MIgration from RRF2 to RRF3 problem commands

[alil2096]

@dc42 Yes, that's the problem!! Endstop Y is "trigged=true".

Wiring is ok, How I can invert the logic? Because if I change the S1 in S0 or S2, then I have "1=null" in Object Model Browser..

[dc42]

@alil2096 does it go to "not triggered" when you press it? If it doesn't, then you have a wiring issue.

[alil2096]

@dc42 yes, it does

[dc42]

@alil2096 in that case, assuming your M574 commands in config.g are still as you posted earlier, your endstop switch is wired as normally-open, which is odd because your RRF2 config was for normally closed. Did you change the connections to the endstop switch? We recommend normally-closed.

[alil2096]

@dc42 Absolutly no change of wirings.. and yes, all my endstops are in NC mode..

When I push the micro, the status change from "trigged=true" to "trigged=false"

[dc42]

@alil2096 please post your config.g file exactly as it is now.

What is not clear to me is why with the same configuration (same parameters), with RRF2 everything worked fine and with RRF3 the axes of the motors are reversed and the Y endstop is not recognised and the mdriver map is wrong.

Could there be some sort of cache to clear?

[droftarts]

@alil2096 your M569 commands for X and Y have different S parameter values in your RRF 2 config. Change them in the RRF 3 config.

I think your y homing macro is wrong. You have all endstops set at the minimum end, but the Y move is to the maximum:

G1 H1 Y345 F1800 ; move quickly to Y axis endstop and stop there (first pass)

You haven’t posted your homeall to compare it with.

You can invert endstop logic using ! in pin name, eg M574 Y1 S1 P"!ystop". Though I think there is a wiring problem causing the inverted behaviour. The firmware does not invert just the Y axis by default!

@droftarts

**I think your y homing macro is wrong**

THATS'S RIGHT!!!

With the new RRF3 the macro is that of the configurator, which was different from my RRF2.

Now I've modify the macros and X and Y work fine!!! I've copied the old macro in the RRF3. Easy.

Now for Z axes: I've two motor, this is the old configuration (RRF2):

; homez.g
; called to home the Z axis
G91						; relative positioning
G1 H2 Z-1 F250			; lift Z relative to current position
						; split Z motor control to Z and U
						; for it to work we have to show U (param P4) in the UI
M584 Z2 U3 P4			; show U dirver
G1 H1 Z410 U410 F500	; move Z down until the endstop is triggered
M584 Z2:3 P3			; hide U driver
G92 Z410				; set Z position to axis minimum (you may want to adjust this)

And now is the new (RRF3):

; homez.g
; called to home the Z axis
;

G92 Z410         ; set Z position to axis maximum (you may want to adjust this)

;G91             ; relative positioning

;G90             ; absolute positioning

I've read that in RRF3 is no longer necessary to split the motor, that's right?

EDIT:
resolved also the Z axes. I've follow this guide:
https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors#Section_In_RepRapFirmware_Num_3

(in the bottom of page), and now my zhome.g is:

@alil2096 you seem to have a Z probe configured, so you can use that for Z homing rather than endstops. You could move the endstops to the maximum end of the Z axis, so that the printer can recover in the event of a power loss, without having to home the bed in a way that may cause the hot end to hit the print.

You can use the Z probe to level the bed, rather than the endstops; see higher up the page you linked.

Another problem with homing...

When I use the "Home All" command, i've the error "G28 Error: G0/G1: insufficient axes homed", while if I use the single home buttons, I don't have this error.

Therefore, when a try to lunch a job with the start G-code only "G28", the print fails because I0ve se same error..

Here my HomeAll code:

Any ideas?

It's a corexy so your homing file needs a slight modification to work correctly. Right now you're moving both X and Y at the same time to the endstop, and when the first one strikes, it stops both. Then you ask it to back off both, but one of them won't have been homed yet.

Try this

; homeall.g

@Phaedrux Yes, the problem was there.

For those reading this, I solved it like this:

; homeall.g

G1 X5 F1800					; go back a few mm
G1 Y5 F1800					; go back a few mm
G1 H1 X-395 F360			; move slowly to X and Y axis endstop once more (second pass)
G1 H1 Y-345 F360			; move slowly to X and Y axis endstop once more (second pass)
;G92 X0 Y0
G1 H1 Z410 F1800			; move Z up until the endstop is triggered
G92 Z410					; set Z position to axis maximum (you may want to adjust this)
G1 Z-5 F1800				; go back a few mm
G1 H1 Z410 F1800			; move slowly to X and Y axis endstop once more (second pass)
G92 Z410					; set Z position to axis maximum (you may want to adjust this)
G90							; absolute position

The single code are then reported in the single axes home files.
