@Phaedrux Is it possible to connect Z max endstop to E1 stop connector? How to define it?

Phaedrux

@agniusm I'm not exactly sure. I've never done that before. My Z probe uses the probe connector, so the Z endstop is free for my Z max switch.

I don't think you would have to do anything to specifically define it other than to say you have a Z max endstop, then in your homing files you will need a G1 S1 Z+ move to seek the endstop. But I could be completely wrong. @dc42 would have to give you an exact answer.

https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_Set_endstop_configuration

M574 Z2 S0 ; Set active-low switch at the high end for Z Max.

Are your switches active-high or active-low triggers?

Agniusm

My z endstop is polulated and e0 is for filament runout If I remember correctly, switch I want to use is NC. I thought I need to assign e1 endstop to z max but I found no hint in wiki.

dc42

What do you want your Z Max endstop to do when it is triggered? if you want it to carry out an emergency stop, you can do that by connecting it to the E1 endstop connector and using the M581 command to assign a trigger action to it,

Phaedrux

@dc42 what if you want to use it as a zmax endstop but connected to the e1 endstop? Can endstops be defined in software?

Agniusm

@dc42, i want to use it for rehoming Z after powerloss. My gantry is heavy and it sags some.
But yes, as @Phaedrux i too would like to know if its possible to reassign endstops.

In that case, in your home-after-power-loss script you can use M574 Z2 S2 to select Z probe as the homing switch type, M558 P4 to select switch Z probe, and use G91 G1 S1 Znnn to home Z. Then use M574 and M558 to reset the homing switch type/position and Z probe type back to normal.

Reassigning endstop switches is not yet possible but will be implemented soon.

@dc42 Should i use M116 after resetting Z probe type commands in "home-after-power-loss script" and before changing it back to normal commands?

You need to use M116 somewhere in your resurrect-prologue.g file, to make sure that the heaters are up to temperature before it completes.

So i am back at mesh mapping and my inconsistent first layer accross the bedoinI might be doig it wrong.
My induction probe is offset on x axis by -24.5mm only and inline with the nozzle on y.

Do i need to position the nozzle where i want to probe or do i need to position the probe where i want to probe?
I am homing with probe and at the moment i do that at x10 y10.
Would probing at the bed center improve accuracy?

dc42

In general, when probing you tell the firmware where you want to probe, then it uses the declared XY probe offsets to put the probe where you specified, not the nozzle. The exception is a plain G30 or G30 S-1 move, which probes wherever the head currently is.

When using a Z probe to home Z, it is best to probe at the centre of the bed, because any print do is likely to use that area of the bed.

@dc42, swapping wifi for eth module, would i need to put eth firmware first or after swap?

Assuming you are using a recent firmware release, both run the same firmware file (Duet2CombinedFirmware.bin).

@phaedrux, can you post your HomeZMax.g script? I got Z max installed on Z endstop input and after power loss it slams into my bed. I have something incorrect.
Thanks

Phaedrux

@agniusm Here you go

; HomeZMax.g
; Called to home Z to max endstop
;

M291 R"Are you sure?" P"Press OK to Home to ZMax. Or Cancel to abort." S3
M574 Z2 S1			; Set active-high switch (Opto) at the high end for Z Max.
M98 P"0:/sys/ZSpeedsZMaxHome.g"		; Load slower Z Speeds profile
G91				; Relative positioning
G1 S1 Z330 F300			; Move bed down until endstop triggers
G1 Z-5 F100			; back off 5mm
G1 S1 Z10 F100			; go back to trigger endstop more slowly
M98 P"0:/sys/ZSpeedsNormal.g"		; Load normal Z Speeds profile

Agniusm

@phaedrux Thank you.
I think i am missing something. I have not specified exact Z max distance. would that be the case?
How would you calculate exact one? I have induction probe for z min and a micro switch for z max
My induction is connected to E0 endstop and Z max to Z endstop

Phaedrux

I have another macro that lets me adjust the trigger height of my optical endstop. It could also be used to measure the exact distance and set the axis limit. I'll post that later today.

@dc42
I have replaced my duet wifi with eth. What procedure i should follow to get firmware working?
I had latest duet firmware, updated prob 3 weeks ago.
Thanks

What firmware is the new board currently running? If it's at least 2.0 or newer you can upload the single combined zip file as is and the duet will extract the firmware files and update everything as needed.

Otherwise, the usual procedure here should work: https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware
