      @Chriss Okay, thanks. I've asked for it to be tested, as I don't have a tool changer or multiple tool machine.

        @droftarts So we have misunderstood us. I have this:

        tpost0.g:M116 P0
tpost1.g:M116 P1
tpost2.g:M116 P2
tpost3.g:M116 P3

        So every tpost has a "M116 with Px" accordingly. I can remember that I stumbled over that when I started to write the config and the effect is present with that config.

        We agree that we want to M116 in the tpost, don't we?

        Cheers, Chriss

        Edit: I just saw that "M116" only (without the P) has effect to the current selected too only. I'm not sure that this is correct. I can remember that I added the "P" later because I saw that "waiting for standby" in the past. But it could be that there was a firmware update since than and all of my memory is not valid anymore.

          @Chriss Maybe it should be just M116. According to this change in 3.5.1 https://github.com/Duet3D/RepRapFirmware/wiki/Changelog-RRF-3.x#reprapfirmware-351-stable-changes-since-346

          M116 without parameters only waits for slow heaters (beds, chambers) and for the selected tool heaters of the current tool (if any) assigned to the current motion system. In previous versions, M116 waited for all heaters to reach their target temperatures

            @droftarts Good morning Ian,

            I gave it a shoot but with the very same result. The active tool waits till the tool which went into standby reached the standby temp.

            And that "new" (3.5.1) behavior does not seems to make much sense to me to be honest.

            It would be far more logical to me to have:
            M116 = wait for all
            M116 P0,1,2 = wait for the list of tools
            M116 P-1 = wait for all
            And maybe a other switch like: "X0" = do not wait for standby temp at all. There are maybe some very rare edge cases where you want to wait till the temp went down.

            Cherrs, Chriss

            Edit: I was unable to resist and had a quick look into the current code (well at 3.5-dev), I have to admit that I do not fully understand how that value of P is handed over:

            if (gb.Seen('P'))
        {
         // Wait for the heaters associated with the specified tool to be ready
          if (!ToolHeatersAtSetTemperatures(Tool::GetLockedTool(gb.GetIValue()).Ptr(), true, lerance, gb.IsFileChannel()))
                      {
              return false;
                        }
                          seen = true;
                 }

            I do think to use "H" in the meantime, that looks a bit more promising:

              if (gb.Seen('H'))
              {
                // Wait for specified heater(s) to be ready
                uint32_t heaters[MaxHeaters];
                size_t heaterCount = MaxHeaters;
                gb.GetUnsignedArray(heaters, heaterCount, false);
                                        
                for (size_t i = 0; i < heaterCount; i++)
                                                                                        {
        if (!reprap.GetHeat().HeaterAtSetTemperature(heaters[i], true, tolerance, gb.
                                        IsFileChannel()))
                       {
             return false;
   }
         }
                seen = true;
           }

              @Chriss Thanks for checking the code! The code in 3.6-dev looks the same: https://github.com/Duet3D/RepRapFirmware/blob/5c06d3b1e200de8c7cc2b70f00d9234a28f49fea/src/GCodes/GCodes2.cpp#L1940

              @dc42 will need to have a look at this.

                @droftarts Hi Ian,
                I had the hope to see how the value of P is handed over. The "GetLockedTool" seems to me like it is pointing to the attached tool. Anyway, just guessing. I guess that David can point it out here.

                I have the feeling that we end her in a feature request and I will work around that with the H parameter. It seems to me that H will do what I need too.

                Cheers, Chriss

                  @Chriss @dc42 tested M116 last night, and found it to be working correctly from his tests. These were very simplified, please could you try the same?

                  Test 1 (tested with 3.6.0-beta.4 in standalone mode):

                  • T2 heater is on an expansion board, T1 heater on the main board. But it shouldn't make a difference where the heaters are because the main board does the waiting.
                  • File tpost1.g has M116 P1 in it
                  • Temperatures set manually in DWC. T2 to 195/140, T1 to 100/100.
                  • T2 selected manually, and wait for it to heat up
                  • Run this macro:
                    T1
G1 X-50 Y-50
                  • Macro selects T1 which has active/standby temps 100 and 100
                  • Followed by a G1 move, which happens immediately, with T1 at temperature, and T2 still cooling down from 195.

                  Test 2

                  • temperatures manually in DWC. T2 to 192/140, T1 to 110/100, in case having to heat T1 makes a difference
                  • Worked correctly. After selecting T1 it waited for it to heat from 100 to 110C, then moved and the machine went idle. T2 was still cooling down through 180C.

                  Notes fro dc42

                  • I've looked at the code several times and I really don't think there is a problem with it. Are we certain that the user doesn't have more than one M116 command for each tool? Or could it be that he has a heater that is shared between tools, and that is complicating the issue? (I said no, I don't think this is the case)
                  • Has he tried running M122 while he says the tool is waiting to cool down? It should report under GCodes which commands it is waiting on. (Please try this)
                  • There is no difference in how tool change is handled in SBC mode, it's all handled by RRF, so this shouldn't be different between SBC and standalone.
                  • Please test with the new tool active and standby temps set the same, like dc42 did. If that works OK, try making them just slightly different.
                  • M116 P# is working correctly for me.

                  And perhaps most importantly ... !

                  • Maybe his slicer is inserting temperature commands for the old tool or its heater? (Please check the gcode you're running to see if this is the case)

                    I had some temperature challenges with my tool changer and found I had some temperature settings in my filament config.g file which I was calling via M703 and those were messing me up. But I don't see any M703 in your tpost.g.

