MP3DP V4 Build

Doing some searching, I am seeing.

M111 S247, another debug, more detailed.

M48 is a probe repeatability test.

Jonathjon · March 20, 2023, 9:16pm

It probed 24 of 25 points. the last point (same as always) is where it comes down but stops just before it touches. It doesnt crash the bed if its leveling from print gcode. but when i send just the g29 in octoprint terminal when it hits that last point and fails it crashes and disconnects octoprint. also has kill called on the screen.

Jonathjon · March 20, 2023, 9:17pm

I will try this one…if its unsuccessful i will try the M48

This is from the M111 S247

Turns out i was an idiot and had “Surpress position messages” checked so thats why i didnt get any info on the others.

vicious1 · March 20, 2023, 9:40pm

Hang on let me try to find a visualizer. It seems like your Z values are varying a lot. Are you sure the bltouch is tight, and the Carriage is tightened to the rail?

Make sure the carriage is tight to the bearings, and make sure the X rail is tight to the left and right pieces.

Jonathjon · March 20, 2023, 9:47pm

The damn fan mount was loose. I tell you what this thing makes me look like an idiot every day LOL. i Caught hell getting that on there with the rubber sock on the hot end and could have sworn it was all good and tight

vicious1 · March 20, 2023, 9:47pm

I can visualize that. Try

G29 S0

To me it looks like each direction is vastly different Z values. I had that happen when my V3 would wear out and the wires would pull and push on a loose carriage.

vicious1 · March 20, 2023, 9:49pm

Who know you were a two pistol toting cowboy…Two smoking guns so far…is there one hidden in your boot???

Jonathjon · March 20, 2023, 9:52pm

Not so sure about that. I had just started G29 when you posted…it failed earlier than usual this time…

Jonathjon · March 20, 2023, 9:54pm

Going to try this one now…

Jonathjon · March 20, 2023, 10:00pm

It did NOT like G29 S0. No response at all on the terminal just disconnected from Octoprint and crashed the bed…

vicious1 · March 20, 2023, 10:18pm

I just had a printer finish. G29 S0 crashed mine as well. Let me find the mesh output.

vicious1 · March 20, 2023, 10:21pm

M420 T1 V1

Jonathjon · March 20, 2023, 10:26pm

M420 T1 V1
echo:Invalid mesh.
echo:Bed Leveling OFF
echo:Fade Height 5.00
ok

vicious1 · March 20, 2023, 10:33pm

Hmm so g29 has never succeeded in creating a mesh. If you make a change through the LCD will the save to eeprom feature work? Maybe your eeprom is off.

Jonathjon · March 20, 2023, 10:35pm

It says it saves. It has never completed a mesh Always fails either at the very end or at the end of the middle row.

vicious1 · March 20, 2023, 10:36pm

Maybe double check config advance. There is a probe offset area, maybe you did the math wrong and it is trying to probe outside your usable area. I have my offset by 10mm all the way around I think.

Jonathjon · March 20, 2023, 10:38pm

99% sure that’s what i did as well. I have looked and it stays on the PEI sheet everywhere. I’m going to try to do it again and take a video and post. See if you see anything I’m not.

vicious1 · March 20, 2023, 10:39pm

Search mesh inset.

It has to be larger than the offset of the probe.

So my defaults should work as long as the bed is set right.
