Max safe temp for V3a?

[dsharp02]

I'm doing an experiment with ABS and HIPS, and I'm having some problems getting them to adhere to each other. It's been suggested that I try raising the temp to 245 to get better adhesion, but I'm concerned this would melt my groovemount. So what is the maximum safe temperature?

Thanks,
Dave

The official temp is 220. You can go higher. The v3a temp are a little different than a block style. I knowni ran my v3a higher but its been so long since i had one i dont remember exactly. I think you should be fine at 235-240 but prob wouldnt go higher than that.

I have a backup V3a if you nuke yours during this experiment, FYI.

I tried mine at 240 and out of the corner of my eye, I thought I saw it twist.

When I manually extruded, it went BANG, a huge puff of smoke came out of it and sprayed some weird pinkish substance all over the build plate. It was very difficult to clean off. Needless to say, that was it for that hot end. That prompted me go with the E3D I had been considering.

I would recommend not standing near it if you try it. There is still a crease in my chair if you know what I mean!

That sounds like you had a bit of PLA clogged in the barrel or something. What happened to the hotend?

I tried to take it apart to torch the nozzle, but the ceramic crumbled to pieces. Rather than fix it, I just switched over to the E3D since I didn't want to spend the $$$ to upgrade to 24V and a new hot end at the same time.
