Issues With Support
Anyone having issues with support??
I started having trouble with a issue end of February and it is now march 14 with no resolution. i have been emailing back and forth but sometimes it is several days and no reply. I emailed Friday with a idea of possible malfunctioning part but as of today i have no heard a word. i hope this is a isolated support issue and not a bigger issue of the business growth outpacing support.
Support during sale was excellent but after having some issues and days without answers i asked that the email chain be turned over to a supervisor or someone else to handle since i felt i was getting nowhere and i was denied, i am a patient person but this is starting to make a otherwise happy purchase turn into a bad experience.
I hope someone out there is listening.
Sorry for venting but over 2 weeks is enough!!!
Update, they sent a new PINDA probe on monday so we will see if that fixes the problem i just wish they would have sent a email on monday to let me know
Re: Issues With Support
Neal,
I've had mixed results with Prusa support myself.. but rather than sitting here discussing the quality of the support, maybe lets invest that time into trying to fix your problem?
I checked your other posts on the forum and it looks to me as if you're having issues with getting a good first layer / Z-values change between prints. Is that the problem you're trying to get a solution from Prusa for?
If so,
did you try raising the extruder up before starting a new print? I make sure my extruder is always way up (i get it to Z= 201 after each print). This way, the sensor doesn't get hot during preheating on my next print. I use Gcode in my end script to do so, but for testing you could simply use the Move Axis command from the printer menu before starting the next print.

Ok, thanks for helping!!!
to answer your question yes i have been raising z up 3/4 to top before i heat.
first thing , It printed great for 2 weeks with zero issues, i mean zero. first V2 Cal print and live z adjust and i was printing. Perfect!!! then all of the sudden after 2 weeks i started having problem with the first layer printing. it seemed like it was under extruding filament. past the first layer it prints fine to correct dimensions 1 X 1 X 1 block measures within .002
i took the entire head apart and checked everything i had read could be a problem and it all looked ok, no skipping steps, drive knurl ok, thermal break clear, with no nozzle filament slips through easy, installed new nozzle still the same thing.
I think i have narrowed it down to a PINDA probe malfunction because every time you start it will start with a different Z height and i will have to adjust live Z on the fly to get the first layer to be correct
Any ideas?
Re: Issues With Support
Can you see some short but extreme temperature fluctuation in the display from the hotend thermistor?
It won't extrude when the hotend temp is too low. That's what happend to me. So that "could" be an issue. Reason was a bad crimp connection within the connector of the extension wire for the hotend thermistor.
I'd solder that connection anyway even if that is not the case with yours. There have been several people having this issue. The replacement thermistor I got from Prusa was already soldered and didn't have a connector within. 😉
To verify it you can connect your PC to the printer using Pronterface. There is a temperature graph below the controls. If you click on it it will get a bigger window. If the temp fluctuates you will see it in the graph quite clearly.
Re: Issues With Support
I will check within Pronterface when i get home but i do not believe so as the temps stay rock solid and follow the temp request correctly.
it heats up in a nice and even pace and while printing stays within a couple of degrees but i will look at it pronterface and report back

Re: Issues With Support
Could definitively be that this is not the cause with yours. 😉
But we can just try to exclude possible issues which have been seen out in the field. At least you know afterwards when that is not the cause and have an eye on the next possible one.

sometimes the nozzle will be scraping the bed, sometimes it will be way too high and print wont stick to the bed and then sometimes it will be just right and first layer will be perfect.
I always start the heating with the Z almost at the top of travel away from heated bed so it does not affect the PINDA probe. i wish they were powering it with higher than 5 volts as the accuracy increases with higher voltage, or so i have read and i also watched toms sensor video on you tube
as of Monday prusa have sent me a replacement probe, we shall see what that does

I've been having almost the exact same problem. I've been assuming that there was a problem with the 'Live adjust z' value not being stored/written to the non-volatile memory or something, but I suppose it could be the PINDA probe instead. Did you just ask support for a replacement, or can you order a PINDA probe from somewhere else?
Re: Issues With Support
@Derek, You can order a PINDA from the hidden spare parts section in the Prusa shop. If you can't see it yet, you gotta ask in chat for access.
One other idea that sometimes helps with PINDA related strangeness would be to try and mount it a little lower / closer to the bed. What ist your current Live-Z set at atm?
