Z homing issu whit endstop please help

bartekp

Hello Guys , I try to not give up but duet still win with me , My issue is that in my corexy Z lift not responding with Z endstop . My printer is Tronxy x5 sa
When I make homing Z the axis move and not respodning to z stop switch ,and even I make M119 And make test and show me result as At min stop by Z axis if I push z stop switch . But when homing just go high as Tank to brake eveything
My qyestions for this topic ar
If I have two motors on Z axis do I need two zstops? If yes where to connect seccond ?

Is the posibility that I ahve bltouch sensor and he made the problems with Z stop ??

The switch led on the duet next to Z cable socket responding to using z switch .

@bartekp where is your endstop situated? your config says at minimum (i.e. 0) but your homing file for z sends the axis to the maximum.
I don;t have z endstops on any of my machines and just use a probe to home the z axis

bartekp

@jay_s_uk THe Z endstop is at the top and to homing Z the table is liftet to top

jay_s_uk

@bartekp then your homing file needs changing
e.g.

@jay_s_uk In exosted with this config , can you tell me wah to do start printing I try to understatnd but this manual iw writen by enginer who maded this and I mnot so smart like he . And I fight with this almost 3 weeks .If you can please tel me what to change
Bart

bartekp

@bartekp I try to change Z1 to Z2 or S1 to 0 or 2 and the sama results

bartekp

@jay_s_uk I changed the home z and nothing changed

jay_s_uk

@bartekp it should change the direction it homes in when using just G28 Z or Home z on the DWC screen.
Otherwise ditch the endstop and move the head to the middle of the bed and probe using G30

bartekp

@jay_s_uk G28 table go up but whit G28 Z table goes down and when I pusch Z endstops the table stops

bartekp

@jay_s_uk im not sure if my Z probe is good code in config g

jay_s_uk

@bartekp sounds like your z motor need inverting then. As Z0 should be when the bed is in its highest position. Change the S value on the M569 line in your config to either S1 or S0.
Then reboot and home x, y and z independently and see if it's in the right position. DWC should show 0 for z once homed

bartekp

@jay_s_uk OK I inverted the Z motors works bether!
What I meand that when I pusch X home or Y home table move down and home this axis and back to position , and after this i must homing Z what work also perfect
but If i Puch home all axis table go down and down and down and I must restatr the maschine

jay_s_uk

@bartekp edit the home z portion of homeall to match the same as in homez.
If you're not sure, post your homeall here and I'll edit it for you

There you go

@jay_s_uk HI You mean G92 adjust for z 100 like this ??

@jay_s_uk HI You mean G92 adjust for z 100 like this ??

Can you look at Z probe if is good generated ?

what type of probe is it?
you can check the status of the probe on this window

If its red, its triggered, if its not red, its not

@jay_s_uk Bltouch sorry for that
