@tas Thank you very much.

@tas Could you post your wiring on both accelerometer and Duet and also what are you using for accelerometer for? Input shaping? If so, do you know if the Duet takes live input from the accelerometer and changes input shaping for each movement, also do you notice a significant improvement in print quality? Also, what is the boards orientation and what is your I value (for input shaping if you are using it, as mentioned here https://docs.duet3d.com/User_manual/Connecting_hardware/Sensors_Accelerometer)

Hello, I plan on installing this accelerometer to my 3D printer with a Duet 2 Wifi. I was wondering if this specific one would work and if it would be possible to use the in-built temp sensor and if the DSH version is worth it compared to sparkfuns DH, I plan on using it for input shaping. Also, in the docs, a ribbon cable is used, however, I though ribbon cables can really only be used for short distances and I have a Ender 5 Plus (500mm^2) and if there is any way to get around that.

@mrehorstdmd How tight should the belts be I'm using exoslide so I will reach out to him to see if any of the exoslide parts can cause this problem, also what are some areas where wobble might be common?

@mrehorstdmd I just finish printing my part with a .2mm layer and .3mm for initial layer with a .4 nozzle and line width of .4. I also added the motor line as @gloomyandy pointed out and reset my steps for motors to 80,80,800. Now, my print quality is better, but there are still some ridges however I noticed they only occur on the left side of the x axis (facing printer from front). The corner thing is still mildly present and then there are these lines on the surface of print (circled). The face of the part in the image you can see was printed in the back of the printer. I calibrated only E-Steps, should I calibrate flow as well?

@mrehorstdmd No it is just 800m/s no upstepping. So you are saying I set it back to 800m/s and I will be fine printing at 0.2 mm and 0.35mm as both of those are divisible evenly by 1.25um?

@mrehorstdmd I am was using 10000mm/s/s for acceleration in cura and 80mm/s for speed but I reduced it to 2750 for acceleration and 60mm/s for speed and I saw a little improvement. iam nost sure what pressure advance is.

@mrehorstdmd What is step multiples for layer thickness? What layer height should I be using for 80,80,800?

@gloomyandy Yes the values are supposed to be 80,80,800. However, I thought it was common practice to calibrate these values which is how I reached these values.

@mrehorstdmd My layer height is 0.2 mm and 0.3 mm for first layer.

@moth4017 The whole part has a rough finish it is just worse along the X axis and this problem seems to get worse the bigger the part is. A 20mm calibration cube has an almost perfect finish but anything bigger than that has a rougher finish. But yes, the worst side is always along the X axis.

@Phaedrux No, and I don't really want to because there are a lot of settings that would need to be changed and I'm not sure if it would behave the same.

@dc42 No the layers are just coming out at both sides of X axis it is not where one side overhangs and then that same layer is indented on other side. For example, at the bottom left side, it is pretty much perfectly smooth, but on the right side, only some of those layers are protruding. For some reason, one side of the X axis is always smooth while the other is only slightly rough. And also, at the corners, a part sticks out, "corner ridges". The first part shows the roughness, and the bottom shows these corner ridges that add to dimensional inaccuracy.

@TRATOON I also just noticed the dimensional inaccuracies are along the x axis, everything the y axis does is fine.

Hello, I have modified my Ender 5 Plus with a Duet 3 with an E3D Hemera and Volcano. I am getting a rough finish which looks unappealing and causes dimensional inaccuracy. I have leveled the bed, tensioned the belts, calibrated E-Steps, calibrated XYZ steps using calibration cube, and calibrated flow. With a maximum deviation of +-0.03mm, which is tolerable. However, I am still having poor print quality. I am attaching photos and have highlighted problem areas. My config.g:

How do I get a smooth finish and make it dimensionally accurate?

@dc42 What exactly would that command do? Also, I'm using E3D hemera direct drive are the 2 x 40 mm retractions too much? If so, what should my end Gcode look like the as soon as the print is done it moves to the corner, retracts all the filament out of the hot end, and then cools down?

Hello,

Whenever a print finishes, the head stops right above it and then moves in like a minute leaving a blob or melted spot in print. If I keep all settings the same and print in Marlin there is no issue, so my guess is that the firmware is causing something:

@Phaedrux My part cooling fan has + wire to out 1 +VOUT and the - wire to GND it's a two-wire fan.

@Phaedrux I have already tried increasing Q value (250, 10, 5000, 1000, 10000, 100000, etc.) I have tried a known good fan, still 100%. I just read this post https://forum.duet3d.com/topic/18350/duet-toolboard-fan-issue and the user had a similar problem they said that they put their fan on the PWM pin. Right now, I have a two-wire fan on out 1 connected to GND and VOUT is this correct or do I switch wiring.

@Surgikill have you had any issues with your print cooling fan? Mine seems to always be running at 100% and doesn't responds to off/slow down commands.
