All working as expected now thankyou.

I think the key change was setting the correct Z height

@nick9one1

figured it out - some weirdness with FTP. When I copy the www files to the SD manually it works.

@Phaedrux said in problems with pressure advance calibration:

retract on layer change

Thank you. Yes I have retract on layer change enabled

I've changed the z values you suggested and set the slicer to start the pressure advance at 0.035 in increments to 0.055. Printing now

I'm struggling to reconcile some of the instructions for wiring the ADAFRUIT LIS3DH to the Duet wifi 2 (some of the pin names on the accelerometer wiki dont exactly match what is silkscreened on the LIS3DH)
https://duet3d.dozuki.com/Wiki/Accelerometers

specifically;
(from the wiki)

MOSI (also called SDI) - There is no pin labelled this, maybe SDA?
SCLK - There is no pin labelled this, is SCL the same?

@phaedrux

I think I've found the problem. The second tool I added to config.g had D1 instead of D0.
The printer only has one hotend and extruder so they are 'virtual' tools that let me change filament print settings (temp, retraction etc.) in the slicer.

@phaedrux

update - after making a few changes the hotend is now heating without the error.

The all metal throat is secured by two grub screws to the body/heatsink. Although properly secured, I think the throat was heating up, expanding slightly and making better contact with the heatsink, causing it to dump heat a bit quicker and triggering the error.
I've added some thermal compound to the throat/heatsink, re-tuned and can now heat from cold without any issues.

@dc42
thanks. I've tried a coupe of different cards with the same result.

The card I'm using is 100MB/s UHS class 1.

I've dropped the sample rate down to 100, and only for the X axis so the gcode looks like this;

G1 X-50 G4 S2 M956 X P0 S100 A0 G4 P10 G1 X50 F20000

the csv contains;
could it still be a wiring issue?

this is how its currently wired

it was alignment of the Y rails causing the problem. Unless they are perfectly aligned they can bind.

figured out the last bit. I didnt need to define a pin in M574 Z

M574 Z1 S2 

not

M574 Z1 S1 P"121.io0.in"

it's always something simple.

Pressure advance should be 0.07 not 0.7!

Thank you !!

I have a Toolboard with the integrated accelerometer and its correctly configured.

The documentation does a good job of explaining how to setup the accelerometer, but there seems to be nothing about how to interpret the data?

At the bottom of this page there is a section called "Configure the Input Shaper" but it doesn't give any information on how to do it?
https://duet3d.dozuki.com/Wiki/Accelerometers

can anyone help?

@phaedrux

I only have one tool, but have two defined in the config so I can more easily do a filament type change in superslicer.

kind of like this;

going back to M563 - I must have swapped the fan wiring over when installing the new toolboard;

I've swapped F0 to be F1 and it seems to work

but what is slightly confusing is the two fans seem to be linked in the GUI.

If the print requires 100% fan speed both sliders move, then drop down to 40%

@jay_s_uk said in Part fan not starting after toolboard upgrade:

Should this be F1?

I've just swapped to a V1.1 toolboard and for some reason my part cooling fan doesnt start.

The control slider on the web interface works, and I can control the fan with it during a print. I presume its something in the GCODE?

I have a LC1 1.1 with the latest beta firmware.

; Accel
M955 P121.0 I10

I think I have the correct orientation here;

I've followed the instructions and have collected some sample data with

; Duet 3 Toolboard 1LC at CAN address 121 (M956 P121.0)
G1 X-50 G4 S2 G1 X50 F20000 M400 M956 P121.0 S1000 A0

The sampled data looks like this;

I think I have the correct orientation here;

does that look correct?
How do I go about using this to configure the shaper?

Does anyone else finds the new JST terminals on the toolboard 1.1 fiddly and difficult?

The screw terminals were so much better on the 1.0! I cant understand why there is a change. Cost maybe?

Any tips on crimping them?

@phaedrux

Single filament prints work fine too.
