You should calibrate the probe using the 4 grub screws. That makes it much more accurate and if you keep the nut and collet on the probe and put a mark on the spindle to align the probe with the mark, you will get much better runout than what you measured. Sorry to see that you crashed the probe but good to see that this is repairable. To calibrate, turn the probe so that the dial indicator touches where on of the grub screws is, then turn 180 degrees and measure again. Loosen one of the screws a bit and tighten the other one. If the runout gets bigger you obviously have to do this the other way around. You may have to loosen all screws just a tiny bit so the center piece can more around a bit. I normally tighten the screws just finger tight until the probe is almost centered and only the apply a bit more torque on the screws. First on two screws at 0 and 180 degree positions and then the ones on 90 and 270 - repeat in small increments and keep measuring the runout to make some fine adjustments
Yes, that little included allen wrench is to be used for adjustment, to dial it in. I'm curious how well this probe will hold the adjustment once it is dialed in. Many of the lower end probes you can get to within 0.05mm or so, but after a little handling, in a few days, they are way out of concentricity again.
these 4 screws, in my opinion, you should adjust because even on the video you can see that the needle screw does not rotate in the axis, 0.1mm error is a lot.
I haven’t found the procedure, but I did find this video and it’s clear once you se what’s inside. I put it in a tool holder and then into the spindle and indicated it with a 0.0001” indicator. I got lazy in the end, but mine repeats within a couple tenths regardless of orientation so it’s pretty concentric. When you turn a screw, it pulls the stylus toward that screw, so you can adjust them a bit each as you turn the probe until it’s centred. Ronald is correct that it’s very much like adjusting a 4 jaw chuck, you can go back and forth between them until it’s right.
Hey Max, thanks for sharing your experiences with this. I also had a quick look for touch probes, and had the shock of their cost! I'm going to see if I can get hold of one :) Really appreciate your detailed description.
The 3 or 4 screws on the top are to adjust it for runout so in theory the collet don't matter however you would need to put it in the same way every time or just check it every use
Don't be too hard on yourself about your router's accuracy. At 10:35, the entire body of the probe itself can be seen wobbling slightly, while its connection to your spindle is not, so aligning it is worth the effort. Also, I noticed a consequence of having a cable coming out the side of a probe is that it can cause the probe to rotate, as yours did at 20:58. Again, not an issue with your router, but something to consider when using wired probes :)
In case anyone else was interested... The parts of note on the main circuitboard are the LDO (low dropout regulator / voltage regulator) Which is a 78L05 and the MCU (Microcontroller) Which looks to be an FT60F01x by FMD.. a 6pin 8-bit MCU with an internal 16mhz oscillator. I'm unsure as to why it has six pins on the connector..
I have one of these and once zeroed they are extremely good and mine has been rock solid reliable. I have found that to get 1:100 mm accuracy I need to recalibrate it for that use as the collet chuck has some run out. I have brought precision ground collets and nut but it still not absolutely perfect. That said for 99% of my set ups there is no need for such accuracy so I don't bother. Bottom line for the price it is very good and it replaced my Drew probe and in my opinion its far better.
Nive that they send individual proof of calibration. I imagine that if you are using Mach4 for instance, you would go through the probe calibration routine as well for good measure.

Hah, completely agree. I've just completed a granite based CNC router and have never dealt with such high requirements for accuracy in so many places on one project. Using a high quality digital indicator on various points is indeed very sobering... and humbling.

Hi there, would you happen to know the value of the diode labeled as bz (just next to the usb plug) used in this chinese touch probe by any chance? Could it be a SMBJ24A?
Hello! I bought the exact same device. But the Chinese comrades forgot to put the cable (or so I ordered). I can't find the pinout of the connector on the sensor housing anywhere. When you opened it, did you draw a diagram? I will be grateful for the information.