                      @mikeabuilder Thanks for the input, that does not apply to me, I do not use any filament specific config.

                        @droftarts Hi Ian,

                        Thanks for your comment. The Slicer is the very first thing I checked, I do not trust the Prusa slicer at all. 😉

                        I was off for some days. Give me some days for the test you and David asked me to too. It may be the case that I made a mistake with the config of the heaters/tools. That could be a very good explanation.

                        I will come back to this thread.

                        Cheers, Chriss

                          I configured T0 and T1 to be at 195/100, I activated T0 via the CodeConsole, waited till it was heated up. Changed to T1 and executed M112 via the DWC console:

                          I was a bit unsure because it looks OKish to me. So I did the same similar test: (same temp settings)
                          T1 was active
                          I changed to T0 via the CodeConsole and I was not able to enter any command on the CodeConsole. So I tied to move the tool via the DWC console (G1 Y100) and the head was moving before the the T1 reached its standby temp.
                          The CodeConsole on the PI was responsive as soon as the T1 reached its standby temp.

                          I will do some of the other tests soon, this is just an update.

                              I write a tiny macro

                              t0
g1 y100 x100
t1
g1 y100 y100

                              I started the macro via the DWV, T0 was active wen I started it. The tool drove to y100 x100 picked up the new tool and the head stopped after the pickup and I executed M122 via the CodeConsole

                                I have the same behavior with the "P0" and "P1" at the M116. And It is till the case that the tools starts moving as soon as I change the standby temp close to the current temp of the previous tool. So M116 is definitely waiting for the previous tools standby temp. 😞

                                I will continue doing the tests...

                                  @Chriss I have reviewed the code and I believe there is a bug in that M116 with no P parameter may incorrectly wait on some additional heaters to reach temperature. However, the code to implement M116 with P parameter looks good to me, and that is what I tested (and failed to find a fault with).

                                    @dc42 Hi David, I apologies for the late reply, I lost the focus on that problem.
                                    I will retest it with the P parameter tomorrow. But I can tell you that I had the P parameter in the config at the very beginning and I experienced the issue.
                                    Anyway, I do understand the concept behind the M116 in this way:
                                    "M116" = Wait for every active heaters on the active motion system. That may indicate that all tools at a toolchanger are infected because they belong to the same axes. But that is is not clear to me why it should wait for the standby temp at all. But this is a philosophical question.
                                    "M116 Px" = That waiting should affect the selected tool.

                                    So it was logical to me that I should use the "Px".

                                    The only thing which I have not tested yet is the H parameter. That could do it in this case too, I may need to test that. But anyway, it would be good retest "Px" again to make sure that it works as it should.

                                    Will let you know more tomorrow.

                                    Cheers, Chriss

                                      @dc42 Hi David, I just tested a bit with a very simple setup:

                                      tpost0.g

                                      ; tpost0.g
; called after tool 0 has been selected
;
; Wait for set temperatures to be reached
M116 P0

                                      tpost1.g

                                      ; tpost1.g
; called after tool 1 has been selected
;

; Wait for set temperatures to be reached
M116 P1

                                      test_macro.g

                                      t0
g1 y100 x100
t1
g1 y100 y100

t-1

                                      And I configured T0 and T1 via the DWC to 205:100. And you guess what? The problem is gone now. 🤔

                                      I have to admit that I do not know how I felt into that rabbit hole at the beginning. I swear that I experienced that. I can remember that I was on the phone with the first time it happened and I spoke with him about it. (Yes, I just called him for confirmation) But I do not know what I have changed in the meantime.

                                      It could be that I configured T1 at that time, I simply don't know and I see no big benefit in speculating more.

                                      That made me to look a bit closer in the slicer generated g-code:

                                      ;AFTER_LAYER_CHANGE
;8.3
G92 E0
;_ON_LAYER_CHANGE LAYER=41
G1 E-.2 F7200
; Filament-specific end gcode
G10 S100 P0 ; set temperature ;cooldown
; ##### Chriss
T1

; ##### Chriss END
; Filament gcode
G10 S210 P1 ; set temperature
M116 ; wait for temperature to be reached
G1 Z8.5 F3000
G1 X111.499 Y113.02 F9600
G1 Z8.3 F3000

                                      You can find my tool change gcode from the prusa slicer in the lines 8 till 11. I tested with the slicer generated g-code and the "problem" is back. So I can confirm now that the slicer generated M116 from line 14 is stopping the printer and the printer waits till the old tool has reached the standby temp.
                                      The firmware is still 3.5.4. So my understanding is that the sentence form the M116 docu: "Note that in v3.5, the scope of tool heaters to wait for is limited to the heaters of the currently selected tool of the selected motion system." is not fully tue, isn't it? So I guess that I run into the bug you mentioned.

                                      Cheers, Chriss

                                        @Chriss yes, that sounds like the reason. That bug is fixed in recent 3.6.0-rc firmware builds. The latest is rc1+2 at https://www.dropbox.com/scl/fo/y03luwmbypirbxncla3rk/AAJFLPFsVdFylemyhkXsAac?rlkey=7cq4svp4rzl2ztdffpzq2ghjk&dl=0 but if you use these, you will need to get DWC from the 3.6.0-rc.1 release.

                                          @dc42 Cool.. thank you very much! I will consider to do the upgrade in the next days. The printer is still in the build phase and I have a lot of other things todo anyway. So I may wait, let's see.
