I could use some help
-
@fcwilt I'm using G1 H2 Y-20 F2600 to send the bed back to the Y-endstop. The transmission rate is working very well. The foot of the bed (underneath it, on the mounting hardware for the bed), is depressing the endstop. Status is reporting -220.0.
The Home Y jog buttons are active. However, a single click on Y+50 sends the bed all the way to Y= 0.0, which is at the front of the bed.

@fcwilt more bad news: I went to the Dashboard. There, Display is showing me the position of the bed. (So maybe, when you're in the CONSOLE, that information isn't available?).
Anyways, the bed is at 87 right now. That's the 18" mark (the 457mm mark).
The jog selections for Home Y are available.

Hey Mac,
As to what the DWC reports: It means nothing until the axis is homed. Yes the display changes as you issue Y movement commands but the DWC has no reference as to where the bed was before the move.
Do you have a part number for the X, Y and Z steppers? It may be printed somewhere on the stepper itself.
In your config.g file: The M906 commands which set the currents for the steppers: Where did you get those values?
Thanks.

@fcwilt I think what we've learned from this experiment is: G1 H1 Y-20 F2600 doesn't communicate with the board / printer very well, and G1 H2 Y-20 F2600 seems to have no problem communicating with the board / printer?

Hi Mac,
The particular command issued would not in anyway affect communication with the board.
The configuration of the board may be preventing the commands from being performed correctly.
Did you do the test I asked for? The one using a series of G1 H1 Y-10 commands to move the bed until it reach the endstop.
Do you remember that list of steps I posted?
Thanks.

That's a link to what I think are the motors used in the Xvico.
If you scroll to the bottom of the page, there's a run-down of the motor's specs.

Thanks, Mac.
That is just what I needed to know.
Did they come with the printer or are the new items you installed?

@fcwilt the motors that came with the printer are painted black. there is no information on them. I'm trying to think if I still have the literature? (I'll work on that). The pictures I just posted (twice), are based on googling Xvico motors, Alienexpress. That's what I found, those pictures match my motors to a T, although the wiring that came with mine is colored differently.

Well steppers with very different characteristics can all look the same as it is the wiring on the sides that makes the difference.
So backing up to the question about the M906 current settings for the existing steppers - where did those value come from?
Thanks.

@fcwilt you must be gone.
I'm going to go look for the box the Xvico came in.

I was outside filling up the hot tub.
The specs you posted are reasonable as those steppers are but 38mm in length.
And if they are the steppers that came with the printer then my theory as to what is wrong is looking very good.
Still when you get a chance run the test I posted about using G1 H1 Y-10 moves repeatedly until the endstop is activated.
Until I know the result of that I cannot describe the next test to try.
Thanks.

@fcwilt I did the test, multiple times this morning, and posted the results, which are above this post. I'm going to copy and paste them, and resend them to you.

@fcwilt see above?

@fcwilt said in I could use some help:
here are the results: I discovered that my wireless mouse and the printer aren't really communicating. Sometimes, the bed moves the whole 10mm's, sometimes it turns half or less of that. So it isn't click, pulley turns, bed moves 10mm's, it's more like click, nothing happens, click, the pulley turns 3 mm's, click, the pulley doesn't do anything, click, it turns 10mm's.
So I turned off the wireless mouse, and plugged a USB mouse into my keyboard.
I'm going to do the test again, from the beginning. -
@fcwilt said in I could use some help:
Test no. 2, same results with a wired mouse. I'm clicking the same way every time, and that's not working every time. Maybe the wifi is wonky?
Status isn't reporting anything. -
@fcwilt said in I could use some help:
so here's some bad news: I'm experimenting with the code (G1 H1 Y-XX FXXXX). I used 2600 for the F, because that "speed?" worked last night? No change, really. The signal's going to the printer are having a hard time getting there, or, the printer's having a hard time understanding and acting on them?
So then I changed the code to: G1 H2 Y-20 F2600
The bed slides towards the rear like it's on ice.
And here's some more bad news: Status is displaying the position of the bed. Y is at -160 now.
The end-stop fully compressed.
