that will prints and calibration im possible.

thx

That may be referring to the FelixBuilder dual head calibration, which assumes PLA temperatures.

Thanks Kerog, yes it is. I suppose I could manually edit the settings for another type of filament. The problem is I had planned to pretty much only print nylon on my Pro 1. Do you have a Pro 1? If so, how is it working out. I am still waiting on mine.

Can anyone tell me how the auto calibration on the Pro 1 works (I don't have my Pro 1 yet). Does it use a mechanical or conductive method to sense the bed? I intend to print nylon and I am finding that Garolite is recommended as a bed material. I do not know if this will work with the auto-calibration if I stick this on top of the aluminum bed.

Thanks, Dhatw.

Got my PRO 1 yesterday. Just had enough time to open assemble an admire. Very well put together. I am hoping I don't have to work this weekend so I can give it a try.

First print on my Pro 1. Went well. Orbi-Tech Smart ABS.

It's a pressure sensor. The extruders are mounted on flexures that double as handles to pull out and snap in. When the tip makes contact with the bed, it deflects the flexure, changing a voltage and tripping the Z stop. So bed material is irrelevant. However, it does mean that the autolevel (and regular Z home) has to be done while the nozzle is hot, so that what is being detected is the nozzle itself, not a glob of filament on the end. This also means a dab of melted filament may be deposited at each point where the autoleveling is done. Once the three measurements are made, motors adjust the two right-hand points of the bed support triangle to achieve the correct level. So it's a physical auto-leveling of the bed itself, as opposed to the Printrbot autolevel which uses an inductive probe and then adjusts the nozzle Z height as a function of X and Y to compensate.

The Z home process heats up the tip to a set temp (150C) and then does the actual home command. Don't know if Nylon is sufficiently soft at 150C; if not, you might have to make a firmware adjustment to change the 150C set point to something higher.

All of the above info is based on using a prototype Pro 1.

That's awesome Keith, thank you. Good point about the nylon temperature, I'm about to make a test print with Taulman Alloy 910 and that may be an issue. I will pre heat the hot end and turn it back up if it let's me when the auto levelling routine starts.

My first dual head print (ever).

I wrote down some of my experience with the Felix Pro 1. Unfortunately, so far, I did not find time for printing some benchmark pieces.

http://edutechwiki.unige.ch/en/Felix_Pro_1_3D_printer

Of interest (you decide): Ease of use (including self-calibration), reliability of longer prints, objects with a large flat bottom, things to improve in Felix Builder, support of "limp" TPE...

- cheers ! Daniel
