ABS prints turn bed off when print begins

[thomasvanfossen6]

Hello, so I've been printing in only PLA recently. today i tried ABS and the bed heats up fine... however once the printer actually  actually starts extruding the bed turns off. any ideas on what it could be???? Also i have checked my slicer setting many times to insure i hadn't checked something bizarre...

a few things to check:

1: check slicer configs to make sure you do not have different bed temps depending on z height

2: what happens if you set the bed temp manually and leave it there for a while?

3: power supply - what type voltage and watt rating

what controller and wiring setup are you using. what gauge of wire and what's the length between board and bed

thank you so much for responding.

1: yes I've checked that config already.

2: if i set it manually it stays there fine at 110. i did an hour test and i never saw a change.

3: the voltage is 110v and idk on the wattage. its a good power supply though.

You are 110 to the bed?

Post the gcode somewhere ( or email it to me directly) curious if there is something odd in there.

thanks! sorry no its 12 volts to the bed. I've looked at the g-code but a new set of eyes will be good, ill share it with you... by the way it happens as soon as the motors start moving and goes all the way down.

Ah that's interesting. 

What controller? Part a pic showing wiring.

here they are.i am using a ramps 1.4

[bill]

Are you running separate inputs for the bed and steppers? ( Egypt both inputs)

are you using both dc inputs or did you jumper them?

[Bill Schwanitz]

err thanks spell checker - meant EG not egypt. technology fail

[thomasvanfossen6]

i used both

[Bill Schwanitz]

wiring looks good from what I can see. 

The gcode looks fine, I don’t see anything obvious there - no temp changes once the initial bed / hotted temps are triggered.

What happens if you set the bed to 80-90 range and then print? It almost sounds to me like something is not right on the controller board. Check for loose connections.

Has anything changed recently with the config? Has this worked in the past or is this a new problem?

don’t expect good adhesion in the 80-90 range with ABS. Thats more for debugging than anything. That said I tend to print ABS at 105 on the bed - not a big difference from where you are though.

Have you run the pid tuning and such? How recent is marlin? Anything interesting in the console logs from the print? May be an interesting / helpful debug message in there. If you are using octoprint there is an option to save the console log to a text file but that is disabled by default.

Thanks, sorry for taking so long to respond. the 80-90  range still has the temp drop when print begins. i have not changed config recently. i don't know about loose connections... it prints PLA fine. it maintains 60 degrees very well. i have updated pid recently but still no help... i don't use octo print i however use astroprint

I completely forgot to check back in did you get this figured out? If not bring your printer next week and I / others should be able to take a look
