Have you watched anyone operate a surface grinder? It looks like you're re-inventing grinding without any outside knowledge. Can you even grind 2 surfaces parallel? Do you have a surface plate or the 15-$ indicator required to measure parallel? It's not a surface grinder unless you can grind 2 surfaces parallel within a 1/10th over 2 inches (0.004 mm in 50 mm).

The cantilever of the the motor is a death sentence for this design. Nothing wrong with making things small but you haven't considered the most important points about a surface grinder. The column must be sturdy and capable of moving (z direction) in 0.0001 inch increments. Your motor should not slow down under load. If it does, use a narrow wheel or dress it so only the edge cuts. You've got to grind 5 blocks to have any confidence in a surface grinder, one at each extent of the table and another in the center. They've got to come out the same thickness. Besides the obvious bad design, you've now joined the club of KZbin builders who make something and don't use it because it's just "content", not a usable machine.

You came back! 👍 Nice project

Where did you get this spindle

Can i ask if the 3” tilting rotary table fits in proxxon mf70?

Hi, thanks for experience... Do you know the correct vref for 2209 drivers?

A very good rebuild and modification of the warped table. A sugesstion, or two, if you please! I use several small mills and lathes, Perhaps you may be using too much grease, much less will be cleaner! When I assembled my lathe, from a kit, The instructions for the gibs, was to "lap" them in, to obtain more metal to metal contact, and doing that, less play in the movement! To lap the brass, use a light oil, in America we have 3 in 1 oil, but any oil used on Sewing Machines would be good. Then, with oiled metal, a VERY small amount of "Ajax Cleaning powder" is dusted on the oil, then tigthen the 3 screws, until there is a light FRICTION. Go back and forth, Disassemble, CLEAN metal and see what the oil and powder removed! It will not be much, so REPEAT the oil and powder, assemble it, tighten the screws and the friction, as you slide left to right, right to left, DO that 5 to 10 strokes, left, right is 1, left right again is 2, OK? Take it apart, clean. SEE more metal is gone ! The BRASS METAL, should wear "IN" the pattern and angle of the body, to be CORRECT. Even Better on larger mill with Cast Iron body! X direction, when processed will be more ACCURATE! Then do the Y axis, same procedure. WHEN you are done just use that LIGHT OIL, the grease is to thick, BUT is keeping the PROPER ALLIGNMENT of Gib to Body from being CORRECT! I hope this translates for you, I could understand your translation into ENGLISH, but some words the "translation software" did not do proper terms! I am, philip, from the Great Pacific NorthWET, Oregon Division, USA

I can't get anything to stick to the build plate on the Anycubic I just acquired. What do you use stick glue?

where can i get that tool that you used to pinch the piston with

what cleaning solution do you put in the ultrasonic cleaner

Toy machines, very amusing...🤔😏🇬🇧

Hi Volodymyr. I just ordered my RC8B4.1. I got the e version and yours is the only build series I have found so thank you in advance for your series, it’s greatly appreciated ☺️

Hola, me han regalado ese mismo DRO y me gustaría saber si puedes compartir los archivos para imprimir en 3D. Muchas gracias. He visto que no funciona bien, pero creo que para mis proyectos puede ser suficiente,.

"how to ruin your minimill"

Interesting mod. Did not see this before. What was the reason for it? I have this printer since few weeks and so far with standard set up it printed PLA and some TPU quite fine. I am thinking of doing this mod, too. But my concern when looking at this is that due to smaller radius of the tube there will be more friction to the filament especially for TPU and similar. Do you have clear benefit now after finishing this? A conclusion video would be interesting. Some user commented on his make that v2 version produces squeaking noises on retract. Also I saw your other mods on your Thingiverse profile for this printer. Will come in handy for me, too later on. I'm thinking of adding 3D Touch sensor, too. And also I see you used(d?) another fan duct which cools from both sides. This was my first modification right after buying the (used) printer.

G'day mate. Did you make that motor mounting plate or did you buy it ready made from somewhere? What a great way to increase torque.

I can't believe the balls that little machine has. I have one on order a couple of weeks ago and I'm not sorry now I've done it. I will upgrade the spindle though to ER11. Well done mate.

Elinize sağlık güzel olmuş, fakat bu kadar uğraşmak yerine sonsuz vidanın aynı kalınlığında uzun olanını temin etseydiniz hem yükseklik ayarı orjinal olarak hassas bir biçimde kalırdı, hem de bu kadar kes biç gerek kalmaz işlem kısa sürede tamam olmuş olurdu.

Why is the proxxon spindel not good ; why work the new spindel better?

