Unresolved Hardware error

Hi Harry , got a message today from my RoBo 3 , ,,, Printer hardware error , your printer is reporting a hardware error , this may prevent your printer from functioning properly ,
Error reported " EXTRUDER SWITCHED OFF MAX TEMP TRIGGERED "
That what happened , any ideas ?.? Thanks in advance

 

Hi Geof , It said at the beginning to ask Harry , I don't know I'm new at this , , Thanks for your reply , I was looking over the connection and found the wire had pushed out if clip end I pushed in and got it to stay I'm pretty sure , but on the extruder temp it says 375 degrees but it's cold , I also tried to preheat the bed but it would not , any way to test the thermistor ?? What about the ceramic heater THATS the wire I found pushed out , your help is appreciated, Thanks

 

Well Thanks for the welcome , I'm new to these machines , so I'll be looking for help , I took the extruder out it was pretty mucked up , , got a lot of filament off , , removed the ceramic heater , but not sure if the thermistor could even come out ??? Still mucked up around that area but not all that bad , cleaned it up reattach the wires , that's when I found the wire had pushed out of connector of ceramic heater , Pretty sure I got that , fixed , I have a meter but not sure how to use , can you tell me what to set it at , so on , I'm not with printer right now so I'll try to do pictures tomorrow, ,, a couple of other questions , on the ramps board can you use a plus series board or does it have to be an original board ?? The ceramic heater ?? What size is it ?! 30 or 40 , watts 12v or 24v , ?? The the thermistor, do they come out of the heat head usually ?. Where can one get a complete run down on all the workings , part names , wire diagram, ? Just wantvto know what's whatvon these things , a lot I know but if I see a manual or other things I can usually figure things out , Thanks for your help

 

Good question ?? It appears to be an R1 ?? How do you tell for sure , I purchased it used knowing it had a problem , but I like to solve these problems , I have a RoBo R1+ , that had has a problem with the ceramic heater , I ran out of line and it jammed, so I figured out how to fix that but when I reinstalled the extruder I did not get the wire tight and it hung up and pulled one wire out , so I'm waiting on a replacement, heater , I hope that all it needs , anyway how do you know what model you have , and how do I send a picture on this forum, Thanks

 

Not sure I'm doing this reply right but here goes , Hi Mark , im guess it's an R1 not the plus , it has couplers That the threaded rods go in , Strange the threaded rods do go up into holders in the cover ?? I thought that was a plus model, the plate does not have the cable coming out the back , the thermistor is not removeable from the extruder as on the plus , Id post a few pictures if I new how to add them , I'm using an iPad and have the pics but do not see a way to download them to this conversation, any where any one know where to add them ?

 

If you want, you can also upload images to imgur.com without an account. I have yet to create one and can do this from my PC or mobile device.

 

Thanks Waldo & danzca6 , I'll give that a try , and let you know if I'm able to figure it out ,

 

Not. Sure if I'm doing the reply right , but I'll try that and let you know if I make out , Thanks Waldo & danzca6

 

I'm not having any luck in posting any pictures , but by all the info received I figure it's the thermistor and since this one does not appear to be able to be removed I ordered a complete extruder , I'll keep trying to up load the pictures , but I can not find a place on here to click on to do so , anyone ever sent a picture to be posted on here ?? Thanks

 

Just found a way to send the pictures , anybody know what model or anything else about this beast , Thanks

 

Did the pictures post ??. I don't know ??. Who's Harry by the way , it says at the beginning to ask for Harry , but Geof answered , that was great to have someone answer and then everybody else jump in and help , Thanks

 

So what try an 8mm nut or 5/16" nut on the rod ??.

 

O k , Mark thanks , Can you tell me if the roBo company that I ordered the hexagon extruder from is the same as the one that in this one or at least will fit ?? I just look again at the company Webb site and it says sold out , I ordered two days ago I hope they can for fill the order , looks like they have run out of most all there parts ?? Can Harry tell me what's up ,

 

No I was using my iPad , I beleave an 8mm nut went right down on the rod good a 5/16 started and then jammed , Geof do you work for ROBO ??
