OctoPrint with Geeetech A30 problem

Get Help

hallo,
ich habe octoprint mit meinem geeetech A30 drucker verbunden. Da die Fördermenge meines extruders überhaupt nicht stimmt möchte ich den Befehl M503 eingeben um E zu ändern. jedoch passiert bei mir nach der Eingabe von M503 garnichts... es wird folglich nichts angezeigt... kann mir jemand erklären wie ich das ändern kann?

Hi,
sorry for my bad english. I just connected my geeetech A30 with my raspberry pi including octoprint. after i got a big problem with my extruder i figured out why my printer still wont print correctly. if i extrude 100mm filament it is acually 125mm so der is an over extrusion. when i want to change the E: setting with octo i know i have to give the order M503, but when i do this nothing happens there comes no information or no possability to change E: maybe someone can tell me why i cant change this setting
thank you

This is Geeetech's webpage for how to do this. But this looks a little complicated.

It may be easier to install the EEPROM Marlin Editor plugin, then use it to set just the "steps/mm" setting to something lower.

Your ratio appears to be 125/100 which is too much. But you can also think of this as 25/125 (20%) which needs be be lowered from the existing setting. If the current setting is 866.69, for example, the new value needs to be 866.69 * 0.8 = 693.35 in order to be close-to-perfect.
