Sobreiro

Yes i have it enabled, but still the same... About the 240ohm resistor, is to install between servo and gorund? There's any problem with the 4,7k between servo and +5V?

I realized i have a fake bltouch. Maybe thats why it doens't connect properly? About having a V08, what's the right servos configuration in the firmware? EDIT: I saw this: Use the Resistor. Older BLTouch Classic probes and most clones required the use of an included 240 Ohm resistor to function with 3.3v logic boards. Again, this shouldn't be necessary with the Duet, but there have been reports that it has solved problems, especially with clones.

I have a 4,7k resistor between yellow (servo) and red (+5V) wires. It's that resistor you talking about?

Yes i recompile and install my own firmware and other from other forum, but i got the same result. I can force (pull down) the bl touch to extend and turn off the red light. Even in that way it doesn't stop at z min. EDIT: I've tried to send some commands for the printer. M280 P0 S10, M280 P0 S90 and M280 P0 S120 does nothing! The bl-touch don't respond for this commands and when using M119, z_min is always open.

I have an Alfawise U30 with a V08 motherboard. Finally, the step down to turn on the bl-touch has arrived. I made the following connections: - Red (+ 5V Step Down); - Green (Ground Step Down); Yellow (Servo); Black and White (Z min); After do my own configuration and try other configuration i download, i got always this problems: - After turn on my printer, got red light on bl-touch. It's retracted. After performance a home x, y, z, it doesn´t stop! Even if I force pull down the bl touch (and the red light turns off). Need help to understand what’s the problem.

Let me check the connections: Red = Step Down Module +5V; Greeen = Step Down Module 0V; Yellow (Servo) = Pin2 J26; Black = Pin1 J25; White = Pin2 J25; That's it?

Hi! I am trying to install a BlTouch on my Alfawise U30. However, I verify that the motherboard version is V8, that is, it does not have the connection for the + 5V (red), ground (green) and servo (yellow) connectors. When looking for how to connect the BlTouch in this version of the motherboard, I verify that I must remove a resistance and solder the + 5V to a component of the board. I was wondering if I can use a 5V power supply to connect the red and green wire instead of soldering the 5V. Removing the resistance is no problem.

Hi! I installed Marlin 2.0 on my U30 and noticed that a situation occurs. I use Cura to make the files in gcode. It turns out that when printing the printer sometimes prints out of the print area, going in front of an X or Y edge (goes to X = 0/230 or Y = 0/230) and returns to the coordinates where you are printing. This printing leaves a trace of material that is not desirable or I understand why! When I go to gcode I don't see this mirrored in the code, because there should be code with movement only in X or Y ... Another situation that occurs is that the printing speed is sometimes so low that it seems that it has stopped printing. Anyone who has this happened?
