More work on the print bed. Will reduce the spring height.
Construction is nearly finished. Wiring next and also a heat containment box.

Built a drawer for the power supplies and electronics. It will be a bit awkward running the wiring under the machine but will be tidy and keep the electronics cool. Got the cable chain for the bed heater done.

Installed the end stops today. Wasn't particularly looking forwards to this step as I hadn't integrated them into the design. However I am happy with the result. Just the Y and Z cable chains to install.
Z axis end stop.
Y axis end stop, I had to remove the plug housing and bend the pins to make it fit.
X axis end stop. I am using nylon screws for adjustment to reduce damage if there is a failure.
The end stop stand offs are 6mm Festo air line. I made a simple fixture to accurately cut it.

There were lots of little jobs to do before I could start wiring.
Got the machine into the rumpus room near to the computer.
Attached the power supplies and electronics to the drawer.
Cable chains attached.

Nearly finished the wiring, just need to install the E3D hotend.

Working on the E3D. I had to relieve the hole in the plastic Bulldog mount for the large E3D heat sink and also make a shim to snug the heatsink up to the Bulldog body.

Started work on commissioning the machine. Successfully installed the firmware on the board. Well the display/smart controller works and I can get motor movement if I activate the end stops
Haven't connected the hotend and thermistor yet so am getting an error message there. Work in progress.

Everything is working now in both Repetier and stand alone. I haven't really got my head around the end stops and homing yet. Still need to fine tune the calibration but they are very close.

One of the cable clamps was the perfect size. The glass is pretty flat under .2mm over most of it and maybe a max of .4. The guage makes it really easy to level the bed.

Got some PLA so I needed to make a reel mount and a system to get it on the reel.
Loose PLA as delivered and a extension lead reel. It has its own bearing system which is surprisingly free.
Reel holder.
Simple method of winding the filament onto the Reel
(CNC foam cutter in background also 40% Slick 360)

Insulated the heater bed with teflon tape and 2 layers of fire blanket spray glued together. Also cut away some of the extruder mount to make it easier to get the extruder assembly on and off.
Ugly mod but will probably make a new extruder mounting plate.

Got the hot end running and calibrated the extruder. I found Thomas Sanladerer's guides really good. Am getting very close to actually printing something now.

Re: Prusa I3 XL Build log May 24, 2014 11:55PM |
Second print. I am very pleased with this result.

Had a failure due to the PC to printer connection so have changed to printing from the SD card Am experimenting with Slic3r now.
Precision block test at speed. I am impressed by the amount of overhang is achievable.
