Quoteflyway97 Do you want automatiac leveling? The The Servo motor is not used for leveling. No, I need extruders change with the servo.

Quoteto3dornottobe Search this link for 'servo' and you should be fine. The pinout of this clone-board is provided online (also in this thread) Just add the M280 Sxx command prior to your bed/z probing. Could you explaine how to connect, configure and control servo? I tryed but cant do this. Thanks.

Quotedintid Created a new instructables on how to add an extra fan or use fan with different voltage using PWM pin on the Sbase and configuring Smoothieware. Sbase/Smoothieware - Use a Free PWM Pin and Power Expander or SSR to Control Fans. Hi. Is it possible to use one of free PWM pins to control servo? If yes - please could you make the same instructions how to make it? Thanks.

QuoteVDX ... your screenshots shows, that it's not connected - can you connect? No, he can't. And he tries to solve this problem. But I think that his mainboard is damaged, unfortunately.

Quotetomi01_2000 i put it firmware.bin and config.txt from MKSSBase-firmware on the SD Card and boot on the printer at the end, on the SD was firmware.cur + config.txt The SD Card it is ok, i change it the usb cable ... I will try tomorrow, on different computers, one on windows 10, and one on linux mint Try to set uart0.baud_rate 250000 in your config file, and change it in the Pronterface. C

Quotetomi01_2000 I am trying to connect printer on computer using cable usb, and the computer it start to install the driver - automatically. On Pronterface - i try to connect, and i have "connecting...". And even if i wait 10 min nothing's happened. Do your printer has any reaction on commands which is sent from the display (axes moving, extruding etc)?

Guys, what about servo connection to the MKS SBase? It doesn't work properly. Maybe somebody could explain me what I did wrong? I have connected servo using external power supply. But when I send M280 command to the printer, the servo always turns on the one and same position. It not depend on S value (between 5 and 10). It is possible to connect servo or not in principle?

Re: New MKS SBASE Smoothieware-compatible board from China - 8 years ago

Quotebobc I had a look at servo specs before, to see if the control signal is 3.3V compatible. The answer is it depends on the servo. e.g. this one indicates 5V but this one says 3.3V to 5V The servo must still be powered at 5V (or whatever normal supply voltage) of course. So either find a servo with a known spec, or trial and error. Sparkfun sell a little level translator which should work

Quotearthurwolf Smoothie ( aha I nearly wrote "Smoothieboard" I mean any Smoothie-based board ) outputs 3.3V signals. Looking at the specs for your servo motor, I doubt that's enough to control it. Maybe the MKS SBASE thing has an actual "Servo" port that bumps things up to 5V ? Somebody here knows ? I have not find any special ports for servos, only several pins for self-design. It is strange t

Quotearthurwolf Pin 1.22 is not PWM-capable. Pin 1.23 is for example. See : Thanks. I have changed pin 1.22 to pin 1.23 and now have the next result. When I send M280 S5 or other value of S, the servo turns always on the same position. And only one time. If I send M280 command with another S value the servo is not turns. Only when I change the angle manually the M280 command works again and only

Re: New MKS SBASE Smoothieware-compatible board from China - 8 years ago

Quoteo_lampe Always use a separate 5V supply for the servo. Make sure, the ground is connected to GND on the Sbase and on the servo plug ( black ). Connect the external 5v line only to the ( red?) servo wire. The yellow or white servo wire is for the sbase signal. OK. I have connected the servo using external power supply. I have connected minus from the power supply both to servo and to ground p

Re: New MKS SBASE Smoothieware-compatible board from China - 8 years ago

Hi everybody. Has anyone connected the servo to the MKS SBase V1.2? Please, give the diagram how to connect the servo to the board physically. I can't find the +5 pin on the board. Only ground. How to connect the servo with external power supply for the servo to this board?
