I wish you good luck, I wouldn't dream of trying to print anything at 120mm/s but, then again, my priority is quality rather than speed.

@theBohnanza:

Hi, well that was a quick reply! Thank you.
Justine, you're right, the pick and place automation is the hardest part, but it has been done before.

Thank you.
Greetings,

Nice being mentioned!
Curious to see your results.

Pretty sure it was a wiring mistake on my part, but that is what I feared, will get another board and be more careful with it this time, thank you for the reaponce

BTW, Sorry if making threads of non-duet related stuff is not allowed. But the knowledge in this forum is superb.
Maybe add a general hangout discussion area?

Long story, short version:

Adrian Bowyer and I were working on an idea for a better electronics. Originally we were considering different processor options but then Arduino released the "Due" and at the time it felt important to work with the Arduino IDE so we went with the same MCU as the Due. After more development the Duet 0.6 was released.

During Z homing, the movement of the Z probe is limited to 1.1x the axis length. It has to be this big in case you home from max Z. So there is a "timeout" as you put it.

My guess is that you have a dodgy crimp connection in the wiring to the probe, or a faulty probe.

Lin Engineering also has torque/RPM curves at given voltages and the graph lets you estimate torque at a given RPM. The biggest lesson seemed to be to use parallel wound motors, which I think is where the maxim to use "low inductance" motors comes from, in a roundabout way. The graphs also show that higher voltage (within reason) is better than lower for getting a broader torque curve and faster RPM. This is why 24V is preferred for better, higher performance 3d printers.

At one time I wanted to make a dynamometer to help chart these things for different stepper motors, but I had other goals, and even 3dp machine designers don't seem to care much.

So disconnect the hot end heater from the terminal block on the Duet, set your multimeter to read ohms, and use it to measure the resistance between the two wires.

@vbtalent:

…
Assuming a 305x305x305 machine should it be the following is order important?

M208 X305 Y305 Z305 S1 ; Set axis maxima M208 X0 Y0 Z0 S1 ; Set axis minima

I then can remove the G92 commands from all the home'ing config's?

VB,

OK, thanks… S0 is for maxima and S1 is for minima in which case order is irrelevant.

M208 X305 Y305 Z305 S0 ; Set axis maxima M208 X0 Y0 Z0 S1 ; Set axis minima

If you connect with a second device, or if you pull the printer status with curl, be sure to go to this url to resolve this problem: http://192.168.0.192/rr_disconnect
I had the same problem, I was pulling the status with curl to display it in my statusbar, and adding a call to http://192.168.0.192/rr_disconnect after getting the json data resolved it.

dc42You're a Star after days of headbanging, Its finally working, Thank you.

Great, thanks. I'll take a look after I've printed a carrier to bolt the titan to the top of the belt carrage!

Getting challenged by these strings and with TPU I think the pressure advance/retract is only compressing or decompressing the filament in the bowden.

Nevermind, the problem went away after I connected power and ground to the Duex5.

Idiot!

That means you have an M1001 command somewhere, like in a g-code file, config.g, a macro, etc.

What were you doing before that?

Perfect, that makes sense. Thanks!

THX David.

Even renaming the old www folder to www_old and copying a "new" 1.19.3 WC did not help.

Then i upgraded to 1.20RC3 and noticed that DWC did not upgrade to 1.20 even though the files were correctly uploaded.
I completly deleted the old www folders (www and www_old) and created a new one with the 1.20RC3 contents… now it works.
Thumbs UP

I am still trying to figure out why the SD-card contents was not recocgnized correctly though….

I've not quite got it to print yet, I hit the stop after about 20 seconds, but with your settings MarMed I didn't notice any violent lurching like before. So within any luck… That's that sorted.

Did notice something now that grinding is gone, there is another grinding from the extruder stepper. The stepper can't seem overcome the pressure holding the fillament in place from the feeding mechanism without having an external force assist it from above. So... I probably have that a little too tight.... So the extruder issue was mechanical after all. (my extruder mechanism is new to me, I bought a Flexion kit along side the Duet. Probably should have taken one thing at a time.)
