I have had an Ender 3 v3 SE printer for about a month now. I’ve done some printing already and generally everything works fine. A couple of details are worth noting though:
the Auto PID option works fine initially, but when it gets to the end it signals that the bed temperature is too low, the system locks up, starts squealing and the only thing to do is to turn the power off. I don’t know if this is my mistake or the programmers. If even the temperature is too low - it should probably signal this error and leave the initiative to the user.
What do the two icons in the middle column (between the temperatures and the fan and Z-offset) mean. The manual does not explain this.
What does the option “disable stepper” actually do .The manual does not explain this either.
In my opinion, it would be nice to have an option to disable that loud beeper; the control would probably be secure enough without it. On the other hand, I think an audible indication of the end of printing would be useful. I think this would not be particularly difficult to improve in the next firmware version.
Another CEV3SE user here, mine is two months running.
Any specific configuration, never seen this on my prints.
% of Speed velocity and % of Extrusion
It ammm… disable the stepper motors So you can move manually the axis if you want. For example depending on how your code finish a Job the bed goes upfront and could be locked there. If you want to move it back by hand you select first that option to do it
You can add the beep in the end Gcode of your slicer too.
Re.1 I had no configuration. There was only SD in the printer and I wanted to see what this Auto PID was really doing. And then it behaved as I described.
Re.2a I don’t understand. Isn’t “speed” and “velocity” the same thing? What does it actually mean in this machine?
Re 2b Also unfortunately I don’t understand. This icon always shows 100% - even after retraction when there is no filament at all.
Re 3. Clear. Thanks.
Re 4. Good idea. As far as I know this machine uses the G-code Marlin “dialect”. But there I didn’t find the command to disable this beeper either. BTW. Where can I find the G-codes accepted by this particular machine?
Following your suggestion, I decided to add a sound to the gcode to signal the end of printing. Somehow it works, but strangely. I added the following sequence at the end of gcode:
M300 S220 P1000
M300 S440 P1000
The effect is that the machine makes two sounds with the same frequency. Furthermore, if the duration of the sound and the pause is shorter (for example, 200ms; I have done various experiments) - the machine does not “notice” this at all. Therefore:
where and what mistakes am I making (if it is my mistake)?
where can I find a list of gcodes and mcodes with their interpretations by this particular machine (not a general one - such as Marlin for example)?
Thanks in advance, Marek.
