RepRapFirmware 3.6.0-alpha.4+3 available for testing
-
@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..
-
@edsped Before you do that I suggest that you test with the latest version of 3.6 (after running 3.5.1 for a while to be sure that you do not get any further problems when changing tools).
-
@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 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

@edsped Maybe you could disable IS during toolchanges?
The acceleration on short tracks is different now and moving on the edge to make the toolchange as fast as possible might have flaws now and then... -
@edsped another thing that may help is to use M400 between critical moves of a tool change, for example between the pull-in move and the locking motor move when picking a tool up. Using IS in 3.6 will overlap adjacent moves to some extent. So in this example, the lock motor will start to move before the pull-in has completed. This may or may not matter, depending on the speeds of the moves and the type and frequency of IS in use.

@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...
-
@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.
-
@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...

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

I want to chime in and report that the 3.6.0 5+1 alpha has been working well for me. I have not run any long prints, and I don't probe or tool change, but I changed over from 3.5.1 because I was hitting suspicious layer shifts at well below expected accelerations for printing moves only (not for travels) in speedboat testing. I have run 25 prints since changing over Sept 3rd, along with various non-printing tuning and tests, at accelerations from 50-200k and in-print speeds up to 900mm/s, on a 6WD delta at 400 steps/mm (6HC with a 3HC running a 2WD extruder), as I've been working into the three-minute range on regulation boats. (Yes, it's not a particularly useful pastime, but my machine is finally finished and I've gotta do it once -- plus I'm hoping it's a useful stress test of the new motion stuff in 3.6.0.) The new IS melts down print crispness at these accels, but after some deep breathing I've concluded that's not a bad thing -- if you want crispy prints, the answer is to print in the accel range that's sane for your machine, anyway.
Part of my testing has been aimed at stress testing the delta segmentation change -- I've tested from 100 to 400 seg/s with 0.1 to 0.2mm segment length, as well as accidentally 0.1seg/sec and 400mm min length, and apart from the latter booboo there is little observable difference in quality at high speeds and no difference I've yet found in terms of speed ceiling. I have found that high speeds with high-poly models are causing reports of underruns in the first array slot and, sometimes, very small numbers of LaErrors -- e.g., a 67-layer test vase print with a portion that is a 200-segment, 10mm-diameter circle, sliced at 350 x 100k x 20 jerk consistently reports back underruns [800+,0,0] -- but I don't have comparison data from before I updated, so I don't know if this has anything to do with the alpha. I do know that the circle in that stress test print shows evidence of slowdowns starting at about the same segment count as the move queue length, and that extending the queue length with M595 causes proportionately more reported underruns. (I changed SD cards, just to see if the originally-supplied card with its 4kb clusters was an issue, but a new 32GB card with 32kb clusters did not change anything.) For my foolishly-fast speedboat runs, I've dodged the issue by enabling Arc Welder, which seems to work just fine.
To date I have yet to see a single reported hiccup, regardless of LaError or underrun counts.
I hope the above is useful!

@Kiolia not really, just watch out for changes in behaviour. The only bug I am aware of in 3.6 that is not in 3.5.3-rc.1 relates to expansion boards and homing moves.
-
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.
-
@edsped I haven't decided yet. We'd need to either disable IS throughout tool change files, or implicitly wait for motion to stop between certain pairs of moves - but what pairs, exactly? I'm not sure that either of those would be appropriate in all circumstances. We could add a means of specifying that a certain axis is used as a tool locking mechanism, but would that be any better than advising users where to use M400?

If people don't want to sprinkle M400s, they could also disable and re enable IS at the beginning and end of the macros.
-
@oliof yes. I am considering extending M593 to allow IS to be turned off and then turned on again without needing to specify the parameters.

Okay, I'm back with a problem report with my delta. I noticed during extrusion "blob" testing tonight that it was making a light clunking noise during each blob extrude. At first I assumed it was the extruder, but it was happening on all the blobs, and doing it the most on the lowest cubic (slowest) ones. To judge from finger-on-arms, it may only be the Z axis (AWD, so this is two steppers). IS on/off does not affect it. It is reproducible without extrusion, too, using a very slow move with Z component like G1 X3 Y1 Z20.5 F16.84 starting from X0 Y0 Z1. There is no discernible interval to the clunking; it sounds random, and it happened at least once on most of the blobs, which were done across the bulk of the bed area. M122 shows nothing amiss to my eyes. I can confirm that this wasn't happening with nigh-identical GCode in 3.5.1. I think I've seen this or something similar reported already, but I thought that was connected somehow to IS, and this doesn't seem to be.
