[ISSUE] Trying to exchange pins D45 and D7 on Trigorilla #46

Closed javilonso closed 3 years ago

javilonso commented 3 years ago

This might be a help issue rather than a bug issue.

I want to interchange pins D7 and D45 in Trigorilla board. From factory, D45 is Heater 1 port and carries the led strip. On the other hand, D7 is the FAN1 port and carries the layers blower fan.

I need to exchange this 2 ports because I need the blower fan in port D45.

Both ports are pwm, so there is no problem for that.

I tried to change ports in /src/pins/ramps/TRIGORILLA_14.h, but that is not working because from the screen when I press LED Icon, it activates the blower fan.

Hope someone can tell me where exactly I have to change pins, tks!

Issue solved. I made I mistake because I wanted to exchange FAN0 (instead of FAN1) with HEATER1. So I had to change D9 with D45. I modified the file pins/ramps/TRIGORILLA_14.h and only change LED_PIN to 9 and FAN_PIN TO 45.

The purpose of this change is to being able to use more current on the blower fan. I have an extra cable from the board to the hotend blower fan because I have installed a laser engraving of 2.5w that I connect to the blower fan connector. Previously, the blower fan used FAN0 port, but it only supports about 0.5A. My laser needed more than 1A, so that is why I have to use it with the HEATER1 (previously used by led strip).
