A couple of weeks ago little Stephanie asked me if I could print out a skull (of all things she could have picked...), and I said sure, here we go!
The first thing was that the moment that I turned on the heaters, the printer died. After fiddling with it a bit I got it going, but then the extruder clogged up, and we got nothing.
So I lurked around here, and decided to replace it with a Prometheus hot end with the Trick Laser mounting plates. Sweet!
I downloaded the SeeMeCNC version of the firmware (0.92.2), set my printer to "2" (I have a Max V2), configured it to used the different thermistor that comes with the Prometheus, built it, uploaded it to the controller, and now the head won't go all of the way down so I can set my Z axis.
I checked the forum here, and several others, but I haven't found a fix yet.
Here are my .h changes:
Code: Select all
#define PRINTER [color=#0080FF]2[/color] (was 5, but I have a V2)
#define MIN_DEFECT_TEMPERATURE [color=#0080FF]10[/color] (it was too chilly to get the printer to heat up)
#define EXT0_TEMPSENSOR_TYPE [color=#0080FF]8[/color] (was 97, but the Prometheus uses a different thermistor)
Code: Select all
// 1 = ATX on older machines 2 = Rail style PSU on newer machines ############################
#define POWER_SUPPLY 2

So now some details on the specific problem.
The printer was "banging" when it was sent to home until I sent it home from the Rambo controller. Then it smoothed out and has been working fine since. Still scratching my head about that one.
The main problem, is that once homed, the Z axis is set to +250mm, and I can drive it down to -100mm but no further. I tried changing the:
Code: Select all
#define Z_MAX_LENGTH 350
I'm using MatterControl, but I have tried Repetier and Cura as well.
Thanks guys!
