@droftarts That would be a big help for anybody who has the EBOB!

Yes you could use the heater pins for the bltouch servo control, 5v, and ground connection. The trigger signal would still need to return to the mainboard.

should be fine to wire fault- to ground and fault+ to stp, even for multiple fault+ signals to the same stp pin.

edit: stp is the silkscreen label, the wiring diagram says e1stop, just to be clear.

edit2: by the looks of it you should use ^ in the config to enable internal pull up of the endstop pin name.

It is going to be changed a lot (bed is going to be reduced to 1000mm instead of 1400mm), maybe change the Gantry, way too heavy right now...

M569.1 pertains only to the Duet 3 closed loop expansion board that is under development.

the endstops do not stop my print from extruding. They only block further movement. Right now when my x axis goes into fault, the extruder keeps going while I want to abort the print. I thought just activate the reset pin on my expansion board. Why won't that work?

Thanks in advance

okay never mind. It works now, maybe it takes some time to work through the fuse.

It worked. New fuse of 7.5A made it work again. Takes a few minutes after setting up to provide enough current to hotend

@Veti said in Heatbed heating to slow:

try something like
M307 H0 A199.0 C962.6 D60 B0

I don't think you even have to specify the A and C values, just specify a large D value.

M307 H0 D300 B0

D is the deadtime between sending a heating command and getting a temperature increase. Based on what you know of the heater setup, how long do you think it should take to increase temp by 1.8c?

And then try to auto tune it with M303 H0 S60

If that still isn't enough, increase the D value more.

@Veti @jay_s_uk

Thank you so much! It worked! Finally worked out the problem I encountered weeks ago!
You have both made my day

kind regards,

Peter

Do you have specs for the inductive sensor itself? Is it NPN or PNP?

@peterartechno Sorry, my mistake, the breakout board signalling is a differential 3.6V signal, ie -3.6V to +3.6V. You can wire it for 0 to 5V signalling, see https://duet3d.dozuki.com/Wiki/Duet_Expansion_Breakout_Board#Section_Notes

You'll need external power to the D808. It takes 24-72VDC. If it will accept a low current 3.3V signal, you don't need the breakout board and can connect it direct to the relevant pins on the expansion pin header of the Duet. See https://duet3d.dozuki.com/Wiki/Using_external_stepper_motor_drivers

@peterartechno said in Using a Duet 2 board with external stepper drivers:

Is it also possible to connect the E+, D+ and S+ within the driver and using one cable to get to the 5v?

Yes, that too.
