As for budget for the new machine probably around $500, could go a little more. I would mainly be interested in a machine that has a little bigger print platform than the simple metal and the ability to print abs, petg and various other filaments. I’ve seen the upgrades that have been done to the simple metal like heated bed, axis upgrades. But I’m really wondering if it is worth putting any money into a machine that old to get it to print what a newer one can now. Plus I have no clue how many miles are on the belts, motors, etc. I’m looking into using the starting gcode to tweek some things since nothing else seems to work. I’m not holding my breath though since I noticed a g29 auto level command is in there, however I’ve yet to see this printer check the z axis more than once.
