I could use some help

fcwilt

@mac said in I could use some help:

the X-axis is messed up, and the y axis is okay, I guess. But that shaking thing is creep pee!

We can figure that out.

so I sent the command, and then I tried to move the print head. All it did was shake side to side,

What command are you referring to?

How did you try to move the print head?

Frederick

@fcwilt I started by entering the command that allows you to move the axis without homing first.

@fcwilt and then I used the incremental buttons to move the X axis towards the end stop in the left side of the printer. It’s possible that when I pushed the “move X 10mm left,” the print head went side to side 10 times?

@mac sounds more like a wire is loose on the X axis motor. Check your wiring.

@droftarts after reading through the code, I think you’re right. I did repair the red wire to X, so I’ll check that.

droftarts

@mac Fixed your Gcode posts. You selected the 'list' format (three dots vertically next to three lines) rather than the 'code' format (like </>). You can also edit your posts to fix them; click the three blue vertical dots on the right of a post, next to the upvote/downvote buttons, and select edit.

The symptoms you describe do suggest a stepper wiring issue.

... though usually if a phase was disconnected you would get an error. It's possible that the DWC jog buttons are just trying to move the axis too fast. Try sending something like G1 X10 F100 for a short, slow move. This should move the X axis 10mm at 100mm/min, so take 6 seconds.

The default for the jog buttons is 6000mm/min, or 100mm/sec. If you want to change this, it's in System > Machine specific > General tab, under 'Machine specific > Feedrate for move buttons'.

@droftarts Since my bed on the Y axis was behaving, I decided to change the X-motor's rotation to REVERSED also. When I tested it, that didn't go well the first time. I thought because I reversed the green and white endstop connector at the same time, that may have had something to do with the print head's back-and-forth behavior.

So I left the X-motor reversed, and changed the endstop wiring back. Now, GRN is white, and i05.in is green. Because of that, the x-motor's behaving. It appears that it's limited movement to the left (where the endstop is), has to do with where the board thinks the left of the bed is.

Can you tell me, once again, HOW to tell my board where the LEFT ENDSTOP for the X-AXIS is?

I'll assume that the process is the same for the Y and Z axis, and go from there?

Mac

@droftarts Because the X, Y, and Z motors are seem to be happy being reversed, my assumption is A) the wiring to the main connectors is backwards, and B) I need to change the EXTRUDER motor to REVERSED as well?

@droftarts So, I just switched to Console, and there's this message: 6/26/2022, 8:23.46 AM / Event / G28 X (new line) Driver 0.2 warning: phase A may be disconnected, phase B may be disconnected

Lovely. That means the Y-axis motor has failed, right?

Mac

@droftarts false alarm, the Y motor's working, but it's stopping way short of the front of the printer. So it's doing what the X motor is doing. There's a clue in that, I think.

@droftarts okay, final update for today. I homed Y. It went all the way to the right (as far as it thinks it can go, I gather), and started coming down. When I looked at it head-on, I saw that the BLTouch was off the board (to the right). So, I turned the machine off.
