@T3P3Tony while saying script, I mean gcode marcro.

Test fire or with the other name sending pulse is used while adjusting the mirror alignments. With sending test fire, you are checking are you hitting dead centre on 1st mirror, 2nd mirror and 3rd mirror. And as a last step, to test nozzle exit - for detecting are you hitting any side walls of nozzle or not.

Hi, on my old 80w laser, test button on power supply not working any more. Probably due to having an old 80w tube.

I have written a sample script to handle test fire, it is moving the nozzle 1 mm away and meanwhile test fire is being shot.

But I wonder, is there any way to simulate test fire without moving the nozzle. Because if laser beam hitting the nozzle with my script you can not identify.

Thank you

Thank you so much for both

Hi,

I have bought Roto Toolboard and trying to make connection with stepper motor.

But the connection on https://docs.duet3d.com/duet_boards/duet_3_can_expansion/duet_3_rrtb/duet3_rrtb_v1.0_wiring_latest.png is not clear. Are A+ and B+ placed to upper row or lower row?

Additionally, I can not reply to the questions which I have asked, is there any limitation?

Thank you

Hi,

I was thinking that I can connect existing pre-crimp wire to toolboard.

Or at least provided cable can have connector pre-crimp.

Or at least they can provide a connector to crimp.

But as I receive it today. There is only one cable without any connector. And now, I need to buy a connector and crimp tool for one time usage only.

Could you suggest which one I need to buy from Amazon? Otherwise I need to return the product to seller. It will be so much cost to go forward.

Thank you

Hi,

I am planning to buy Duet 3 Roto Toolboard. Documentation states that it includes integrated LDC1612 inductive sensor for scanning Z probe. In this situation buying scanning Z probe coil is sufficient.

Where can I buy coil of scanning Z probe?

https://www.duet3d.com/Duet3ScanningZProbe section is selling with pcb and I do not need it.

Thank you

Hi, recently near the end of printing, print had stopped with VIN under-voltage event.

But interestingly, printer has connected to uninterrupted power supply.

What may be the cause of this problem?

I am using enclosed Voron 2.4

Thank you

Hi,

I have build newly a Voron 2.4. But I am repeatedly meeting with heat creep issue in direct drive system. Fan is blowing more than enough to cool.

My configuration was using interpolation for all stepper motors. But I have read that turning of interpolation for extruder could eliminate the issue. What do you think? If interpolation needs to be turned off, what do you suggest as value (x64, etc...)

Hotend is standard E3D V6. As a last step, if I can not resolve I will change hotend as well.

Hi, I want to buy an accelerometer for Voron & V6 hotend & Afterburner & Duet 6HC v1.01a.

Which one do you suggest? Actually all are seem a bit similar to each other, but I am worrying about how I will mount it to the afterburner.

I can directly mount accelerometer to Duet 6HC v1.01a, isn't it?

Thank you

Hi,

I have Duet 3 3HC and Duet 3 MB6HC. Interestingly, after updating the firmware on both devices, CAN-FD BUS for connection to the Duet 3 Mainboard is starting to communicate after 30-40 minutes, sometimes I can not achieve any connection.

Board: Duet 3 MB6HC (MB6HC)
Firmware: RepRapFirmware for Duet 3 MB6HC 3.4.6 (2023-07-21)

Is there a way to speed up this process?

Thank you
