Solved ALL axes homing centers off after E3D v6 install

Hi Robo 3D community. I just recently installed the E3D v6 hotend to my robo 3D R1+ And everything works as should.. except for the home positions for all 3 axes.
The Z-axis is stuck about 5in above the build plate.

The Y-axis is off by a couple inches

The X-axis is by far the worst where it thinks it is all the way left at the center of the build plate. This leads to a horrible grinding from the belt slipping when it tries to go outside the build plate to the right.
The 9 point calibration does not work correctly, I have checked my z limit switches which are fine, and I have made sure the build area is correct in mattercontrol 2.0. The problem persists. Is there a way to zero all of the home positions? Any insight is appreciated.

 

I've run into a similar problem with my R1 plus in the past. I can't answer the x/y problem but you may be able to resolve the z trouble.

Consider to power off the printer and manually drop the z-carriage by twisting the drive screws. Bring both to the bed, perhaps a millimeter or two above, then drop each side until you hear the click of the microswitch. The idea is to get the click to match the same amount of movement for each side.

Leave the carriage in the "down-click" position when you power up. The machine should be able to recognize that it's at z-zero and re-calibrate the z-position from there.

Check your microswitches for the other axes to ensure they are registering properly.

 

It seems as so all of the limit switches are working. At least the Z and Y, though their home positions are significantly off. The X-axis is odd though because when I run the homing command in mattercontrol, the X-axis moves right, instead of left where the home position used to be.

Is there also an x limit switch on the right side? I cannot notice one.

 

Check the electrical cable tension & movement going to the hot end & carriage. I've had this issue a number of times, and it was hard to analyze since everything looks fine. The cable sometimes pulls on the carriage which prevents the Z switches from working correctly. The cable under the bed sometimes bunches up, and causes issues as well. I had to grind down the center of the plastic between the rails under the bed to allow more room for the heating bed's cable to pass through without getting caught.

 

So, I have not installed any differing firmware than what was stock. I have checked wiring on all of the switches and it is all correct. I based it off of this image.

All Z-axis switches are in place. I am at a pretty big loss as to what is going on.
Some tests I did run include swapping the polarity of the limit switch wires, as well as messing with settings in matter control 2.0 to try and bring it back to the original home position.
Oddly when I click home on mattercontrol the control brings it to the center of the build plate in the x & y axes, and it rests about 4 inches above the build plate in the z. It thinks that x-zero is at the center of the build plate and does not allow me to bring the extruder to the left towards the limit switch. When I try to print a file the control brings it beyond the build plate to the right in the x-axis, and keeps raising it higher in the z.
Is there possible firmware updates that may be able to fix this? Could it be switching to a newer version of mattercontrol is culprit?My printer is pretty useless at this point..

 

This happened to my printer on a few occasions. The z axis end stop switches had to be adjusted. A few other times, the cable going into the hot end pulled away from the regular position on the hanger on the top of the case, and it had to be adjusted.

 

@mark tomlinson This is the endstop status.

"M119
x_min: TRIGGERED
y_min: open
z_min: TRIGGERED
M105...."

At this time the extruder sits at the center of the build plate about 6 inches above. The x and z limit switches are not being physically pressed. So these are normally closed switches? When they are not physically being pressed should the code report triggered or open?

Also, regarding mattercontrol what other splicer softwares are compatible with the R1+? On robos website they say that cura is for the R2 and other models only, and the only splicer software listed for the R1+ is mattercontrol. I have downloaded cura recently and tried messing with it, but it gives me the same problems as I am having using mattercontrol.

 

So, I seem to have fixed the problem and I am very confused but elated. I was doing exactly what you just said, manually pressing the x limit switch and running the M119 command to see the report. Well when I would press the x limit switch, the z limit switch would chane status. I checked the wires, and the correct wires are run to the correct pins at least based off of the image above (x-limit to x pins z-limit to z pins etc..), but I switched them just in case. Sure enough the printer begins homing correctly and I have no idea why but the x & z limit switch pins are happy swapped.. Ill take it. Thanks for the help @mark tomlinson.

 

@mark tomlinson Do you have a list of all G & M codes used for R1+ with Marlin firmware?

Also, I am now looking to install the LCD screen I have had for months waiting on a working printer, Do you know of any resources to installing and making the firmware compatible with the screen?

 

Which screen do you have? You have to edit the firmware to enable Marlin to recognize it. Each screen has a library which has to be installed. Some common screens already have the library installed.
