11.2. FIRMWARE UPDATE ON OLDER PRINTERS
If you have an older printer and update it a long time ago the first need to restart your printer. Follow
the next easy instructions and update your Firmware.
From time-to-time you may encounter a traffic jam scenario when attempting to upload this new
firmware; in some cases your CraftBot’s screen will go completely blank and even seem to be
nonfunctional… but do not worry! This situation can be easily remedied by following these easy steps to
fix this problem.
Take a look at your LCD display located at the middle top front of the CraftBot 3D printer. You will need
to get around to the back of the LCD HMI board to find erase button. The „erase” button is located on
the bottom right corner of the LCD or on the left. Switch off your machine. Wait 10 seconds. Press and
hold the „erase” button on the HMI board, while powering up your printer again. Wait 5 seconds, and
switch off your printer again and release the erase button.
Main PCB board
To erase the controller PCB Board, while your printer is still switched off, use a piece of filament to
insert into the „erase” hole which is located on the right side of the printer, under the USB / Encoder
connectors. Press and hold the button ( you should feel and hear a click as you push in this switch) with
the filament, while powering up your printer again. Wait 5 seconds, and switch off your printer. Now
both controller boards are erased. At this point the screen should still be blank and your CraftBot should
still be unresponsive. From this point proceed to the firmware update mentioned previously and after
uploading you should have a 100% operational CraftBot 3D printer again!
12. APPLYING A NEW LAYER
OF PROTECTIVE KAPTON
SHEET TO YOUR BUILD PLATE
Build plate Kapton sheets can get worn out over time, or it can be damaged by the nozzle due to
incorrect leveling. Reapplying a new Kapton sheet is essential to maximize print qualities if the old one
has issues. To reapply a new Kapton sheet, take the build plate out of the machine and remove the old
sheet by striping it off of the aluminum plate. Clean the surface of the aluminum plate with acetone.
