AC Bed Heater Banding problem
-
Running a 110v ac 800w keenovoo with SSR and getting banding on my delta. I originally thought it was that I was using a thin aluminum heat spreader and it was flexing. well today I peeled the heater off and stuck directly to my 350mm x 5mm glass bed. Same result. I've ran a Pid and did M500 but not sure if I did it all right. would like to know where in firmware I can manually enter the results like I did in marlin. I've also loaded all wiring with ferrite shields-no help. I did get the warning that my bed heater is overpowered but doesn't make sense to me that that means anything since I'm connected to SSR. Thanks

if your print with heated bed disabled the is the result without banding ? if so you have to tune your PID better
-
yes when I turn off bed the banding stops. I think I did the pid correctly. I will try again after the print is done.
-
This means you have high temperature fluctuation over a short period of time, no matter if the heater is attached to aluminium or glass, both will expand and contract as the temperatures rise and fall
-
I'm sure of that. I just need to figure out if M500 actually does anything.
-
the only thing M500 do is saving an override file with some variables that will be used instead of the ones in config.g
-
Ok so just noticed I do not have m501 at end of my config. Will add and test
-
It was not having m501 in my config. Works perfectly now. Thanks!!
