heat bed taking forever, not reaching temp?

Post by metrons » Fri Nov 07, 2014 9:09 am

i'm printing abs (for the first time) trying to get all the bugs worked out why my abs wouldn't stick to the bed. i read on the makergear website 110 for the bed temp. last night i tried to get the temp to 105 and it wouldn't do it. stuck around 103 FOREVER...

trying tonight the bed seemed to warm up fine when i was getting the prints going earlier in the night. now ive applied gluestick and that tape that comes with the printer. bed has been warming up to 110 for over and hour and its sitting at 103.3. doens't seem to pass that temperature at the moment?

what ...the ...hell...this is driving me bananas. why wont the bed get hot enough? any ideas? i am dying to print stuff in abs and i've been having multiple issues. thanks to this forum i'm getting each bug taken care of and closer to printing properly in abs. but i think my temps are just not there?

balls! i'm so excited to print and i'm just sitting here all night with nothing happening. frustrating

really appreciate any insight.

cheers

Ok you dont need 110 to print abs. That is too hot. 90-95c is where you want to be. Any more than that is wasted power. Your bed however should reach 110 but its at its limit and can vary depending on how drafty or cool it is where your printer is located. You dont want to print abs in a cold room or where there is any air movement

How old is your M2? The older 12v units had problems getting hot enough. I ran with a thin sheet of corkboard under my bed, and would insulate the top with cardboard while it heated. With the 24v upgrade, I got rid of both of those and just blast watts into my room willy-nilly since there's plenty to spare.

m2 is about 2 weeks old. i'm going to try 95 tonight. i read abs doesn't...do something until it reaches 105c? i think i'll try moving my printer into the closet and hope that will maintain more heat. i'm not in a drafty room though. hopefully tonight it will just work. UGH

2 weeks is perfectly inside the warranty window. Contact MakerGear about it, you should be able to hit over 100C (even if jim says its unnecessary) with a 24v machine. Support is part of the price of the machine -- use it :)

Yes a 24v machine should get above 100c no problem unless you have it in a cold shop or something like that. Somewhere around here there is a thread where we did some timed tests of new and old machines. 100c was around 18min on old machine and the new was like 14-15 min.

good to know. thanks again gang.

got some support from makergear just now. they asked if i have a multimeter. i do have one, i've only ever used it for checking batteries charge though. any thoughts on ...how i would use my multimeter to check if my bed is working properly? that stuff is beyond me. i'm not sure what they want me to do with a meter. really never used it for anything but batterires.

This feels like a middle school "jane wanted me to tell you she likes you".

Explain your concerns to MakerGear, and let them walk you through usage of the meter. Josh (who is likely the one helping you) is very competent and can walk you through rudimentary troubleshooting.

MakerGear is going to want you to measure the voltage at the plug for the bed, as well as measure the resistance of the bed (is my guess). Neither of these is difficult to do.