It is basically just a spring loaded brass Pin that is connectet to an io on my cnc board. The moment the tool touches the surface it pulls the pin to GND (Frame, spindle and tool are all connected to GND) and the touch is detected. I made it spring loaded so I have some give, just in case to stop it, but never needed it to be :)

@@MakenModify I'm not talking about tool autochange. I'm talking about that the probe is not attached to the collet, but separately, next to the spindle. on a parallel single rail or rotating arm. so that it can be put in the same working position, and then it is not necessary to change the collets, but only take into account the displacement of the probe relative to the spindle axis.
@@АндрейТиторенко-ю4ф Yea I got that, but that needs a better repeatability than the run out. The probe must be out of the way and be protected from coolend and dirt... and I don't need it on most parts so manuell it is for me. But in general you are right, it could be a way.
Good point. Other then that they are good for a rough estimate (good enough for most hobbyists I guess). Workaround would also be to have fixt reference corner on the machine where you "calibrate" it on every use.
The white plastic? It's just an IKEA cutting board. I drilled and countersunk holes into it, mounted it to the table and faced it with an end mill. Works well for "Super glue and tape work holding"
Since I have no idea what PCB you have I can only offer a general answer: This probe is basically just a switch. The Black wire goes to ground/GND (anywhere on your PCB) the Red wire goes to power (logic power of you PCB [+5V?]) and the Yellow one goes to the switch input. That switch input can be an Endstop pin or a probe bin, depends on you PCB and how you configure it in your software. Hope that helps ;)
Genau die habe ich auch 😀 Wenn man dieses Teil wieder ausspannt, verstellt sich die Einstellung schon während man es aus der Spannzange zieht. Die Konstruktion ist leider so. Es sind ja nur die winzig kleinen Madenschrauben die die Aufnahme halten und wenn man den Taster in die Spannzange rein drückt oder rauszieht, wird Kraft auf diese Einstellung ausgeübt und das Ding verstellt sich wieder. Das kräftigere Spannen der Madenschrauben, verursacht nur die Verrundung des Sechskants und der Schlüssel dreht durch 😀 Das Teil ist eben eine Fehlkonstruktion in meinen Augen, oder man macht sich eben die Arbeit, bei JEDEM Antasten den Taster neu einzustellen ;-) Schade, da das Ding echt super schön aussieht und recht günstig für mich war, bei aliexpress war (knapp 60€) 😞
Mir fällt gerade noch ein, dass man es ja testen könnte, indem man für den Taster eine Extra-Spannzange mit Mutter zulegt und diese dann immer ganz vorsichtig aus der Spindel holt. Wäre evtl. dann eine Möglichkeit, da sich die Einstellung dann nicht verstellen sollte ;-)
@@MrThelooord ich hab das Problem gelöst. Eine ordentliche Spannzange kaufen,mit Loctite 270 auf den Schaft des Tasters kleben. Und dann eine Markierung auf der Spindel anbringen,den Taster immer einigermassen gleich einspannen. Dann ist die Genauigkeit +- 0,005mm
@@fastfred6372 das heisst also, du hast den Taster mit der Spannzange verklebt und benutzt diese Spannzange nur für den Taster, so wie ich sagte? Die Überwurfmutter, zum Spannzangen spannen, ist dann natürlich auch mit dem Gebilde verbunden.
@@MrThelooord genau. Durch eine Verdrehung in der Spannzange wird durch die Länge des Tasters der Rundlauf schlecht. Wenn die Spannzange 0,005 Rundlaufungenauigkeit hat ist das in 50mm Entfernung schnell mal mehr als ein Zehntel. Das obengenannte Prozedere,dann Rundlauf vom Taster justieren und die Wiederholgenauigkeit passt.
Does the signal wire put out a negative current or positive? I just ordered one for my 3040 cnc I'm running a szgh controller and it looks for a ground signal for the probe
There's no point adjusting it unless you have an ATC spindle that grantees the orientation of the tool in the spindle every time it's inserted. With a manual tool change spindle, every time you insert the probe, it's going to be out of calibration in a different direction.
