Hi, I have a duetWifi with firmware 1.21, I just broke my SD card and I'm trying to re-install. Upon succeeding I just want to comment that it's complicated for no reason. Could you please provide a disk-image version for each release version of the firmware.

Etcher is a free multi-platform tool that can be use for the task...

@tekkydave
Thanks Yes I've many backup of my config file, just arguing that a 3 steps process Download image, burn image, replace config files is simpler that a 10 steps one...

@danal said in Sd card disk Image:

Actually, I agree that a complete image for each MAJOR release would be a wonderful thing for the community. I'm never 101% confident that I have the right things on an SD, because tidbits of information, like which iap... or the exact name of the firmware file, or similar are spread all over the place. The forum, the wiki, release notes, maybe other places.

Thanks you totally get my point...

With one caveat: Any necessary release-to-release config incompatibilities.

Yes that's life, if you upgrade from a much lower version you must be willing to put the effort.

@t3p3tony who's to say that the extruder would not be sided close to the camera

@stephen6309 Thank. but I would have prefer something build in the Duet like a external script auto triggered. Because if I use many slicer or config this setting becomes annoying to include in each config

@zapta said in 100C resettable Thermal Cut-Off for 24V heated beat:

BTW, what resettable thermal cut-off do you have in mind?

For now I mounted one exactly like those in a Kettle 100C ;-), after activation the thermo expandable medium while contract and close the circuit again...

Hi, can someone tell me if there is an easy way to have some kind of Gcode script event that could trigger a motor movement of the Duet base upon the position of the virtual Z position on a delta printer using a DuetWifi controler.

I have a camera on the Z axis rig to an linear stage, I would like the camera to follow the Z printing position but not necessarily on 1 to 1 ratio

Hi I'm instaling a 100C auto-resettable Thermal cut-off my 24V head bed for my printer should I worry about the effect of transients on the output of the mosfet controling the PWM on my Duet?

Maybe a should use a non re-settable one...

Something like the RailCoreII which has shown incredibly detailed prints at very low layer heights. It's a lot more sturdy and solid than a Dbot.

Mine is a custom build and a tank, but I wonder if I should remove the sprint bed like I did with my delta. I'm somewhat encouraged by the results

Thanks for your suggestions

I think a lot of the surface finish at this fine extrusion level is dictated by vibration. Bearings, rolling wheels, belts, motors, resonant vibrations. The filament being layed down is so thin that it seems to cool very quickly and all the little pressure vibrations in the filament get locked in place before they have a chance to relax and dissipate.

Yes I think you're right, be we must take in consideration that a glossy black is the worst case scenario, but I like this filament it's ESUN PLA+ very sturdy can make a .25mm circular plastic band and it will not break under stress unlike native PLA and it's relatively cheap 30$US per Kg often is special at 20$

Furthermore, the extrusion speed is very slow. The gear on my titan aero barely moves when I'm printing at 0.05mm layer height. I think at that low speed some extrusion steps are getting missed.

I've bought a twin gear metal extruder to help reduce this
https://dyzedesign.com/dyzextruder-gt-extruder/
but must pay the price in weight event it's only 250gram ( no much higher than your Titan) . Bowden setups reduce all this but hysteresis on the retraction is a pain for small details

This has been discussed before in another thread. Increasing the microstepping value for the extruder can help, but you can then run into hiccups and missed steps that way. @wilriker even made a calculator. https://wilriker.github.io/microstep-calculator/

I really like the look and feel of 0.05mm layer heights. It feels almost like an injection molded part, but there are so many new artifacts that get exposed when the layer lines go away. I've given up on such low layer heights entirely until I have a printer more capable of the resolution.

0.15 layer height with a 0.6mm nozzle is my new favorite. You can print

Nice Turtle! I do mostly mechanical part and .6mm don't give the clearance I want.

@dc42
Thanks, I think I've nail down the problem but with my delta and fusion 360 I always generate the STL files using the high setting and never had such problem. Now with my new coreXY direct extrusion I think the printer is more precise and I see defect I didn't saw before. With very less visible layer lines at 0.05mm height and a .25mm nozzle surface is more mirror like and any light defects are visible. I think I even see the belt pattern. Light orientation play a big role has you can see in the following pictures. Jerk and acceleration are still a little to high the carriage is heavy 400 gram. To the touch the piece surface is like silk don't know how much I can go. Maybe I will change the idler wheels for some toothed version to reduce belt vibration

@3doeste said in Surface Finish : Duet path planner?:

Hi, interpolation only works with 16 microsteps, you are using 128.

it's disable on the second line
M350 X128 Y128 Z128 E128 I0

@phaedrux said in Surface Finish : Duet path planner?:

Are you using pressure advance?

Yes and helped a lot, no more blob problem... I will try to deactivate it

"Have you tried a different spool of filament? Or different slicer?" yes and no not with this object, but the problem is always there
