Hello All,

I just put together my first 3d Printer. A Micromake delta 3d printer with the linear slide rails and a heated bed.

I copied the Configuration.h file from the Micromake thread and its attached.

Every time I home the printer two of the towers home fine (X and Z) and then one (X) just skips on the stepper when it gets to the top. Because of this I really can't move onto any of the next steps like bed leveling or even do a test print since it doesn't know where the bed is.

Can you please help???...

Some notes:
Regular ol' mechanical endstops
Using Repeater Host on a Mac
I've used "M119"s to verify that the board sees the stops being switched (when they're not pressed the feedback says L and when they are pressed they say H)

It says this right now - (with all three towers maxed out)
< 10:47:25 PM: x_max:H y_max:H z_max:H
- but when it homed the x kept trying and trying to go higher.

Thanks for the help!! I'm dying to get this thing going!

You should start with checking endstop-status using M119 G-Code. - Maybe one of your Switches is wired wrong, defective, or configured wrong (sorry your configuration.h is missing line breaks - so it is nearly impossible to read) - Take Special care, if you might have max and min endstops mixed up!

Thanks Sir Death,

I should have double checked the attachment. My bad.

So I spent a lot more time with M119s and I found out that I did have one endstop a smidge higher than the other two, but it was clicking. Adjusting it made me accidentally come on an odd scenario. When I adjusted the end stop that was given me a hard time and then homed another axis ran into the same issues. (Mash the endstop and keep going and going), but this one had been working fine every other time, but this got me to thinking if it was just an issue of timing. I did an extra couple M119s to confirm that all the towers endstops were in fact still working. I turned off power to the steppers and manually/physically adjusted the extruder such that when homing the each endstop would hit at a different time, first one then the other then the last. and OMG!! it finally stopped. It homed correctly!! I can't believe I hadn't run into this scenario before, but still.

Is there a setting that I have wrong or is there a way to home in a way that basically does one tower at a time??

Here's the segment of my configuration.h

Thanks all for your help. I feel like I'm so close to getting going.

Nothing looks particularly out of place in the configuration.h to me.

But I'm wondering if there was either a typo in your first description, or else if that's the problem. You said:

Every time I home the printer two of the towers home fine (X and Z) and then one (X) just skips on the stepper when it gets to the top.

So did you mean to put a "Y" in there anywhere, or is it the X and Z that home, with the X then starting up again?

If the latter, I wonder if your Y axis motor pins are mis-defined, so that it runs the X axis instead of the Y.

Maybe check your pins.h and see if both X and Y are defined to the same pins?

Thanks Maso, You're right, it was a typo. The Y was reading correctly. What I think was happening was that my carriage wasn't hitting my endstop switch reliably, but my finger was. So using the M119s showed correct functionality it was my carriage not adjusting correctly. I finally understood to adjust the endstop so the carriage hits it better and now it's finally working.

Thanks all for the help. and... I'm a dummy!! Haha.
