@jay_s_uk Wow I seriously have read over that 10 times I think. sorry for the unnessecary question
Thanks all!

@Notepad works really well, thanks!

Got good results too, and plotted them in graphs! which shows a fun correlation of the temperature drift of our probe!

Thanks for the script! Appreciate it

Hi all,

We have made a 3D printer with 2 micro-Z printhead axes (V and W), which move the IDEX printheads up and down 14mm to level 2 different tool types and automatically adjust/calibrate the printhead Z-offset.

We first got this system working with a microswitch type probe, which we, in a macro, temporarily reconfigured as an endstop for axis V/W, which we then "homed" towards the printed until triggered. When done for both tools, this calibrated the Z-offset automatically.

Now, however, we moved over to a loadcell probe (analog readout via configuring as scanning Z-probe, amplified and filtered with custom CAN-communicated PCB) which we cannot configure as an endstop to home towards.

My question is;
Is it possible to do a G30 S-1 probe (just probe and stop) with a probe number defined (K0/K1), but move axis V or W instead of the Z-axis

note;
running 3.6.0 beta-2

@SanderLPFRG Got it working, version mismatch.

@chrishamm It works!!

It both updated correctly, and now the M291 functions correctly.
Massive thanks Chris and Tony.

I'll now work on trying to understand how I can use the input to trigger Gcode commands

@gloomyandy said in Trying to fix my dual markforged (HAQ-XY) kinematics:

at it is probably not a good thing

Ill redesign the belt tensioning mechanism and the belt mounting, when measuring it indeed looks to be too loose
WIll see what this does

@jay_s_uk It is working, thanks!

@OwenD I did exactly that yesterday late afternoon. It is working now.

@OwenD Damn, this did the trick. Thank you so much owen! also thanks @chrishamm

@Notepad @droftarts ,

My goal is to test a shitload of probes, and see how much it starts to deviate after thousands. Your script might actually work, let me test

@droftarts 3.6.0 beta 2 and beta 3 tried both

when printing with tool 2, I often get a "outside of machine limits" error at the first G2 movement of a Gcode, even if the moves are well within these limits. Below I attached my config, the first part of the failing code, and the console with error.

Testing I already did;

• The same code does print correctly with Tool 1.
• The same model (nothing else changed) does print when arc fitting is disabled

Could this be a bug?

Console;

@jay_s_uk yeahh I tried that already, but selective probing with scanning-type probe still tries to, youknow, scan.

Guess the only possibility is to enable the possibility to define a type1 probe on a CANboard

@jay_s_uk Hi, thanks for the reply
You mean setting the Probe type to P0? can I then still do a G30 probe with the load cell?

Hi,

I can now only configure our analogue-in loadcell probe as a SZP, which reads the signal correctly, and G30 functions well, but when doing a G29, it tries to scan the bed, resulting in a nozzle that scrapes the bed.

Until I figure out the firmware, I want to enable a simple mesh probe manually, which I want to do with;

M561                    ; clear any bed transform

; If the printer hasn't been homed, home it
if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed
  G28

; Probe the bed and do auto calibration
G1 X{move.axes[0].min} Y{move.axes[1].min}  U{move.axes[3].max} Z10 F12000   ; go to neutral position

;Start probing
G30 P0 X25 Y25 Z-99999
G30 P1 X299.5 Y25 Z-99999
G30 P2 X574 Y25 Z-99999
G30 P3 X25 Y250 Z-99999
G30 P4 X299.5 Y250 Z-99999
G30 P5 X574 Y250 Z-99999
G30 P6 X25 Y475 Z-99999
G30 P7 X299.5 Y475 Z-99999
G30 P8 X574 Y475 Z-99999
G29 S3 P"usual.csv" ; save probed points to "usual.csv"

I wonder if such thing is even possible, any tips?

@dc42 is it okay if I try to enable this functionality in a branch via github? If I manage I will make a pull request for you to integrate it into the main branches.

Lot to learn for myself, but I like a challenge.

@SanderLPFRG Got it working, version mismatch.

@dc42 I just tried to build with the latest master branch of the libtinyusb from here; https://github.com/Duet3D/LibTinyusb

I also tried the 3.6.0 beta2 release, which is the same as the rrf sourcecode I am trying to build

still did not work, same error

@dc42 please note that the tusb.h file is actually present

@dc42 said in Other analog Scanning Z Probes?:

Yeahh the biggest issue is that I do not want the loadcell configured as a scanning-type probe, but as a normal analog probe, which is prohibited for CANboards. so I am leaning to version 2.

I am trying to build new firmware for the 6HC (to remove the error it raises when remote Z probe type is not 8, 9 or 11) but I am getting building errors regarding the CoreN2G...

"../src/TinyUsbInterface.cpp:28:10: fatal error: tusb.h: No such file or directory"
