Inability to move Axis

900turbo

X,Y and Z will not move whatsoever , unless I perform a emergency stop in which case X will strangley move to the right. My Z axis uses 3 motors each with there own driver. I believe I have written this into the G code correctly. Any help or advice would be greatly appreciated , Thank You.

droftarts

@900turbo Your drive mapping for Z is incorrect, you haven't specified driver 0.2 with M569 (it's best to specify all used drivers with their own M569), and you're using the same drive for Z and E! It should be in the form:
M584 X0.5 Y0.4 Z0.1:0.2:0.3 E0.6
This may not be correct for your board. Which Duet board is it? Does it have 6 drivers?

Ian

900turbo

@droftarts Im using a Duet MB 6XD so 6 Driver ports and Im also using a 1LC which the extruder motor is wired into. The printer is Core XY.

droftarts

@900turbo Motors driver should be mapped to the CAN address of the board, then the driver. CAN address 0 is the mainboard, so M584 X0.5 is the 6XD driver 5. So the extruder needs to be mapped to the 1LC. As there's only one driver on a 1LC, driver 0, it should be something like M584 E121.0. CAN addressing also applies to fans, heaters etc. See https://docs.duet3d.com/User_manual/Machine_configuration/CAN_connection#using-can-addresses

Also, you can cut and paste text from DWC into your post, rather than posting pictures. This makes it easier to copy your code and correct it.

@900turbo Also, if you are using external drivers (which you are because you have a 6XD), you will almost certainly have to set the pulse timing suitable for your drivers in M569, for each drive. If you post a link to the drivers you are using, we can suggest some settings. See https://docs.duet3d.com/User_manual/Connecting_hardware/Motors_connecting_external#configuring-the-enable-polarity

Also check that your driver is set up to receive step and direction pulses, and that the wiring is correct. See https://docs.duet3d.com/Duet3D_hardware/Duet_3_family/Duet_3_Mainboard_6XD_Hardware_Overview#connecting-external-motor-drivers

@droftarts My other 121 Can adresses have been mapped fine so im not sure why RepRap has done this to the drivers. I will copy and paste everthing I have as I am a bit lost at this point.

Here are the External drivers

900turbo

@900turbo I also checked the DIP switches on the drivers to make sure they are setup correctly which they are as well as the wiriing that follows the Duet guide.

droftarts

@900turbo Change your M584 commands to one line, this:

M584 X0.5 Y0.4 Z0.1:0.2:0.3 E121.0

Taking just the X axis (the others should be the same), the M569 should be something like:

M569 P0.5 S1 R1 T5:5:10:10

The P parameter defines the driver number. The S parameter the direction of rotation.
The R parameter defines the driver enable polarity: 0 = active low (default), 1 = active high. Your drivers look like they are active high.
The T parameter, where Taa:bb:cc:dd, defines the minimum driver step pulse width (aa), step pulse interval (bb), direction setup time (cc) and direction hold time (dd), in microseconds. Referring to the driver manual, these are 1.5us, 1.5us, 5us, 5us. These are the fastest timings; to check it's working, I have doubled these to 5us, 5us, 10us, 10us.

Note that in the manual it says:

Usually, ENA+ and ENA- are NC (not connected). See “Connector P1 Configurations” for more information.

So if you are still having problems, try disconnecting ENA+ and ENA-. This usually means that the motors are enabled as soon as the drivers are powered.

Ian

900turbo

@droftarts I changed the G code to what you suggested and nothing would move then unplugged ENA + and ENA -. I can now control the X and Y axis I still cannot control Z1,2,3. Y seems to hone perfectly cutting out when making contact with the endstop. However X goes the opposite direction to its end stop when asked to hone. Is Z not moving because of how the optical endstops have been configured ?
Thanks for the help so far would be stuck without it.

droftarts

@900turbo There are a number of reasons that the X axis might go the wrong way:

Sending a positive move results in a physical move in the negative direction: change M569 S parameter. If it is S1, change it to S0. If it is S0, change it to S1.
If it is during homing, the endstops might already be triggered, and the axis is trying to move away from the endstop. Test endstops (check this for Z axis not moving, too), see https://docs.duet3d.com/en/How_to_guides/Commissioning#h-8-check-endstops
Endstop is defined at the maximum end, but is physically at the minimum end of the axis. Check endstop position on axis.

