x and y will not home onle z axis moves when you home all axis please help on a 300x300x400 cartesian.

wont let me upload anything telling me its flaged as spam by askmet.com im lost?

oh ok i see what your saying and thank you so much for all the help i cant tell ou how much it means i been trying to get it right for a week. ill post how it goes and thanks again

hi,
I'm fairly new to RepRap and I'm having issues with my printer wanting to run at the top of my z axis and not an z home here are my files if they help. any help would be appreciated

Ok that was my thought as well. I'm in the process of going dual z leads so I'm just waiting on new leads then I will know for sure. I don't need to change any settings for dual z correct? just wire in place of z jumpers and good to go from my understanding? or am I'm I mistaken? and thanks for taking time to answer all my questions

ended up it was in my cura gcode there was some marlin in there and once deleted its been running fine now thank you again.

@phaedrux ok great thank you i have the Cura fixed but I'm having issues with my z steps like u said. my problem is I have a longer lk1 lead screw that's 8mm and I cant find any info on it so I'm quite sure its wrong. an ideas were I could start to calculate them correctly or how to identify my lead screw?

i think i figured out the issue i disabled axis limits and adjusted trigger hight and re zero z axis and it seems to be working but my cura code is causeing a auto level before each print can anyone see mistakes in it that i posted?

and im runnind duet 2 wifi and rrf 2.2 and web 1.26

@arnold_r_clark my bl touch all works perfect but here is home all```

anything else you can think of?

thank you I got that issue figured out and I'm on to another issue unfortunately but thank you for your response.

hey guys I'm having some issues and don't know what to do. i can home my printer fine and run mesh bed leveling and every thing but every time i go to print it runs straight in to my bed and when I compensate for that with babysteps on layer 2 it jumps up like 5mm for second layer on print and i don't know what could be wrong. i will add my config and a example print to see if maybe someone may be able to help I'm running a longer lk1 its a 300x300x400 Cartesian. thanks in advance.```

undefined[NEW BLTOUCH GODE DUET.gcode](/assets/uploads/files/1629986504957-new-bltouch-gode-duet.gcode) 

so i got it to all work and ran my bed calabrations but when i run a print z axis homes then raises and drops back down in to my bed on the second drop. i have a 30mm x off set for bl touch and it works on the first home do you think i need to put in another offset for the second drop? any ideas were to start?

home all and my home z and retract in that order
