works perfectly after updating to the new firmware, thx.

thx

No problem, i was not able to mess with my printer last week at all. So can i roll back to the stable 1.19 and it will work?

so i removed the temp probe and set the config.g M305 to channel 150, or 151 it works fine. but as soon as i connect the temp probe and activate it by setting the correct channel the x axis moves fast and a lot farther than it should. say if i put the temp probe in channel 150 but set M305 to channel 151, the x axis works as it should. but as soon as i set M305 to the correct channel 150 the x axis does not work as expected. the only thing i have not changed is the duet thermocoupler daughter board. but before i put down a chunk of money on a new daughter board how can i be sure it is the board?

@dc42,

Ok, this is the setup: I have a E3D TYPE K THERMOCOUPLE (CARTRIDGE) connected to my thermocoupler daughter board on channel 150.

with the M305 X150 command with the thermocoupler wire connected, the x axis DOES NOT work as it should, BUT I do get a temp reading and it is correct. IF i keep everything the same and change the M305 to X151 the temp reading does not work (as it should, because not wire is not connected to channel 151) BUT the x axis works as expected.

So if i setback the M305 command to X150 and REMOVE the thermocoupler wire the x axis works as expected. so this tell me the thermocoupler wire is the culprit but only when that channel is selected. Does this mean the thermocoupler wire is bad??? But i get a verified temp reading.

I don't have a spare to test, but i just don't see how the wire would cause the x axis to work erratically.

suggestions???? I'm going to order another thermocoupler wire just in case. but it will be a week before i get it. so if you can think of any other things that might be causing the wire to make the x axis not function correctly i would appericate it.

I did try channel M305 X152 and 153 with the wire connected to channel 150 and the x axis did work correctly.

thx.

So, I am building an CoreXY printer with a build volume of 300x300x300 and I have the duet Wifi board running firmware version 1.20beta1, DuetwifiServer 1.20alpha1. I also have a Duet Thermocoupler daughter board , can't remember what version but it has the two default leds on it. The firmware has been install for over two weeks and I have not had any issues, except for configuring issues with thermocoupler and setting z probe. yesterday I got home and just turn on the printer and noticed that the printer x axis was moving fast. if i selected to move the x axis 1mm it zips across about 100mm (just a guess, never measured) moving very fast. I thought maybe the steps/mm setting was messed up but it wasn't. Its what is has been set at for a couple of weeks, 100. so I try adjusting the x axis down to 50 steps/mm to see what happens. it slows down but since i only adjusted the steps/mm for x axis only the x axis move, slower, and also it moves the y axis. I'm assuming this is happening because with the steps/mm set like this: M92 X50 Y100 it causing both axis to move due to different speeds. so I adjust both axis (x,y) to the same steps/mm (50), but now the x axis moves right but the y axis moves way lower than it should. where before if i wanted the y axis to move 1 mm it moved 1mm. but with adjusting steps to 50 it only moves about 0.5mm. so, that didn't work. so after some tinkering and changes in code this is what I have noticed:

1. the board led lights have changed;
   a) before the x axis strange behavior the Diag led was not on, now it is. From what i read the diag led isn't even used for anything. so I'm not sure whats going on here.
   b) the led light was on for each motor attached was on, where as now non of them are NOT on.
   c) these are the only led lights on on the board: Diag, 5v, 3.3v, VIN
2. with the following theromcoupler setting the x axis is not working correctly: M305 P1 T100000 B4138 C0 R4700 X150 IF I change the same M305 code to X100 (thermocoupler not working) the x axis moves correctly. NO other change made except for this.

To me this should have nothing to do with stepper motor movement. So i did a little more investigation, I removed the thermocoupler board and left the M305 code to X150 , not commented out, all axis worked correctly. I then re-installed the thermocoupler board and left the same M305 X150 code and the x axis was not working correctly. it was zipping across the axis. If i change the code to M305 X100, with thermocoupler board installed the x axis worked correctly.

I'm stumped. not sure why all of a sudden the x axis started working crazy. I have not tried adjusting the M350 X16 Y16 microstepping with interpolation. Not sure what that will do it each axis (x,y) having different settings will do. So, this is where I'm at, any suggestions or possible additional troubleshooting would be appreciated. here is all the config settings i have.

so switching the polarity worked. it now triggers with a light touch of the bed. But now my x axis move is all crewed up. I haven't changed the code except for turning on the power when i got home, now x axis is screaming across the axis. if i select a 1mm movement if move about 20mm VERY fast. I going to move this issue to the appropriate section. as for the probe i consider it fixed.

thx everyone.

@DjDemonD

I like this guide..thx but i do have a question. in this section:

M558 P1 I0(or I1) R0.4 F300 X0 Y0 Z0
(analogue mode, NO/NC, delay, speed, not used as axis endstop)

shouldn't it be Z1, as the probe is used as an endstop for z axes?

