ABS Temperature Settings
January 21, 2015 12:32PM
Hi,

I have recently finished my first reprap build (A slightly modified steel framed Prusa i3), however, I am struggling to calibrate the printer. I want to use ABS due to the higher temperature applications it allows. I have calibrated the printer using triffid hunters calibration guide. The calibration has resulted in the following temperature settings: 194C for hot end, 115C first layer heated bed and then 110C from there on. To me this temperature seems to be very low as everything else I have read online appears to start around 220C, is anyone else printing ABS as low as this? I am querying this mainly because I am having an issue with corner lift when printing larger objects, this always occurs at the front right corner of a print and occasionally the back right corner resulting in a failed print after about 4 layers. Any help would be appreciated.

Thanks

I print ABS at 230c with a 110c bed. If your first layer is too high you can have adhesion issues as well.

I currently print using a 0.1mm first layer thickness a 0.4mm nozzle and use a glass heated bed.

My kits manufacture profile has ABS @ 230 and bed @ 100

I see lots of folks talk about the kinds of temperature you're talking about but I was getting charring on mine if I went over 205 extruder and 75 bed. With those numbers on clean Kapton over glass I do get corner lift if I don't zero the Z axis to get a little squeeze on the first layer. It gives a little elephant's foot but not much (and with ABS the sanding is easy as needed).

205C?! thats fairly cold for ABS, heck ive ran mine up to 270c before with no ill issues.

I have now bought a role of Kapton tape and applied this to the glass heated bed, the effect has been outstanding and has almost completely eliminated the corner lifting. However I am still printing below 200C, I bought my kit from Sainsmart, the kit included 2 100k thermistors, however, I don't know what exact thermistors they are so I have just used the 1st table in the firmware can anyone confirm whether this is right? I think if they are not the 1st table my printer maybe reading incorrect temperature values.
