Great. Thank you.

The support team over at AON have been really delaying getting back to me. However, my boss went ahead and ordered a duet EX3HC. The results were excellent right out of the gate. All of the layer shifted existed on the x-axis which at the time was powered by low current channels 🙄 . At any rate, I have new issues to uncover and fix but for now I will call this a victory. I will start a new thread in regards to complications I face with the expansion board.

Thanks for everyones help and suggestions, ultimately it led to discovering a trivial mistake.

the endstops do not stop my print from extruding. They only block further movement. Right now when my x axis goes into fault, the extruder keeps going while I want to abort the print. I thought just activate the reset pin on my expansion board. Why won't that work?

Thanks in advance

@antlestxp
"@dmbgo you want to be above 60 for the enclosure but not to high if printing small parts. Goal is to have the layer cool just enough to start to become solid but not enough that it shrinks."

To answer your last question first, yes, I did print 2 separate test cubes about 250mm apart, to see if the extra time for layers to "set" helped - it didn't, the issue remained unchanged.

I'm fairly sure now that it's not being caused by a shrinkage issue. I have, in the past, successfully printed objects in the same enclosure using ABS with similar settings.

in a day or so, I will try using PETG with its recommended settings to see if the issue is ABS, or happens with all mediums, as @fcwilt suggested.

Thank you, added G1 H2 X-1 Y-1 Z-1 and it is working fine now

Yes maybe backlash. @sungod3k can you provide a screen shot showing an isometric view?

@Dougal1957 said in More info regarding zesty tech nimble v1:

@fcwilt yes if the ripple is in an upward direction reduce steps or flow and vice versa

Thanks.

I assume by ripple you mean the faint "sloped" pattern that appears on some prints?

I will try your suggestions although that artifact has never troubled me. I only print functional parts where appearance is of little import.

@fcwilt
Thanks, I'll check that

@o_lampe pro-tip CTRL - F 🙂

No.

In the console send M303 H0 S60 to tune the bed.
Wait for it to finish.
Then send M303 H1 S200 to tune the hotend.
Wait for it to finish.
Then send M500 to save the results.
Then add M501 to the end of config.g.

That's it.

@jshelton Glad we could help.

@dc42 ok will give it try, thanks for the help.

@dc42 said in Duet3D 6HC + Toolboard missing filament on curves:

@jbarros, please try the latest unofficial 3.3beta main and expansion board firmware. It solves all the issues we are aware of except for a very slight reduction in actual vs. requested extrusion.

Per your previous comments, rounding issues?
Do you know the loss % and do you believe it's fixable?

It was well under 1%. I think one user reported it as 0.18%. I've already fixed it for the case that pressure advance is not in use.

would it be better to go back to FW 2.05? from the mecatronic switch to duet I have not yet printed anything, I'm curious to see how it works

it work thanks a alot

@OwenD genius! 😄

@evomotors said in Duet3 6CH + 3CH expansion board - Missing steps.:

@dc42 @T3P3Tony The issue is fixed in the last 3.3 build! Tested with DAA enabled and print looks great (didn't look into the diagnostic messages) . Thank you!

Do you want me to mark this as answered?

I'm pleased for you that your issues have been resolved. For myself, I've given up and "mothballed" my printer.

Maybe I'll pick it up again in 6 months or so but I've been battling firmware issues and coming up with "work arounds" since July 2019 and still have problems that need more work arounds. I've had enough...........

for the wiring the kapton heatmat was pre made, only extended the wires with 14AWG wires.
