Trying to get IDEX up and running, need help U3 not working

dc42

The U endstop is at the high end of the axis, therefore you need U2 in the M574 command not U1.

Also make sure you have set up the axis limits in the M208 S0 and M208 S1 commands.

I have changed to U2 earlier but was still having issues. I think i had found the problem in the max limit set up but i lost my WiFi and have been trying to get the duet wifi working. I have another duet WiFi and have updated to latest and setup the macro. i am getting a bad command in M587:
M552 S0
G4 P1000
M587 S”Ronald’s Wi-Fi Network” P”lead9376”

Which firmware are you running? Use M115 to check. If it's 1.20beta8 then this is a known bug, in which case please upgrade to 1.20beta8+1.

Please note, the single-quote character in your ssid will need to be sent as two single quote characters in the M587 command. This is because within a double-quoted string, one single-quote character means force the following character to lowercase.

I am using the 1.20beta8+1.

SENT: m115
READ: FIRMWARE_NAME: RepRapFirmware for Duet WiFi FIRMWARE_VERSION: 1.20beta8+1 ELECTRONICS: Duet WiFi 1.0 FIRMWARE_DATE: 2017-11-18
READ: ok

Not sure what you mean about the single quote. Do i need to do the following:

M552 S0
G4 P1000
M587 S”Ronald”s Wi-Fi Network” P”lead9376”

I have tried this and it still returns:

SENT: M98 P/macros/SetNetwork
READ: WiFi module started
READ: M587: Bad or missing parameter
READ: ok

I think you may be using the wrong double-quote characters because the ones in your post are angled. Also, between the letter d and letter s you need two single quote characters, not one double quote. Like this:

M587 S"Ronald''s Wi-Fi Network" P"lead9376"

Cut and paste that line, and try it. I just tried it on one of my printers and it worked. When you send M587 without parameters to list remembered networks, you should see this:

Ronald's Wi-Fi Network IP=0.0.0.0 GW=0.0.0.0 NM=0.0.0.0

Still not working. I will try again later. I may change my SSID to a simpler name and try again.

Are you now using the correct double quote characters in your macro?

You may find it easier to send the commands via USB from a terminal emulator program.

Yes i think that is the problem. I have just received my Duet ethernet and i am connected. I have everything homing but i cannot get the U axis to move once homed. Here is my config on my movement section.
; Movement section
M569 P0 S1 ; Drive 0 goes forwards (change to S0 to reverse it)
M569 P1 S0 ; Drive 1 goes forwards
M569 P2 S1 ; Drive 2 goes forwards
M569 P3 S1 ; Drive 3 goes forwards
M569 P4 S0 ; Drive 4 goes forwards
M569 P5 S1 ; Drive 5 goes forwards
M584 X0 Y1 Z2 U5 E3:4 ; Create U axis for second X carriage before we try to configure it
M574 X1 Y1 U1 Z0 S0 ; Set endstop configuration (X and Y endstops at low end, U endstop at high end, active high, no Z endstop)
M906 X800 Y800 U800 Z800 E1000 ; Set motor currents (mA)
M201 X800 Y800 U800 Z15 E1000 ; Accelerations (mm/s^2)

M83 ; ...but relative extruder moves

Am i missing something?

What driver are you using for the 6th driver (the U motor): the first driver on a DueX2 or DueX5, or something else?

ronnien59

it is on the DueX5

dc42

In this command:

M574 X1 Y1 U1 Z0 S0 ; Set endstop configuration (X and Y endstops at low end, U endstop at high end, active high, no Z endstop)

you have specified U1 which means that the U endstop is at the low end of the U axis. However, the U endstop on an IDEX machine is normally at the high end. So use U2 in that command.

That has solved the problem. I can now start to calibrate. Thanks so very much for the help. I thought i had changed it and then changed it back for some reason.
