Go to this link: http://www.geneb.org/rostock-max/Rostoc ... -Guide.pdf
geneb does a great job with assembly of this printer.

There are three leads, it's the outer two.

thanks you guys one less thing to touch up smile

just so i get this right the end stops are for setting zero point?

[JohnStack]

Yes! Each time G28 is issued, each of the arms raise up to trigger the switch. This is the absolute measurement on each axis to the bed. The RAMBO firmware stores that and uses that as the base for arm movement.

BTW, they are not polar - so just wire them. The switch is only closing a circuit.

ok so i got the end stops set at the edge of my glass and down to as close to the glass as needed or is it the other way around as far way as it can. since iam not doing the rostook max printer doing a lotof converting of info lol post some pic of what i did see if i got this ass back words

Remember guys, Spart is building a cartesian printer, not a rostock delta. Endstop wiring may be different from geneb's manual.

Our rostock endstops are certainly not near the print bed like yours spart.

[spart]

yup i got to keep my eyes open wide doing this stuff learn as ya go destroy on the run lol

[JohnStack]

How would a simple switch that closes kill anything?

[ApacheXMD]

It can if youre relying on it to stop the head from crashing through the glass bed.
I'm just saying that spart might want to consult other sources too for endstop wiring help. I know seemecnc also has the H1 cartesians but the forums is starting to get rostock-heavy.

And our rostock switches are wired NC, normally closed
So hitting the switches will actually open the circuit.

Sorry Spart!

DM me with your Paypal account. The least I can do is buy you replacement stock. My bad!!!

i got it all done, if it don't work back to the drawing board lol, going to do some more looking around saw a couple guys on you tube wiring it the same way, but for as in close to the glass i will set it up high till i see what it dose for stopping space set it from there i set it up on a adjustable stick idea so got room to move. this is more like a mandle printer i think that's the model so many out there will run into something

this is what i have done hoping this is right lol http://www.youtube.com/watch?v=TKWxembgLw4
