Geofs R2

mind you in a totally stock R2 I printed the majority of the build plate on the R2 with PLA with no warping

 

You'd be suprised the amount of people I've heard say the "r2 is unusable with PLA" lol

no heatcreep, no warp/adhesion issues. 20 hr prints x 8 so far

 

PLA gets a bum rap. 90% of what we print is PLA and if we are doing prototyping it is always PLA. The finish part might be something else, but why waste it...

 

Yea, that is a heat problem every time or bad filament. That bit me once.

 

Heat problems seem like the plague with people and the R2. I am beginning to think that if they do a temperature tower they would be suprised at the results .

Yea PLA for prototypes, cosplay, trinkets...when people want something cheap lol. We run alot of it and alot of co polys, ABS and polycarbonate. Hell I still use PLA for my pachinko mechanical parts (4 year old parts are still holding up to every day play just fine in my non climate controlled garage )

 

I dont think I'd have those problems. seems to not have those issues with PLA at the moment. Also without running their settings I dont think I could mimmic their issues.

 

I am not having heat creep issues either. I am not a fan of the heatbreak used in Hexagon extruders. It is not the most efficient heatbreak design. But I also found that leaving off the front cover for the extruder has a measureable impact on temperature.

 

I removed the front plate because it annoyed me visually lol. I perfer to see the hotend while its printing without a big "shadow" in my way. The plate does get quite warm if the hotend isn't positioned just perfect and acts as a heatsink. I likely wont be putting it back on until I finish my redesign of a cooling set up that I like.

 

I am not very far with redesigning the fan shroud. I did model the OEM shroud. It is not 100% exact but it is based on actual measurements from the Robo supplied fan shroud.

 

I had to stop due to having to run the machines, including the R2 to stay up on the orders. Wasn't expecting that and am glad its performing well lol.

 

Thats what I heard. That and polysmooth. I have a spool of each. Will work them through shortly. Where do you notice the jam from heat creep?

 

Sounds good. Will give it a go. Did you notice the cold end being warm?

 

lol. No worries I'll give it a shot and find out. If the cold end is getting hot then @WheresWaldo or I will have a fix with a 30mm fan mod (one of us will find some time at some point lol)

 

Update:
I have ran : Taulman 910, colorfabb XT, NGEN, PLA (hatchbox, foxsmart, zyltech, no name china stuff, polymaker and colorfabb), PETG, Colorfabb HT, Bronzefill, Brassfill, woodfill, corkfill and semiflex with no issues. My machine is completely stock with the only changes being Acceleration lowered to 400 and jerk lowered to 7. I did these pretty much from the get go. I use S3D as my slicer and print via gcode loaded into octoprint.

As an update to failed items:

My power cord for my raspberry pi failed (shorted). After replacing it both the Pi and touchscreen were dead. a new Pi from the shelf and a touch screen (amazon) are installed. Machine is running. For the Pi power supply I had a old phone charger, stripped the insulation and used the black and red wires (power/ground), the other wires were cut flush and taped. Touchscreen thread in troubleshooting.
