Dear community,
I am using Arduino Mega and RAMPS 1.4 for creating a custom control (without using MARLIN) for the extruder. I am using a Dyze Design Pulsar which is using 3 heaters. I have connected respectively to the D8, D9 and D10 ports. In my code I have a PID which is managing the 3 temperature sensors and heating independently the 3 heaters. The issue is that at the beginning all the 3 heaters should turn on and I am raising up all the 3 pins with digitalWrite(). The issue is that only one effectively is working. It could be a problem to turning up all the 3 together?
Also I have notice that in all the RAMPS that I have D9+ and D10+ are shorted.
Thank you so much
