As you've just discovered the exciting way, components that look "low voltage" sometimes aren't. The display stopping the machine from working may have been shunting a control power supply. First suspect for those little fork encoders is dirt on the surface. The emitter and sensor are often firing through small holes, so a bit of grime can have weird effects like only detecting some of the slots.

The display is using 5V (system power supply), just as the potentiometer does. Pull them to ground and the system won't start up.
@eelcogg 2 жыл бұрын
Late to the party but yup, just because it is 5 volts doesn't mean it is isolated from the mains. Depending on power supply design, the whole things can be floating on top of the mains voltage. I would have probably made that mistake too though, It is plain evil of them to not insulate the potentiometer terminals if they are indeed connected to mains somehow. I would love to see what's underneath all that potting on the driver board.

I have to tell you… I’ve been a fan of your channel for quite awhile now and have recently been binge watching your episodes. But this one in particular strikes to the heart of who I am. I am an electrician who has for the better part of 30 years fixed other peoples screwups. This episode is my life… so many times I’ve said that designers, manufacturers and most of all engineers should have to repair the things they design so they know the real world impact if the decisions they make on the drafting table. I have sediment pieces of equipment and I always think… “what if I had to replace this part”… or that part or remove that screw. Love this episode and live the channel!! Well done from a fellow resident of the empire of dirt slightly to the west. 🙏🏻☺️

6:18 most likely that they are using the potenciometer as a adjustable voltage divider. So the resistance is totally arbitrary. As long you don't go crazy like putting in a 1 Ohm pot, that would load the power rail to much or 10 MOhm that would be susceptible to noise injection and unwanted loading of the set voltage.
@Blondihacks 4 жыл бұрын
It may also be part of an RC circuit, though, in which case the total resistance matters quite a bit.
@markoantesic4362 4 жыл бұрын
@@BlondihacksI don't know, but you can check. :) Measure the voltage on the potenciometers outer 2 connections. I would expect 5V or 12V or something like that - a stable supply voltage. Find the ground and measure the voltage on the middle pin. In these Chinese electronics, you never know - might be tuning a oscillator for the main uP for what we know :D.

This looks like a low-end VFD slightly adapted for this machine. Their analog control inputs are generally 0-10 V and the 10 V (sometimes 5 V) reference is made available on the control terminals. The control I/Os are often just GPIOs of an MCU, so pretty high impedance.
@glenntrewitt 4 жыл бұрын
My guess is that the center terminal goes straight into a microcontroller's analog input - high impedance, and you're done.

I am with@@glenntrewitt on this one. My guess is that the actual resistance of the pot is damn near irrelevant (beyond the super loose constraints mentioned by Marko). Still, you'd think they'd decide on a standard pot. Fascinating.

The similar style Grizzly mill I had blew a board (one of three I think it was) and their Support just threw parts at it until we got the problem addressed. Then the Precision Matthews 3/4 B-port clone mill I got to replace it had a tight collet key in the quill, and I wrecked the nut not realizing it had reverse-threads. Matt had a replacement shipped for free from Taiwan even after I admitted fault. The key was retained with a double setscrew, so this video had it all going on for me. I'm presently looking at selling my Atlas lathe to replace with a Precision Matthews, so I'm glad to see they are still service-oriented.

Since that time the mill rans without any problem and has much more torque to the shaft and is much more quiet. But go ahead like this, it's a great job.

My tip on electrical connector removal. I have worked on laser printers which have many connectors on various boards I would use a number of felt tip various color markers. I would start with a single colored line on the male and female connector, then go to two lines (3 lines, etc.) on the next connector and change colors as needed until all connectors were marked. This has made reinstallation much easier.

I have to say that customer service at Precision Matthews is top notch. I bought a mill from them about 1-1/2 yrs ago. Got it all set up and tried to install the R-8 chuck into the quill, but the draw bar would not engage into the threads of the chuck. After a lot of inspection, it became obvious that the hole in the quill for the draw bar was drilled off center at the bottom. I contacted Precision Matthews and they immediately set things in motion to help me. They contacted the factory which requested that I take some critical dimensions for them so that they could remanufacture it and hone it to the dimensions of the machine. Regrettably, it took some time to get the new quill, but it fit great and all was well. I really love my PM mill. Very handy for a home shop.

Hi Quinn. I'd like to suggest upgrading the machine with a VFD. You'll be able to go from 0 to 6000 rpm (or whatever your spindle bearings limit is) without ever changing pulley ratios, get vector control and adjustable torque limit, and control over the acceleration/deceleration and reverse the direction of the spindle, making tapping with the quill quite a viable option. You could even add a shaft encoder for closed loop position and velocity control. I'm not sure if your spindle motor can be driven by a VFD (some can handle permanent magnet synchronous motors), but even replacing the motor shouldn't be too bad cost wise, and could be an interesting project for many home shop milling machine users.