-curtis

DjDemonD, on another note, i did speed up the bed probe speed to your suggestion of 420 mm/min and it seem to help a little, but the bed is still pushing way to hard to trigger.

So DjDemonD is correct, when i tap lightly on the side it triggers But i did try pushing straight up on the hot end as the bed would do but it did not trigger right away. I did not notice (or wasn't paying attention) if it was triggering after a lot of upwards pressure or maybe triggering when i started to let off. either way I'm going to try and reverse polarity, as kazolar suggested, tonight and see what happens.
thx guys.

so i got the probe to trigger BUT it won't trigger unless the bed pushed hard on the hot end. i set the V2 sensetivity to just as the blue led turns off and i give it a VERY light tap and it triggers, by the blue led. But when i run the homez the hot end still pushed hard against the hot end till it triggers. if i tap the hot end on the bottom "lightly" it triggers. for some reason the slow motion rise of the bed is not triggering the piezo. Did i setup the piezo wrong? is it clamped too tight together (top and bottom) pieces?? I followed the directions in the video. any suggestions would be grateful.
thx in advance.

I took the setting you had posted on another forum thread that I found here: https://www.duet3d.com/forum/thread.php?id=752&p=3

DjDemonD, thx I will try it when i get home today. I did have it set to I0 prior but when it was not working I was changing all the settings trying to get it to stop the bed. So, Im going to set it back to I0 and with DC comment it now make sense why it was not working. So, i have a lot of stuff to change later. On another note I did read you stuff you had on Thingiverse it was helpful.

here it is:

In your code delete: ; M574 Z1 S0 ; Define active low and unused microswitches

and change this line: M574 X1 Z0 Y1 S1 ; Define active high microswitches

to: M574 X1 Z1 Y1 S0 ; Define active high microswitches

Im not sure where you switches are so I'm assuming they are all on the low end. if not change the axis (x,y,z) number to 1 (low) and 2 (high)

you need one M574 line like this:

M574 X1 Y2 Z1 S0 ; Define active low and unused microswitches

the X1 defined the switch on the low end and Y2 is on the Y highside. and S0 A normally-closed endstop switch. this is the line in my GCode and it works perfect.

i have a Hot end mounted piezo kit from: https://www.precisionpiezo.co.uk/shop. I setup the probe as directed and adjusted the sensitivity properly, but the bed is not stopping when contacting the bed. the wiring off of the piezo board is wired into the z probe header on the wifi board. the wires are as follows: signal, ground, not used, 3.3v.

the signal from the piezo board goes to the z probe pin labled: Z_Probe_In. My Gcode is:

; Endstops
M574 X1 Y2 Z0 S0 ; Define active low and unused microswitches
M558 P1 I1 X0 Y0 Z1 H5 F120 T6000 ; Set Z probe type to switch, the axes for which it is used and the probe + travel speeds
G31 P600 X0 Y0 Z2.5 ; Set Z probe trigger value, offset and trigger height
M557 X15:285 Y15:285 S20 ; Define mesh grid

but when i do a home all the z axis crashed into the bed not stopping. I'm not sure what I am doing wrong. I have verified that the probe is signaling (by blue led on piezo board) but the bed does not stop. am i doing something wrong??

My thermocoupler connection on the daughter board is not working, and I'm getting is the 2000c error reading. In addition the "fault" light is lit on the daughter board. I could not find any documentation on the "fault" light. can someone tell me what it means. I also unconnected all wires to the daughter board turn on the main board and the daughter board fault light remains "on" with no wires connected. I reset the main board a number of time and re-seated the daughter board but the fault light on the daughter board will not go out. suggestion???

That was it. I must have read the wiki a hundred times and did not catch the version of the daughter board. set my G code to 150 and voila, it works. thanks.

So I setup my board with the Duet Thermocoupler daughter board, but i am not getting any readings for "current" except a 2000c and I/O error fault. I read just about every wiki on this site and tried numerous things but nothing changes. i'm using E3D TYPE K THERMOCOUPLE (CARTRIDGE) and have set it in the 0 slot (using 100) on the daughterboard, but nothing i'm still getting the i/o error and 2000c. I did try connecting the Thermocoupler to E0 thermoistore1 on the board and change the G Code to see if maybe the Thermocoupler wire was bad. I did start getting a reading , but it was high like 350c and stable. but it was reading something. so, what does tell me? I'm thinking of either two things; my G code is wrong or the daughter board is bad. As i have tried just about every variation of G code I could think of. I'm at a lost. and i don't know how to troubleshoot the daughter board. I did try taking a wire and jumping over the connection on the daughterboard (read somewhere in the forum or wiki) and still got the same readings. I am open to any suggestions at this point.

NOTE: this is a new printer build, so it hasn't even printed anything yet.
