07 Sep Equipment Upgrades
Over the summer I spent some time upgrading the CNC Router and finally finishing the large 3D Printer.
The router is on it’s third iteration. It now has two stepper motors on the X axis, which will allow greater rapid speeds and acceleration and also make it easier to keep the gantry square, as each motor must now have it’s own home position. The z axis uses a ball-screw and nut, again for greater accuracy, and the touch off sensor makes for much easier tool changes. It took me a while to get to grips with the new methods of setting up a job but the machine is a far more capable than the old one. I am sure the hand forged feet have also made a difference to performance somehow. Much thanks goes to Dave Griffiths of [foam] kernow without whom I would probably still be struggling with the configuration files!
The 3D printer is now finished apart from getting to grips with slic3r settings for a large .8 nozzle. It has a build envelope of 450 x 450 x 450mm. The aim is to be able to print some rather large models and possibly to make furniture and house hold objects. The initial idea was to make a
machine that could print papier mache, however I think I should learn how to print with PLA first. The first big print is a large lamp base 350mm high which took 12 hours to print.
