FLSUN Printer Issue

[MHPrior80]

Yes. I have an FLSun prusa. Exactly what you mentioned.

In the video it appears that your 3D Printer is having a hard time finding the end-stop switch.

I also did not see the Z-Axis travel up or down to find the bed.

First you should test the Z-Axis the determine if it will raise and lower. Using the LCD controls.
Then you should test the Z-Axis Proximity Sensor raise the Z-Axis up in the middle then lower it using a metal spatula simulate the bed tap the Sensor.
This should cause the Z-Axis to stop moving down raise a little then continue down again this is part of the double tap to the simulated bed tap sensor again to stop.

If this work then your Z-Axis sensor is detecting the bed. If not then the Z-Axis Proximity Sensor in failing.

Alright thanks. I really appreciate the help on this. I think what I?m gonna do is go through all the wiring first and make sure everything is plugged in where it needs to be. Especially when parts are not moving tells me to double check all the wiring. Then I?ll go from there. I will keep you posted. Thanks again

Well after a couple days going back to the beginning here it is finally put together as should, wiring is set and auto level sensor set. Still having issues. I am including a link for the manual and a link for the recent video. I have no clue what to do now.

Have you tried to raise and lower the Z-Axis.

[MHPrior80]

Yes I have. It does move slowly but does raise and lower. Could it be an issue with the firmware?

[Roberts_Clif]

Using a terminal to control the 3D Printer Send "M119 - Endstop States "

Then manually press the end-stops to see if all work.
Then for the Proximity sensor you could use a spatula and tap the senso.r.

I still hear the stepper grinding, maybe the switch works and the end-stop rest plate is not pressing the switch blade...

[MHPrior80]

The problem I?m having is the bed is going forward but the switch is in the back of the printer. The bed should go backward not forward. Also too with the z limit switch it is not connected due to the auto leveling sensor. Not sure if that is an issue or not. I can?t figure out why the bed goes forwards when it?s suppose to go backwards.

Simply Change the Direction of the stepper.

// Invert the stepper direction. Change (or reverse the motor connector) if an axis goes the wrong way.
#define INVERT_X_DIR false
#define INVERT_Y_DIR false
#define INVERT_Z_DIR false
