Trouble after updating new version and new firmware

Hello everyone,

Here I m facing new problem with Robo3d printer after updating new version of Mattercontrol a new firmware is also showing to be updated and I updated that and then after problem was started.

1. When I start printing in default setting from home position, extruder Nozzle goes in center to start print but after a sec it stop and I see temp goes to 40, 23, 60 anything suddenly. And I tried so many times but stop at same position.

2. And difficult to connect also I have to unplugged and try then it connected. But problem is same as above.

3. And sometimes print bed not get heated up. I have to disconnect close and connect then it works once in 5 times try.

Firmware is not reverting back and showing new update available after updating. I am using Mac OSX.

Hi, Mike thanks for reply. After updating the Mention firmware nothing happen positive, only the Z up axis of a nozzle increases but it moves to center and stop there only. And Temp its showing zero degree.

 

Do you have the new auto-leveling z axis or the old screw style?

The temp at 0 means you have an open circuit in your thermistor line, or it's come unplugged.

 

I have a old screw style. And don't have any idea about thermistor line. Earlier it was working fine and the neutral temp is between 30-33.

 

Ah ok, you need to use the 3-14 firmware then: http://forums.robo3dprinter.com/index.php?threads/marlin-firmware-update-3-14-14.1857/

See if that fixes it.

 

After updating, position of a nozzle got corrected but temp is the same 0 deg.

 

0 means an open circuit. It can't mean anything else. Find the open circuit

 

what i have to do in open circuit it is in the below part of the printer.

 

Turn the printer on it's side and find the break. If it's at the molex connector you need to contact team robo for a replacement. Otherwise just solder/crimp the wire back together

 

Temp problem solved after uninstalling completely and power off then On with usb unplugging and plugging. But still not able to use properly it stopped at in center of the bed during printing.

 

Properly home it? Is one of your z switches deactivated?

 

The problem is with loose thermistor wiring in Hot end that i have solved. But my next problem is Heated Bed thermistor you can see it in image the red glue is teared or not touching the plate properly, but when i pressed it shows temp increase in software and default temp it shows without pressing is between 31-32 deg. So what should i have to do now. please suggest.

 

you could put a piece of kapton tape over it to secure it down further

 

I have done the same after removing red glue and now it's working fine. Thanks a lot.
