A few prints in and it seems as if adding the M400 to cancel.g addressed the issue. I guess I haven't been cancelling prints on the alpha.. Otherwise all seems to be working as expected.

I didn't have an M400 command after the tool park in my cancel.g file so that may be the culprit. I'll add it and retry but it won't be until tomorrow.

@dc42 I'm not sure what's changed between the last alpha and the current beta but the Jubilee is once again dropping tools even with the M400's...

edit: on a side note it primarily appears to happen after I cancel a print and it parks the tool. At this point I'm reverting to the alpha 5 as it's been pretty solid.

Day 3 without any tool drops so I'm going to say inserting M400 prior to tool lock/unlock macros is working. Out of curiosity, will this be addressed in the final release or will the M400 always be required? It won't matter much for me as I'll likely forget to remove it when the 3.6 is released but I am curious.

A quickie follow up, several prints, maybe 50'ish tool changes and no issues. It appears as if the M400 is helping.

Will try the M400 commands and if they don't help, I'll disable IS at start of tool change and re-enable it after tool is picked up.

Thanks for the assistance

@dc42 I added M400 prior to macro calls for lock and unlock and stuck one in the macro as well... Following are the macros if that helps and a couple of pictures showing the pin when a failure occurs.. Pin should be horizontal when unlocked and stop should be at the limit switch, when there's a tool drop the stepper never reaches the limit switch...

tool_lock.g

tool_unlock.g

; Disengage the toolchanger lock
G91                 ; Set relative movements
G1 U-4 F9000 H2     ; Back off the limit switch with a small move

G1 U-360 F9000 H1   ; Perform up to one rotation looking for the home limit switch
G90                 ; Restore absolute movements

@dc42 One thing that is consistent when there's a tool drop is that the locking pin isn't fully rotated to the lock or unlock position which initially had me thinking there was mechanical binding. I'll stick an M400 before the call to the tool lock/unlock macro to see if that helps. I've reduced my tool change speeds by about 60% to see if that helped and it made no difference, but I'll leave them low until I figure out why I'm not getting proper tool engagement.

@o_lampe I've lowered tool change speeds to see if that helped and it didn't. Initially my rationale for high speeds was to minimize ooze in an effort to eliminate the need for a wipe tower. It didn't work and I never lowered them but have more than halved them the past few days...

@gloomyandy Follow up several prints and a couple of hundred tool changes on 3.5.1, reverted to the latest 3.6.0 A5, (2) prints in and a tool is dropped while pulling away from the parking post. Config.g below

@gloomyandy Will do, switching back to 3.6.5 alpha from this link and will let you know. Ran over 100 tool changes without issue on 3.5.1. I'm going to stick with the 3.5.1 DWC and not use one of the earlier alphas that was released..

@gloomyandy reverted to 3.5.1 and am ~50 tool changes in without issue... Will continue to run throughout the morning and will follow up. I'm thinking it may just be wise to zip up my configuration files and link to them if there's no issues when running 3.5.1. One thing for sure is print quality improvement is definitely noticeable..

@gloomyandy Sorry to be unclear... No issues with 3.5.1 prior to updating to 3.6.0 Alpha. I've not reverted to 3.5.1 yet so can't say for certain it's a 3.6.0 thing yet only circumstantially for now. Will revert to 3.5.1 later to see if it's firmware or other issue.

@gloomyandy 3.5.1 Will revert at some point this weekend or today. The issue with the tool change is that it's so random. I can have hundreds of flawless tool changes other times they'll happen in short periods and of course it's never when I'm looking. As an aside I mostly do single tool prints and sometimes will have a flawless pickup and the tool lock will not fully disengage at the end of the print and will drop the tool as the carriage retracts from the tool posts. Other times the lock will not fully engage during pickup and will drop the tool as it retracts or the tool plate won't be tight to the carriage during print and the tool will kind of flop. My initial thought was mechanical binding in the pin mechanism but the mechanism operates freely. Other thought maybe bad connector or an issue with the stepper that drives the pin that just happens to coincide with the firmware change. I have a print that I need the higher quality for so will get through it and revert and print a bunch of parts that I've been printing to see how it goes. Upside is that it will also give me a baseline to compare print quality between firmwares.

@gloomyandy Timing was on my side this morning... Started a print and went for cup of coffee and came back to the carriage air printing, tool was never picked up and it doesn't appear that the twist lock was ever actuated. Attached video starts at the print being paused while tool 4 was supposed to be attached and printing. Clearly the tool wasn't picked up as it should have been. When I cancelled the print the carriage went to the return position and didn't appear to fully park the tool as the two plates never made contact and the twist lock was never actuated. I'm not sure if this is something in the tool lock or unlock macro or something else, again it's an issue I've never seen before and those macros haven't been "tweaked" in ages. Twist lock moves freely and I can't do anything to make it bind FWIW...

failed pickup video

normal operation

@gloomyandy I'm thinking the same thing or the stepper is failing. The issues happen so fast and infrequently that I don't actually see it happen, only the after effects. I did see one park attempt where it looked like it attempted to pick up the tool about 2cm in front of the tool plate. I have pretty high travel speeds for my tool changes and will try lowering them first and will revert back to 3.5.2 if I still have issues and will go from there. I do have to say in the 3+ years I've been running this machine I've never had tool drop issues.

@dc42 If it occurs when picking the tool up the twist lock doesn't fully engage then the tool either falls off as it pulls away from the parking posts or flops around when printing. When dropped off it's as if the twist lock doesn't fully disengage then the tool moves with the carriage then drops as the carriage pulls away from the parking posts.

Printer is Jubilee with (4) tools MB6HC with (4) Fly-RRF's driving the extruders.

@dc42 I'm starting to get random tool drops when picking up and when parking tools, maybe once every 20 or so toolchanges. Attached are what I believe to be pertinent files... It happens with all tools and has never happened prior to this alpha and have hundreds of hours on the printer. No other code changes were made other than the alpha update.

I had the same issue....

Been printing on and off for several prints and knock on wood haven't had any tramming issues. Print quality is also very much improved over 3.52. Looking forward to further improvements.
