I’m getting TE2564 error near age start of every 4-5th print with ABS. If I do nothing other than restart it usually works until the next time. It usually happens near the start of a print.
I’ve tried jiggling/reseating the heater connection of the heater wiring but this has not changed things.
Just wondering if anyone else issuing this. Thanks
been getting same issue? any answer
I still have this problem but it’s frequency has dropped to about one in 10 prints and only on higher temp prints.
I might suggest that the OP please remind everyone what the TE2564 error is…Folks might be a bit more responsive if they don’t have to do the research to figure it out on their own time. 
I’m having the same issue. It started immediately after I updated the firmware to v1.1.3.13.
Anybody able to find a fix?
Error TE2564 is “nozzle did not heat up as expected”
Since changing my hot end about 3 weeks ago this problem occurred for the first time yesterday but disappeared on restart.
I’m getting the error TE2564 nearly every attempt. The nozzle is heating up. I’m able to heat it up to 300, however the problem seems to be getting the temperature to stabilize. The heat graph looks like a heart rate monitor with all the fluctuations. After it errors out the light goes out, the print bed drops all the way down and the cfs lights strobe.
I initially had some success by plugging and unplugging the nozzle power and sensor plugs but then doing that didn’t reduce the frequency of the TE2564 arising. I also found I was only getting this error at ABS temperatures so it does appear to be temperature related but then it also happened with a couple of PLA prints. I should have logged the errors -DOH. Then I change the whole hot end and it’s only happened once since and that was on a PETG print.
I have been getting this error more and more frequently the past few months, even after replacing the hotend in early Aug. I print mainly with PLA, sometimes with PETG.
A couple of weeks ago, I changed to printing with the top glass and door closed and always running the calibration steps - the zig-zag one on the left and the block one on the right.
Haven’t had the error since and even took a chance on a 14 hour print that went fine.
It may or may not fix your situation, but it’s easy to try.
