Hello, could you help me? I can't get the control to connect with the esp32. I bought the control that you recommended. I put the mac of the control in the code and uploaded it to the esp32 and when I turned on the control, the LEDs flashed for 3 seconds and turned off and none of them turned on. in no number and when I check it does not seem to connect, can you tell me that I am misusing IDE Arduino 2.3.4 library esp32 3.1.0 Ps3Controller 1.1.0 FastAccelStepper 0.31.4 help friend please help I have been trying to make it work for almost a year and looking for solutions

Very neat wiring. You seem to know all this stuff cold; perhaps you can answer this: About the seperate endstops and "auto-squaring"... What are your thoughts of a CNC where the y-rails are parallel but might even be slightly different lengths and the positions of the endstops are careless (portable CNC, fast setup) - is there a way in g-code to test the limits of the hardware using the endstops, and mathematically calculate the 'resultant parallelogram' and set the 'back-offs' from the endstops to square the 'homed' gantry to one of the y-rails?! Or is this automatic these days on machines?? (I always thought the gatry has to be set dead square and then adjust the endstops to suit... At least, can you direct me to an explanation/tutorial for dual y-rail endstops? (Obviously, they have to 'home' at somewhat the same time and speed or the gantry will rip off..! Right?)

Good stuff! Could you please tell me, how much pressure from the oil pump?

only comment is its better to clock to a fixed point on the table rather than sweep across. usually a ball. no guarantee that table top is parallel/square to slideways. yes, its a bit more tedious as you gotta twiddle handles...

This is also how people think CNC programming works.

Hahahah awesome

orange peel oh noh I was just going to buy this one, thanks for your advice

Wow you got a much higher price than i did, i have ordered everything to convert my cr10 max to core xy and i ended up under 500$ (i got the max for free)

did you use the original steppper motors?

Fantastic video

you build this not for cost effectivness or speed. This build is form of saying thank you to your first printer

you have done an excellent job! Is there a guide to follow for create a lighter version in order to host a fiber laser unit?

The audio fan test in the beginning had me rolling on the floor! I can relate all too well!!

hey Christoph Lehner i have an ender 3 v2 but i am experencies isssues with it it doesn't work good and the prints quality arent that good maybe if possible could we work this out together if possible? id like to get a respond

Hey bro, You make great videos, great production, great craftsmanship overall. I need an advice. An Emco 2nd owner, with a milling tower with some accessories....state of the machine 6.5 / 10...is it worth 5K€? Kind regards.

Really nice.

Looks good but did you show the gate opening / closing? I just saw it in shut position.

Resonate? Vibrations? For a Chinese mini-mill? You're polishing cannonballs, son.

What toolhead did you use for the hotend?

Nice rolling tray

this takes 'DIY it instead of buy it for 3x the time and money' and turn it up to 11. Incredible

That's not that expensive for a modified printer 😂 My ender 3 is worth 1150$ and that's nothing in comparison to what others have done. I tried to make it the cheapest possible way, I bought it used and I don't even have pressure advance on it or a modified movement mechanism. I bought 3 CHT nozzles (0.4, 0.8 and 1.2mm) and 2 bimetal CHT abrasion resistant nozzles (0.6 and 1mm), high temp direct extruder, new motherboard, new print bed, new print bend tensioners, modified motherboard cooling system and some other gadgets

Good job

Finally managed to start the slider as someone who has no idea about electronics and side topics. For now I am mastering the PS3 controller, it is a pity that Hal sensors are not supported, I have to find a willing friend who will add the code. I used 3 x engine amazon search B07KZQ77VH Model number 17HS15-1504S-X1 ESP32 board amazon search B08BTS62L7 Model name ESP32 Board Dev Kit C V4 Board 3 x TMC2208 aliexpress search 1005006416689175 Now a few topics I had to go through as an inexperienced person. 1. ESP32 board Bluetooth MAC address. I got this address in Arduino IDE File->Examples->ESP32->MacAddress->GetMacAddress (if you don't have ESP32, you need to install support for this board) after uploading the code, run Narrędzia->Serial Port Monitor, then press the EN button on the ESP32 board and the ESP32 board's Bluetooth MAC Address should appear, which we need to note down. I managed to do this on a laptop with WIN10, but on a desktop computer with WIN11, errors appeared when uploading the code. 2. Then, you need to save this Mac Address in the PS3 pad, we do this via the Sixaxis Pair Tool application (available on the Internet) and connect it to the computer with a USB cable. 3. We need to change the Mac Address in the ESP32_3AxisCameraSlider_Code-> src-> main.cpp file in line ~464 [ Ps3.begin("20:c9:d0:d5:92:3c"); ] 4. The next step is to install Visual Studio Code and then PlatformIO 5. Now we open the platformio.ini file from the ESP32_3AxisCameraSlider_Code folder in Visual Studio Code, it takes a while because the necessary components are downloaded, we save the project so that they update, I have paths, we close Visual Studio Code and run it again, we open the platformio.ini file, after that we should upload the code to the connected ESP32 board and everything should be ok, it wasn't ok for me, there were errors in both libraries, I finished Visual Studio Code. What I did was download new libraries from gitchub.com ( FastAccelStepper , PS3 Controller Host and overwrote them to the ESP32_3AxisCameraSlider_Code-> .pio-> libdeps-> esp32dev-> folder) 6. After opening platformio.ini and uploading the code to the ESP32 board, there were no more errors and everything started working. 7. You still need to pair the PS3 pad with the ESP32 board to which we supply power, e.g. from USB, press the middle button on the pad with the logo, four diodes on the pad light up and after a while one diode lights up, which means connection to the ESP32 board (in my case, diode 1). I checked it with the original PS3 pad on which there was a sticker N1158 (the pad has a worn right analog joystick and the engine can sometimes spin slowly) and with the Esperanza EGG109k replacement, in both cases it works.

