Setting up DUET wifi + Duex5 - help needed
-
I also have PT100 sensors reading 2000 degrees but again, little steps)
PT100 seems to not be getting a response… check wiring?
-
Thasnk for the help. I will double check the wiring on the PT100's this evening. I also have a bed thermistor reading 120 degrees when it is about 10 though? Is there a common between all of them that I perhaps have not set?

Regarding the PT100, the X parameter in M305 P1 should be 200 for the first PT100. X100 is for a thermocouple.
Regarding the bed temperature, what bed thermistor are you using?
-
100k thermistor i think.
How can i check the deux is getting power? it reports that it is there when i send the m115 command. thanks
-
Run M122 and see what status it reports for the stepper drivers on the DueX.
If you have a multimeter, I suggest you measure the resistance of your bed thermistor at room temperature, to check whether it really is a 100K thermistor.
-
OK, I had an issue with uploading the zip file and it was seemingly corrupting, hence nothing worked! I am using the editor in the web interface and have got axis movement
However I still have issues with the temps. The bed temp seems to read 124.8 (it wobbles a bit) when the temp should read say 10, and the PT100 still reads 2000. I have attched the ( I think) relevant bit of code; Heaters

1. Measure the bed thermistor resistance with a multimeter. Perhaps it isn't a 100k thermistor.
For the PT100:
2. Send the M305 P1 X200 from the command line and see if you get an error message back.
3. Are you sure you have connected the PT100 to the first channel of the daughter board? If it is connected to the second channel, use X201 instead of X200 in the M305 command.
4. If you are using a 2 wire connection to the PT100, do you have the 2 jumpers fitted on the daughter board?
-
OK, I have two working temps now. I had a bad connection on the PT100 daughterboard as well as the bed thermistor, both now sorted and working
I have the IR bed level sensor from think3dprint3d. I was not sure of the sensor type on the config tool. What should this be? I dont want to crash the bed instantly!

M569 P7 S0 ; Drive 6 goes backwardsCan the U axis zero at the other end of the carriage (ie the X zero on the left and the U on the right)? I then presumably need to tell it the distance between the two to calibrate them together?
At the moment I am using hall effect sensors for the end stops which seem to work but I think I read somewhere that you can do away with the sensors and wait for missed steps from the drivers? Is this now working?
Cheers

1. Select "Unmodulated or smart IR sensor" and set the trigger value to 500. See the commissioning instructions at https://miscsolutions.wordpress.com/mini-height-sensor-board/. Test the Z probe before you rely on it.
2. You also need to declare the U endstop at the high end of the axis in M574, and the U axis limits in M208. Adjust the U upper limit to get the X and U nozzles to print at the same X position.
3. Homing using motor stalling isn't very precise. Often this doesn't matter, but on an IDEX machine you need the distance between the X and U homing positions to be highly reproducible. So I suggest you use endstop switches.

DC, many thanks for the help. I think I am getting there (slowly but steadily). It will be a bit of a long burm as I am sure I will keep tweaking!
Quick question. My z axis motors are rated at 2.1A per phase.
Do I therefore set M906 Z 2100 ? Just wanted to check before I blew them up!
Also, when I zero the y axis it is actually 25mm off the front of the build plate. (If I move y to +25 it is actually at '0' on the build plate) How can I set this up as to be the zero point? I also have the same issue on the x axis?

I am guessing that you have the Y endstop switch at the low end of the Y axis. In your M208 S1 command, change Y0 to Y-25. This command defines the lower axis limit, which is also the assumed position when a low-end endstop switch triggers during homing.
-
DC, yes, the y axis endstop is at the minimum - all working now
I have set the current to 1750 and seems to work. Although I think I have a loose connection as sometimes one of the motors stops and then the platform jams up! I will chase it though
Presumably to get the 'hardware' levelling using the z motors (https://www.duet3d.com/forum/thread.php?id=1203) I need to move the motors to be on independent motors drives rather than both on driver 2. I will have a crack tomorrow time permitting.
Cheers

Yet more (sorry) question. I have a fan in the DUET housing to blow cold air at it when/if it gets hot. This is connected to fan 7 on the DUEX5. Is there a method of applying hysteresis to control it?
on at 50degrees
off at 40 degrees -
If you put T40:50 in the M106 command, the firmware will try to control the fan with PWM between the range 40 and 50. So 39 will be off, 40 may start to turn slowly depending on how the fan reacts to PWM, 50 will be full on and 45 will be half on. This is how I have mine set and it works very well.
Edit. Otherwise with a fixed temperate eg. T40, there is 1 degree of hysteresis. That is to say, the fan will start at 40 but the temperature must drop to 39 before he fan turns off.
-
Not hysteresis, but you can set it to come on at e.g 30% at 40C rising to 100 at 50C:
M106 P# L30 H100 T40:50
where # is the fan number.

David,
Unless things have changed, H is the heater number is it not? Just that your example in above, conjunction with the wording might indicate that H100 is the maximum speed.
-
Yes H is the heater number. Heater 100 is the default virtual heater number for the CPU temperature.
-
Many thanks for the help. I have got most things working but have a mechanical issue on the z axis. I have redesigned and am printing (on a different print) the new parts and waiting for some others to arrive in the post! Cheers
-
Sorry for the long delay in getting back. Things always seem to take longer than hoped! However I now have the z axis working properly and the IR sensor triggering. I have a 3 z motor setup, so am hoping to do 'hardware' bed leveling as well as mesh leveling. However, I am running into a strange issue. Note, I have updated to firmware 1.21RC5, and when using the machine control tab all axis move correctly and homing of x and y works perfectly
When i call home z from the web interface the machine appears to randomly move and then all of a sudden it goes to a point that almost appears to be the probe point. During the random moves however it crashed the x axis into the hard stop and then the motor skips. I then get worried and turn it off before it breaks something!
I know it must be something i am doing but not sure what.
Any help greatly appreciated
thanks

If you upgraded from pre-1.19 firmware, delete any default deployprobe.g and retractprobe.g files that came on the SD card.
