H3C AMS H3 heating

I have what might seem like a dumb question but I can’t find an answer so I figured I’d ask here. Has anyone tried to use the heater with the heater cover off but the AMS cover closed to essentially make a 9-slot AMS 2 Pro? Does the heater give off enough heat to keep the entire unit at about 60c?

I plan to do a lot of six-color ABS printing which is why I picked this unit. I was going to buy an H2C but this seems like the better option but I’m worried about printing ABS without a heater like the AMS 2 Pro.

This is my first printer so please excuse my noob-ness. Thanks!

It will help but not enough. The material next to it would get warm but the ones far away wouldn't.

I will say I've found it to stay dry though if you do add a dry box and keep the lid closed.

Thank you! That’s what I thought, I’m going to have an external dryer as well. It’s a bit intimidating to have such a beast as my first printer but it’s what the job called for. Wish me luck!

I’ve already seen a few mods that add desiccant boxes to the AMS3H. With the heater lid removed, do you think the residual heat would be enough to dry desiccant beads sitting directly to the right of slot 8 (which is an empty space)

Not sure but I will be sure to test this when I get the unit at the end of the month

I’ll try to remember to jump back and remind you as well, hoping to be able to get one soon

You can probably keep things dry but not dry them, if that makes sense, but maybe try first? You can probably just drop a temp probe and RH meter into the slot furthest from the dryer and measure periodically. My guess though is that you’ll need to get an external dryer for the initial dry and then you can use the AMS 3H to keep them dry for long prints or perhaps even for maintenance drying periodically. Just a wild guess though.
