Multiple Extruders on second MCU causes error: MCU 'eux' shutdown: Rescheduled timer in the past #1134

Closed drphil3d closed 5 years ago

drphil3d commented 5 years ago

I'm using two boards one for motion einsy rambo and a second board printrboard RevF for extruders, I can't seem to make it past purging the first color, as soon as it moves to print I hear a squeak and it gives this error.

I've had no issue printing with a single extruder but as soon as I try to use more then one it freaks out.

I'm switching between extruders using the command T0 and T1. I've tried adjusting the print speed and gone through all the gcode to make sure there is nothing out of the ordinary.

Do I need to activate and deactivate each extruder? I am able to switch between extruders by activating the next one but do I need to deactivate the previous one for it to work correctly? I'm using the same gcode to activate and deactivate.. maybe that's causing issues.

the log file doesn't seem to have the latest version of my config file in it which is strange.

This file contains common pin mappings for Einsy Rambo boards. To use

this config, the firmware should be compiled for the AVR atmega2560.

See the example.cfg file for a description of available parameters.

I'm trying to decrease the current on the stepper drivers of the printrboard RevF but I don't know what this scale value relates to. I turned it down but my motors are still getting super hot under load.

The attached log file does not contain the "rescheduled timer in the past" error. We would need that log file in order to assist. Beyond that, in general, that error is the result of trying to step at a rate faster than the micro-controller is capable of.