After this, it's not Ender 3 anymore it's Ender 3 promax. Good job and thumbs up for your build.

Very cool! Thank you. How do I find the files in Makerworld? I searched moon, moon lamp and your name. Can you help please

Could this melt steel beams running on jet fuel? Have a bet with a friend.

It's not just about saving time, it's also about eliminating potential for human error. One screw-up and you gotta scrap the workpiece and start over

What a waste of money. For that price you could make really needed upgrades, like lightwell aluminum milled gantry for hotbed, good cooling etc.

Damn that's cool

Thank You! Saved me from throwing my money away ..even for used .

I printed it, it is amazing thank you for sharing!

Couple of nice moon shaped popcorn bowls

Tooooning

Hi Christoph, kann man irgendwie mit dir in Kontakt treten? Per email vielleicht? Lg Roland

At least pla is super cheap and can be reused.

No one thinks that

FSM strikes again!

Be nice if you could actually run all these tests, but usually you can’t.

Hi mate I recently upgraded my old Tevo tarantula i3, with a new Octopus 1.1, raspberry pi 4, with a 5” touchscreen, and 24 volt power supply, and upgraded the frame, and a modular hot end, in aluminium, so I can swop out a single to dual extrusion, and one good thing it’s so quiet

Can you guide should we use polymaker shining machine ?

Good afternoon! I want to build a CNC machine, and your CNC machine design has piqued my interest. However, I have a question. My question concerns the frame construction. As far as I understand, the frame of this machine is made of square tubing. In this design, the square tubes are stacked on top of each other and connected with bolts, if I understood correctly. Could you please tell me if it is necessary to process the parts of the square tubes that are stacked on top of each other in order to avoid deviations from the flatness of the entire structure? Or is the manufacturing precision of these tubes already sufficient for building such a machine? Or should I choose specific tubes that are manufactured with special tolerances? What would you recommend? Thank you in advance!

Finally I've found more people like me!!! 😭❤ The printers projects never end!! 😂 Great video, great community!!

Cristoph, I know I am a bit late to the show, however, I must say your idea is perfect and I might adapt it to my round column Enco mill/drill zx7045. During the process I have been entertaining thoughts of up dating the round column to a square column such as the Optimum offers. Do you think the Optimum column if ordered thru Optimum I could change to the square column with minimal assembly effort?

brilhant jobs

same set up i need build my new vevor 2.2KW spindle and VFD but i not understand how i connect pump start same time than spindle, BUT stop different time than spindle, i mean if stop spindle water pump stay run and after 5-10 minute later stop. can this add to VFD data pin AL1 or DL1 or TB relay out pin and program VFD control pump ??? i have VFD CV100-2.2S and how i connect linuxcnc-breakoutboard relay to start/stop switch. potentiometer i understand connect to Gnd-AL1-plus10V. i NOT understand external switch on/off were connect, DL1 ?- Ground maybe. and were pump DL1-gnd or TA relay to TB pin ???

Would this work on a 2000 lb 9ft long cast iron lathe from around 1915? I have to get this thing raised about 8 inches somehow, and it's huge...

Superb video which I'd recommend to anyone starting out with a metal lathe.

The drawbar on my Quantum/Optimum BF16 Vario already have this built in. I never hit the drawbar with anything, I don't like to smash anything at my machine. It makes me wonder if the bigger machines like the MB4 doesn't have that. Thanks for the video, it gives food for thought.