@@mattivirta I'm curious about the thread of the stylus, it says M2.5. But most ruby styluses Iv'e seen use M2, M3 and upwards. Haven't seen the 2.5mm version anywhere.
I don't get why this kind of probe needs power at all. It's a mechanical design. It's hard to tell from the video, but there isn't much on the PCB at all. Would be great if you could provide a close-up image. Sorry for the opportunity of the teardown :)
with electronics, you can make any version of the signal NO or NC, as well as visually see the operation of the probe, which also makes it possible to use it not only on the CNC, but also on manual routers
@@АндрейТиторенко-ю4ф NC->NO conversion is nothing that has to be handled by probe itself. The signal can easily be inverted on the controller side, electronically or in software. The LED could be powered by the signal line. Visually the light could go out instead of turning on. I still don't see a good reason for electronics.
@@tcurdt can be done in different ways, one method does not cancel the others. this probe is one of the cheapest probes to buy, so the presence of electronics only makes it better for this price. my controller has only one input for probes or tool height sensors, so I need to assemble a set of the same type of sensors. for example I want three types of sensor. the first is an aluminum plate for finding zero Z and the angle of the workpiece along the cutter, and it is NO, a probe for more complex positioning, and a tool height sensor for working with several tools on one part. in my case, all of them are NO, and mechanically the first one is only NO, the probe is NC, and the height sensors can be of both options.
@@АндрейТиторенко-ю4ф There are many options indeed. You could just invert the signal also for your setup. That's a BJT and two resistors. This does not have be done inside the probe and then having to have another cable to connect (that can be forgotten). Or the cable to probe could just have 3 wires (similar to other endstops). I say it again: I don't see the need for electronics in there yet. Maybe they are doing some hardware debouncing? That's the only thing I could come up with - and why I am curious what's in there.
plug wiring : (-)(+)(s)(s)(+)(-) my pcb failed after second use. Components: 78L05 (5v reg), J3Y NPN transistor (eq. s8050), red & green LED, 5 resistors, diode, 2 caps and FMD 530krn ( I CAN FIND NO INFORMATION) Any information on FND 530krn or replacement PCB? Email me if want copy schematic.
Hm... Also can't find it. Do you know its function? Maybe it can be replaced with something compatible. Also if possible I would contact the seller, that it broke that quick maybe they replace it
@@MakenModify No response from the seller. My knowledge of electronic is very limited. The 530 chip is 6 pin. pin1 to base NPN, pin 2 - gnd, pin3- led1 pin 4- switch pin1 (switch pin2 ground when closed) , pin 5 - +5v 78L05 and to 330 resistor then both leds, pin 6 -led 2. Hope this sense. Mike
@@mikee8467 oh, sounds like a small microcontroller... Like an ATtiny10 style (there are countless small and cheap Chinese MCUs)... To replace it one would need a pin compatible chip and program it (if its broken). If its buying is not to long ago I was lucky in the past by using aliexpresses support. - Max
Yes. But it was "factory calibrated" so that was something that should be tested. After the crash (after the video) I did zero ot properly using the screws.
@@MakenModify Maybe?? but i have one in a cat 40 and if and when you break a probe you must re zero using the setscrews. it was close but not perfect out of the box and its a Haimer ..
normal touch probe cost less than 100$ i buy my probe 64$ same probe than u have, and better big version about cost 140$ max. but not can use big because have ER 11 spindle maximum can use 8mm collect. and all better need min 10mm collect. but if need only Z tool lenght measure need only 2 wire, alligator clip or magnet, and brass or aluminium plate, thats all. less than 10$ cost all parts- and if need XYZ corner finder you can mill aluminium piece square pocket and then pocket corner round hole, then outside cut piece out of alumin plate square outside cutting. thats all, yotube have many video how do, not need buy probe.
That is absolutely correct. My best guess is that if it would be NC it would always have to stay connected. Because it would trigger as soon as you unplug it.

