noob help dule z setup

@mobietec Sorry, should have remembered this before; see https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe#Section_Duet_Num_3

Connect the BLTouch to IO_7 ... It's also possible to use IO_4 or IO_5 instead of IO_7.

(Edit: I've updated the text on the wiki to make it clearer.)

You can't use IO_3!

Only IO_4, IO_5 and IO_7 are PWM capable, so able to control a servo (like the BLTouch). See table here for IO pin capability: https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Hardware_Overview#Section_IO.
Use one of IO_4, IO_5 or IO_7 instead. So, with the BLTouch connected to IO_4, your config.g should be (which is what you had earlier):

; Z-Probe
M950 S0 C"io4.out" ; create servo pin 0 for BLTouch
M558 P9 C"io4.in" H5 F120 T6000 ; set Z probe type to bltouch and the dive height + speeds

Also, this line is incorrect, and may be interfering:

 M574 Z2 S2 C"io4.in" ; configure Z-probe endstop for low end on Z

Are you wanting to use the endstop on the high end (as in where Z value is 'high', with the bed furthest from nozzle, so bed at the bottom of travel)? That's what 'Z2' means. Though 'S2' means probe not endstop, and the 'C' parameter is wrong (should be P). To set it up correctly, see https://duet3d.dozuki.com/Wiki/Gcode#Section_M574_RepRapFirmware_Num_3. For now, change it to:

M574 Z0 ; No Z endstop

Make these changes, test and post your config.g.

yipeee got the bl working

now got to work on bedsize and bed mesh because it probs outside
of bed aeira

Oof! that was on the tip of my brain yesterday.

Mobietec

@phaedrux yep duet well my board only bl on duet 3 io7 will not work on any others strange
i can now prob bed do a mesh level etc

now for next problem

need to figer out how to dule z level

Mobietec

@mobietec Thank you every one who is trying to help me

Mobietec

@droftarts thank you i was thnking do i need to probe more than once im ow using a gen bltouch or is just 1 prob enoth many thanks

droftarts

@mobietec generally you home all axes, which probes be centre, then probe as near as you can to each leadscrew, one probe per leadscrew.

Ian

Mobietec

@droftarts thank you ian so once is enoth i know when i did it in marlin it did it a few times till it was spot on

new error message now regarding mesh error invlaid higt map
my bed is 330 x 330

i have set center to 0

M557 X-135:135 Y-135:135 P5 is what i have at present

Mobietec

@mobietec fixed that updated the web and that fixed that problem many thanks

Mobietec

@mobietec where can i see the log reports please if this has any after the dual z i get bad command in config file any idears

@mobietec This is my bed levelling macro:

; Two point bed levelling, automatic leadscrew adjustment

M561                                 ; clear any bed transform
G29 S2                               ; disable compensation
G28                                  ; home all axes
M671 X255:-255 Y0:0 S5               ; leadscrews at right (255,0) and left (-255,0)
G30 P0 X135 Y-145 Z-99999            ; probe near right front adjusting screw
G30 P1 X-145 Y-145 Z-99999 S2        ; probe near left front adjusting screw and report adjustments needed
G1 X0 Y0 F6000

I also have a macro for manually levelling the bed; I have just three of the adjustable screws, not all six:

; Three point bed levelling

M561                                 ; clear any bed transform
G29 S2                               ; disable compensation
G28                                  ; home all axes
M671 X160:-160:0 Y-160:-160:160 P0.5 ; adjusting screws at front right (160,-160) and front left (-160,-160), rear centre (0,160) thread pitch M3 0.5mm
G30 P0 X135 Y-145 Z-99999            ; probe near an adjusting screw
G30 P1 X-145 Y-145 Z-99999           ; probe near an adjusting screw
G30 P2 X0 Y145 Z-99999 S3            ; probe near an adjusting screw and report adjustments needed
G1 X0 Y0 F6000

These rely on a number of settings in config.g, particularly M208 bed size and G31 probe X Y offset:

; Dual Z
M584 X0 Y1 Z2:3 E4                                 ; Set drive mapping - 2 Z right, 3 Z left
...
; Axis Limits
M208 X-165 Y-165 Z0 S1                         ; set axis minima
M208 X165 Y165 Z400 S0                         ; set axis maxima
...
; Z-Probe
M950 S0 C"exp.heater3"                         ; create servo pin 0 for BLTouch
M558 P9 C"^zprobe.in" H5 F120 T6000            ; set Z probe type to bltouch and the dive height + speeds
M558 A10 S0.003 B0 R0.2                        ; BLTouch extra settings from Phaedrux
G31 P500 X-30 Y0 Z1.65                            ; set Z probe trigger value, offset and trigger height
M557 X-145:135 Y-145:145 P5                   ; define mesh grid

Hope that helps.

In config.g? Send M98 P"config.g" to run config.g, and it will report errors in the console. Post config.g and error reported if you can't find it.

@droftarts uploaded your did a twick all working well many thanks no errors upon running many thank and i do aprecate the help

im slowley getting the hang of this lol @ me i chouice duet3 as i was told its the best

im trying out the config forst on the tronxy x5sa upgrading it soon to 3z then im going to rebuild it at 500x500 would like to do 4z but 1 step at a time next will be tool board this will free up a driver for me to do 3 or 4z

@mobietec nop run it again and again another problem its somthing i have done im sure of it left n right z screw

upon running code looking good untill it ajusts its self it ajusts left screw up and then the bed is out of wack grr not level

Mobietec

@mobietec off to bed will try again tommrow thanks all if you post any help ill pick it up in morning

@mobietec said in noob help dule z setup:

M671 X165:-165 Y0:0 S5 ; leadscrews at right (255,0) and left (-255,0)

This is a bit wrong. I define my Z motors in M584 first right, then left, and the M671 should be in the same order. You define yours left then right in M584, so you need to change the order of M671. Also it should be the position of the leadscrew, not the edge of the bed; my leadscrews are 90mm from the bed edge in X, so 165+90=255. Finally, you need to probe near the left leadscrew first, so swap the positions of the probe commands around, making sure the last command ends in S2.

Alternatively you can swap the Z motor connections on the Duet!

@droftarts thank you that part working now

But new problem my E0nnot extruding i plug in a seprat drive i can see its trying and feel it but no turning

Mobietec

@mobietec my current config e0 seems not to have enoth current flowing into it thats what it feels like

setup
drive 0 =X
Drive 1=y
drive 2=z1
drive 3=e0
drive 4=z2
drive 5= not conected yet

You've got M584 listed 3 times in there. It needs to be early in the config right after the M569 commands is fine. Delete the others. And make sure the one you leave is accurately mapping your drivers.
