I am trying to use Repetier as the host software but I am experiencing a problem with it.
As soon as Repetier connects, the hot end switches on and heats up to a preset temp. I have not been able to disable this action within Repetier, even setting the temps off and setting machine as cnc router.
The machine will not accept any gcode commands from the manual control until the hot end is at temp.
Once hot end is at temp, I can send a homing command and the machine responds. I have then to have a hot end wired at all times to get over this connection hurdle.
With pronterface there is no problem and the machine moves fine with a cold hot end, indicating that the firmware is
not the cause.
Even a resistor or thermistor makes no difference, although once the machine has gone through the connection/hotend heat/ homing cycle, only then will it work without the hot end heating.
So any ideas how to over-ride or eliminate this requirement. Should I contact Repetier about this instead? I can see that a heated hot end will soften any ooze left over from a previous print and so allow the Z homing without screw jacking the bed to destruction!
My machine uses a Melzi board with Marlin firmware.
