Welcome to the SeeMeCNC Community

Hi budies,

I love droplit but i live in one country that's insane buy some outside, we pay around 70% of import taxes (tax over tax over shipping) and price gone to sky, its like paid 2,3x droplit price (printer price+shipping+60% import taxes+27% iva+9% IOF tax (its like if you paid outside with credit card my gov take more 9%), and my pocket don't have this size .

what i did, download droplit files in github, cut some parts, make some changes in Z structure, make some printable parts, include LM8uu and linear rods, put stepmotor in center, if work i'll publish here to seemecnc comunity.

1st question : one friend give me a protoneer GBRL+Uno+Pololu's drivers (cheap and nice) protoneer using end stop soldering in COM and NO, (signal and ground ) i see in your manual that u using COM (signal) and NC.

if i using COM and Ground i'll need make some configuration in firmware or will work ?

2nd question:

If i using linear rods and grow high print size i'll need made changes in firmware ?

Firmware changes its my fear, everytime when i see arduino code my soul frozen kkkkk .


If is possible help me i'll be happy and if no (no problem) i know thats this forum its for customers. i'll understand.

Cheers

COM is common. NC is normally closed, NO is normally open. For RepRap firmwares (and I'd assume GRBL since everything has derived from that in some way) there is a setting to invert logic of the end stops. If it's true then the end stops have COM and NO used, if it's false then COM and NC are used.

HI! Thx!!

I'm still fighting with the Protoneer GBRL, but I think the problem is to find where to place the NC (ground), the COM this easy Z + pin.

My 1st config EG: if i connect COM in Z+ and NC on other Z+ pin and pull endstop dont show nothing on UniversalGcodeSender

My 2nd: Same. if i pull end-stop dont show nothing in UnversalGcodeSender

Any idea ?

cheers!

Limit switch pins have been doubled up so that each axis has a “Top/+” and “Bottom/-“. This makes it easier to install two limit switches for each axis. (For use with a normally open switch)

their instructions are a bunch of jumbled hodge podge from each version. Your board doesn't have the jumper to configure the endstops. Looks like yours is always NO. I can't figure out what each pin of Z+ is, but I'd assume its probably a signal pin and a ground pin.

thx!!

If i pull microswitch, UniversalGcodesender need show some in console ? in marlin we have a command to see if is trigged or open, gbrl have same command ?

Cheers!
