@infiniteloop I hadn't thought of that, I will try a fresh nozzle and upgrade the fan, thanks for the suggestion

@Tech_Sam03 you may not need to reduce the P term by as much as that. Try 50 to 70% of the current value.

Dual IDEX sounds really interesting, I saw a brief glimpse of your printer on Instagram and it looks really good and congratulations on your award.

You might want to consider upgrading to a 6hc board - so that you can run different gcode on the two gantries in parallel.

Would be interested in finding out more about your design - such as the kinematics your are using, bed probing, head alignment etc.

@o_lampe tip forming pretty unreliable in my experience, even if it saves a bit of waste. Cutting pretty reliable and easy with a blade - i've done 10's of 1000s of colour changes on my Bambulab printers and so far have never needed to change the blade.

Long retractions also an issue with the MMU2/3. The Bambulab approach of rewinding spools much more reliable - although slow and complex, or the shorter multiple PTFE approach of AMS lite quicker for a limited number of colours.

Separate nozzle (if necessary hot end and extruder) much more preferable than any multiplexing approach both in terms of waste and speed.

@mickeey

the smart effector is original duet and the problem is there. the card was on another printer and never had problems

I think the fan0 connector failed because you wired the fan backwards. If you want to fix it, try replacing the MOSFET. See https://docs.duet3d.com/en/User_manual/Troubleshooting/Parts#fan-mosfet

I think you should also check the plug on the Smart Effector that connects to the Duet 2 board. These pins look like they are not fully inserted into the housing. There also looks like there might be some wires poking out, that may cause a short.

you had region on fan 2 everything works. thanks for all the support

Great, glad you got it working. Please check the above.

@RockB M106 P2 S1 should turn the LEDs on, and M106 P2 S0 should turn them off. Or disconnect them and test.

Isn't Trad Rack locked to Klipper? I did not see any reference to RRF in their Github page, nor any suggestion of being firmware agnostic.

OK, your answer would be obviouly "no" since you are doing it in fact. The question translates then to "how".
I can figure out by myself that the Fysetc StrideMax Dual works with RRF, but more details about the setup and control would be desirable for anyone like me is interested to implement something similar. The Smuff MMU solution is not supported any longer.

@Phaedrux thank you

@jltx you should add X0 Y0 to your two G1 R1 commands in resume.g. Also add Z0 to the second one.

@Phaedrux

While there is nothing wrong with doing that it is not needed, in my experience.

Here is the start code from Cura 5.10.0:

T0 M104 S0 M109 S0 M98 P"print_begin.g" M82 ;absolute extrusion mode M82 ;absolute extrusion mode M98 P"print_extrude_begin.g" M83 ;relative extrusion mode M83 ;relative extrusion mode G1 F1500 E-6.5 ;LAYER_COUNT:259 ;LAYER:0 M107

Note that the M104 and M109 are harmless as the call to user code follows them and there is no unwanted code that follows the call to the user code.

Here is the start code from Prusa 2.9.2:

M98 P"print_begin.g" G21 ; set units to millimeters G90 ; use absolute coordinates M83 ; use relative distances for extrusion M98 P"print_filament_begin.g" M107

Again there is no unwanted code that follows the calls to user code.

Not big deal, just thought I would mention it.

I'm using a modified version JadonMillers ultimate duet menu system. I changed the order of buttons to my preference. I am running 3.5.3 currently.

@mikeabuilder also look at M32.

@jltx

the wave function collapses and the cat is definitely dead.

Common wisdom: Never bet on a cat, they always know better…

@o_lampe said in Robotic kinematics:

@jay_s_uk Hmmm,
like Winter soldier?

My Bucky cosplay is at 1%.

@MintyTrebor perfect, now it starts. Thanks a lot!

@dc42 glad I asked. Would love to see the LaPlace transfer function because I am thinking about this wrong. I ended up with MZV @50 Hz with 0.05 because my X and Y have separate peaks and I can kill both.

@droftarts I can verify that the root cause is not reset button press, metallic debris, shorting of J32, condensation, or missing R30. Which leaves us ESD. We do have 24V brushed vacuum pumps on the system connected to out0 through out4. The odd thing is that the issue does not necessarily happen only when any one of the pumps is on. The issue has occurred with pumps being on or off.

So here is what we've tried in the past few weeks:

changed out both 3HC boards reporting the reset - no change in frequency from 1 per hour changed out all 3 3HC boards - issue reduced in frequency to 1 per day changed out 6HC board - issue greatly reduced in frequency to less than 1 per week

Now that the stoppages are so infrequent, the heat is off for the time being.

The next thing we are trying will be to get brushless vacuum pumps to replace the brushed units.

I'll table this issue for now and report back when the brushless pumps arrive.

@ash100 I guess you haven't run PID tuning since you were running firmware 3.4.x. I suggest you upgrade to either 3.5.4 or 3.6.0-rc.3 and then run PID tuning again. It has changed a lot since 3.4.x so read https://docs.duet3d.com/en/User_manual/Tuning/Duet_3_1HCL_tuning#manual-tuning for instructions.

@patrickwjoyce One for @chrishamm .

@sushrutshendey For a more comprehensive guide to set up AP mode, see https://docs.duet3d.com/en/User_manual/Machine_configuration/Networking#configuring-duet-in-wifi-access-point-mode

Giving us some detail, eg firmware version, commands that you have sent to the Duet, config.g, how you have set your PC, etc, etc, will help us to resolve this more quickly.

Have you been able to connect to the Duet via WiFi normally, and seen DWC? ie make sure you have the SD card set up correctly, and that there is a /www folder with the matching version of DWC in it. See https://docs.duet3d.com/en/User_manual/RepRapFirmware/SD_card#sd-card-structure
