Heated bed in CNC MODE
the question is how: i can use my 3D printer (repetier firmware 1.0.0 dev - repetier host 1.6.2) in cnc mode (M453) without the heated bed connected? Repetier host give me a fatal error (heater/sensor failure), it would be possible to simulate a fake temp sensor in CNC or LASER MODE ?
you can just mount a dummy resistor (i use a 100kOhm) for simulating a bed temperature sensor.
(also for simulating Extruders).
@Repetier : wouldn´t it make sense to disable the sensor check in CNC and Laser mode
and for example Show coords including G92 Offset instead of temperatures?
The problem is the same with the extruder thermistor, when i mill the printer head is not connected.
in extruder.cpp (should be line 351)
search for :
and replace that by :
if (Printer::mode == PRINTER_MODE_FFF)
Printer::mode = PRINTER_MODE_CNC;
Com::printFLN(PSTR("Changed to CNC Mode"));
for me that works ;-)
may be you can implement that as a preliminary solution , automatic switch over to CNC mode is necessary because
it´s not possible to change mode via Repetier Host
"Only problem I see if you enable while bed is removed it would start in FFF mode and trigger the error.There your trick will work good, but with bed mounted and a real error your fix will prevent the failure. "
that´s correct but nobody will use heated bed or extruders in CNC or laser mode and also if you go back to FFF it will trigger the
As you know when its started in FFF and error is triggered you cannot change mode by Host, that´s the problem for universal machines.
checking temperatures/thermistors in laser or cnc should not trigger a fatal error
