end stops

jstoy · Post by **jstoy** » Mon Apr 27, 2015 8:39 am

I have a Geeetech I3 Pro printer with the 1.4 ramps board. Not sure why, but my end stop for my z motors seems to be reversed. I have to manually push down on the end stop so the motor will go up. The end stop has no effect when the motors are going down towards the glass. Has anybody else had this problem? If so were you able to correct it? I have looked at the end stop wiring several times and I believe what I have is correct. I am using the firmware which came with my printer which I received last week.

Thanks in advance

Jerry

Maybe it's firmware issue, please check your email.

I took the I3_Ramps_ino.zip which you sent me and built the firmware and uploaded to my printer. The message on the LCD display changed slightly as a result of the upload. The first attachment shows the new screen (img_0218.jpg).

The second photo shows what occurs when I tell the printer to move down (Z direction) (img_0217.jpg).

The new firmware helped in some regards. I no longer need to hold down the end stop for the printer to go up. The printer appears to be working properly in the up direction.

I am seeing similiar behavior in the x and y axises. The printer moves properly in one direction, when going in the reverse direction a message appears on the lcd panel that the end stop has been hit.

Please let me know how you would like to proceed.

Thanks

Jerry

How did you connect the endstop? Is it like this? From left to right is x, y ,z.

I have the exact same problem, have you been able to solve it?

Can you send me the file I3_Ramps_ino.zip file
And where is this configuration.h file at as I can't find it either in the folders for Arduino . .
Only configuration.h is in Marlin folder and for Marlin !

Your endstop direction is wrong, change the corresponding directions here in configuration.h and upload your firmware to check it:

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool X_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Y_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Z_MIN_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool X_MAX_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Y_MAX_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.
const bool Z_MAX_ENDSTOP_INVERTING = false; // set to true to invert the logic of the endstop.

what's your printer type? I'll send it to you.

I have a Geetech i3 Pro C Dual Head 3 D Printer
I also have 3 programs which talk to the printer via /dev/ttyUSB0 and only go one way to the home spot !
Repsnapper, Reptetier-Host, and Mattercontrol ! . . Also I Have the Arduino IDE installed . .

I think it's the endstop problem, I test it in my I3 X and get the same result, change the direction and see if it works.
