U axis malfunction
-
Hi,
I've got a problem with the U axis configuration. I've checked the following topic: U axis don't print but couldn't find the right solution for my printer. U axis homes well, but during printing it stays in place or hits the X axis extruder which is waiting in its homing position on the other side of the axis. I cannot get it to print anything. Maybe you wil be able tell me what I did wrong, because I'm on the verge of giving up on the second extruder.The problem occurs always during printing, no matter if copy or multicolour mode.
My configuration looks like this:; Drives M584 X0.2 Y40.0 Z0.0:0.1 E0.5:0.4 U0.3 ; set drive mapping M569 P0.2 S1 ; physical drive 0.2 goes forwards M569 P40.0 S1 R0 T5:5:5:5 ; physical drive 40.0 goes forwards M569 P0.1 S0 M569 P0.3 S0 M569 P0.0 S0 ; physical drive 0.0 goes forwards M569 P0.5 S1 ; physical drive 0.5 goes forwards M569 P0.4 S1 ; physical drive 0.4 goes forwards M671 X-20:220 Y0:0 U-20:220 S0.5 M208 X-5:205 Y0:200 U-5:205 M350 X16 Y16 Z16 E16:16 U16 I0 ; configure microstepping with interpolation M92 X100.35 Y80.10 Z320.00:320.00 E896.15:896.15 U100.35 ; set steps per mm M566 X500.00 Y500.00 Z1000.00:60.00 E500.00:500.00 U500.00 ; set maximum instantaneous speed changes (mm/min) M203 X12000.00 Y12000.00 Z800.00:800.00 E12000.01:12000.01 U12000.00 ; set maximum speeds (mm/min) M201 X500.00 Y500.00 Z200.00:200.00 E500.01:500.01 U500.00 ; set accelerations (mm/s^2) M906 X1200 Y3000 Z900:900 E1900:1900 U1200 I30 ; set motor currents (mA) and motor idle factor in per cent M84 S300000 ; Set idle timeout M572 D0:1 S0.2 ; set extruder 0, 1 and 2 pressure advance to 0.2 seconds (RepRapFirmware 1.20 and later) ; Axis Limits M208 X0 Y0 Z0 U0 S1 ; set axis minima M208 X450 Y500 Z475 U450 S0 ; set axis maxima ; Endstops M574 X1 S1 P"io0.in" ; configure switch-type (e.g. microswitch) endstop for low end on X via pin io0.in M574 Y1 S1 P"io2.in" ; configure switch-type (e.g. microswitch) endstop for low end on Y via pin io2.in M574 Z2 S1 P"io5.in+io4.in" ; configure switch-type (e.g. microswitch) endstop for high end on Z via pin io4.in M574 U1 S1 P"io3.in" ; Z-Probe M558 P0 H5 F120 T6000 ; disable Z probe but set dive height, probe speed and travel speed M557 X15:215 Y15:195 S20 ; define mesh grid ; Heaters M308 S0 P"temp2" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin temp2 M950 H0 C"out0" T0 ; create bed heater output on out0 and map it to sensor 0 M307 H0 R5.187 K0.400:0.000 D41.47 E1.35 S0.00 B1 ; enable bang-bang mode for the bed heater and set PWM limit M140 H0 ; map heated bed to heater 0 M143 H0 S100 ; set temperature limit for heater 0 to 100C M308 S2 P"temp0" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin temp0 M950 H2 C"out2" T2 ; create nozzle heater output on out1 and map it to sensor 1 M307 H2 R2.962 K0.727:0.000 D8.70 E1.35 S1.00 B0 M307 H2 S240 ; set temperature limit for heater 1 to 240C M308 S1 P"temp1" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin temp1 M950 H1 C"out1" T1 ; create nozzle heater output on out1 and map it to sensor 1 M307 H1 R80.490 K900:0.0 D20.02 E1.35 S0.05 B0 I0.5 V23.8 ; disable bang-bang mode for heater and set PWM limit M143 H1 S260 ; set temperature limit for heater 1 to 240C ; Fans M950 F0 C"out9" Q500 ; create fan 0 on pin out7 and set its frequency M106 P0 S1 H1 T45 ; set fan 0 value.

