Confused after FW upgrade to 3.3

chefffe

Hi,
I went from 2.02 to 3.3 and messed up my whole System. I used the config tool but I cant get my motors and endstops to work properly. I have a CoreXY which worked fine before but now with the new config when I try homing it doesnt work for any axe. Pressing Z home results in driving Z5mm up and stops. Pressing X home results in driving Z 5mm up and stops, the same is for Y. In the console I can read failed to enable endstops. Dont see what might cause this issue.

config.g:

@chefffe said in Confused after FW upgrade to 3.3:

M574 X1 S0 P"xstop"

Change S0 to S1. Same on the Y axis.
Then check again using M119

chefffe

@jay_s_uk
This is also weird.
M119
Endstops - X: at min stop, Y: at min stop, Z: at max stop, Z probe: at min stop
Homing X results in Z driving 5mm up then 5mm down and x only drives only few mm before it stops. x coordinates are always showing zero. The same is for Y. Z is unchanged, stopping automatically after driving 5mm.

jay_s_uk

@chefffe then you need to invert your endstop signal. Add a ! to the xstop and ystop names, like Z.
Also check the endstops by manually triggering them and sending M119 at the same time

chefffe

@jay_s_uk
Thanks a lot, this was a good step forward. Now the X + Y Axis move fine, also the Z one but there are still issues.
When homing all Axes the head is driving diagonal to the 0 position (which is normally fine but I need first Y home than X home to hit my endstop switches).
The 2nd issue is when I home Z, it stops at Z Endstop but when I afterwards press X-home then the Z-axe is going 5mm higher and press the printhead :(). Looks like the board "forgets" that it was before already in Z-End.

jay_s_uk

@chefffe you'll need to modify your homeall to home Y first and then X rather than them both together.
You might as well post your homeall and homez files

chefffe

@jay_s_uk
homeall is in post1. Here is the

Is it enough to delete:
G1 H1 X-295 Y-255 F1800 ; move quickly to X or Y endstop and stop there (first pass)
and move Y before X in the list?

jay_s_uk

@chefffe looks like your Z axis is moving the wrong way

M569 P2 S0                                     ; physical drive 2 goes forwards

change the S0 on that line to S1

Give those a whirl

chefffe

@jay_s_uk
With that change the homez.g works. The homeall works as well but when I try to move Z after homing the movement is reversed. I assume I need to reverse the Z motor again?

jay_s_uk

@chefffe
where is your endstop at? zmin?
you should use + movements to move away from the bed or bed away from the nozzle and vice versa

chefffe

@jay_s_uk
My Z Endstop is at the top end close to the nozzle. When triggered the bed should only be able to go down (-).

This is current state:
M119
Endstops - X: at min stop, Y: not stopped, Z: at max stop, Z probe: at min stop

When I press - I expect the bed going down, with + up. The Z-Endstop ist an optical, which is normally on (off when triggered).

This is my homeall.g from the old configuration running fine:

G91                     ; relative positioning
G1 Z5 F6000 S2          ; lift Z relative to current position
G1 S1 y-255 f3000

G1 S1 y-255 f360

G1 S1 x-295 f3000
G1 x5 f3000
G1 S1 x-295 f360

G1 S1 z-245 f3000
G1 z5 f3000
G1 S1 z-245 f360

G1 S1 X-295 F360        ; move slowly to X axis endstop once more (second pass)
G1 S1 Y-255             ; then move slowly to Y axis endstop
G1 S1 Z-245 F360       ; move Z down stopping at the endstop
G90                     ; absolute positioning
G92 Z0                  ; set Z to axis minimum (you may want to adjust this)

This the old homez.g.

```

G1 Z5 F6000 S2    ; lift Z relative to current position
G1 S1 Z-255 F1800 ; move Z down until the endstop is triggered

@chefffe to move your bed away it should be a positive movement, not a negative movement

chefffe

@jay_s_uk
I see that in my old config.g the Z axe was also configured like you said:
M569 P2 S1
Maybe I mix now something up.
I set the Duet up about 3 years ago and forgot a lot shame on me ...
I will print later on something, then its clear. Many thanks for now!

chefffe

@jay_s_uk
After "playing" a little bit around I end up now that homing works fine ... but ... after Z homing the Z axe is only moving in minus direction (up towards nozzle) and not in plus direction (down away from nozzle). I couldnt yet find what could cause this ?
The Z axe stops every plus movement after leaving the Z Endstop.

dc42

@chefffe what M574 Z command are you currently using in config.g ?

chefffe

@dc42
Hi, it is ->
; Endstops
M574 X0 S1 P"!xstop" ; configure switch-type (e.g. microswitch) endstop for low end on X via pin xstop
M574 Y1 S1 P"!ystop" ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin ystop
M574 Z2 S1 P"zstop" ; configure switch-type (e.g. microswitch) endstop for high end on Z via pin !zstop

When I add the ! to Z I get an error that the endstop is not working. The endstop type is an optical which is normal "on" and triggered "off".

jay_s_uk

@chefffe change the Z2 to Z1

This did the trick!! I am very happy, Great Forum thanks again!
