heater temps for cjv30

That's about right.
I think mine is 35 40 45.

Here's a tip if you want to turn off the heaters at will.
Switch to cut mode and press the heater/cutter button twice (then enter).

I found that because I drive this machine through Signlab, the heaters would fire up and stay on even in cut mode when I just want to cut something.
Being able to turn them off is handy. Pity you can't do the same override in print mode.

 

Lately, we have been running hot. 45, 42, 50. Banner, and all other vinyl seem just fine with this temp setting.