@VA3Dnimers I'm guessing this is an IDEX machine? Is there part of your config.g that is before the ;Drives section? Because you need to define it as an IDEX machine if so, usually using M669. There's also a page here on setting up IDEX machines: https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_IDEX
There are some errors in your config.g. First, all of the following should only have one Z parameter:
M92 X100.35 Y80.10 Z320.00:320.00 E896.15:896.15 U100.35 ; set steps per mm M566 X500.00 Y500.00 Z1000.00:60.00 E500.00:500.00 U500.00 ; set maximum instantaneous speed changes (mm/min) M203 X12000.00 Y12000.00 Z800.00:800.00 E12000.01:12000.01 U12000.00 ; set maximum speeds (mm/min) M201 X500.00 Y500.00 Z200.00:200.00 E500.01:500.01 U500.00 ; set accelerations (mm/s^2) M906 X1200 Y3000 Z900:900 E1900:1900 U1200 I30 ; set motor currents (mA) and motor idle factor in per centMotors on axes with multiple motors must be identical, because they need to share the settings.
Generally, on an IDEX, you set the X limits so the X tool can't reach the tool on U. This usually means there is a limit on how far across the bed each of the tools can move, and both tools may not be able to cover the whole bed. You also have two places where M208 is being set, so these lines also need adjusting:
; Drives M208 X-5:205 Y0:200 U-5:205 ; Axis Limits M208 X0 Y0 Z0 U0 S1 ; set axis minima M208 X450 Y500 Z475 U450 S0 ; set axis maximaAssuming X tool is parked at X0, and U tool is parked at 220, you probably want to limit them so X can't reach to U, something like:
M208 X-5:180 Y0:200 U50:205
Your U endstop is currently marked as being at the low end, ie where the X tool homes:M574 U1 S1 P"io3.in"Again, assuming this is an IDEX machine, you probably want it to home to the max end, so this should be
M574 U2 S1 P"io3.in". What does your homeu.g file look like?M671 only uses X and Y positions:
M671 X-20:220 Y0:0 U-20:220 S0.5Delete the U values.
When creating a tool that prints multiple copies you need to offset the X and U axes; currently they are trying to print in the same place because of the G10 offsets. See https://docs.duet3d.com/User_manual/Machine_configuration/Configuration_IDEX#creating-a-tool-that-uses-more-than-one-carriage-to-print-multiple-copies-of-an-object
M563 P2 D0:1 H1:2 X0:3 F0:1 ; tool 2 uses both extruders, hot end heaters and fans, and maps X to both X and U G10 P2 X0 Y0 U0 S215 R215 ; set tool offsets and temperaturesYou can check that your config.g is formatted correctly, even if the numbers are not correct, by sending
G98 P"config.g". This should highlight some errors in the use of Gcodes.Ian

@droftarts
Hi, thank you for your reply. Yes, it is an IDEX machine.
I've applied most of the changes you listed. However, I still have some issues.
First thing is, after applying G98 P"config.g" I receive Warning: G98: Command is not supportedWhat is more, after changing the offset in
G10 P2 X0 Y0 U0 S215 R215 ; set tool offsets and temperaturesmy X carriage, which worked well, is pushing the end of the axis, no matter what value I apply, example used: X50, X70, X100, X-50, always the same (for U axis always opposites of those values), and U still didn't move.
My homeu.g looks like this:G91 ; relative positioning G1 H2 Z5 F6000 ; lift Z relative to current position G1 H1 U665 F1800 ; move quickly to U axis endstop and stop there (first pass) G1 H2 U-5 F6000 ; go back a few mm G1 H1 U665 F360 ; move slowly to U axis endstop once more (second pass) G1 H2 Z-5 F6000 ; lower Z again G90It is after the changes, because thanks to you I finally understood how to calibrate the motors and which way should they work, so i changed
M569 P0.3 S0into
M569 P0.3 S1And now, at least I think, the directions of the X and U carriege work as they should.
If you have any idea what can I change or what should I post here please let me know.

@VA3Dnimers said in U axis malfunction:

Oops, that should be
M98 P"config.g".Please can you post your full config.g again, so I can see what changes have been made.
For the tool offset:
With the first two tools, you are printing across the same area for each tool, but individually. The X and U coordinate is the same, so that each tool can go to the same place on the bed. The centre of your bed, which is 450 wide according to your M208, is X225.With the third tool, you can only use half the bed for each nozzle; they cannot overlap, or the printed objects will overlap. You only slice one object for the Gcode, but you can only use half the bed width. Then each tool needs to be centred in it's half of the bed. The position of the bed centre is X/Y 225, and the tools need to be offset in each direction by half this amount, ie 112.5. As it says here:
tool offsets are given as the offset of the nozzle relative to the print head reference point, so the signs are opposite to what you might expect because tool offsets are subtracted from the required printing locations during printing.
So I think the offset should be
G10 P2 X112.5 U-112.5. Note this is only for the third, duplicating, tool. The offsets should stay the same ie X0 Y0 (though this may need adjusting to get them to print in the same place) for the other two.Ian

In tfree0.g, you are parking the X axis tool at X10, which is still in the area where the U axis may hit it.
In tfree1.g, you are parking the U axis tool at U/X10, which will be up against the other tool. Park it at U535.When you select tool 1 (using just the U axis), does the tool move correctly?

Changes applied, but still have to tinker with the M671.After choosing the Tool1, but not printing, the only thing that is odd is, when I move the T1 for example to the middle of the bed and move any other axis, the carriage U goes to it's homing position. When this happens and I move U axis even for a 1mm, the carriege goes back to the position before this "odd homing"
When I try to print with T1 only, it goes to the end of the axis and hit the second carriage and prints the line there.
I also was chaging the offset for the U axis a bit to be more precise.

After choosing the Tool1, but not printing, the only thing that is odd is, when I move the T1 for example to the middle of the bed and move any other axis, the carriage U goes to it's homing position. When this happens and I move U axis even for a 1mm, the carriege goes back to the position before this "odd homing"
Are you moving the it using the U axis, or the X? When the tool gets mapped to X with M563 ... X3, it maps the X position to U with any movement. If you move the U axis, it is moving independently of X, so the next time you move any axis, it needs to move back to where X is, ie back to where it is before the movement of the U axis. At least, I think that's what is happening... I don't have a IDEX to test myself!
Is there any part of your config.g before the '; Drives' section? If not, are you running in SBC mode? The only other thing I can think of is if there is a kinematics issue, ie you have a CoreXYU rather than a Cartesian layout. I can't see an M669 command in your config, so I assume it is cartesian (ie a move in X doesn't move the Y or U axes, except when the U tool is selected).

When moving X, it works well. Thank you.
