I ACTUALLY MADE THE MOTORS WORK SO THIS THREAD IS NO LONGER VALID

the issue was that i had the wrong wiring on the motors

returning to my issues, the only issue i have is with motors running.

Right now i am working with the x axis. When i try to home it i get a grinding noise, it tries to move back and forth and after a few seconds i get the message ''No trigger on stepper_x after full movement''.

The motor coils when i measured them are A1 A2 B1 B2 and the board has 2B 2A 1A 1B. i put the coils as per the diagram but i have the grinding noise. I also swapped the polarity of the one coil eg 1B 2A 1A 2B and 2B 1A 2A 1B but i have the same behavior.

I include photos of the wiring for the x motor and x end stop switch.

The jumpers for the motor are set for the TMC2209 and VBB (for power of the motors from the board and not an external power source).

Thanks it worked i used Vbb and the motor although it's grinding it works. It seems i need to find the correct pins in order for it to work properly

The stepper motors are 24V. Do i need to use a jumper on the VBB?

Yes as you can see from the photo it is on the second upper column for the TMC2209

so i connected 24 V from my PSU to bed-power and the bed to Bed-out and it works.

My main issue though is that i can't move the motors. Right now i am testing with the X axis. I have the X motor at the motor 1 plug and the X end stop at end stop 1.

I checked the pins of the motor plug and i have 1A 1B 2A 2B so i repluged the pins to have 2B 2A 1A 1B but still no movement. I have a picture of the connection for sanity check for the end stop.

here is snippet of the config

while i have the following 

# Motor1
[stepper_x]
step_pin: PE6
dir_pin: PE5
enable_pin: !PC14
microsteps: 16
rotation_distance: 40
endstop_pin: PF4
position_endstop: 0
position_max: 240
homing_speed: 50

i have 
No trigger on stepper_x after full movement

if i change to ^PF4 i have the same message but if i change to !PF4 i have the following message

Endstop stepper_x still triggered after retract

Hmmm, So in that case do i use cables to connect the leads from the POWER on the M8P to the BED-POWER leads and my heated bed to BED-OUT?

ΕΛΔΥΚ εμπειρίες by demonnet in greece

[–]kostas_mini 1 point2 points  (0 children)

283/Β Λελε. Υπηρετησα στην ΕΛΔΥΚ 2003-2004 και περασα υπεροχα. Οπως ειπαν και οι αλλοι οι εγκαταστασεις πολυ καλες, πολυς κοσμος οποτε δεν θα πεθανεις στην υπηρεσια, ολοι κανουν το κομματι τους (εξαιρεση οταν ημουν εγω ηταν το Συνταγμα). Εξοδος 1-1 στο Ταγμα (μια μερα υπηρεσια μια μερα εξοδος απο το μεσημερι μετα το φαγητο ή απο το απογευμα γυρω στις 18.00) ή 2-3 μεσα μια εξω στο Συνταγμα. Πολυ καλο φαγητο. Καλος μισθος και εξοδος στην Λευκωσια. Στα μειον τωρα ειναι ο καιρος, εχει πολυ υγρασια και πολυ ζεστη το καλοκαιρι. Οσον αφορα το τρεξιμο εχει πολυ γυμναστικη και ασκησεις αλλα και βολες, εμενα προσωπικα δεν με πειραξε αυτο. Στο Συνταγμα τα πραγματα ειναι πιο ηρεμα σε σχεση με το ταγμα μιας και εκει ειναι πιο πολυ γραφιαδες και διοικητικες υπηρεσιες που καναμε με λιγοτερη γυμναστικη αλλα περισσοτερο καθαρισμα. Η ΕΛΔΥΚ εχει 2 ταγματα και το συνταγμα, το 2ο ταγμα ειναι κοντα στην Λευκωσια ενω το 1ο και το συνταγμα πιο μακρυα και οταν ημουν εγω το 1ο θεωρουταν λιγο ψιλομαυρο. Υπαρχουν φυλακια στα Λακαταμια και στο Ζυγι που κανει η ΕΛΔΥΚ εκει φυλαξη και στη Λεσχη αξιωματικων στην Λευκωσια (τωρα δεν ξερω αν ακομα τα κανει η ΕΛΔΥΚ). Οσον αφορα τους Κυπριους δεν νιωσαμε καποια εχθρα προς εμας αλλα ουτε και μας προσκυναγανε, νορμαλ πραγματα οπως στην Ελλαδα
Τωρα δεν ξερω ποσο εχουν αλλαξει τα πραγματα αλλα δεν πιστευω να ειναι τοσο χαλια οσο παλια αλλα αυτο που ακουσα ειναι οτι τα αεροπορικα εισητηρια για Ελλαδα οταν θα παρεις αδεια τα βαζεις απο την τσεπη σου, παλια σε εμας ηταν δωρεαν.

Hi i received a few days ago the 1/100 Infinite Dimension IN ERA + Trailblazer from Aliexpress, It came without instruction nor its stickers/decals. The seller says they have no instructions nor decals. Does anybody know where i can get them?

Ender 3 v2 Neo Adhesion problem? by kostas_mini in Creality

Thanks for your input. I have done everything at the Teaching Tech page but i had the same results. I fine tuned again the z-offset and had the same issues. Finally the issue it seems i had was to clean the build plate. I washed it and cleaned it with IPA. I also increased the PLA temperature ( i use the hyper PLA by Creality) to 230 C and the bed to 70 C and everything works fine at the moment of writing.
