So you "homed everything" manually by pushing the extruder to the stops? They didn't move when pressed the home button?

Yes and yes, I tried pushing the Home button in the software and nothing happened (X and Y axis). I then moved the Y axis to the home position (at the end stop), and couldn't get it to move either direction. There is no sound or anything from the motors

Have you installed the stepper driver boards properly? In the right orientation?

Yes, the adjustment screw is facing away from the power connections as in the photo in the build guide

Found my mistake for the extruder temp warning missed a pin.


I think I have my bed level, and Z home set. My Y home pulls the bed inwards instead of outwards. My X axis though I have to tap the home button over and over to get it to the end stop on the left side. If I tell it to move 1 mm it may or may not. I think this may be a tuning problem with the stepper driver? Trying to understand that now.

Question for the folks who have this printer. What's the center to center distance between the two Z axis lead screws? I would like to use a closed loop belt and a center mounted single stepper on the top extrusion.

When I try to issue commands to my X axis I get:
13:12:02.440 : echo:endstops hit: X:0.04
Rechecking my wires. If I click home it moves a little left till it hits the endstop but I get nothing going right.

Jason, if you send M119 GCode, to get your endstop status, what does it report?

13:23:43.925 : Reporting endstop status
13:23:43.925 : x_min: open
13:23:43.925 : x_max: TRIGGERED
13:23:43.925 : y_min: open
13:23:43.925 : y_max: TRIGGERED
13:23:43.925 : z_min: open
13:23:43.925 : z_max: TRIGGERED

Why are your Max triggered? Do you see your problem? It won't move to the right if it thinks it's at it's max distance.

I have no clue. I did not know there was a max just a min ones. I've also checked wires. Tried adjusting the stepper driver. Replaced stepper driver with a spare. If I flip the wires for the X-axis then it moves opposite. I followed the directions on flashing the firmware from the Folger tech guide could I have gone wrong there I wonder?

If your board is properly wired, then you have two solutions in your configuration.h

1. Disable max endstops
#define DISABLE_MAX_ENDSTOPS
2. Change the max endstop logic.
const bool X_MAX_ENDSTOP_INVERTING = false; (change to opposite of what it is now. True or false.)

Edit: Sorry, used an older version of Marlin syntax. Fixed.

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool X_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
const bool Y_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
const bool Z_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
//#define DISABLE_MAX_ENDSTOPS

to:

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool X_ENDSTOPS_INVERTING = false; // set to true to invert the logic of the endstops.
const bool Y_ENDSTOPS_INVERTING = false; // set to true to invert the logic of the endstops.
const bool Z_ENDSTOPS_INVERTING = false; // set to true to invert the logic of the endstops.
//#define DISABLE_MAX_ENDSTOPS

Then use the IDE program to reload?

Or just remove the // from the disable max endstop line. The reload with the IDE.

My configuration.h (which is not from the latest version Marlin) says this, with the MAX lines commented out.

#ifdef ENDSTOPPULLUPS
// #define ENDSTOPPULLUP_XMAX
// #define ENDSTOPPULLUP_YMAX
// #define ENDSTOPPULLUP_ZMAX
#define ENDSTOPPULLUP_XMIN
#define ENDSTOPPULLUP_YMIN
#define ENDSTOPPULLUP_ZMIN
#endif

// The pullups are needed if you directly connect a mechanical endswitch between the signal and ground pins.
const bool X_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
const bool Y_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
const bool Z_ENDSTOPS_INVERTING = true; // set to true to invert the logic of the endstops.
//#define DISABLE_MAX_ENDSTOPS

So much closer!! Now I can move it left and right but my home button does not work!!. The Y and Z do the little bounce thing now and are working fine. My X end stop is on the left side opposite of the power supply.

My y and z are fine and working (ok maybe my Y is backwards but it homes) But the X does not home if I first manual put the extreuder head against the end stop then power the printer up hook to it connect it makes x 0.00 where ever the extruder is at when I hit home! it will move fine left and right but if I hit the home button then it makes that location 0.00 and will not move left of it. though my y and z home never changes when I hit the buttons they go home. An what are these errors in the log? I am using the file from google drive Folger links to could this be the cause of my problem?

Edited 2 time(s). Last edit at 07/26/2015 02:50PM by jasonsaffle13@gmail.com.

Ok, so I'm a few steps closer than earlier after a lot of troubleshooting and part replacement. I have my Y and Z axes working properly, but my X will not do much. If I push home, it moves a few mm and stops, then sets that position to 0. If I move it in the other direction, no matter if I command 1mm, 10mm, or 50mm, it moves the same few mm and stops. I can only move it each direction 1 time and then it stops working. If this a config issue?

Exact same issue i was fighting read above but still can not get x home to work

INteresting, wonder if there is an issue with the Folgertech firmware. This is my log when connection to the printer in Reptier. Lots of errors but I'm not sure what they mean. Also, the RAMPS test code runs fine, so I'm pretty sure FOlgertech has an error in the config, but I'm not sure how to troubleshoot that.

Try loading the latest firmware with the Folgertech settings already merged in - [www.github.com]

every problem I had was either electrical or mechanical .. I used the same stock software as everyone else,, everything works as its supposed I have printed out quite a few pieces and except for some ABS lifting They all came out just fine I am not a programmer so I left all the software alone ..

James,

Once again M119.

See what's triggered.

Press your Xhome switch and hold it do M119 and see what it reports. You may have to invert the logic for x min too.

I've thrown in the towel for now. I wrote Folger Tech and I am awaiting what they say. I did try printing once and the extruder moved to the front left edge of the bed and I did not extrude anything though I did have filament "leaking" out of the tip. Maybe it's something simple but to frustrated to see it right now.

Gonna drink some beers play some video games and look at it tomorrow. Came across this guy with same issue.

I will look in tomorrow. I think your close, but solve the problems one at a time.

I just added a reply in the comments for that video.

Jason, can I also suggest you read the first couple of paragraphs of [moosteria.blogspot.com]. It describes what I did to get it going. You have to have multiple things right - the physical connections, the firmware and the Repetier settings. If any one of them is wrong, or if they are not consistent with each other, then you can end up stick.

Hope this helps (and maybe wait until after the beer wears off before trying it )

See my blog at [moosteria.blogspot.com].

I can get it "working" by changing settings or pin plug-ins. But what I can not figure out is why when I hit Y or Z they home like they should but the X just marks where ever it is sitting as the new "home" location.

I've gone through the whole thread and I'm in exactly the same place as you. I just flashed the firmware linked a few posts ago and it does the same thing.

Mine never seems to respond to the manual controls in repetier correctly but it prints just fine.

Newbie with Folgertech 2020 i3.

I just got back from work and now im gonna config my printer, but the power supply wont ouput anything and the input it wired correctly i believe. The single circular prong is the earth ground correct, and the other two are interchangeable? I got it to work I had a cord mixed around. Now a new question what is the easiest way to make a belt tighter. The Y Belt is very loose now after I set everything to the home position.

I just went through tightening the Y belt the other day. The guides online say when it's tight enough, you should be able to pluck it and it'll sound like a cello bass string. No matter how hard I tried to get it tight by pulling on the belt, I couldn't get it tight enough. I ended up unscrewing the motor, installed and tied down the belt on the Y carriage holder at an eyeballed point where I knew it would be tighter than I could get it by hand (I marked off on the belt the tightest I could get it before), and then screwed the motor back on the frame rail. It's tight as a cello string now.

Okay thanks ill try that in the morning. Should my extruder fan be hooked up to the ramps board? The fan constantly running when the extruder is off is very annoying?
