I have a P1S with an AMS. I usually print PLA, and when I do the bed reaches the desired temperature (55 degrees) as expected, and the print proceeds.
Trying to print PETG for the first time today, the bed never reached the target 70 degrees and the print process did not proceed past the bed preheating stage. Repeated attempts, including after powercycling the printer, gave the same result.
Testing this outside of the print startup process, I’ve manually set the desired bed temperature to 70 and 75 degrees. In either case the bed seems to stop short of reaching the desired temperature. 68 degrees and 72 degrees respectively.
Notably, the icon that is displayed when the bed is heating up in the Handy app disappears at this temperature, so it’s like the printer thinks it’s at the correct temperature even though it isn’t.
Has anyone else experienced this? If this were a kit I’d built I’d suspect that the PID tuning is off and re-calibrate, but I don’t think I can do that with the P1S.
That is quite unusual. It should reach those temperatures with ease.
If manually heating the bed is not working, you can rule out the slicer config.
Since it is actually heating it’s not likely a connector issue.
Waiting long enough after starting the print from the mobile app gave me the error discussed in that link. Sending the same file directly from the slicer worked as expected.
I’m experiencing the same issue. I haven’t printed in a while and it prompted me to update the firmware to 1.0.8.2 which I did. On my first print with a model in PETG it never started. Looking at the status the printer was heating the bed to 69 degrees and never reached 70 degrees and wouldn’t start the print. I down graded the firmware to 1.07 after reading Reddit posts on the issue. The print started and I noticed that the bed still stated the temp was 69 degrees. Watching the bed temp it seems that it does go up to 70 and back down to 69 throughout the print. It appears 1.08 is more stringent on being at 70 before starting and for some reason the printer won’t stay at 70 degrees consistently. I’m thinking the bed and sensor are fine and a tolerance setting needs to be adjusted in the firmware. Maybe increase heating to 70.1 to maintain 70 through the print if the software is going to be sensitive to bed temp before starting.
