I could use some help

@deckingman thanks, contrary to what people believe, I do read the documentation. As for fishing, never caught a fish in my life, but my middle son was a commercial fisherman for 10 years? Fish is way too expensive for my budget.

@mac said in I could use some help:
NOTE: I keep looking at the Z motor / Steps per mm; it's set at 4000? The Max. Speed Change (mm/s) is set at 1, the Max. Speed (mm/s) is set at 10, and the Acceleration (mm/s-squared) is set at 200? Is that right?
Don't worry about most of those settings right now.
The only one of initial importance is the steps / mm.
It's easy enough to determine by testing what the value should be. Like before, you command a move of a known length, say, 50mm and measure with a ruler/scale how far it actually moved. From that you can determine the actual value or very close to it.

@fcwilt I'll put that on the list of checks I'm making.
After I changed the information on the motors (from 600 mA to 1200 mA), and loaded a new config.g to DWC, surprise surprise, the "!^'s" are back on the endstops (05, 06, and 02).
I deleted them, and saved the config.g, and rebooted the machine.
All the motors are 1200 mA now, and the endstops are P"io5.in", P"io6.in" and P"io2.in".
That DO - something command that Ian suggested is gone. I'm going to put it back in (after I find in it in the thread).

@mac Okay, TEST No. 1: M119 SEND.
Result: Endstops - X: not stopped, Y: not stopped, A: not stopped, Z probe: not stopped.
TEST No. 2: M119 SEND with each endstop depressed (one at a time).
Result: Endstops - X: at max stop, Y: not stopped, Z: not stopped, Z probe: not stopped.
Result: Endstop - X: not stopped, Y: at max stop, Z; not stopped, Z probe: not stopped.
Result: Endstops - X: not stopped, Y: not stopped, Z; at min stop, Z probe: not stopped.TEST No. 3: Execute M564 H0 S0 to jog each axis, are they going in the correct direction?
M564 H0 S0 executed.
Change to Dashboard.
All jog buttons are available.TEST X: I tried to jog right and left 10mm. Nothing happened.
TEST Y: I tried to jog Y-10. The bed shuddered in place.
TEST Z: I tried to jog Z-5 and Z+5. Z did not move.NOTE: I had to extend the X and Z endstops because I printed out a box for the board, and mounted it on the right Z rail. I don't know if this is possible, or not, but the wire I used to extend the endstops was slightly larger than the original wire.
There is also the possibility that the extensions are shorting out. I'll have to check that.
I'll also check the board to see if I made an error plugging the endstops in.
Given that the M119 tests worked, it seems like the endstops should be working?
RESULTS: X, Y, and Z failed to perform as expected.
TEST No. 4
G91 (sets relative movement, G1 H1 Y-10 F3600 what happens?
G1 H1 Y-10 F3600 SENT
RESULT: Bed shuddered in place.
At this point, I'm going to suspend the test.

I had nothing (I know of) to do with that change. I did research this thread, found Ian's and FcWilt's messages, and changed them to the above, however.

@mac well, I was really hoping that X2, Y2 Z1 code was the problem. I was hoping even more that X1, Y1, Z1 would allow me to jog the bed back 10 mm. No Such Luck. It shuddered in place for a brief moment, and that was that.
-
@mac I've been working on this machine since 2 AM. Putting the new motors in, putting the board in a box, and wiring everything together, putting the bed back together after I reinforced the mounting plate.
All for nothing.

@deckingman @droftarts @fcwilt
Here’s something completely different:
That antenna’s from one of my spare quadcopters that isn’t legal to fly anymore. I put it on the Duet Mini 5+ to see if it would work, and / or improve reception. In my opinion it improved reception a lot!
Mac
-
@mac sorry this change hasn’t gone to plan. Did you check the phases on the new motors? Can you take a picture of one of the new motors, of the wiring coming out, and the wiring of the Duet?
Your config looks sensible. You rewired the endstops to NC?
Ian

@droftarts Hey, Ian, good to hear from you. I'll take some pictures and answer your questions in the next post.
Mac

@droftarts okay, here’s what I know at the moment. Since the y-axis was shuddering, I decided to test it. Here’s a picture of my first test.
The wiring is black, green, blue, red. From the top of the board, which is where the wifi is, down. So that should be A+ (Black), A- (Green), B+ (Blue), B- (Red).
When I short black and green, the bed is very hard to move.
Here’s the thing that makes no sense! When I short blue and red, the bed is EASY to push back and forth.
According to the information that came with these motors, blue and red are B+ and B-!
I did not check the phases initially because I thought I had concrete written /printed info from the company I bought these motors from.
Here’s a picture of the wiring. REM: the board is upside down.

Hi Mark,
A few things I want to ask:
1st question:
When you made that video, when facing the printer, the X endstop was at the left end of the X axis and the Y endstop was at the back of the printer.
Has that changed?
If it has not changed those endstops are at the min end of X and Y but the M119 is reporting the max end for X and Y.
2nd question:
Do the steppers have a connector as opposed to the wires being a permanent part of the stepper?
3rd question:
If the steppers do have a connector did you check the continuity of the cable with the duet connectors attached?

@mac do you ever get any “phase disconnected” errors in DWC? Because it really sounds like the blue or red wire are not making the connection. That would explain the axis just shuddering, and no resistance when you short it.
Ian
-
@droftarts @fcwilt the problem’s in the connectors I made. Out of three connectors tested, X, Y, and Z, Y shuddered, X and Z did nothing. That’s ten connectors out of twelve that are shite.
I’ve been working for 13 hours. Time to take a break.
Mac

@fcwilt the motors are fine, the cables that came with them are fine. I checked. It’s the connectors I installed. 10 out of 12 are shite.

Hi Mac
Whenever you return to work perhaps you could find a way to make a video showing us how you are crimping those contacts onto the wire.
I've done hundreds of such crimps and I might mess up 1 out of 100.
Perhaps we can spot the problem you are having.

@fcwilt No, yes, no (sad face).
But we're over it, and we're at it again. I haven't eating in eight hours, so I'm going to have a cheese sandwich and then I'm turning in.
Maybe tomorrow we'll share some pictures of the Rat's Next that Frankenstein's Cinderella lives in.

@fcwilt If I had a camera I could hold in my mouth, I might do that.
I'll think about it.
