First everything prints well IF I increase my documented temperatures by 20 degrees celsius. I recently replace my stock hotend with the E3D V6 and used the new heater cartridge and 104GT thermistor, did a PID Tune and everything looked good until I tried to print. Where I could print PLA at 190 (I mark the individual rolls) I now have to increase it to 215-220 to get layers to stick together. I also find PETG needs the same temp increase. I place a Klien High Temperature Thermocouple under the sock and find the reported temperature on the printer is 25 degrees higher then what the Klien reports. Bad 104GT thermistor ?
That certainly seems too much difference for normal levels of variance (each part has it's own tolerance, so a couple of degrees either way would be 'normal' in my view, so long as it was consistent). It could be a bad thermistor - easy enough to check. If you have a multimeter, measure the resistance of your thermistor - somewhere in these forums is the correct resistance - it has been posted here somewhere, but I don't have time to go find it right now. Also, you probably need to change your firmware settings to tell it what thermistor you have if you haven't already done so - for Marlin, this would be #define TEMP_SENSOR_0 5 (from memory). Hope that helps
Another possibility is that the PID tuning wasn't in still air and/or wasn't repeated a number of times. When I first did a PID tune I had the window open and the readings varied all over the place due to the breeze.
I did the PID tuning with he fan running so I'll redo that. The MPSM V2's code isn't directly edited so I sent M561 P1 followed by M500. This morning the system is throwing errors regarding heating so could it be the cheap power brick?
I think Old_Tafr nailed it, though I'm still testing things look meltier Also the cheap power brick I bought was adding issues as the power cord was not a solid fit and it was disconnecting and reconnecting intermittently. Going to replace that, enough fire hansards with cheap printers already Thank everyone for the help!
