@chrishamm can confirm this works.

sudo apt update
sudo apt full-upgrade
sudo rm /opt/dsf/conf/config.json
sudo systemctl reboot

@chrishamm new image with no updates works. M997 S2 F"unstable", M997 S2

@jay_s_uk Oops, I forgot to mention that. I edited my original post, but it's these in the 300C version:
https://www.sliceengineering.com/products/thermistor-high-temperature

I reorganized my macros into a couple folders have encountered some issues.

• In the web interface, I can no longer select all and download as zip. I really liked this feature because it was a quick way to make a local backup before I started messing around with code. I wish it worked with folders.

• On the Panel Due when I first boot up the machine I can see my folders represented with asterisks, which is great, but when I exit a folder, the macros persist on the initial screen. Closing and reopening the macro menu does not fix it, and navigating in and out of macros can cause illegible text artifacts to appear on the buttons.

I should note that I'm using a panel due 7i, with a duet 3 in SBC mode with a raspberry pi, running the 3.5 release candidate.

@dc42 Thanks! This version of the code works:

var fanSpeed = fans[1].requestedValue

while var.fanSpeed < 1 ; while less than full speed
	set var.fanSpeed = var.fanSpeed + 0.01 ; update variables
	if var.fanSpeed > 1 ; make sure variable never exceeds 1
		set var.fanSpeed = 1
	M106 P1 S{var.fanSpeed} ; set fan speed
	G4 S0.01 ; dc42 said to add this

echo "fan at full speed"

@jay_s_uk I tried commenting that out and still got this error:

Heater 1 fault: exceeded allowed temperature excursion: target 240.0°C actual 257.5°C

@jay_s_uk It shouldn't have changed, it was working great on 3.5.0 RC3. During the ordeal, I did attempt switching to stable and doing a downgrade according the documentation, which worked and DWC was connecting, but then when switched back to unstable, it started getting stuck at connecting... again. I want to also mention, that I have the printer beep at the end of the config.g file, and I hear it, so that means the code is at least running. It makes me think the issue is more on the web-interface side. I will try BOSSA and get back to you soon.

@dc42 @gloomyandy Thanks for your suggestions, that fixed the issue!

M106 P1 S0 H-1 C"Chamber Fan"             ; set fan 1 value, thermostatic control off

@deckingman OMG that's got to be it! I feel so stupid... I totally forgot that I changed from a 12V to 24V PSU... Thanks so much!

@dc42 How exactly do I modify the esteps/mm so that the plot crosses extrusion factor 1 at speed 0? I'm getting better results using a linear trendline, however, the issue I keep running into is this:

If I calibrate my esteps/mm at the slowest speed I use (1000mm/min for instance), then print some test prints at faster speeds, measure the widths, plot the results, my extrusion multiplier will always be off on the speed I calibrated at, i.e. if A = 0.0036, and I calibrated my multiplier to be 1 at 1000mm/min then my multiplier is now 1.0036 now at 1000mm/min.

@dc42 the steps/mm are correct. I have them set to the values specified by the extruder manufacturer.

Does this make more sense?

Book1.xlsx

• Print same part multiple times, only varying the print speed. (Two perimeter thick print, no infill)
• Measured the wall thickness several times, average them.
• Omit the 500mm/min speed because it is an outlier (may be a limitation of the pellet extruder)
• Theoretical bead width is 3.6mm, I take the nominal value (2*3.6mm) and divide it by the actual widths. This gives me an extrusion multiplier - I refer to it as the "corrective multiplier".
• Because I'm not using filament, my slicer has an arbitrary "filament diameter", I use the extrusion multiplier to recalculate a new filament diameter (Surface area * coefficient = surface area, solve for Diameter)
• I now create a new extrusion multiplier, based on the new extrusion multiplier at 1000mm/min being 1. This is calculated by taking the new nominal width, divided by the actual widths.
• I plot the extrusion multiplier vs the extrusion speed in mm/s (as specified in the M592 documentation) and apply a 2nd order polynomial trendline.

I end up with these coefficients:
M592 D2 A0.0047 B-0.00001 L1.29478

What is strange is that when I apply these, sometimes my extruder doesn't extrude at all.

Please let me know what you think. Thank you.

@dc42 I collected some data, but I'm not sure how to make an equation that fits the format. I can't set an intercept of 1. Was my mistake that I calibrated at my maximum speed?

I'm racking my brain trying to figure out how to make an equation that doesn't have a constant and I can't figure it out.

Marlin supports a constant:

@droftarts Can you explain or link me to an explanation of this equation: (1 + min(L, Av + Bv^2)) ?

I read through the forum posts linked in the M592 description but I still don't understand the theory behind that equation, let alone how to determine the A and B coefficents.

Thanks.

I've been testing a Dyze Pulsar and I've noticed that the print speed very much affects how much plastic exits the nozzle. I've done some testing by printing 3-inch cubes with the same profiles, but varying the print speed, weighed them. I came to the conclusion that as the speed increases, so should the extrusion multiplier. I've created fast/medium/slow printer profiles in Simplify3D V5 that work well. However, as I was trying to create a post-processor that would modify the extrusion distance based on the feed-rate, I wondered if this was a capability of the Duet?

@dc42 Interesting. Any idea on an estimated completion date on the feature request? Or maybe a workaround I could do instead? I want the user to be able to have a way out of a very long while loop.

Thanks.

@droftarts I updated to 3.5.3 and tested the code but no change, I then added a M400 like this below, and it still did not run the last few lines of code, line 11 & 12.

@jay_s_uk SBC mode, 3.5.3-rc.1. I'm afraid to update because that was an ordeal last time that bricked some of my expansion boards updating in sbc mode.

I have a bunch of code to automatically open/close a retractable cover on my printer and I have subsets of code that run different beeps to indicate motion and M291's to prompt the user. What I'm noticing is that it's not always running all of my code. I can't tell if line 10 isn't running b/c the motor is stopped with relay logic, lines 11 and 12 are definitely not running.
