Just a note, there is a reason for temp settings in the cart. Due to the way the head is constructed on this printer, temps over 245 for extended periods can damage this head.

Yes, I'd figure that higher temps for extended periods is not good.
Anyway, I rezapped my cartridge to 245/100@400m.

I see that the printer ramped up to 245/100, but came down to 240/100 for 1st layer. It then came down to the expected 225/85 at 2nd layer.
So, no "liberating" just yet.
I'll jump into it, head first, when I return from my ship next month (leaving in 3 days, so I don't want to "brick" it just before leaving)

So, I've rezapped my cartridge to 245C, 100C, 400m. Doing a print now and I'll see how it turns out.
I set the gcode file to 235/100 on first layer, reducing to 225/85 for the rest.

I am just one hair away from upgrading to Repetier and Host, though I've been a little reluctant so far..

Anyway, since the OpenXYZ seems to work fine and I'm using Slic3r to properly render my prints, and the FW 1.1.E works without counting down filament, I have not yet upgraded or liberated my Davinci (yet).

But, I have just zapped my cartridge up to 400m, 250C, 110C in order to have a little flexibility in my temperature control. (Before it was zapped to 240m, 230C, 90C).
However, this did not work so well.

My extruder ramps up to 250C, and bed to 110C regardless of what I put in the gcode-file.
Is this common failure of the XYZ-cartridge-mockup?

As a side question, when I upgrade to Repetier, I understand that I do not need any (zapped) cartridge in the printer, and I do get full an total control of the temperatures?
And one last question; I've checked numerous YT-vids and tuts on RepetierHost. Is it possible, and in case, how, do I send the print to the SD-card before printing?
(My PC tends to do some funny stuff every now and then, and I don't need to have a 13-hr print broken by my 4m USB-connection)

The davinci with stock firmware will always go to whatever the cartridge says first, then it will check to see whatever is in the gcode. When I was on the open mod, I did not use a resetter, and as such the printer would go to normal temperatures (90/210) then move a bit, then pause to wait for the temperature I listed in my slicer.

With Repetier, the printer couldn't care less about the module to read the cartriges- it doesn't know how to use it because its not in that firmware.

Yes you get full control, it is like any other DIY printer running Marlin.

You can move your files to the SD card and print from there.

Yes, with repetier you don't need to touch your cartridge again. You set the temperatures through the slicing software and you can adjust the temperatures while the machine is printing from repraphost or similar if you wish.