Without seeing the full config.g and homing files, I can't tell how it is setup at the moment. Please share those, either by uploading them (you can upload .g files, or add ".txt" to the end so they can be opened in the browser) or by copying and pasting the text into your reply. Also send M115 and post the response, so we know what firmware version you are using.

@900turbo First thing I note is that you have not added the external driver timings to M569 for the Z axis drivers, and M569 driver 0.2 is missing. Change this part to:

; Drives
M569 P0.5 S1 R1 T5:5:10:10                                    ; physical drive 0.5 goes forwards

M569 P0.2 S1 R1 T5:5:10:10                                     ; physical drive 0.2 goes forwards
M569 P0.3 S1 R1 T5:5:10:10                                     ; physical drive 0.3 goes forwards

Your endstops are all defined as low end (ie axis minimum) endstops. Is that correct? All axes in your homeall.g move towards axis minimum for homing. Z is currently homing using the endstops, rather than the Z probe. It should home by moving the bed up towards the nozzle/tool.

NOTE: in the homeall.g, it says things like 'lift Z' and 'move Z down'. These are written from the perspective of a fixed bed (or moving in Y only) and an X gantry lifting in Z. For CoreXY where the bed moves down, it's actually the opposite; 'lift Z' moves the bed down, increasing Z, 'move Z down' moves the bed up, decreasing Z.

Edit: Update your firmware from 3.4.2rc1 to 3.4.5, which is the current release. See https://docs.duet3d.com/User_manual/RepRapFirmware/Updating_firmware

Ian

900turbo

@droftarts I have entered that and updated the firmware to 3.4.5 , The bed is fixed the 3 Z motors move the gantry up and down on belts.

droftarts

@900turbo I just noticed in your config.g that your X and Y axis endstops are set as minimum end endstops, but your homing moves move the Y axis to the maximum end:
config.g endstops:

; Endstops
M574 X1 S1 P"121.io2.in"                           ; configure switch-type (e.g. microswitch) endstop for low end on X via pin 121.io2.in
M574 Y1 S1 P"io0.in"                               ; configure switch-type (e.g. microswitch) endstop for high end on Y via pin io0.in

In the above, M574 X1 and Y1 define the endstop as being at the low end, ie where the axis is 0.

homeall.g Y axis homing moves:

G1 H2 Z5 F6000         ; lift Z relative to current position
G1 H1 X-705 Y705 F1800 ; move quickly to X or Y endstop and stop there (first pass)
G1 H1 X-705            ; home X axis
G1 H1 Y705             ; home Y axis
G1 X5 Y-5 F6000        ; go back a few mm
G1 H1 X-705 F360       ; move slowly to X axis endstop once more (second pass)
G1 H1 Y705             ; then move slowly to Y axis endstop

In the above, the X axis moves towards the low end with X-705, but the Y moves towards the high end, with Y705. Your Y endstop should be at the high end, eg M574 Y1 S1 P"io0.in".

Which is correct? Check that the motors move in the correct direction first. Which is the correct direction for motor movement? RepRapFirmware expects the axes to move using a right-handed coordinate system, because that's what CAD and slicing software uses. Looking from the front of the machine, +X to the right, - X to the left, +Y to the back, -Y to the front. This puts 0,0 where the nozzle/tool is over the the front left corner of the bed. This can be rotated 180°, so that 0,0 is at the back right corner, but it should not be at the back left or front right. If it is, change motor directions, and then set where the endstop is.

Getting the direction correct for a CoreXY is slightly more complicated, because it may mean swapping the motor connections. However, there is a guide for that here: https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_coreXY#testing-motor-movement
