First Layer and Extrusion Problems
-
@CaLviNx Ok, i will test this in the morning.
I have 2 Linear Rails on z ( left + right in the middle ). The Leadscrews are ~ 6 cm in front of them

A very strange (to me anyway) arrangement for linear rails, in that you would expect 3 rails with three lead screws.
But if it works then happy days. Personally I always have x3 rails/lead screws and have the bed frame with a degree of articulation to allow the levelling to operate as it should, once you get it setup the levelling gives you great prints

@CaLviNx said in First Layer and Extrusion Problems:
G30 P0 X2 Y-2 Z-99999 ; Probe near the front left lead-screw
G30 P1 X152 Y278 Z-99999 ; Probe near the rear lead screw
G30 P2 X290 Y-2 Z-99999 S3 ; Probe near the front right lead-screw
M671 X425:200:-25 Y240:-25:240 S1 ; leadscrews at front left, rear middle and front right
how are these points near the leadscrews?
-
@CaLviNx That´s how this kit is designed. Eventually, I will change it to a kinematic mount without the 2 Linear Rails like the HevOrt. At the moment I have a battle with my E3d Volcano... it is constantly clogging and I don´t know what
I´m doing wrong... trying to print PLA with ~ 205 ° Nozzle and 60° Bed. -
@Veti i have this settings:
M671 X425:200:-25 Y240:-25:240 S3 - position of Spindles with drives 2.3.4
and this are the spot i´m probing:
G30 P0 X330 Y250 Z-99999 ; Probe near the front left lead-screw
G30 P1 X165 Y0 Z-99999 ; Probe near the rear lead screw
G30 P2 X0 Y250 Z-99999 S3 ; Probe near the front right lead-screw -
is 0,0 not the bottom left of your printbed?
-
@Veti x0,y0 ls in my case the right, rear corner
-
I could only mount the Endstop on the left side of my carriage and the Y Endstop is at the back
-

thats going to be very confusing.
certainly because of that you got the offset of your probe wrong. -
@Veti should i change it ?

@Veti this is my actual drive mapping and endstop config:
M569 P0.0 S0 ; physical drive 0.0 goes backwards M569 P0.1 S0 ; physical drive 0.1 goes backwards M569 P0.2 S0 ; physical drive 0.2 goes backwards M569 P0.3 S0 ; physical drive 0.3 goes backwards M569 P0.4 S0 ; physical drive 0.4 goes backwards M569 P0.5 S1 ; physical drive 0.5 goes forwards M584 X0.1 Y0.0 Z0.2:0.3:0.4 E0.5 ; set drive mapping```;Endstops M574 X2 S1 P"!io1.in" ; configure active-high endstop for high end on X via pin !io1.in M574 Y1 S1 P"!io0.in" ; configure active-high endstop for low end on Y via pin !io0.in M574 Z2 S2 ; configure Z-probe endstop for low end on Z -
can you set 0,0 in your slicer to be top right? i just checked in prusaslicer and 0,0 is bottom left
-
@Veti i have to look. i used cura 4.8.0 at the moment. I didn´t want to spend money on simplyfy 3d bevor the new version 5 is released. Hopefully soon
-
@Veti yes, its possible. you can set high or low endstop positions in advanced printer setttings
-
@Frederik
my recommendation is to not do it. why do you think that is better? -
what could be the cause of this message :
G28 Z
Error: Z probe already triggered at start of probing move
Error: Homing failedi got this message on every 4th or 5th try to home z.
its a genuine bltouch
-
that sounds like a wiring probem
-
@Veti i tought, perhaps its the standard and would be better for compatibility or troubleshoooting reasons...
-
@Frederik
no the standard is 0,0 is bottom left. -
@Veti ok , one moment i will check it with my multimeter... could it be a bad crimp ?
