T15 solved. RC2 was dont calibrated, I did calibrate RC2 for T210 to get real temp thats why dont identify T15. T15 tip temp is very accurate 300c on display real 299c Very happy. But T210 real temp difference is huge.... Today I got OEM mosfets will change and project done! thank`s again for Sparky!
Some peopel ask about my modification, I will add some pictures and video (calibration mode) few days later because I want to clean pcb boards with Ultrasonic to get factory looking
oled 2.42 issue solved. replaced 100uf (vcc line) tantalum cap on oled board with 330uF. On the front board add cap 3300uf on vcc oled line, add ferrite core on wiring oled. Add caps 3300uf on vcc3.3 and -0.6v lines. No I can say there is no jumping at all +-1 very good. Sparky has build very good device, but for dc filtering caps should be higher value.
what about alloy melting temperature, if display shows 300c it does not melt alloy (real 200c). 320c on display (real 220c) starts melting.
what about t12 I will check U2B pin5 I dont like this IC from aliexpress and plus I got used part also its good idea connect only resistors and check on calibration mode it identify or not ID. Very difficult get SUD50P10 and IPD053N08 from suppliers. In my case IPD053N08 I am sure not OEM part. I am from EU shipping from USA suppliers cost too much. May some are alternatyve parts with the same spec?
3. No instrument t12 clone tips 4. I have temp tester for iron tips its very good and accurate. temp difference is huge but If I adjust rc2 I can get real value.
Strange issue also with ssd1309 2.42 oled. If I connect 2.42 oled acdc and resistance on calibration mode jumping +-15 is definitely abnormal... 3 pads on the back (front board) are shorted, wiring is good. Saying because with 1.3 oled jumping +-2 (normal behaviour as u say). Also if I add cap 820uF on 2.42 oled vcc 3.3v and gnd jumping +-6, better but not the same as 1.3 oled -+1. If I disconnect vcc line and use separate external power source 3.3v to drive 2.42 oled its fine its the same readings as on 1.3oled jumping +-1 What could cause this interference???
Hi everyone, I have build controller and I have few questions..
1. Does calibration current should "jumping" from 302-382 uA? Could be issue back board? output mosfets are from Aliexpress not sure they are 100% genuine.
2. Does normal ACD current and resistance jumping +-1 (calibration mode)
3. Can not identify chinese T12 clone tips. May someone has firmaware for clone T12 tips?
4. JBC T210 tips reorganize fine but real temperature -100c. Where can be an issue? anyway with rc2 I can adjust real temp, but where is the point calibrate with 10ohms resistor?
Very happy. But T210 real temp difference is huge.... Today I got OEM mosfets will change and project done! thank`s again for Sparky!
