I can vouch for the seemecnc neon orange, dark blue and black ABS sticking to glass/hairspray over mhackney's aluminum plate on the onyx at 80C (thermistor reading), hot end at 232C. The thermocouple on the glass reports a bit lower.
Of course, if I don't squish it on there, then it doesn't stick. But I haven't had bad warping. I could probably make it warp by blowing a desk fan on long thin parts. But for example I printed the
spool holder extension kit today & needed a razor to get it off the glass.
