[3.5.0 RC3] Printer is realy slow in X/Y suddenly
-
Hi Guys,
I have updated my Setup (with SBC) from RC1 to 3.5.0 RC3.
After starting a print, the machine first homes normally, grabs the tool and then starts to travel extremely slow.
In this state, I aborted the print and try to home again, but it now homes extremely slow also and never returns from this 'slow state'.
Only after a reset, the machine behaves normal until I start the next print.
On the picture you can see the requested speed is much larger than the top speed of the current move (linear in X, ~100mm, so plenty of space to accelerate).
Does anybody have a hint for me as to where to start searching for the cause of this? What is it that can accommodate such a behavior?
Thanks!

Update: I reverted to 3.5.0-rc.2 via
M997 S2 V"3.5.0-rc.2"(thanks for this feature!!!) and now the issue is even more astonishing:
The coordinates of the tool are jumping really fast (a bit like it's simulating), but only the Z axis is moving sometimes and not quite as it should (X and Y are stationary)I will investigate a bit further and try to report on my findings...
-
Ok, so it seems that this strange behavior occurs when printing and even simulating any file.
Note the simulated time of this file:
I cannot wrap my head around what the simulation of a file can change in configuration that homing / moving is extremely slow afterward.
I reverted to 3.5.0-rc.1 via
M997 S2 V"3.5.0-rc.1"(that was my last used version) but now the issue is still present. The simulated time is now complitly off in the other direction:
Can someone try to simulate the following file on his machine with any 3.5.0-rc and report the simulated time / any change in behavior afterward?
I had to truncate a bit of the file in the middle, but the error is still present for me: bad_job.gcodeThanks to all.

@marvineer can you post a bit more details of your setup? It may help @chrishamm diagnose what’s gone wrong. M122 and other logs would help. M997 S2 is a new feature, and not extensively tested.

It's a E3D ToolChanger with a 6HC as main board, a Toolbaord and a 3HC as extension boards.
The config is a little more complex, I published it on GitHub.
The main config file is stated here, but there are multiple macros involved:

@droftarts I have found the issue, I suppose this is one for SuperSlicer...
The g-code exported from SuperSlicer 2.5.59 contains a
M204 P0 T0. This was certainly not the case in the past.I changed the following: Printer Settings > Machine limits > How to apply limits = "Disable"
Before this, it was set to "Use only as safeguards", but that and even "Use also for time estimate" gave an output ofM204 P0 T0?!I tested it with the change and can now print like normal (even on RC3). So case closed for you guys

@marvineer did you file a bug with SuperSlicer?

@oliof I was about to, but someone was faster (issue was from 3 weeks ago). It even seems fixed for the next release:

@marvineer well done for spotting the issue! I had the same problem with PrusaSlicer the other day, though only got as far as simulation, when a normal job that usually simulated to 1hr 15m was going to be 73hrs! Slicers seem keen on supplanting machine configuration.
