Mini Kossel wont register endstops August 23, 2014 03:21PM |

Im finally getting around to setting up my Mini Kossel. I have everything assembled and wired up. I uploaded the standard delta marlin and when I go to home the axis', they keep trying to move up after they trigger the endstops.
I've tried changing home position. The endstops are wired NC -> top pin on RAMPS and C -> middle pin on RAMPS. Is that write?
I have also tested them with M119 and they all trigger/open fine.
I have also attached my config.h just in case.

Hi there,
I have been playing with Marlin deltabot recently and think I can help...
The Configuration.h file instructs you to copy the files from the example folder,
but when I tried to use this route, it did not work, those files look a bit outdated ...
When I look at your configuration.h it looks like the version from the example folder,
did you copy your Configuration.h file from the example_configurations/delta folder?
If so, try to use the default Configuration.h from the Marlin deltabot repository.
Hope this helps!

I just uploaded Johann's firmware from here. It says it hasn't been updated in about 6 months, so I am not sure how current it is.
It started off not homing correctly. It would jiggle the effector around a little bit and move down slightly, even though none of the endstops we anywhere near engaged (the carriages were about halfway down the printer). So I inverted the endstops in the Config.h file...
Now it homes... Kinda. It will go up to the endstops, hit them, then continue trying to go up for ~5 seconds. Then each axis stops one at a time. Here's a video of what is happening:

I use the same 'old' firmware version, it works!
Are your motors and endstops wired correctly?
- The X motor should activate the X endstop
- The Y motor should activate the Y endstop
- The Z motor should activate the Z endstop

This is a slight modification on Johann's firmware (modifications just for our mini kossel changes) which you can try:
[github.com]
It works well with our mini kossel kit

What does your M119 say exactly?
Mine says:
I need to find another input for the probe...

Mine says:
Reporting endstop status x_max: open y_max: open z_min: open z_max: open okFor my Minitronics board I had to swap the MIN and MAX pins in pins.h:
#define X_MIN_PIN -1 #define X_MAX_PIN 5 #define Y_MIN_PIN -1 #define Y_MAX_PIN 2 #define Z_MIN_PIN 6 #define Z_MAX_PIN 6Z_MIN_PIN is in conflict in my situation,

I tried uploading it but when I connected in Repetier, it did not register a firmware and would not send commands. Weird.
my M119 is reporting open status for all the end stops:
Quote
11:35:21.892 : Reporting endstop status
11:35:21.896 : x_max: open
11:35:21.896 : y_max: open
11:35:21.896 : z_min: open
11:35:21.896 : z_max: open
I just checked pins.h and it looked like the MAX pins for are set to -1 and the mins are set to a positive value. I switched the MIN pins to -1 and hte MAX to 2, 15, and 19 for X, Y, and X, respectively. I got those values from the RAMPS 1.4 wiki page so I am not 100% sure they correspond to the pins on my board.
Anyway, nothing worked and it still does the same thing when homing.

I tried flipping the wiring for the endstops on the RAMPS board, and still got the same result.

Check the pins.h in the think3dprint3d version for the correct endstop in numbers for RAMPS. Also if it wont connect then have you set the baud rate in Repetier to 115200?
The pins.h file matches the one I as using before (Johann's Marlin). Just changed the baud rate and got it to connect like normal, thanks for the tip!
However, when I home, the problem is even worse. With Johann's Marlin, the carriages will eventually stop after ~2-3 seconds. With the T3P3 version of Marlin, they just keep trying to go up and up.

It acts as if the endstops are not working.
When you run an M119. Manually trigger the endstops and see if they report triggered when you are holding it. And make sure that on the ramps, the endstops are in the correct location: the max enstops. From the left to the right, the endstops go x min, x max, y min, y max, z min, z max.

DOH! I had my endstops plugged into the MIN pins... stupid mistake. works now!
