CR10 S5 upgrade to Duet 2 Wifi

GT1Za

Hi Everyone,
Im hoping I can get a bit of assistance. This is the first time Im trying to do something like this, and the first time Im trying to learn anything to do with Gcode.
Im upgrading my CR10 S5 to the following:
3D Fused Linear rails - this should make no difference.
Keenovo AC heatbed with SSR - again with the SSR it shouldnt make any difference
Hemera direct drive
BL Touch 3.1
(If someone has done this and would be happy to share their config and firmware files with me, Id appreciate it)

Below please see my wiring, I think I have it done correctly, but though it was worth posting in case I hadnt.

One this that I did change, I had the Extruder plugged into E1, I have moved this to E0.

Things that seem to be working:
X, Y, Z motors are driving. However I dont think Z is setup correct. If someone can confirm settings for the S5?
The steppers are all the standard ones that came with the machine.

Extruder (Hemera)
Heats up fine / Cools down fine
Fans switch on once temp is about 45 degrees.
Forwards/Backwards works but esteps seem completely out - would appreciate assistance in getting this right?

BL Touch wiring is as follows:
White and black to the probe in's on the board.
Brown wire to GPIO 1
Red wire to GPIO 2
Blue wire to GPIO 8

When I power on, the BLtouch does its normal start up check by dropping the pin twice. So I believe the wiring is correct.

When I try run G29 i get the following error:

Absolutely lost with what to do here?

Thanks for the assist

Sounds like you're missing the definition of the bed mesh in config.g. This is from my CR-10S, so it'll need adjusting for you:

M557 X35:265 Y35:265 S46		; Define a 5x5 mesh grid

https://duet3d.dozuki.com/Wiki/Gcode#Section_M557_Set_Z_probe_point_or_define_probing_grid

You may also want to post your full config.g for further help

@GT1Za
I think your problem is your mesh definition is too aggressive. You're probing 480x480mm at 20mm increments, that's 576 points which I think is above the limit. Try changing your M557 line to this:

M557 X15:495 Y15:495 S40 ; define mesh grid

That's 144 points over the bed, 40mm spaced. See if it works then

GT1Za

@NexxCat that worked, I took it up to S80 for a 6x6 mesh. Ill experiment later to find the right values.

Now the if I run the Auto Bed Compensation, its starts, but the BL touch probe doesnt deploy?

NexxCat

@GT1Za
Do you have deployprobe.g and retractprobe.g files? If so, what are the contents of each?

GT1Za

@NexxCat

; deployprobe.g
; called to deploy a physical Z probe
M280 P64 S10 ; deploy BLTouch

; retractprobe.g
; called to retract a physical Z probe
M280 P64 S90 ; retract BLTouch

NexxCat

@GT1Za
In config.g, change:

M307 H64 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch

to

M307 H3 A-1 C-1 D-1 ; disable heater on PWM channel for BLTouch

and in both deployprobe.g and retractprobe.g, change the P64 to P3. Then try

GT1Za

Nope.. Still says Z probe was not triggered during move.

NexxCat

@GT1Za
Does it deploy now though? From the photos it looks to be wired into pin 8 of the expansion connector, which is Heater 3. Your config had it looking on Heater 64, hence the change.

NexxCat

@GT1Za
Just noticed something else also. You have the original Z endstop plugged in and configured. I don't as the BLTouch does all Z homing. Try the following changes in config.g:

M574 X1 Y1 Z1 S1 ; set active high endstops

to

M574 X1 Y1 S1 ; set active high endstops

Add:

M574 Z1 S2                              ; Set Z endstop controlled by probe

GT1Za

@NexxCat

Ill try it now. Ive always liked the idea of keeping the z stop incase the BLtouch fails. Is there no way to keep both?

NexxCat

@GT1Za
I have no experience with that I'm afraid, so I can't help, but people here are really friendly and knowledgeable, so someone else may know

GT1Za

ok, Z probe still didnt deploy when trying to home the Z. I had to hit the stop button.

NexxCat

@GT1Za
Just to double check. The brown wire from the BLTouch is definitely plugged into Pin 8 of the expansion connector?

GT1Za

definitely into pin 8

NexxCat

@GT1Za
DOH! I know what I missed.

In both deployprobe.g and retractprobe.g, add I1 to the end of the parameters:

deployprobe.g
M280 P3 S10 I1

retractprobe.g
M280 P3 S90 I1

GT1Za

@NexxCat
I have just checked the wiring diagram:
Pin 1: To Red
Pin 2: To Blue/Brown
Pin 8: To Orange/Yellow

This is as per: https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe

This is how I have it wired

I have added the I1 to both, but still not deploying

NB: This is not deploying on HOMING the Z as I cant run the mesh bed before homing.

NexxCat

@GT1Za
Hmm, and you still have the config.g M307 set to H3?

Looks like the BLTouch isn't receiving the servo signal. The "I" parameter in the deploy and retract is needed because we're wired directly into the expansion connector, if you had a Duex, it wouldn't be required, but with the correct heater configured (heater 3), and the inversion, it should work $:\$

Edit: Can you post your homez.g and homeall.g please?

GT1Za

in the config.g:
