Since I'm going to drive a hot wire for my foam cutter, I thought it might be quite neat if I could control the hot wire via smoothie.
It is probably not very feasible to temperature control the wire reliably. (Will see I will do some tests with that. But I don't think it's viable)
But temperature control doesn't need to be super precise. Ideally I could just set the current for the wire. That is why I got quite excited about the currentcontrol feature. But it is not quite clear to me what current it controls. The G-Code M907 accepts values for X Y Z E. I suppose those are for the stepper channels.
I would of course need that at one of the big mosfet heater outputs.
Alternatively, is there perhaps a PWM mode for the big mosfets? I see no gcodes for that or any other references.
