And the same for reverse, so on tool change or end of print, lover the bed a bit and then move extruder to dock? End is fine as I can say :

M83               ; relative extruder movement
G1 E-2 F3600      ; retract 2mm
G91               ; relative axis movement
G1 Z3 F500        ; up 3mm
G90               ; absolute axis movement
G1 X30 Y-30 F6000 ; move the X carriage in front of dock
G1 X0 F6000       ; Move the X carriage into dock

Just need to figure out how to do this on start or in tpostx.g so that I assume I would

; lift the head
G91 ; relative positioning
G1 Z5
G90 ; absolute positioning

But have that G90 occur AFTER the move to first G1 in the gcode file (or something, obviously this needs to be absolute too in order to start).

Apologies if this has been covered before, after hours searching I gave up.

After years away from using my machines, I lost my S3D profiles after changing laptop. I have decided to stop using scripts in S3D (Start, Tool Change, End) and do it in Macros as much as possible and let my DuetWifi(s) decide what to do.

For the most part I have it all working perfectly (ish) except for 1 thing which I can't figure out how to achieve.

When I was using scripts in S3D I had it so the bed would lower by 20mm, move the active extruder to the next start point raise the bed to the correct high for that layer and begin.

How do I achieve this in just macros? Can this be achieved.

What happens currently is the tool heats up, when ready the bed lowers 20mm then instantly raises back up then moves to position and begins the layer. This while not causing me an issue at the moment, scares the living sh** out of me every time as the nozel is 0.24mm from the build plate as it zips from dock to first position.

Is there anyway to achieve lower Z axis a bit, move to start position in gcode and resume absolute positioning? And the same for reverse, so on tool change or end of print, lover the bed a bit and then move extruder to dock?

Apologies if this has been covered before, after hours searching I gave up.

Yep that works. Tested in my tfree0 and 1 and works as i expected. At end of a tool usage it waits for the active tool to cool a bit so stops oozing out my volcano, wipes and switches tool. This will prevent alot of random oozed filament from being dragged about and falling off randomly.

THanks!

Thanks! I Will use with caution.

Hello Again,

I have just updated to 1.20 Released and want to give this a go now (found some time at home)…

Can you confirm the syntax for putting the tool into standby. is it:

T-0 P0 ; Put tool 0 into standby
T-1 P0 ; Put tool 1 into standby

or

T-0 P0 ; Put tool 0 into standby
T-0 P1 ; Put tool 1 into standby

Or something else?

Happy new year! (bit late I know)

Hi dc42, Did your change make it into 1.20beta2? I have not tried yet but just confirming.

If so, to put the tool into standby in the tfree macro do i just do T-0 P0 to put Tool 0 into standby and T-1 P0 to put Tool 1 into standby? Also, not that i requested this of course, can you put the tool into standby and wait until it hits that temp (wait to cool), if not i can put a wait in after the T-0 P0 for a set amount of seconds.

I checked the release notes but did not see it so just want to make sure it made the cut.

Thanks! Ill keep an eye out for it!

That would be great, thanks!

For completeness this is my tfree0 macro:

M83 ; relative extruder movement
G1 E-2 F3600 ; retract 2mm
G91 ; relative axis movement
G1 Z3 F500 ; up 3mm
G90 ; absolute axis movement
G1 X30 Y-30 F6000 ; move the X carriage in front of dock
G1 X0 F6000 ; Move the X carriage into dock
G1 E15 F3600 ; extrude 15mm
G1 E-2 F3600 ; retract 2mm
;insert standby of tool code here;
G4 S10 ; dwell for 10 seconds (adjust as needed to when ooze stops)
G1 X30 F6000 ; move the X carriage in front of dock
G1 X0 F6000 ; move the X carriage into dock
G1 X-13 F6000 ; park the X carriage at -13mm

Thats what i tried but but the dump bins are not at the max park position so when tool one moves to max park position it wipes of what has oozed but then continues to ooze outside of the dump bin until that tool has cooled. Sometimes this results in the ooze falling of during the print of the next tool which after awhile ends up in a collection of mess or on next tool selection, when i move that tool to the dump bin to re-heat, it flicks off outside of the dump bin.

If there is not a way to call standby from within tfree then at least i know i need to think of another solution.
It might be possible to redesign the dump bin for the left tool but not possible with out modifying the frame for the right tool.
What about lowing the temp relative to the current temp? So lowing by 40c relative to what ever the current active tool temp is? Is that possible by Gcode?

Hopefully an easy one.

I am attempting to control oozing on took changes on my IDEX system.

What i would like to do is in the tfree macros,
Move the tool to the dump bin,
Place the tool into standby,
Dwell for 10 seconds to let the nozzel ooze while the temp of the hotend cools and it stops oozing
Wipe
Move out the way

How would i put the Tool into standby?

