Kossel display problem

I was gifted a not working Anycubic Kossel Plus printer. I turned it on and the display screen just shows rows of blank squares, and there is a red light lit on the mother board, and an occasional flashing green light. It has a RepRap Discount smart controller and a Trigorilla 1.1 mainboard. After many online searches I did the following, adjusting contrast, didn’t fix it. The fuse on the MB shows continuity, I tried the reset on both the MB and display with no change. I tried disabling the PS and running it from PC-USB power with no change. I tried reloading Marlin 1.1.9 firmware (I think successfully, but no way to tell) and still no change. Does anyone have any other suggestions? Is there any way to test the MB? I am a noob with electronics.

Are you able to communicate with the Trigorilla with something like Pronterface (send something like M115)?

I downloaded pronterface, but haven't used it yet, will try to figure it out tonight. Thanks for the reply.

Second the pronterface test. If that works, check the cables, including entirely swapping left cable and right cable to see if the symptoms remain the same.
A bad display can give those symptoms. I once replaced just the display (I had one on hand) to fix it, but you'll want a new smart controller.

I connected through Pronterface and sent M115 and got this result

I was unable to move axes with Pronterface. I also tried to heat the nozzle, it did not heat up , nor did the fans work. This is the readout when I connected.

does this look correct?

It says 4000 steps/mm on the Z. That doesn't sound like a delta to me. Are you sure you copied the correct configuration.h and configuration_adv.h files to the appropriate location before you built and uploaded the firmware?

That is entirely possible, I'll redo it and see what happens. What should it be?

After you extract Marlin zip file (https://github.com/MarlinFirmware/Marlin/archive/1.1.x.zip) you will have a directory called "Marlin-1.1.x".

Copy:
Marlin-1.1.x/Marlin/example_configurations/delta/Anycubic/Kossel/Configuration.h
Marlin-1.1.x/Marlin/example_configurations/delta/Anycubic/Kossel/Configuration_adv.h

To (replacing what's already there):
Marlin-1.1.x/Marlin/Configuration.h
Marlin-1.1.x/Marlin/Configuration_adv.h


This might be good enough to upload to the printer to verify the screen works. In either case you will need to go through this readme file to configure the firmware for the model printer you have.
[github.com]

You can verify that you got the configuration uploaded by viewing the output after you connect to the printer. In the author field it should say something like
@brandstaetter and/or @grbd

still not able to move axes

That config looks like a delta so I think you are on the right track. Before attempting to home the machine have you verified the endstops are triggering properly (M119)? With your latest build of the firmware do you still get the the "printer halted" error when you try to home the machine (G28)? A different error message? Have you been able to get any of the stepper motors to turn in any capacity?

I tried g28 and got the printer halted message, none of the steppers run, none of the fans run and the print head doesn't heat up. I have the heated bed disconnected, so haven't tried that.

Sent m119.

How is the board powered right now? For anything to run I'm guessing the power jumper will need to be in the DC position and the 5A and 11A terminals connected to the 12 VDC supply.

As for the endstops this doesn't seem to be your problem however I'm surprised only 1 is triggered. Did you go through all 3 endstops one by one and test them? ie hold press one down at a time see that they react properly with M119?

That could be it, I just have it powered through the usb, which is 5v right? I'll try the estops one by one. Thanks

Just hooked up the main power supply and moved the jumper and I have movement in the steppers. can't control it with Pface now. I don't have the 12 wall wort power supply. I moved the jumper back and I sent m119 y first then x then z

I'll have get a 12v power supply and then try the steppers through Pface, I do have the Kossel manual to configure it when I get the steppers moving

Why can't you connect to it with Pronterface? The USB cable should continue to work regardless of how the board is powered.

Just figured it out I had the wrong com port. When I did the estop test it looked like the previous stop would stay tripped, that doesn't seem right to me. What steps should I do first?

I was able to get get the print head to heat up and the fans working, although the temp ran over what I set

Hmm that is strange. I'd focus on one endstop at a time. It's likely a hardware problem so you could try checking these two things:

1) Check the endstop at the connector (that plugs into the Trigorilla) with a multimeter continuity test
2) Verify it's connected to the Trigorilla properly


Regarding your heatup problem, you'll need to autotune the PID for the hotend and bed. Make sure they are cold before you run these one at a time :
Hotend:
M303 E0 S200 C8
Bed:
M303 E-1 S60 C8

I found a lead off at the y endstop and its works fine now. I slowed the travel speed down and auto homed it and it went fine. I tried the auto bed level probe by pushing it while the print head was coming down from auto home and it did not stop. I'm going to check the wiring for that next. I will do the auto tune on the hot end and bed. Thanks for hanging in there, It would have taken me forever to get to this point.

I'm guessing the probe is not set properly yet. If you haven't already read this guide and set the probe type (https://github.com/MarlinFirmware/Configurations/blob/release-1.1.9/config/examples/delta/Anycubic/Kossel/README.md). The probe is either NO (normally open) or NC (normally closed), if that's setup wrong it could cause the head to crash into the bed. Using M119 to verify the probe is working properly is a good idea to avoid damaging to bed or the probe.

The probe, which is Z1 on my board doesn't show up after M119 only X,Y and Z. I assume it should. I checked the probe and it shows continuity (open?) when not touching and no continuity (closed?) when I push on it. I checked the 2 connectors at the probe and where the probe plugs into the MB between the Z and Y endstops and they are ok. I don't think I should try to calibrate until I get this sorted.

Sounds like the probe isn't enabled in Marlin. Did you go through that readme I linked? That tell you how to set up the probe. The setting is ANYCUBIC_PROBE_VERSION.

I did read it, but didn't quite get. I just reread and now I see. Thanks

I think I might have it sorted

Glad to hear it
