave you the suggestion should have told you to use a non-conductive screwdriver. They make plastic screwdrivers for this purpose to eliminate getting an electrical shock or shorting out the board. But I guess you got by.
I have a Holzman ED400FD, and I had the same problem. And thanks to your video I fixed my lathe. I was going nuts and was thinking about buying new parts and all, but with this easy fix it works again.
Hello: Congratulations, that's how followers help, good video. I have a mini-lathe with a controller very similar to yours. The IR setting is made with a consumption meter by adjusting to the power of the motor, example: 700W engine is set "I.R." A +/- 800W. Greetings.
i have an identical mini lathe and have a problem were if i leave the power on but turned the speed all the way down so it stops it would spin up randomly. its pretty dangerous so i turn it off completely when i want to check my part with calipers or do anything with the chuck. I might redesign the PCB at some point because i dont like how it setup. it would be better if the hall effect sensor actually controlled the speed instead of just being a readout. I'll also get rid of the potentiometer an put in a encoder dial. might be cool to have buttons to set the speed as well. heck I could have it use a robo voice to make fun of my work too. ;D it would be a fun project though. also the ground wire is connected by a back plate screw. no one takes the back plate off in a careful way to see it pinched in there.
That does sound dangerous. Not an issue for me since I always turn it off anyway. Not sure if I've mentioned it before, but even though it is a MINI lathe, I'm pretty sure this is the most dangerous thing I have ever purchased. I'm very, very careful around it. I watched some videos of REAL lathe accidents and they are horrific. Anyway, I like your encoder idea. If you do it, you should post it up and leave a link so I can go see it. Good luck!
You can hear it at 4:43. Did you watch the whole video? I think the machine is not supposed to stop when the pot is turned all the way down. It's just a speed control. Turn it off to stop it.
I have the same lathe, and when I took off the speed control board cover I also noticed the dangling ground wire. I was told when you buy these lathes the first thing you do is disassemble them and I am glad I did because the amount of factory grit and grime everywhere and old thick oil on everything. Even my headstock bearings were hard to turn, took it apart as well cleaned everything good, and repacked them with quality white lithium grease, now it purrs like a kitten. I also built and installed new carriage gibs, the ones that come on it were riding the bed at an angle (not good), so now with the wider thicker gibs running true and flat it's an awesome little lathe. Oh yea anyway the ground wire, when I got close to full disassembly of the lathe I got to the motor and on the side has a screw hole for a ground wire which was clearly marked with a large arrow, but no ground wire was screwed into it, and the short floating ground wire we each found does not reach that far, so I too hooked the earth ground to the chassis, but it has always been in the back of my mind every time I fire it up......thanks for the video
yeah the ground wire is just pinched between the back plate and lathe by a screw as he suspected its not just dangling out of factory. no one takes the plate off carefully enough to notice it. because you dont expect it.
Hi great instruction video, I have a bernado hobby lathe and I'm using it for making wooden pens ,if I turn 5 or 6 pens and turn the lathe off...it won't start again....it can be up to 5 days and bingo it works again 😀 its driving me nuts , please help !
I'm sorry, I'm not much of an expert on these things. But I have two suggestions. One, some motors have what is called a start capacitor. Not sure if a lathe does or not, but I had a drill press that did that. When you turn it on and it doesn't move, try to get it started by hand. If you just have to give it a little push to get it going, it's probably the start capacitor. Two, try going to www.olduhfguy.com. He's the real expert. Hope this helps.
I just received my mx210v and I watched your vid only difference is mine doesn’t surge it runs about 30 sec then cuts off. I can restart it right away but then it acts crazy. You got any suggestions. Thanks for any input you can give me.
Sorry, I really don't know, but the site I put in the description should help. If you don't see a link check out both videos, the problem and the solution. Good luck.
Yes I would because it gives me a capability I didn't have and I make a lot of stuff. Now that it works right and it really wasn't that much work, I use it for all kinds of things and I haven't really needed a larger one. But I should warn you that there are a lot of extra pieces to buy.
Did you make sure you shut the protective shield? If the shield is up, you have to hold the button to get it to turn. But if you shut it, it will continue to turn. It's their way of getting you to put the shield down.
I'm sorry. I had to translate this online. My French is rusty (by that, I mean I don't speak any French). It translated as Rotary Inverter. I don't know what that is. I think it may be the board. I recommend going to www.olduhfguy.com to see if there is any help on that website. The guy is pretty helpful. Thank you for watching.

those pots are plastic. :)
Don’t worry, they shoved a loose grounding wire into the case
@@yomama5785 At least your safe unless you just slip up. Plastic is always safer.

Really glad I could help. Enjoy your lathe.

Thanks for posting the video it seems the electronics are a weakness in the mini lathes that can be difficult and expensive to cure
Thanks for this vid!

I never heard what problem you were having. Mine wont completely stop running when the pot is turned all the way down.
You can hear it at 4:43. Did you watch the whole video?
I think the machine is not supposed to stop when the pot is turned all the way down. It's just a speed control. Turn it off to stop it.
My God China ?
Look, just like mine, the fuse is on the neutral side!
LOL. I didn't catch that.
Helped!

i have problem same with...when i cut metal and press in depth..motor slowly and stop working...
If the rpm get down with the load cut, can be that? (Sorry i dont understand very well) cutting aluminum 0.25 i have fall of rpm about 150rpm...

Thanks for the vids. Would you buy this thing over again knowing the work you have to put into it to get it right?
Yes I would because it gives me a capability I didn't have and I make a lot of stuff. Now that it works right and it really wasn't that much work, I use it for all kinds of things and I haven't really needed a larger one. But I should warn you that there are a lot of extra pieces to buy.
I have to hold the green button down to make my lathe turn and that sucks
Did you make sure you shut the protective shield? If the shield is up, you have to hold the button to get it to turn. But if you shut it, it will continue to turn. It's their way of getting you to put the shield down.
Bonjour j’ai besoin de comprendre comment est brancher l’inverseur rotatif
J’ai le même tour que vous et il ne fonctionne pas
Merci de votre réponse

thanks for sharing
Interesting video! Any idea as to what caused this problem? Did the potentiometer just decide to go crazy?
I'm assuming that quality assurance is a bit questionable with cheap Chinese products. Perhaps it was never adjust at the factory at all.
Sometimes small pots slip during shipment. I’ve had this happen with expensive equipment as well.
just a motor, throw the rat nest in garbage:)