The standby temp is set in the slicer depending on the material so i do not want to set a standby temp, just activate standby temp that has already been set in the starting script.

Is there a way to active the standby temp for a tool from Gcode?

@andyvirus:

Thanks! So far all working great. Quieter Z movements too as an unexpected side effect. Happy customer

I'm glad you're happy. You might care to share your experience on the E3D BigBox forum, because I don't think I've read of anyone else driving the two Z motors in a BigBox independently.

Done. Quoted you post on the E3D BigBox forum anouncing the leveling fearture using 2 or more motors.

@dc42:

You should only put G30 XY coordinates in bed.g that the probe (not the nozzle) can reach.

With an X offset of -33 in the G31 command, the head will be moved to the X offset you want to probe minus the -33mm; in other words to the X you asked to probe plus 33mm. So when you asked it to probe at X=270mm, it tried to move the head to X=303mm.

Ok makes sense. Probe not Nozzle. Got it. Thats what i was mistaking. Thanks!

Hi DC42, will do! Just upgraded to a MGN12 Rail for IDEX so will bring it up there too.
I have just found an odd issue with G32 though that you might be able to help with:

In my bed.g i have:

[c]G30 P0 X20 Y100 Z-99999 ; probe near a leadscrew was x32
G30 P1 X270 Y100 Z-99999 S2 ; probe near a leadscrew and calibrate 2 motors[/c]

and in config.g: [c]G31 X-33 Y-5 Z0.58 ; Set Z probe trigger value, offset and trigger height (IR Probe)[/c]

It seems that on the first probe it takes into account the z prob offset i set in G31 (Z-33) - Great
On the second probe it tries to move to 33mm more to the right than is possible. For now i have set the second probe (right) to 237 to compensate.

Maybe I am using G31 wrong but seems to work perfectly in G29 (respects limits minima and maxima).
I have an IR sensor on X carriage which is 33mm to the left of the nozel (now, was at rear 60mm Y).

Hi Strips, I am on 1.19.2. I will take a look at what you have done!

Thanks! So far all working great. Quieter Z movements too as an unexpected side effect. Happy customer

the bed is on 4 rods, the z motors are center left and right of the bed (Bed is 300x200, lead screws are adjacent to X150 Y100 either side of the bed). It would level left to right. Yes front to back would still need manual adjustment if that went out of alignment but for me that rarely happens, what does happen is i wipe the bed down and if the motors have no holding current one side goes marginally out. This would fix this.

tested the above and it works a treat. never had the left and right side in such perfect alignment

My question about M569 and M906 (motor direction and voltages) is my only real question now… it seems to work fine but just want confirmation. Also speed and steps M201 and M203 and I guess M566? Do i need to reference the aditional driver at all and if so, how. If not, please could i have confirmation as i dont want Z1 all set correctly and Z2 out of step speed, voltage etc wise.

Hello,

Before I try and change my config files to use 2 independently driven Z motors, can you give my proposed config files a once over. I have read https://duet3d.com/wiki/Bed_levelling_using_multiple_independent_Z_motors and it makes note of M584 and M671 which is all fine and i think I understand that (hence sanity check below config.g) but what about M569 and M906 (motor direction and voltages)? Do these need to be defined for the new driver or is that taken care of by M584?

Is the below all I need to do (forget the bed.g for now, that seems strait forward) or do i need to add another line for M569 and M906?
I have connected the second Z motor to Duex_5 port labelled E3 HOT.

Ok, removing the G1 Z-999 S1 has resolved it. Thanks!

I just ran M999, then homed X then Y, then moved Z up to just below the ir sensor then homed Z and it works fine. It is just failing to home Z when the bed is more than say 10mm away. It just gives up and states "G28 Z Error: Z probe was not triggered during probing move."

So it is this bit that does not work at all anymore….

G91
G1 Z-999 S1 F3600
G1 Z3
G90

So if i home X and Y and move the ir sensor to X150 Y100 then send a G91 for relative positioning then G1 Z-999 S1 F3600 to send the bed up to the zmin endstop (ir sensor on x carriage) it does not move. This may be why it worked before and not now is G30 has a probe movement limit (as it seems to )...as it is the G30 command that is genrating that error.

Any ideas?

@dc42:

Have you deleted the deployprobe.g and retractprobe.g files as described in the 1.19 upgrade notes?

The homeall.g file suggests that you have both a Z min endstop switch and a Z probe. This seems odd - have you? If not, see #1 at https://duet3d.com/wiki/Common_problems_and_their_solutions.

The command G28 Z runs homez.g, not homeall.g.

What part suggests a min and max endstop? I only have an IR probe on Min (on the x carriage). I cant see where i have specified a max endstop.
