i think this has been covered already but worth a remention as my A350 shipped with the extruder E value of 212.21 and it needs to be 249.65 This is quite a 15% inaccuracy and results in significant under extrustion. Quite suprising the Snapmaker team didnt catch this in QA testing. Hopefully they will ship future units with an updated E value to save novices a lot of hassle. Infact id just say change it to my value by connecting via the Serial USB (not WiFi as you wont get the data) Maximise the Console window in the Luban Workspace. Type M500 and note that the M92 line is likely to have E212.21 at the end… Type M92 E249.65 and press enter . Then type M92 and press enter to notice the value has changed to be E249.65 then press M503 to update the firmware and permanently store the new value

I have my estep calbrated preceisely but overextrude quite a bit regardless of that. what I think works the best is using the slicer flow calibration on this site to come up with a good flow rate, it helps a lot with precision for me personally… Teaching Tech 3D Printer Calibration (teachingtechyt.github.io)

I calibrated mine cold. I think the best is to calibrate it cold, and use flow configuration on nozzle, temp and material change.

[image] Slynold: I calibrated mine cold On bowden extruders it is the way to do it, only the extruder is calibrated. Is it on direct extruders the same or not? What are you guys (and perhaps girls?) thinking about?

Is there a terminal program that can be used on an Android phone to connect to the Snapmaker printer? It would be so much easier to connect to my phone than to try to haul a computer to my printer

[image] AutoCalibration Not Working Snapmaker 2.0 First, my understanding is the light is always on… it does not indicate a trigger… Second make sure the probe is over the bed… some people have had issues with gouging because the sensor is not actually over the bed even though the nozel is… Third, and mostly as a side note… if you have an OTG cable you can download 3dfox and connect the printer to your phone for console commands… that way your printer does not need to be near a pc.

I tried typing the codes and the console didn’t respond at all. It never should any M92 lines or anything including any data other than the help information. Any help that can be provided would be greatly appreciated.

I too can attest to this. Out of the box my a350 was 212.21, and it calibrated to 248.78.

I got different results with different speeds - what’s the best speed for calibration?