Mir fällt gerade noch ein, dass man es ja testen könnte, indem man für den Taster eine Extra-Spannzange mit Mutter zulegt und diese dann immer ganz vorsichtig aus der Spindel holt.
Wäre evtl. dann eine Möglichkeit, da sich die Einstellung dann nicht verstellen sollte ;-)
@@MrThelooord ich hab das Problem gelöst.
Eine ordentliche Spannzange kaufen,mit Loctite 270 auf den Schaft des Tasters kleben.
Und dann eine Markierung auf der Spindel anbringen,den Taster immer einigermassen gleich einspannen.
Dann ist die Genauigkeit +- 0,005mm
@@fastfred6372 das heisst also, du hast den Taster mit der Spannzange verklebt und benutzt diese Spannzange nur für den Taster, so wie ich sagte?
Die Überwurfmutter, zum Spannzangen spannen, ist dann natürlich auch mit dem Gebilde verbunden.
@@MrThelooord genau.
Durch eine Verdrehung in der Spannzange wird durch die Länge des Tasters der Rundlauf schlecht.
Wenn die Spannzange 0,005 Rundlaufungenauigkeit hat ist das in 50mm Entfernung schnell mal mehr als ein Zehntel.
Das obengenannte Prozedere,dann Rundlauf vom Taster justieren und die Wiederholgenauigkeit passt.
I want to use 3D probe with Syntec cnc controller
I have no idea about Syntec and can't help you with that. I mean you apparently are the support so I would ask you 😅
Mach 3 controls?
No idea. I use estlcam but see no reason why it would not work.
Do you know if something needs to be set up in the mach? I have an identical one, and I will also need to measure the corner@@MakenModify
has someone the scheme on how to connect
That's why I bought the Normally Closed one, it's a bit more expensive but it should survive my attention disorders ;)
Hehe yea saw that they have them now. They did not exist when I bought mine 😅
Does the signal wire put out a negative current or positive? I just ordered one for my 3040 cnc I'm running a szgh controller and it looks for a ground signal for the probe
It's been a while since i wired it up but I believe it pulls the pin to ground.
why do not you adjust it? you have 4 insex so you can adjust it. Can not just be assembled and believe that it is right from the manufacturer.
yea meanwhile did that ;)
There's no point adjusting it unless you have an ATC spindle that grantees the orientation of the tool in the spindle every time it's inserted. With a manual tool change spindle, every time you insert the probe, it's going to be out of calibration in a different direction.
Today just broke my by same mistake 🤣 definitly need probe presence pin 😅
yea that might be a good idea... at least they are not that expansive 😅
@@MakenModify same probe, pin cost about 4-12$ pcs, many seller have. and if have lathe can made own pin cheapen.
@@mattivirta I'm curious about the thread of the stylus, it says M2.5. But most ruby styluses Iv'e seen use M2, M3 and upwards.
Haven't seen the 2.5mm version anywhere.
I don't get why this kind of probe needs power at all. It's a mechanical design. It's hard to tell from the video, but there isn't much on the PCB at all. Would be great if you could provide a close-up image. Sorry for the opportunity of the teardown :)
you are right it is basically just a switch maybe they needed it to invert the signal. I'll have a look if I have some high res images ;)
with electronics, you can make any version of the signal NO or NC, as well as visually see the operation of the probe, which also makes it possible to use it not only on the CNC, but also on manual routers
@@АндрейТиторенко-ю4ф NC->NO conversion is nothing that has to be handled by probe itself. The signal can easily be inverted on the controller side, electronically or in software. The LED could be powered by the signal line. Visually the light could go out instead of turning on. I still don't see a good reason for electronics.
