@Fatalis22
I recently switched to a BLTouch as well. My first thought is that when activating S2 (define Z to use probe), the Zstop is not activated.
I take that you also have your deploy and retract macros that you have uploaded to your Duet?
You could use the pinheaders on the connection hub for the EBOB. There are multiple PWM pins that you can use to use an extra endstop.
also, what is the J1 doing in your M581 command?
@Tpmoses You take the amperage value of the heater when they are all in series. When you use series-parallel, that would make it 20A right? Not 10. Still the heater has to be able to work at 60V. I don't know if you have an isolated heater but I got electrocuted once by my aluminium heated bed so make sure you have it grounded.
I have a 10mm aluminium plate which takes up to 30 min to reach 50 degrees.
@o_lampe If he says so, 5200W is a lot of heating power.
@Tpmoses Why above 5000mm2? It is just a matter of the amount of power that you put combined with the thermal energy consumption of your material. I have my heaters set so I can decide if I want both heaters or just one. Waste of energy to power them both if I only use half the area.
I would take into account that you have 4x1300W of power. Do you have a heavy duty power group? Normally the fuse would snap with this wattage.
I use two silicone mats that are put in parallel which give 530W each.
If you have a 1m2 bed with 5200W of power, that is more than enough. I have a bed of 1.4m2 with 1060W which gets my bed up to 50 degrees.
I would suggest doing it in parallel as that does not change the voltage of your flow for each heater. If one of your heaters fail and it is in series, they all stop. Also I don't know if your heater can work on 30V (120/4) when placed in series?
@droftarts That would be a big help for anybody who has the EBOB!
I use Leadshine D808 stepper drivers and I had a problem of the pulselength of my signals. They required to be a minimum of 5.0 us. Right now you have M569 P* T2.5:2.5:5:5, you could try that. It also recommends that in the manual of your stepper driver: https://www.damencnc.com/userdata/file/1750-1_DM556_datasheet.pdf
When using external stepper drivers, the M305 does not do anything since you use the dipswitches on your driver.
what is your wiring setup, do you have power-sourcing or sinking? I have all my + pins (EN+, DIR+, PUL+) powered on 5V, where I use the - pins for pulses.
Did you check the fuses on your board?
I would really like to see a picture of your printer if possible! I have one of X900 Y1400 Z400 and thought that was already massive!
I also use the expansion breakout board and that gives me 3.3V but using the 5V setup as previously explained, I can change the difference in voltage which makes a switch.
Thank you! That did the trick
(such a simple answer can be so frustrating haha)
Re: using BLtouch when using Duet Breakout Expansion Board
As can be read in the topic above, I want to use a BLTouch for my printer.
I use a Duet wifi + Breakout expansion board.
Of all the expansion boards and manuals, this particular board has no manual on the wiki unfortunately.
M115: FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-05-19b2
DWC 2.0.7
What I did:
I used this website (https://duet3d.dozuki.com/Wiki/Connecting_a_Z_probe) to set my BLTouch.
Since I do not have a Duex I used this setup. Because I use the Expansion Breakout board (EBOB), the pins in this table are not available.
I used the H7_PWM on the EBOB where:
Heater3 becomes exp.heater7
+5V is +5V (on H7_PWM)
GND is GND (on H7_PWM)
Z probe in and GND are for the white and black cable.
Don't mind the colors of the cables, they are correct. I double checked all the cables
When I start the printer, the BLTouch does deploy and retract two times. From that, I conclude that the cables are correct.
My problem is with the software implementation. I followed all the instructions on every page I could find, tried the troubleshooter but it does not react to my commands.

I also have a deployprobe.g:

and a retractprobe.g:

I tried with and without the I1, no difference.
I tried different values for P as long as they corresponded with the P/S from my M950 command (as it suggests on the manual pages), no difference.
My M401 and M402 don't do anything.
I read that the M307 H7 A-1 C-1 D-1 does not do anything but I tried it with and without, no difference.
I also read that you should check your config-override.g but apparantly I do not have one.
I think something is wrong in my code but I can't figure out why. I followed the instructions of @Phaedrux in the previous topic but somewhere I must have missed something.
I hope that somebody can help me.
Thanks in advance.
@Phaedrux Thanks, can I use my heater6 or heater7 pins for my BLtouch endstop?
@Phaedrux Can I use those for an end stop and/or an emergency button? If so, how do I put this in my config code correctly?
Hello,
I have a Duet Wifi (3.1.1) where I added a expansion breakout board for external stepper drivers.
I have reached the limitation of missing pins multiple times right now:
I already have the expansion breakout board and need it for my external stepper drivers. Since the board uses a 50 pin cable, the pins within are not useable anymore.
Is there a way to combine the expansion breakout board and still have these options?
Thanks in advance
@bearer what do you mean by that exactly? It is a free endstop (I am not using multiple extruders so E1 is empty).
This is the diagram for the fault signals:
Looks like 5V. I am not an electrician but I thought of using this signal in a relais, that links the 5V of the endstop to the Endstop input, leaving the ground untouched. Is that a workable option?
@bearer it was 24v so I disconnected it.
I want to use this signal so I thought of adding a relais that activates the endstop. Should I put the ground somewhere and direct the 5V signal to the endstop. Should that work with the current M581 code?
Hello,
I use external stepper drivers that contain fault pins with an optocoupler that put a signal to the Duet board when in fault. Right now I put this signal (that gives a positive signal) to the e1 endstop.

