Error: bad Command XXX W/RRF 3.2 and leveling issue

[3DPrintingWorld]

After installing RRF 3.2, I get "Error: Bad Command" with a three digit error number, when the reset button is hit. The error number changes to a new number every time the reset button is hit.

Every other time power is cycled, T1 hotend fan turns on and stays on regardless of the hotend temperature. If I hit the reset button again, the next time it will shutoff. Hit it again and it will start.

Lastly, around the same time my three motor independently leveled Z axis stopped leveling properly. Not sure if its related, I've been trying to diagnose it since 3.2 came out. I've had everything apart two times and I cant find anything wrong mechanically. The code had not changed and I've double checked it a bunch of times. Two other people are using the same or similar config for the same printer. My printer leveled great for about six months prior.

The BL touch tests a deviation around .005, with moving the carriage between every probe. It still levels about .5mm out of level, back left always low, front right high. If I run trigger height test over the three points I used to level, it gives me a deviation of .005, even thought the points are almost .5mm off in reality.

I'm not sure if the leveling is related but it started around the same time. Any help would be appreciated as I cant see to find the issue.

run M98 P"config.g" and post output.

post m122 output

and post your bed.g and config.g

I assume you're seeing this on a PanelDue? This is known and nothing to worry about. What firmware version on the PanelDue?

Please post the information veti asked for for further help.

I am one of the other 2 that are running the same printer design
What was the version you ran before update to 3.2.
I updated while changing Z steppers and have the same thing with the back left low and front right high but within 0.15 , so I thought it is something with the magnet base and spring steel sheet. Later I will roll back to 3.0 and try.
One more thing for now I am runing G29 with 6*6 grid every print and there is some variaton map to map.

@martin7404 Hey Martin, I didn't realize you were having a issue as well. I was on 3.1.1, Gui is still on it and is not having the same issue. We double checked our config's but could not find any differences that would matter. I just tried reverting back to 3.1.1, I still get the error but not the fan issue, and its still not homing properly. Maybe updating the firmware is just a coincidence as I was making some other changes at the same time.

Strange that your map is not repeating. I've done trigger testes where I move the probe 200mm in each direction and back before probes and it repeats within .001-.01. I don't understand how I can use three points to level, then do a trigger height on each point and it says the deviation is only .005, but its actually closer to .25mm.

I just reverted to 3.1.1 to see what happens and the fan no longer turns on at startup but I still get the alarms. The bed is still not leveling properly so I assume that is unrelated.

This is bed.g, I do three points as close as I can to the beds connection points. I have also tried four corners and three points closer to center but results are similar.

@3DPrintingWorld Before your post I thought 0.15 was from the magnetic mat and steel sheet. Before the update, I was with 3.0. The 3 Z motors are new , but my Z print calibration is within 0.02mm so the steps are correct For G32 I do it 2 times from the beginning

M92 X100.00 U100.00 Y100.00:100.00 Z1096:1096:1096 E415.00:655.00

z does not allow for more than one value

remove them from M566 M92 M203 M201 and M906

what i did for the bed leveling to see if the adjustments were correct is look at the heightmap before and after a g32.

[martin7404]

Anyway, the manual says it will take the first one, so no problem. Also as stated it was working fine before the firmware update.
What G32 has to do with the heightmap, that is made with g29 probing. G32 just levels the bed on 3 points

I have no idea if this is related but it might be.

On my 3 Z stepper printer each Z stepper has it's own end stop sensor. The Z steppers are on the Duex 5 board.

I home Z using the end stop sensors which have been carefully adjusted to result in the bed being very nearly level.

I then use G32 to perform the final bed leveling.

Under 3.1.1 everything worked fine for months and months of use. I recently upgraded to 3.2.0.

Under 3.2.0 Z homing frequently failed as one of the Z steppers would fail to stop when it's end stop sensor was triggered.

Since I could not rely on the Z homing I never moved on to the next step of using G32 so I cannot say if that would have worked or not.

I'll take them out to neaten it up anyways.

Agreed, the height map should not have anything to do with it. Right now the height map is cleared and I'm just trying to get the bed level to the nozzle.

post a picture of the mesh bed leveling

So I roll back to 3.1.1 and the heatmap is consistent, the tramming is working kind of. the deviation can be due to magnetic mat + steel sheet

So I roll back to 3.1.1

Surprised that made a difference, it didn't do anything for me when I reverted.

The leveling seems very consistent, just not level. I'm gong to try putting incorrect locations into the M671 to see if I can trick it into leveling properly. The front right corner is high so I'm going to move that point out further in the X until the bed is level. If I adjust just this motor by hand it seems to fall into level so it should work.

[3DPrintingWorld]

The two front motors are aligned in the X axis so I physically swapped motors, and switched the rotation direction in the config so they run in the correct direction. Now when it corrects for level it should be backwards, but it levels it exactly the same! Left back corner low, right front corner high.

I also moved the front right motor location in the M671 over as much as 350mm, but it has no effect and levels exactly the same! Left back corner low, right front corner high.

How can making these changes have no effect on level? The results should be all jacked up but nothing I do seems to have any effect on the outcome. At the same time, I don't understand how its correcting to the same bad plan every time even though I've giving it bad information.
