Hi, You didn't mention what sort of filament you are using. On my Nimble/E3Dv6 setup I use 1mm retraction for PLA and to date it has been working fine. What material/temp are you using? Frederick

But how can I calculate those values? The values of M208 for SCARA are in mm or degrees?

@nikker Ahhhh sounds like the default rules were set to DENY, possibly during your first run through you set the default FORWARD rule to accept, You possibly ran something like iptables -P FORWARD ACCEPT or the ACCEPT rule you provided above. Anyway really good news hearing its all setup and running reliably.

@agniusm said in Consistent ripples on prints: On genuine duet board there are C shaped artifacts that you might not see in photos clearly, 2 at the very right side are more visible (red sample) on x axis photo (still it might be caused by minuscule upobservable differences in machines) . Somehow i lean towards motor incompatibility to duet. Blind guess but those motors are not made equal. Yeah, were I in your position I might order a similar stepper that is "supposed" to be a bit better quality and try it. It won't break the bank.

@dc42 So it started working on all browsers, and connects instantly again. The only thing I did was re-write a new config.g file to the SD card with minor machine modifications (namely motor direction) Another difference was that I changed the machine name in the new Config.g file. If it happens again, I will try changing only the machine name to see if it has an affect.

@dc42 I will upload a video this weekend of the material change in process, so that everyone can see where the issue lies and better understand how the mechanical side of my filament selector works. On another note, Thank you for always being so attentive to this forum! I don’t think I’ve ever posed a question that you didn’t have some input on. I really appreciate that!

@underdonesushi I have a cartesian printer, here you can read some info: https://forum.duet3d.com/topic/7148/qidi-x-pro-ffcp-clone-conversion-to-duet-2-wifi

@jrdm said in Thermostatic fan control based on driver die temp?: OK I think I misunderstood what Deckingman was doing here. It turns out there isn't a full scale temperature sensor available in the 2660 die. He must have set up his own separate thermistors then. I believe that is exactly what @deckingman has done. The MCU should provide a very close proxy temp for the drivers. Just make sure you've calibrated the temp offset for the MCU temp sensor. That way if your board fan is cooling based on the MCU it should keep the drivers well within range. https://duet3d.dozuki.com/Wiki/Calibrating_the_CPU_temperature The example fan setup provided by Resam above works quite well.

As an aside, I'm curious what your overall impression of using the Palette 2 with the Duet has been since it's geared towards being used with Octoprint.

One thing counterintuitive to a lot of people is if you have one fan connected wrong or maybe bad it can kill them all. I presume it drags the supply down? It's happened to me. I got lucky and no damage occurred.

Injecting a comment about Ender 3 revisions... I just saw the other day they have started shipping with silicone boots on the hot end instead of tape.

@agniusm said in Configuring 12864 LCD on Maestro?: Sorry, what? Kidding dude

@Catalin_RO it works super well -- just a couple of logic circuits -- 3.3v friendly chips and it works perfectly. I ended up designing a PCB and getting it made in China for $30 -- so it's nice and professional -- it takes a few 10 pin ribbons from duet, and has outputs for the 2 physical end stops (Y and U axis) + power and I plug in the extra steppers + end stops into it. There is no latency since it's just basic logic gates. One benefit I can't ever crash the X gantries past the end stops since the step pin stops being sent when end stop is hit and direction is into the end stop, so even safer than software limits

@neonode What size of ball screws are you using (length, diameter and pitch) and what size of stepper (NEMA* and the torque)?

If you change something, it also shows the z-hop height as first layer height. Edit - not S3D, Slic3r PE (2.02 RC5)

Officially I'm not saying it is good or bad. The screen is nice. But the firmware development is way behind... Way behind....

Unknown as the webapp was down and I don't have the LCD connected so I wasn't able to examine the state of the controller. I manually lifted the effector and power cycled the controller. The PETG was molten so it was still at or around operational temperature. I'll post the firmware version when I get home. Do you know if there are any debug options that can be enabled and if there are any crash logs available? Ok, RTFM Some combination of M929/M111/M114/M122 might do the trick.

@dc42 got it -- PS -- love how super simple it was to add T4 and T5 for different combination of duplicate printing -- really slick, I thought I would need to have different config modes for regular iQUEX vs duplication, but this is super neat, I just have T4 defined as duplication of extruders on gantry 1 and T5 as duplication of extruders on gantry 1 and one of the tools on gantry 2 -- (the other tool has a different nozzle diameter, so can't include it in duplication mode) but I love how simple it was to setup and it worked the first time I tried it - both X an Y axis mapping in duplication -- really great.
