@rabbit yes that should work, but don't try to do send a print file through USB because the Pi won't know that you are doing a print from file. And be careful of ground loops.

If you skip directly to 3.4 via Bossa, make sure you also manually update the DWC files in the WWW folder on the SD card. This may explain why you can't reach the web page.

@bernardomattiucci I'd think sharing 5V and GND shouldn't be a problem, but check the current draw of 12x optical sensors (plus the filament sensors) is not higher than the connector specification (3A for KK, I think), or the limits of the 5V regulator. See https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/Duet_2_WiFi_Ethernet_Hardware_Overview#operating-limits and https://docs.duet3d.com/Duet3D_hardware/Duet_2_family/DueX2_and_DueX5#operating-limits

Duet 2 5V current limit - 2.0A total on 5V and 3.3v, including the internal current consumption (around 200-300mA), any PanelDue or other display, and any endstops/Z probes that draw significant power.
DueX 5V current limit - (supplied by connected Duet 2) 1A total on PWM pins and fans (when internal 5V is selected)

Or use external 5V power supply on DueX.

@bast Looking at the external driver datasheet https://www.omc-stepperonline.com/download/CL57T_V4.0.pdf, your M569 timings for the external drivers seem okay. Do you have the enable wires connected? It says it has a 300 millisecond enable time. It could be, if you have the enable connected, that the drives are not having long enough to enable before the steps are sent. The datasheet says:

ENA must be ahead of DIR by at least 200ms [says 300ms on diagram]. Usually, ENA+ and ENA- are NC (not connected).

With ENA+ and ENA- not connected, the drives are enabled all the time, as soon as they have power.

Instantaneous speed (M566 Z30), max speed (M203 Z300), acceleration (M201) seem reasonable for the steps per mm (M92 Z320). What are the motors driving, belts or ballscrews? Is the bed particularly heavy? Are you using a motor brake (I can't see it configured in the config.g)? If it is linked to the enable signal on the external driver, perhaps it is not releasing quickly enough.

@martin7404 Thank you Martin! With these values I can get it to heat up until 70C without any errors. I still wish there would be a better solution like a "dumb" heater but at least I can work with it now 🙂

@dc cartesian is also the default kinematics, no M669 needed.

@oliof

That solved it thanks

@dc42 Hi,
I had a typo in my config. now it works fine.
Thanks for the great support.

@phaedrux said in Toolboard V1.2 faulty:

Can you remove the SD card from the Duet and power up the printer. Does the hotend immediately start to heat up when power is applied? If so, it would appear the mosfet has failed closed circuit.

If so, please send an email to warranty@duet3d.com and CC your reseller. Include a link to this forum thread and the details of your original purchase. You'll receive a reply with a form to fill out.

Sorry for the inconvenience.

Good morning,

Yes it does heat up. You already got email on this issue.

Cheers
Bengt

@phaedrux - hard to say if its been 14 or 24 months - i'll have to check my filatruder and other online resellers online accounts order history .. i have a few. Slapped a 1.2v in and it does NOT have the issue.

Ref;ashing its fw right now - fingers crossed

@leckietech do you have enough conductors to put a ground on each side of the PT100/PT1000 wiring? It will help hugely on the noise floor.

@paolozampini1973 as this is a new issue, use your new thread. I have undeleted it.

Additional feature request = Vin tap connector to get fixed voltage output for use for suitable gadget 😉

@dhusolo and a M955 P0 C"io3.out+io3.in"

Did anyone made progress on connecting all together?

@arnold_r_clark said in Need some help using inductive sensors as endstops:

I have them on a Duet Mini-5+ not sure if the Duet-2 would be any different

IIRC, the Duet Mini5+ input has high voltage tolerance. Not sure about the Duet2 hence the diode.

(If you rely on high voltage tolerance, please check yourself, don't take my post here as a fact).

@toma93

First thing I would do is check the wiring for connections that may be intermittent.

@jv the MB6XD specifications are at https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6XD_Hardware_Overview. It has three 5A heater outputs @ VIN voltage, six 2A outputs @ either VIN or 12V, and nine low voltage I/O ports. So similar to the MB6HC but without the bed heater output.

The tool boards or EXP3HC that you would need to drive your extruders also have I/O.

as soon as you do it right, it works 😉
