Update

For those who read my blog sorry that it has been a while since my last update.
Since my last update some things have changed, the extruder cooling fan stopped working, I re-calibrated the bed, I've put kapton tape on the bed and I printed a clamp to hold the cables of the x-carriage.
The cable clamp was needed because the cables used to be zip-tied to the cooling fan cable. This made the cable a hinge which would bend every time the x-carriage would move. Eventually the copper inside the cable broke and the fan stopped working. I temporally put the big fan on to replace the small fan untill I've got a new one. 
I'm actually planning on to replace both fans (the on for the extruder and the one for the electronics) because the original ones make to much noise.

After some recent failures I decided to re-calibrate the bed, put kapton tape on it and get rid of the clamps.
One off the problems I had where because of unneeded tension in the printers frame. The tension caused the x-axis smooth rods to bend and cause the extruder to hit the bed on the sides while at the middle it was fine.
I've also started using kapton tape on the bed instead of hairspray. The hairspray looked so dirty but it worked ok. I don't know if the kapton tape will do better than the hairspray but we'll see.
The last thing I changed was getting rid of the clamps that used to hold the glass in place. Every time I printed something big the extruder would bump into one of the clamps and mess things up. That's why I've taped the glass in place with kapton tape now.

Upgrade #2 upgraded (again)

Because my previous version of the cooling started to melt away I made a new cooling unit.
This version is more compact and of course doesn't melt.
In the picture you can see two versions the one on the right is final version. The top of the cooling unit is covered with a layer of aluminium foil to reflect heat from the print head.

Upgrade #3 insulation

When I switched from PLA to ABS heating up the print bed took forever.
I got sick of waiting so I insulated the underside of the print bed. Now the bed heats up faster (I guess, don't know how long it took before).
As a precocioun I also insulated the y-axis carriage to minimize heat transfer from the bed to the bearings.

Small upgrade

A few days ago I replaced the metal clamps that hold the glass bed in place. I replaced them with smaller printed plastic clamps.

Upgrade #1

Today I printed the first upgrade for my printer. I printed an extended spool holder. The original spool holder was to short for the filament spools I bought.
As you can see I had a minor layer shift during the print. I hope I fixed that by increasing the stepper motor voltage.
