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

Definitely using the latest firmware, yes. The odd thing is that the third machine is my personal one, and I also use Wi-Fi. But it did take a while before I got real data and not just an OK. The other two machines just keep giving me the same thing. I will connect via USB and see if that works. Thanks.

Try upper case M sorry, need to post over 20 characters so force to talk sh***

Thank everyone so much!! I was having the worst time and thinking of getting rid of this thing! From the actual steps to the cleaning hot end/nozzle and saying there should be a tube in there. Mine fell out and I thought all was lost. One question left. I was not able to get this to work with a F050 (the code I saw from the ‘original’ steps). I calibrated with F200 and got it within 0.1mm (need better calipers, I know). Should this E step work for any speed? even 25mm/s? Looking to print a few minis and want to use what I have before investing in resin. Thanks again!

The instructions posted much higher in the thread gave the F300, I also found that this number gave inconsistent result. Slowing down to F100 gave perfectly repeatable results and I was able to calibrate the steps that way.

I can’t find the instruction, could anyone send me a link? Best wishes, Jane, graphical designer, Work Time

Can this be done over wifi in the meantime?

@Wellnice No, I did it few weeks ago, and you still have to connect it with usb.

Extruder calibration result for new extruder: E237.50 extrudes exact 100mm of PLA Filament at 215C° - I did several tests to confirm this value. Slicer Flow still needs to be set to 88% in cura to get reasonably accurate prints.

How to do this with new firmware 1.15.3 (supports dual extruder) I now see this line when running M503 M92 X160.00 Y160.00 Z400.00 B888.89Current E212.21, BACKUP SINGLE E212.21BACKUP DUAL E667.22
