Solved 'Beta' Original Robo 3D - Connected But No Control

Are you sure it is connected? You reading ambient temperatures for the hotend and heated bed?

Check the GCode terminal in MatterControl see if it has errors ... (scroll all the way back to the top to read it all)

 

Follow the link I posted above on the words "MatterControl" and open the GCode terminal and see what it says. Copy paste the entire log into notepad and then save it and attach it to this thread.

The main screen in MC is only giving you the online status, any errors will be in the GCode terminal.

 

Well, MC does not appear to be sending anything.
I'd try a different slicer/host program for starters.
There are no errors from the printer it is just not getting commanded to do much of anything.
I do not even see the commands for it to heat up the extruder/bed (M104 is heat extruder or M109 is heat and wait)
M140 is set bed temp and m190 is set bed temp and wait -- neither of those is in there so it is never going to print if it doesn't first heat the printer up ... at a minimum the extruder should be getting commanded to heat up

 

<-ok T:22.6 /210.0 B:0.0 /50.0 T0:22.6 /210.0 @:127 B@:0 [1.194]

OK, that looks as though it is heated.... nothing else is happening -- is it actually reflecting the temperatures correctly?
I would still suggest a different slicer as a test.

EDIT: My bad -- it is NOT heating which means it will not print.
This is the hotend being told to go to 210c and it is currently at 22.6 c (room temp)

T:22.6 /210.0

This is the bed being told to go to 50c and it is at 0 (which means the thermistor is faulty or bad connection, BUT that would likely not cause it to not print) It should be reading room temp (mid 20's C)

B:0.0 /50.0

 

You can experiment with it in the GCode terminal. Give it this command:

M140 S80

(use upper case just like that) type that in and hit enter.
Then see if the bed heats up.

You can also try:

M104 S185

same way -- type it in and hit enter (or SEND) and see if the hotend heat up

In both cases watch for any errors.

Not all R1 betas had heated beds so if yours does not just ignore the testing/temperatures for the bed and try the hotend.

 

Well, it is not responding to the commands to heat up that is for sure
Your picture on the right the last command is the host program telling it to heat the hotend and it is ignoring it.

Try a new USB cable (like new -- decent quality one). If that fails to help then I'd suggest reloading the firmware.
To make that work we will need a list of the mods (like the E3D) since some of them will have to be enabled in the firmware (like the E3D).

I suspect the USB cable... Unless there is some sort of other modification to the electronics/power supply or failed component it should be heating when it gets the M104 command.

 

OK, That plug needs to go somewhere
Can you trace it back to see where it is attached on the other end? Once we know that we can show you where it needs to land.
I can't tell from the cable/connector since Robo was not really very consistent over the years (and certainly not on the original one) with wires/colors/connectors. It looks like either one of the endstops or a thermistor. Either could cause your issues since if an endstop is unplugged the printer can't HOME and if it doesn't HOME all axis -- it will not print.

You can flip it on the side without problems just be careful when you do because if you don't pay attention the X crossbar/carriage can flop around and get loose from the screws that it sits on. An easy fix is you wrap masking tape or blue painters tape around the crossbar and one or both threaded rods. That keeps it in place while you turn it over and it is easy to remove when you are done.

 

If you can't figure out where that wire goes -- take a closeup picture of the RAMPS board (if you flip the printer over it is the top electronics board) and I can see which of them is missing a connector

 

There are two boards in the printer.
1) Arduino Mega 2560
2) RAMPS 1.4 shield on top of the Arduino

Installing the Arduino drivers should not cause an issue -- they must be installed for the printer to work correctly.
From what I can see of the wiring it looks OK.

 

If it runs under the bed it is probably the thermsitor for the bed and that would explain why your bed was reading "0" instead of Room temperature.

 

This will help show you where it should be landed if it is the thermistor for the bed

 

No, this is not a common issue

Something has come loose wiring wise Or some electronics have died... we can sort it out.

In some ways the bed thermistor is involved so fixing that (assuming it is disconnected) will help.
One of the first things most host programs/slicers do is command the printer to heat before it will try to print and if the thermistor is disconnected/dead then it will never get past first-base. It will be stuck in a loop waiting for the bed temperature to rise and it will not.

 

Ah yes, the old "power the arduino from the USB cable" trick
