Has anyone encountered the toolhead repeatedly going to the front right corner and then slamming back into the purge shoot lever prior to a print… I mean like 8-9 times in a row! I thought it was just the P1 machines but one of my X1C just did it too! I tried vanilla BS with all BS settings and a BS Cube nothing influencing it from my own settings and it still does it. Tried going down one version on the FW but still the same… any ideas?
Let me clarify what I’ve done… I am using the correct printer in slicer, I’ve tried both BS and Orca, I’ve done a factory reset, diagnostics and full calibration, I’ve backed the firmware down, tried different sd cards, checked for nozzle/extruder clogs, rebooted my home network, used a laptop instead of my regular pc, tried different models, tried different Ams unit, tried different filament (just because)…
Did you remove the grey piece of plastic that sits in the top front right of the machine? I experienced something similar to this when I first unpacked my machine, but after removing that grey plastic piece I haven’t had any other issues.
I had some problems like that and it turned out to be dirty carbon rods. They were sticky feeling and would hardly move. Cleaned with alcohol and fixed the issue. I have to clean the rods much more often than they recommend.
i just now experienced this exact same thing after getting weird sounds when the bed moves (mostly down). Doing a self check right now!
And nothing turned out, sadly. Does this happen every time before you print? And if it happens, does your print start eventually?
Print does eventually start after a bunch of slamming around… question… did you happen to do any upgrades to the ptfe tube tunnel thing that goes into the tool head? I think I’ve narrowed it down to the 2 little screws that hold it in place we’re just a bit too tight and somehow we’re causing a sensor or something behind the plastic they screw into to malfunction.
i do use a ptfe tube guide, but ive installed it probably two months ago, so i dont think thats the cause? after the self testing i did a powercycling and now my print started just fine, really weird!
I have the same problem on P1P and P1S (Almost brand new). They keep slamming into the side no matter what kind of setting I do. Have you solved your problem?
Did you happen to add a “recommended” piece to the tool head where the ptfe tube goes in? I found that when I added that printed part to “help” straighten the ptfe tube, or to help keep it from misaligning the filament feed, that I accidentally over tightened the 2 screws. Once I backed them off a little everything worked not]rmally again.
Any resolution to this? My printer is starting to do this as well and I can’t seem to find a fix. I have tried rolling firmware back and power cycling and calibrations so far nothing has worked.
Make sure that the printer can fully home in the front right corner. It seems to be setting the home point a little early. The printer doesn’t home with a switch, it uses sensorless homing which means it sets the homing point when it encounters resistance in that axis. A slightly shorter ptfe tube can cause this, or a small chunk of filament wedged in the corner. Take the top off and manually move the head to the right front corner to check if there any obstructions.
Unfortunately, it’s nothing as simple as that. I have the original PTFE installed but I did ensure it can reach all the corners. I have done a factory reset; I have rolled back the firmware, checked the connections in the toolhead and replaces the nozzle. Switched plates and cleaned the LIDAR which is not at times saying it can’t read the bed. Maybe LIDAR went out? Maybe a board went out? too many variables and very costly to just try parts and see.
