Solved Anyone ever seen this?

First post - love my Robo - been using it quite a bit over the last month. Yesterday did a few prints. Last one was a short 2 hour print - parts printed fine. After print, went todo my normal cleaning of bed and noticed part of bed appears to be melted (appears, not saying actually is)

I left it be and this am was going to fire up printer and do test print, of course not on top of this, want to make sure everything else working before i try and figure out what todo about bed.

Heres some iPhone pics - anyone seen this? thank you - John

 

thanks guys - i am currently doing another print - was worried something else up too - guess my nature - anyways all else good and I'm sure ROBO will take good care of me - for now glad this spot isn't in a "high traffic area" and can work around it - at least to finish some projects today - cheers

 

Robo3d offered the bed to me at $45+shipping because they can't warranty the part. But that's half price so it was a good deal.

 

I literally just found two chips in mine as well less than 1/2 hour ago while cleaning the bed for another print. It looks more like the nozzle melted the glass or ground it somehow it than a chip. Can the glass be ground or melted like that by the nozzle? I did go ahead and report it to Robo. They are going to put me on a no-fly list soon with all the parts requests I've sent in this week, sigh...

 

I recently got a tiny hairline spot after using PETG the first time (ext 245c / bed 80c). I went on to print many more prints using PETG without a problem. The first print I switched back to PLA+, this happened:

 

I contacted Robo already so I'm waiting to hear back from them. I've had the printer exactly 2 months, I don't know what it wouldn't be covered under the warranty. To me, it seems like it would be a manufacturer defect. It's not like I've done anything out of the ordinary with it. I haven't even disassembled it (yet). I plan on doing @WheresWaldo Y bearings upgrade when I have to replace the bed.

 

When the glass bed on my original R1 was shedding slivers of glass I was told that unless it was damage from shipment it isn't covered by the warranty and that I'd have to buy another bed (at a reduced cost from just buying it as if it was a spare, or whatever).

 

I have the solution to ever having another chip in your bed. I have 14 Robo3d printers and have had 3 chips from the bed. I replaced the bed and added a PEI sheet to the bed. Two problems solved. One... no more chipped beds, Two.. No more need to use anything glue stick or hair spray to get PLA or ABS to stick to bed. Full bed prints in ABS no warping. Warning high temp filaments like Nylon, poly-carbonate use glue stick so that you can get the print off the bed. Also glue stick for Ninja flex. Great material. See this youtube video.

 

Back when we were doing prints for that CES contest I was having a hell of a time getting the parts for said contest off of my PEI sheet when attempting to print them in ABS, and they pretty well filled the build area of the bed.

Granted, I was running the bed closer to 100C and then cooling it by 5-degree stages down to 80C every 150 layers, but still.

 

You have to use common sense and use the bed as it was intended. The outline on the bed shows approx area of heater on the underside. That is why they call out a 8'x9'x10' build volume. That is also why the heated bed is required for good ABS prints. I have 14 Robos and been printing since The first Robo was put out. I know what I am talking about.

 

Glue stick will make it easier to remove parts from PEI as mentioned above