Glad you got it fixed. I have to share my experiences with the same Mill. Just for comedic enjoyment and commiseration. I had every single one of the problems you did when my motor went out. Every single one. Except, I also had the following extra fun additional problems. 1. My replacement motor had a 12mm shaft, where my older motor had a 10mm shaft. 2. No new Pulley included. Had to bore out the old pulley, and re cut a new keyway (at least I could align the keyway with the setscrews this way!) 3. The new circuit board did not fit my enclosure.. requiring a whole new enclosure assembly. And $500 for the pleasure since i was out of warranty. 4. My speed replacement speed control was a completely different type, using magnetics instead of optics. I still haven't gotten this working (mostly out of frustration). Anyway, good video, just had to share. I laughed at each step. B

Wow- even more parts variation than I imagined possible. These machines are an adventure.

Just a thought...but you should sweep up all those copper chips and then make a cheap homemade forge (like a king of random style forge if you don’t have a forge) so you could easily melt that copper back into a small ingot for later use. I did that with the chips from my copper lap project and it worked great. Ps. Might be a cool video idea.

God Bless You, you're very patient. Rather than buying the nice new mill you bought, I bought a 50 year old Bridgeport from a shop that was going CNC. Ending up replacing the motor, but otherwise no probs.....yet. My baby is plenty worn, so no ultra precision, but she's comfortable and works just fine. $1200 Texas surplus prices.

For anybody who has never messed with electronics the covers on electrical devices is there for the purpose of hold the smoke in. Back when I was running CNC equipment in our Tool Room we had a 1980s Slant Bed CNC lathe fitted with a new Fanuc control. Everything thing was working great. Now the new controls input and display was put into the old control panel on the sliding door. One day I'm running a job with multiple parts and there's drill about 4 inches deep in the part and the X axis tries to home and index at the same time. The Machine sounded like that old joke dash plate for German cars. The one that mentioned krashen bangs und spitzensparken. Turned out that the was a small chip of metal that was hanging on a screw that fell off and caused all the trouble by falling on some contacts.

Wow, that was a horror story.you have the patience of a watchmaker and the calm resolve of determination to get the job done. I've learned over the years to not get overly upset on these things mainly because I've never seen a machine respond positively to anger. Glad to see you kept your sense of humor during the process, good program as always Quin thanks.

Wow poor girl, reminds me of why I no longer work as an industrial electrician. Your motor probably burnt out because the cooling fan speed was a bit low for the amount of current you were drawing or it could be that the dust cover itself was preventing fresh air from passing over the motor. I would recommend that you install an electric extraction fan for cooling on your dust cover and make sure that fresh air can get in.

Thank you Blondie for your vids. As a machinist, a few years ago I was hired by a U.S. company to fix the problems that their Chinese manufacturers had created with machined parts. It was 1200 units with more units waiting to be manufactured. It was apparent that each batch of the product had different dimensions, threads and screws that were in conflict with the original drawings. That all created a problem with parts from another manufacturer that were supposed to mate up. I reported the issues to the company who hired a representative to meet with the Chinese manufacturer. The short explanation is that the parts were manufactured different depending on the day of the week and the shift. If they ran out of imperial screws, they randomly replaced them with similar sized metric screws / threads to match whatever screws they had laying around. Maddening! I mention this because it seems Precision Matthews is having the same issue with trying to get the Chinese manufacturer to supply the originally engineered electrical parts. Cheers-

At 5:18 you said "there's a little nut holding it on the front". It reminded me of when I recently took my car to a mechanic, and I overheard him telling the supervisor that the only problem with that car is there's a loose nut behind the wheel. This is the first I've seen of the fuel-hose/grommet trick. Great video, keep up the good work.

I have solved the mystery of the spare screw, its mine, My mill was missing 2 screws on arrival so someone else has a spare screw rolling about somewhere. The rubber gloves you usually use might of saved you the tickle you got. Thanks for sharing your ordeal and i'm pleased its fixed(we can now get some more milling videos) I noticed your first controler was a 220v converted over to 110v by simply using a sharpie 😂😂 Its amazing what people in china can invent. Mine is 220v too. A great video.

Really gives one an appreciation for a three phase induction motor / drum switch / step pulley arrangement. I hope my Guandong VFD holds together, but if not, at least it can be jumpered out to bypass. But good to know that the control circuit might be putting high voltage out to the potentiometer!

I realize this is an older video, but here's a neat little trick for routing wires around corners. You had the right idea with the string, but next time try using a vacuum cleaner to suck the string through some mazes. It works well when running network wiring through some tubes, but it also works well in some other tight spaces.