Amazing vid. Would you able to help me install the BLTouch to my printer? I'm also running Klipper, but I have no idea how to mount it, or configure it within Klipper. I'm also running an SKR 3 EZ board. Thanks buddy,

Не стал брать этот станок лишь только потому, что он в таком виде стоит гораздо дешевле. Очень ненадёжная вещь.

Владимир добрый день Вы занимались доработкой своего токарного станка, добавления цифровых линеек, после установки первого комплекта (DRO LP20E) вы его заменила на другой (YH800-2E), можно узнать причину замены? Я рассматриваю первый комплект к установке на свой токарный мини станок Заранее спасибо Петр

Watch out for grinding dust, that motor is sucking it straight in. fan cooled brushless motors won't survive long, more accurately the esc will fry wheel it goes.

Never cut tube like this, take a charp knif

Sweet, sweet mods, Volodymyr. 👍 Just wondering; if you were asked to apply the same mods and upgrades to our MF70 units for a fee, how much do you think that would roughly run us?

I have been racing rc for a long time and would pay you to make the conversion plate and the torque modification

Very nice work sir

Are you using air filter oil as loctite?

Привет скажите пожалуйста можите отправить силку где купить матор

you will get much better cuts starting from the other y direction ;) also the endmills will last longer

do you this error when finalize a print? !! Must home axis first: 101.480 96.510 20.500 [1566.191]

Not sure if I heard correctly but it sounded like you were reading the runout for the chuck on the indicator as 3/1000 mm but that is actually not what the indicator was showing. Each tick on the indicator means 1/100 and not 1/1000 of a mm. Therefore the runout is ten times higher than what I heard you saying (being three thousandths). Maybe that's just because of incorrect translation, but I can't tell. I hope this was helpful.

Hello, I just started to build my RCB84.1 today. And there are no bladders for the shocks, did these come from in your kit? I received emulsion seal, thanks.

👍👍👍

Good day sir would like to ask if you are selling package spindle upgrade.

I got one exactly like that, the belt is 1.5 x 70 tooth , just in case.

En que material lo realizaste

You are the expert. I wonder... do you think there is any risk or issue running such a large diameter tool on a mill with such small shaft / bearings etc.? I was thinking there may be a reason Proxxon limited the tools to 3mm in diameter? I am genuinely interested because I need something like this for my ff250bl. Nice job!

When locking the tool piece in tighten it anticlockwise, if you read the instructions that's what it advises you to do as it tightens more securely.

Здравствуйте, подскажите пожалуйста, что это за версия станка? Сколько не смотрел в интернете, у всех станков mf70 алюминиевый столик с тонкими стенками и открытыми солазками поперечной подачи. А у вас какая-то другая Конструкция и судя по цвету, столик стальной.

Have you ran it, any updates or videos? Just wating for ya :)

I thought it would choke but managed to cut it. It’s not the stock motor?

I had the same printer and I was never satisfied with it. I modified everything. All fans new and more quiet. All bearings from misumi because after some time they were shaky. Then different hotend (e3d V6 clone) because of continuous under extrusion. Then direct extruder because I could. Then BL Touch because buildplate is not flat. Then vanilla marlin firmware because it's adjustable the way I like it. Then mini 12864 display (without touch) because I have more firmware settings that I can adjust than with the touch display. Then tmc2208 stepper drivers because the original are so loud. Then I changed the board to skr because I wanted 32 bit and marlin 2. And then wanted to get rid of that disgusting metal frame and replaced it with a full bear frame and printed all the bear frame parts and bought missing parts to make it almost like a Prusa. Then I replaced the tmc2208 with tmc2209 so I can have sensorless homing. I also exchanged the power adapter and build my own heatbed with 6 mm aluminium and magnetic build plates. The result is a printer that is better then the Prusa mk 3s+ and even has input shaping. I would never buy a anycubic I3 Mega again. I just had problems with it. And in the end I put more money into it than if I had bought a Prusa from the beginning. The anycubic was just a journey and adventure for me to learn about technology of 3d printing. But never a reliable machine until i had completely rebuild it.

Good video .. what is the addition on the bed travel on the back right? - seems a good fixture to have to lock the bed on that side.

Hello Sir. Me again.. Coming along with the build. Now stuck as I can find the rubber grommet for the rear body mount. Do you remember what bag you found it in or was it even of the plastic trees but I assume it's rubber? Thank you!

'Super help pls. Started by build tonight but can't get the Shock Cap Insert part 81512 on the shock cap... Been trying the last hour... Pls help.

Can't wait for more upcoming videos! Did you have to trim or modify the servo posts to make them fit? Thanks!

I'm going to have to look at my car, I didn't have to modify the chassis side guard for my exhaust.

I used your config as I'm also using TMC2209 but get this error: unable to read tmc uart. Any ideas? Thanks

What is your lathe machine models pls?
