Ramps 1.4, Repetier and Opto-end stops

(FYI - I've got a solid engineering background, but this is my first time using a Ramps board, so I might be making a newb mistake.)
I've gutted the electronics from a fried DaVinci printer and am replacing them with a Ramps 1.4 setup w/smart controller. I've hooked up the end stops and the servos and have begun testing them for functionality. Using the Ramps test code, I've confirmed the steppers are all functional. However, when I upload Repetier 0.92, the 12864 LCD works fine, and the menus appear functional, but I'm unable to control the steppers via the Position menu.

I think the big issue is that the Opto-end stops are not being read correctly. They are properly hooked up to X-, Y- and Z-, and I've confirmed (via DMM) that the signal is changing (5v High, .2V low) each time the beam is blocked or unblocked. Additionally, the end stops have LEDs showing their state, so I can see they are changing. Regardless of the voltage on the input pins, all ends stops show "ON" on the LCD.

Here is how I have them configured in configuration.h: (All default, except I switched the ENDSTOP_PULLUP values to false. Switching them back to true didn't help, either.)

// ################ Endstop configuration #####################

#define ENDSTOP_PULLUP_X_MIN false

#define ENDSTOP_X_BACK_ON_HOME 1
#define ENDSTOP_Y_BACK_ON_HOME 1
#define ENDSTOP_Z_BACK_ON_HOME 0
#define ALWAYS_CHECK_ENDSTOPS 1

What am I doing wrong? What can I check to fix this?

When I watch the serial monitor, the only issue I see is that it complains that I haven't hooked up the thermistors yet.

I'm using opto endstops with ramps and repetier, and at least with mine they need to be set as non-inverting:

#define ENDSTOP_PULLUP_X_MIN false
#define ENDSTOP_X_MIN_INVERTING false
#define MIN_HARDWARE_ENDSTOP_X true

However, if that was the only problem you'd still be able to see the values change when querying with m119, and it sounds like you're not getting that?

Precisely. The only other thing I've noticed is that they begin as "OFF", until I try to move the steppers, and then they immediately flip to ON, and stay ON until I do a reset.

Can you post a photo of the endstop connections on the ramps?

I'm using Marlin_Ramps_Epcos_i3v firmware and still having problems with my end stops and the rotation of my Z motors, I can only get the Z motors to rotate way and the end stops are not working at all. What setting need to be changed?

[Edit - ah, my bad - different people posting, I should read more carefully ]

I thought you were using Repetier - you swapped? It will probably be less confusing if you stick to one or the other until you have everything working, and Repetier has the benefit of the online config tool to make life easier.

the endstops.

Hi Yar, your endstops and wiring look fine, so we need to check what's configured in the firmware. Can you post the parts of the configuration.h that relate to the endstops and homing? If you test with m119 with and without holding each endstop down does anything change?

Sorry other than checking with Repetier-Host don't know how to check the m119 file. but here's what you ask for. (I hope.)

Is the Z endstop different to the others? You have the pull-up for z-min commented out.

You can use repetier-host to send m119 to query the end stop status. In manual control, when connected to the printer type m119 into the g-code text entry box and press send. The result should show up in the console. Check what the status is with none of the endstops triggered, then hold each one down in turn and send m119 each time. Make sure that the status for the expected end stop changes.

Ok did the test and here is what I got... its greek to me, can you make heads or tails out of it? I wish I would have gotten a plug and play 3d printer....

OK, that's progress. The first time you ran m119 the printer reported that the Z min endstop was activated - were you expecting that? And the second time the Z min wasn't activated, again did that match what was happening at the printer? If not, it may be because the pull-up for Z min was commented out in the config file. With a micro switch end stop, if you don't have the pull-up configured the input can change more or less at random which will give very confusing results. So, if the Z endstop seems to be behaving randomly, take out the // at the beginning of this line in the configuration.h

//#define ENDSTOPPULLUP_ZMIN

ok did the test again took out the //. now nothing is working.

Ok, so we should just focus on the Z endstop and work out what is going on with that.

First off, is it a micro switch like the others?

You removed the two '/' characters from in front of the //#define ENDSTOPPULLUP_ZMIN so that it now looks like

#define ENDSTOPPULLUP_ZMIN

and then you recompiled and uploaded the new firmware to the mega2560?

In the log you showed above the z_min shows triggered 3 times and open once, but I can't tell what you were pressing at each test. So if you do a series of m119 tests with the Z pressed then not pressed, how does that come out?

Do you have a spare switch that we could temporarily connect to the endstop pins? That would allow us to rule out a broken wire or bad connection?

let me ask you a question, if it jump across the switch should I get a reading then the switch is up or pressed down? I have one new switch when I read between the post (say) pos and neg, when I press down on the switch it OPEN tel off it's CLOSED is that right?

Hi Yar,

It depends which pins you connect to on the micro-switch. There are three pins, one is common (i.e. you should always connect to that one), normally marked with a 'C' or 'COM'. The other two, one is "normally open" (NO), so if you connect to that marlin will say it's open when the switch is not touched, and triggerred when you press the switch. The other connection is "normally closed", so if you connect to that one marlin will say it is triggered when it isn't pressed, and open when it is pressed. It doesn't really matter which way you connect it up as you can change the firmware to match by setting the *_ENDSTOPS_INVERTING values in configuration.h. What matters is that it always behaves the same way every time you send m119 with the switch in the same position.

okay this is the last test just worked over all the the switch's. m119 test

I would like to know does this temp look right?

That looks pretty high for in around there. I'm not a fan of bringing the +V for the heater bed through the RAMPS board. It's only done to route it through the poly fuse and I don't think it's worth it for the amount of heat generated. I ran +V straight from the power supply via an inline fuse to the bed which dramatically cuts down on the heat build up in the RAMPS. The circuit is switched on the ground side, so that current still passes through the mosfet and the board, but the traces are bigger and the ground connections are commoned, so the current leaves via more connectors and wires.

Temperature wise, you don't really want to see anything above 50 to 60C on the circuit board. Add a heatsink to the heatbed mosfet and provide fan cooling if necessary.

What setting do I use for the heat bed, I have a 270 x 200, it was mendel prusai3 printer. I have tried 3 or 4 and nothing works, tell it to heat it gets to 39.6c and then starts to cool down again, exturder works fine.

thank you.

Type 1 should be a reasonable enough choice to get things working, assuming you have a fairly normal 100k NTC thermistor. Was that 39C reported by the printer or measured some other way?

Can you post a photo of the endstop connections on the ramps?

I am attaching them as follows to the ramps board:



I've gone through all the connections with my multimeter to prove to myself that:

• The wiring harnesses are, in fact, connected as above.
• The signal, in fact, switches from .7V to 4.6V when the beam is blocked.
• The same opto-endstops read correctly when tested on an UNO.
• There are no faults in my RAMPS board and the signal pin does, in fact, go to the appropriate pin on my MEGA
• The same problem happens with Merlin firmware, so this isn't a Repetier bug.

What else can I check?

EDIT: Fixed photo links

I had a break through last night. I had been using the LCD (a generic Lcd12864 smart controller to determine if the endstops were on or off. I re-read this thread and noticed this:

see the values change when querying with m119

I hooked the mega up to Repetier Host via USB, and discovered that M119 IS giving the correct values.

The problem still remains, that the LCD and the LCD commands are not behaving as expected. I will do more troubleshooting soon to see if any other symptoms go away or change when using repetier host vs the LCD commands.
