Getting good prints.
The ORD bot has given me new found reliability. I can now confidently leave my prints unattended.
Prints not adhering well to the print bed has always been an issue for me. Either the print would totally fail to stick or lifting would occur soon as the print go a few mm high.
Using the ABS juice method
initially gave me good results but large prints still lift. Reading thru the thread, I decided to try nophead's method. I pre-heat the bed to 130C and print the first layer and have the bed reduced to 100C after. This together with brimming
completely fixed my lifting issue! I think there is also a variation in how you apply the ABS juice. I apply mine now on a cold bed using moderate thickness. It's definitely not as thin as how nophead
Anyway, just want to share some nice prints.
My next problem was de-lamination. Using the previous 0.5mm nozzle, I never had problems with this printing at 0.25mm layer. The layers were always very well bonded. I also always use only 2 loop perimeter.
As I switched to a new nozzle (0.35mm, or maybe it's 0.3mm???) and continued to print as before, delamination of prints is a big issue.
I printed this monitor mount
and decided to give it a simple strength test and the part broken without effort.
To solve this, I now print at 0.2mm with 4 loops perimeter for parts that need strength. Also I think it'd better to orientate the parts so that it will not fail on layering axis.
Comparing the quality with previous sprinter, Marlin is visibly superior. Also emaker's version of the software produced a lot of surface bumps.
I went a bit over-zealous with the flame polishing!
I think this concludes my build log. Thanks to bart for the great design.
