E180 Under Extruding?

[VooPoc]

Hi Guys,

FYI I'm new to 3d Printing.

I was looking at calibration to improve prints on my E180 and I've done a 100mm extrusion test and it's short my 31mm so its only extruding 69mm.

Some of the tutorials I have watched use code M501 to show parameters, which doesn't work. Does anyone know how I can calibrate the E180?

Thanks,

Maybe you should properly increase the A4988 driver board voltage(Normal is 0.8-1.1V)

If you use cura for slicing, you can increase the filament flow in the setting

Thank for this, I will look into it and check the voltage. Is there any means to do this via firmware and gcode gets and sets (or whatever they are called in this language).

I think you can try to print a 20MM cube, and then see the size is normal, in order to determine whether the normal extrusion

Hi Willam,

Is it possible to ask your admins to install a plugin such as "image upload" on your phpBB deployment?

I cracked open the bottom and noticed the Z_A1, Y_A1, X_A1 clustered together. The E2_A1 is separate and I assume needs tweaking. I am disappointed that this isn't a function via firmware or even Gcode.

Before I play around with any of these physical settings can you confirm there are no other means of calibration?

Thanks,

You can upload the pic to Google drive,I will check it at first.

Hi William,

The stock voltage I have on the E2_A1 was 0.46v and when I increased the voltage it made no difference to the extrusion length, it does appear to have increased the speed, but not the steps/mm. Additionally, when I increased the voltage to 0.93v the motor started to make a tick sound and jitter.
Therefore, reduced it back to 0.46v.

Any ideas?

Thanks,

I use "SSCOM 4.2" and send "M2002 E * \ R \ N" to change steps per mm

I think you might need to provide a little more info?

I have done a search on SScom and it appears to be a debugger tool. I have however executed M2002 using pronterface and it outputs what I'm looking for. Is there any documentation on using M2002? I want to know what I'm executing and "E * \ R \ N" isn't self-explanatory.

Thanks,

ok

Default steps per mm of extruder value is 65 (E65)
