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

@jay_s_uk It is working, thanks!

@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

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

; Custom buttons
M950 J1 C"^io2.in"      ; define logical input for E1 filamentsensor
M581 P1 T2 S0 R2        ; define trigger for filament auto load (trigger2.g)
M581 P1 T4 S1 R1        ; define trigger for filament runout (trigger4.g)

Thank you very much both!

@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

@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

Hi all,

we are trying to test the reliability of our new loadcell probing system to see if it lasts 10 years.

it equals to a load of probes (213.000) which I plan to test in 4 stages (53.250 per test)

I wanted to test it with a loop;

while iterations<53250
    G30 P{iterations} Z-9999
;endif
G30 P53250 Z-9999 S-1

But quite quickly I get the error "Error: G30: Z probe point index out of range"

Is there a different way to do these long tests?

@droftarts Hi,

Get it, so I can only connect a digital sensor to the expansion boards??

May I ask why this limitation is in place? and is there a way to hack myself around it in firmware? Like can I trick the firmware into thinking there is a SZP connected? that seems to put out analog signal as well.

@droftarts

Thanks for the quick reply.

The loadcell circuit is now implemented to a custom Devboard we made, and therefore hardwired to a "Thermistor input". (based of of this previous topic; https://forum.duet3d.com/post/262561) We will see if we can rewire it to an IO input.

Can we then configure the P1 analog sensor from an expansion board??

As for the files; sure, we got a lot of help from the community so it would be nice to give something back. I cannot give the schematic tho, since that is still in development.
Basically, we self-developed the wheatstone-bridge load cell sensor with the 4-wire pinout (EXC+, EXC-, Sig- and Sig+). Then we wired these to an INA818 op-amp to amplify the signal significantly and used some diodes to limit the output voltage to 80mV and 1.92V to protect the ADC input on the chip. Amplification is set with a resistor

@droftarts @cosmowave

Tapping into this conversation; We made a loadcell amplifier board with the INA818 op-amp to boost the loadcell signal and we got a range of 80mV to 2.3V output, which we now wired to the temp2 input of our roto toolboard.

It successfully works when we configure it as a linear-analog sensor with M308, after which it shows as a temperature readout.

is there a way to convert this software-wise to a probing input?? I cannot figure out how to set P1 or P3 type from a thermistor input pin

@droftarts yeahh it is a big printer, belts are hanging free for 700mm, I need to tighten them a shitload to fix it, could this be the issue?

@droftarts to aid troubleshooting, I made 4 videos of short moves (20mm) at 200mm/s, at 10.000mm/s^2;

Only X-motor (Pure X-move);
Pure X.mp4

Only Y-motors (Diagonal move to front-middle);
Diagonal.mp4

Both X and Y middle of bed (Pure Y move);
Pure Y middle.mp4

Both X and Y all the way at left of bed (Pure Y move);
Pure Y left.mp4

You can see that the printhead only wobbles side-to-side on movement including both motors, and it is the same on the exact middle and all-left on the X axis

Thanks @droftarts!

Here you go, if you need anything else, please let me know!

@o_lampe It is the same everywhere.

Also happens on slow prints..

Moves with only X or only Y motors (left to rigt, or diagonal) are fine, so it only happens when a move requires both motors
