Describe your issue: pid_calibrate interrupted
…
Hello…
pid_calibrate interrupted is my error when I attempt to provide this command:
PID_CALIBRATE HEATER=heater_bed TARGET=60
I am basically trying to configure a new heater_mat that stated 12v while purchasing it. If this is not a Klipper issue and is hardware issue, I am trying to figure this out…
Seth
P.S. Anyway, if you see anything in klipper.log/txt, please let me know. I did a continuity test on the heater pins while the wires were attached to my board terminal connectors. I received sound which made think that the wires are okay for heating.
I just got what you are conveying here. High amperage on specific heater_beds may entail tripping circuitry not made for such high loads.
I think my board can handle 20A max but I am not quite sure of the heater_bed(s) wiring so far. I do not know if they are indeed passthrough or an issue relayed to other circuitry.
Seth
P.S. I may have stumped myself into knowing I made a poor purchase w/ this heater_bed item.
Anyway, I am waiting on a reply from the mfg. of the Recore. I think the heater_bed wiring may be passthrough and not an issue but I am probably wrong. I would probably need to alter some circuitry to handle the load.
Also…
I am on the market for a larger heater_bed that I can control off-board in case of issues like this issue when they arrive.
At least the error message does not look like a problem with the heater hardware. It looks like an issue with the temperature sensors. Alas, I cannot tell which one, so I would follow Pid_calibrate interrupted - #6 by Sineos
Thank you. I am going to go w/ the wattage of the heater_bed is too high and my PSU is not handling it well.
Also and luckily, the heater_bed adhesive was cheap. It was easy to remove it from the glass bed.
So, I do no need to invest in another piece of glass. Also, I am going to try a 110v pluggable, heater_bed this time and see if I can relieve some of the current to/from the Recore so I can use it elsewhere.
I measured a bit with 24V beds. What is the resistance of your bed, when you measure with a cheap multimeter connected to your bed? Your bed should only be connected to your multimeter! Please don’t expect a quick answer, I have to find my old measuring data on an old HDD. I have a feeling, what might be the problem.
Hello…I am done. The bed in question has been discarded. W/ the 12v bed powered, I received 12.3 or something in that range or near it when testing the current from the terminal blocks.
Issue one: The old bed is done.
The new bed is a bigger issue. It was hardwired w/ shotty wiring and a loose screw in the housing of the three prong plug w/out GND. Bipolar? Maybe. Bad wiring. Yes!
Seth
P.S. I did manage to get rid of the older bed and almost fully remove it from the glass bed.
This heated_mat for a bed heater, the new one, might not get removed so easily. So, unless I can configure what they have done and solve it, I am sort of stuck w/ this heated mat (BROKEN one) on my bed. Blah.
I am just lucky that this three prong, 115v plug did not arc on me b/c of the loose screw and no grounding. Blah. I am lucky.