I am wondering a few things:
Thanks in advance.
as requested:
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...
Strange things happen,
When I raise my maximum speed and acceleration, my speed on the printer does not go up. I changed it from 6000mm/min to 9000, no difference. Any clues why that could happen?
sending it soon, as you see I first have to clean my extruder head haha
@T3P3Tony Thanks for your answer
The thing with the 1600/rev is that my duet says that I have a x16 microstepping but my stepper driver is set at x8. This does not give me a wrong movement so I just found out just now. Can I leave it like this? You say that M350 has no influence but the Duet gives the amount of pulses right? So x16 has twice the pulses compared to x8.
The strange thing is that this does not happen at extreme speeds but randomly. I printed multiple parts with a higher speed and when I try to move my exttuder at max speed (100mm/s), I never get an error. The error occurs after some time.
The big problem here is that there is no feedback from my printer. The printer does not know the motor is in fault. That is why the extruder also keeps going.
Somebody told me that this could also be caused by the following:
M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min)
That the instantaneous speed difference is too big. This could be the problem, but I am not sure. I have a picture added to see what happens if the motor stops working!
I know the quality of the printer is not optimal here, but I use a 0.8mm nozzle with a printbed over a 1m2 so it is not designed for small shapes.
I had this error also when printing something of 40x60cm
If anybody could maybe help me with the M566 line and if that could be of any influence, thanks a lot!
Thanks for your elaborate answer,
The results of M115 are:
IRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 3.1.1 ELECTRONICS: Duet WiFi 1.02 or later FIRMWARE_DATE: 2020-05-19b2
I checked your config suggestions and I found something that I am not sure about. According to my own settings, I have a x16 microstepping and a 80steps/mm.
When I check my stepper driver dip switches I find a 1600/rev resolution, which would need a x8 microstepping.
Could it be possible that my microstepping should be x8, while my movements are correct at the moment? (100mm command results in a 100mm movement). I find this hard to be true but could be the problem.
The Duet then gives too much steps compared with my settings.
I use a 20mm/rev spindle as axis.
My plan:
Change the code to x8 microstepping and try everything again
My fear: movements are not correct afterwards anymore
Many thanks in advance.
Hello,
I've asked some questions about this already but everytime something else comes up.
I use external stepper drivers to support my NEMA34 motors.
I had some problems with the pulse-width resulting in a 'position following error'. (I use ES-D808 stepper drivers). I asked that on this forum where people stated that I needed to extend my pulse width to a minimum of 2.5 microseconds (that's what is recommended as minimum in the manual)
After setting that up, I used the following config code (for this part):
; Drives
M569 P5 R1 S1 T5.0:5.0:5:5 ; physical drive 0 goes forwards
M569 P6 R1 S1 T5.0:5.0:5:5 ; physical drive 1 goes forwards
M569 P7 R1 S0 T5.0:5.0:5:5 ; physical drive 2 goes forwards
M569 P8 R1 S1 T5.0:5.0:5:5 ; physical drive 3 goes forwards
M584 X5 Y6 Z7 E3 ; set drive mapping
M350 E16 I0 ; configure microstepping without interpolation
M350 X16 Y16 Z16 I1 ; configure microstepping with interpolation
M92 X80.00 Y80.00 Z320.00 E410 ; set steps per mm
M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min)
M203 X6000.00 Y6000.00 Z180.00 E1200.00 ; set maximum speeds (mm/min)
M201 X500.00 Y500.00 Z20.00 E200.00 ; set accelerations (mm/s^2)
M906 X800 Y800 Z800 E800 I30 ; set motor currents (mA) and motor idle factor in per cent
M84 S30 ; Set idle timeout
When I am printing, the first 5 hours go well and after that, one of my stepper drivers get a 'positioning following error' and stops moving. I have set all my motors in serie so they all stop moving (I have a parallel x-axis so it would rip the printer apart if I don't do this).
This is the main problem, but it causes another: The printer does not know my stepper driver goes into fault. All my axis motors stop but the extruder does not. You can guess what that problem becomes, my extruder creates a big blob.
I now have the plan to connect the fault-signal from my stepper driver to the reset pin of my duet board. This is not the optimal solution but prevents my printer from breaking itself down. If there is a stop function without end-stops, I am more than interested to learn about this!
My big question: How is it possible that my stepper driver goes into fault after 5-6 hours of printing? My pulse width is long enough (>2.5 microseconds) so should not be the problem. Anybody who recognizes this problem?
Many thanks in advance!
Hello,
I use ES-D808 stepper drivers (closed loop) and I found the M569.1 function. When I want to use that, do I also need the M569?
M569 P5 R1 S1 T5.0:5.0:5:5 ; physical drive 0 goes forwards
M569 P6 R1 S1 T5.0:5.0:5:5 ; physical drive 1 goes forwards
M569 P7 R1 S0 T5.0:5.0:5:5 ; physical drive 2 goes forwards
M569.1....?
I use a duet 2 wifi with the expansion breakout board.
thanks in advance
