problems with second extruder.

terzyans · May 2018

Hi Everybody,
I am having problems with most recent repetier firmware. I tried to find answers to my problem in forum but nothing came up. I upgrated my clone of TAZ to print using two heads. I configured firware online, make necessary changes in pins, uploaded to my MKS Gen V1.3 board.When I tested the new setup. it did not read the temperature of the second heater (which was on temp_2_pin and was connected to A15 pin) . I switched the connector to port temp_0_pin (pin A13) and it showed the correct temperature. I mention this to show that sensor and connections are Ok, something wrong with my Configuration or pins files. Also it does not turn off the second print cooler fan. Initially it was connected to aux1 pin D2. Then I moved it to aux2 pin A9, but nothing changed. The fan spines all the time. I would be very thankful if somebody can help me to figure out the problem.I tried to attach my Configuration and pins files but could not do it. The attach button complains that file is not allowed. I will copy here parts that are related to my problem.

Nobody had this problem.

Since you say you get wrong temperature that could explain why fan is always on. It is on when reported or set temp. is > 50°C.

If you have no heated bed you can try TEMP_1_PIN for second extruder temperature. If not I can not say if pin number is wrong or pin is defect or you set it to digital by using the digital pin number somewhere.

Other analog pins will not work as this is not just a analog pin, but also a voltage divider with 4.7K resistor. If you have such a resistor you can of course make the same schematic for any analog pin by hand.

Thanks a lot for response. Meanwhile i could solve the problem with fan. I switched it to pin A9/D63. Initially I gave pin number 9 as analog numbering and it did not work. Later I gave it as pin 63 and it solved the problem. I decided to do the same with A15. When in pins.h I as TeMP-2-PIN i give 15 it shows 380 degrees and does not react on temperature. When 15 I replace with 69 it shows 32 degrees but again did not react on temperature. I think I have some problem with analog numbering. Is there a way to show that we are addressing analog input. In Arduino I can use A1..A15, while in Repetier when I use numbering with A I am getting an error in compilation.

Thanks Simon

Output pins ALWAYS use digital pin numbers. Analog inputs over ADC are always analog pin numbers. On/off input also use the digital pin numbers.
