home z bug fix

jay_s_uk

@Adamrobot so yes, your switch on your printhead it setup as a probe so you should be using G30.
I would also suggest you look into upgrading from RRF2 to RRF3

@Adamrobot said in home z bug fix:

When you did the M119 and got this back:
Z: at min stop, C: no endstop, Z probe: at min stop

Was the endstop/probe touching the bed, or were you triggering it? If not, then you need to invert this in M558 in config.g, ie change I0 to I1:

M558 P7 X0 Y0 Z2 H3 F360 I1 T20000 ; Set Z probe type to switch, the axes for which it is used and the dive height + speeds

@droftarts @jay_s_uk
Hello jay and mr administrator,

After implementing your suggestions, part of the home Z function succeeded. However, I need to manually move the printhead above the Print bed position before I run home Z. When I use the home Z command directly after homeX and Y, although the dashboard shows the Printhead's position as 150 and 100, it is actually still in the bottom left corner. In this position, the print bed cannot reach the probe Z sensor.

now im using RRF3

the home Z code:

; homez.g
; called to home the Z axis

M98 P"/macros/Coupler - Unlock"	; Open Coupler

G91 							; Relative mode
G1 H2 Z5 F5000					; Lower the bed
G90								; back to absolute positioning

G1 X150 Y100 F50000				; Position the endstop above the bed centre

M558 F1000
G30
M558 F300
G30

@Adamrobot maybe F50000 is just too fast. Try something slower. Maybe take a 0 off

Adamrobot

@jay_s_uk @droftarts
Great it works!

and a followed question: When I attempt to heat the nozzle, it shows that the M568 command is no longer needed. I referred to other posts on forums, and they suggest the issue might be a mismatch but I believe I have installed the latest firmware version for the Duet 2 WiFi/Ethernet. Could there be another reason for this issue? or anywhere wrong?

RepRapFirmware for Duet 2 WiFi/Ethernet version 3.2.2

M568 is supported from RRF 3.3. An older version of the command was supported up to RRF 1.18.

RRF 3.2.2 is not the latest version. RRF 3.4.6 is the current release; download the large zip file "Duet2and3Firmware-3.4.6.zip", without unzipping it, from https://github.com/Duet3D/RepRapFirmware/releases/tag/3.4.6
In DWC, click System > Upload System Files and upload the ZIP file to the Duet. This should update the firmware, DWC and probably the WiFi firmware.

@Adamrobot Is it just heater 4 that can't tune, or is it a problem for all heaters? What command are you sending to tune the heater? What does the graph look like when you tune that heater, and is it different from the other heaters if their tuning succeeds?

Ian

Adamrobot

@droftarts I attempted to tune heater1 and heater4, the Command is M303 T0(T3) S200, and the result was the same, both heaters can only reach a maximum of around 150 degrees, and the heating will stop and in Console shows tune canceled.

the temperature is as follows

droftarts

@Adamrobot From your M122 report, you are running this machine on 12V. Are your heaters 12V? I think they are 24V heaters, which will not get to temperature on 12V.

Ian

Adamrobot

@droftarts
Hello mr administrator,

If it's an issue of insufficient voltage, can I adjust the voltage of the heater on DWC? Or do I need to replace it with a higher power supply module?

DIY-O-Sphere

@Adamrobot
This has nothing to do with a problem in the power supply unit.
You have to check whether the heating cartridge is made for 12V or 24V.
Either check the marking on the sleeve or measure the internal resistance.
In general 24v supply voltage would be an advantage. However, you then also have to replace the heating bed and maybe the fans.