@@tcurdt can be done in different ways, one method does not cancel the others. this probe is one of the cheapest probes to buy, so the presence of electronics only makes it better for this price.
my controller has only one input for probes or tool height sensors, so I need to assemble a set of the same type of sensors.
for example I want three types of sensor. the first is an aluminum plate for finding zero Z and the angle of the workpiece along the cutter, and it is NO, a probe for more complex positioning, and a tool height sensor for working with several tools on one part. in my case, all of them are NO, and mechanically the first one is only NO, the probe is NC, and the height sensors can be of both options.
@@АндрейТиторенко-ю4ф There are many options indeed. You could just invert the signal also for your setup. That's a BJT and two resistors. This does not have be done inside the probe and then having to have another cable to connect (that can be forgotten). Or the cable to probe could just have 3 wires (similar to other endstops). I say it again: I don't see the need for electronics in there yet. Maybe they are doing some hardware debouncing? That's the only thing I could come up with - and why I am curious what's in there.
plug wiring : (-)(+)(s)(s)(+)(-)
my pcb failed after second use. Components: 78L05 (5v reg), J3Y NPN transistor (eq. s8050), red & green LED, 5 resistors, diode, 2 caps and FMD 530krn ( I CAN FIND NO INFORMATION)
Any information on FND 530krn or replacement PCB?
Email me if want copy schematic.
Hm... Also can't find it. Do you know its function? Maybe it can be replaced with something compatible. Also if possible I would contact the seller, that it broke that quick maybe they replace it
@@MakenModify No response from the seller. My knowledge of electronic is very limited. The 530 chip is 6 pin. pin1 to base NPN, pin 2 - gnd, pin3- led1 pin 4- switch pin1 (switch pin2 ground when closed) , pin 5 - +5v 78L05 and to 330 resistor then both leds, pin 6 -led 2.
Hope this sense. Mike
@@mikee8467 oh, sounds like a small microcontroller... Like an ATtiny10 style (there are countless small and cheap Chinese MCUs)... To replace it one would need a pin compatible chip and program it (if its broken). If its buying is not to long ago I was lucky in the past by using aliexpresses support. - Max
AHAHAAHAH, I skipped to 13:40 )))) Sorry about the crash, mate)
Hehe, that is what time stamps are for 😉
now I just need to find an 6mm r8 tool holder
never mind, just made an adapter for a 3/8 collet
Theres set screws that allow you to ZERO the probe...WOW use the set screws thats why they are there
Yes. But it was "factory calibrated" so that was something that should be tested. After the crash (after the video) I did zero ot properly using the screws.
@@MakenModify Maybe?? but i have one in a cat 40 and if and when you break a probe you must re zero using the setscrews. it was close but not perfect out of the box and its a Haimer ..
normal touch probe cost less than 100$ i buy my probe 64$ same probe than u have, and better big version about cost 140$ max. but not can use big because have ER 11 spindle maximum can use 8mm collect. and all better need min 10mm collect. but if need only Z tool lenght measure need only 2 wire, alligator clip or magnet, and brass or aluminium plate, thats all. less than 10$ cost all parts- and if need XYZ corner finder you can mill aluminium piece square pocket and then pocket corner round hole, then outside cut piece out of alumin plate square outside cutting. thats all, yotube have many video how do, not need buy probe.
This product is 1 dollar on Ali express sold for 79 dollars on amazon. drop shop extortion.
10 microns for about $100? Nice.
you not need worry any expensive if have super expensive and too big spindle cheap mini size cnc frame, haha. too big this mini small mikro table.
I do not understand why it is NO and not NC. With NC this would not have happened.
That is absolutely correct. My best guess is that if it would be NC it would always have to stay connected. Because it would trigger as soon as you unplug it.
@@MakenModify is there a cheap probe that is NC?
@@4x4-l2t if you really want to you can hardware invert the signal with a bit of electronics but I don't really see the point
@@MakenModify I have a normally closed version, model TP06, just trying to work out how to wire mine as mine uses a tool probe which is a normally closed switch
@@MakenModify I assume it only "triggers" when you are running the script looking for it to trigger?
Bummer!
