Thats awesome man!, well done,
That's such a good price, and your getting awesome results! your layers are coming out well,
I only print around 10-30mm's,.7mm nozzle, .5mm layer height using nylon, going to try a .4mm nozzle soon, I have to also dry the hell out of it b4 use, I use a cheap hair dryer and wood box, for a couple of hours, surprisingly the hair dryer can run that long with out burning out haha, i need a food dehydrator or something.
Last night i printer an x carriage using timmer line, used a fan, did not warp at all, but must of cooled down the nozzle to much and i had a few layers that did not bond, put it on b4 bed last night.
I am currently printing on painters tape, no heating on the bed, it sticks exceptionally well to it, the only problem if it warps, it lifts the tape off the print bed.
Using cheap painters tape, had more of a papery feel to it, where the expensive painters tape i have, feels like a very waxy surface, bonds to both but better to the cheaper stuff.
In fact its bonding alot better than PLA.
I prefer printing nylon over PLA, just have to make sure its all ventilated, With my new printer, should get it in a few weeks, it will be all enclosed and can suck out all fumes.
apparently Taulman nylon thats designed for 3dprinting is much safer to print with over line trimmer line as it may have different chemicals.
My plan is to get a another printer, and then rebuild this current printer from scratch,better bearings, aluminium structure, thicker rods, make it rigid and heavy, bigger steppers, New extruder design, i cant stand my current extruder, it only works well for slow mm's prints. I was going to kind of copy the aluminatus design.
