Right now I have a 10k resistor between ground the signal, and another one inline with the output pin.
I don't mind getting a different probe if it would be easier to work with. Can you recommend something? Or I should just get the NPN version of the same probe.
Thanks,

Hey gang.
I have an induction sensor (LJ12A3-4-Z/BY, same one used by Printrbot) and voltage divider resistors. I'm feeding it 12v.
When the output pin is not connected to the RAMPS, I measure 0v when the sensor is in the air, and 5v when it's touching metal. However, the Z-Min endstop status is always OPEN or TRIGGERED (depending if I invert the logic in the firmware) and doesn't change state

I don't even have words to describe the audacity of wanting $5000 and above for a pretty standard printer.

Hi all.
Is anyone using an LCD with Marlin?
I uncommented "#define ULTRA_LCD " but now it doesn't compile:
ultralcd.cpp:22: error: 'MANUAL_FEEDRATE' was not declared
ultralcd.cpp:919: error: 'SHIFT_CLK' was not declared
and many more...
I'm using the latest build from github.com/ErikZalm/Marlin
Thanks

Firmware - mainstream and related support
So, which extruder + hot head are you using, and why is it good / bad ?
Here are the ones I know about:
J-Head hotend, which seem expensive (worth it ?)
qu-bd
Cheap !
Another hotend, even more expensive:
And the default PG35L extruder that seems to be everywhere.
Did I miss something ?

Thanks for the awesome reply, Thinkyhead !
This actually helped me a lot.
Care to upload some pictures of prints you made ?

Where did you buy the metal parts and how much did it end up costing ?
Did you print the plastic parts or buy them ?
Are you happy with it ?
How is the Z-axis resolution ? (I have worries about threaded rods...)
Anyone willing to help me out and print the parts needed for the wood box version,
I would be super grateful (I'm in Ontario).
Thanks.

Thanks for the detailed response
Can you explain why RAMPS , and how are they easier to setup ?
Thanks.

I have decided to build a Kossel,
which board do you think would be suited ?
Also, it's not clear to me how do you program the board with the specific dimensions/calibration
of your printer ?
Thanks,
HP

In your opinion, what would be the easier printer to build from scratch ?
With parts cost not more than 400$.
I was thinking about a Kossel, or a Mendel90.
What do you think ?
Best,
HP

Is there a finalized delta printer ?

I want to built my first printer, a delta Kossel.
I live in South-Western Ontario, Canada.
Can someone please print me the parts needed ?
Thanks !
