Known problems
Shifting in the Y axis
There are two reasons for shifting in the X or Y axis.
- V-Groove wheels adjusted too tight
- Electrical box fan configuration
To properly adjust the V-Groove Wheels go here: Calibrating your Gigabot
Gigabot has undergone several revision from it's inception. Early Gigabot printers had one of several different configurations of the cooling fan for the electronics box. Through the change in fan configuration we have found that some of those configurations have caused the motor driver for the Y axis to overheat and cause shifting in the Y axis during the print.
The current and stable design is one cooling fan on the right side of the electronics box blowing air in and one fan on the bottom of the box blowing air out. With this design we have eliminated the shifting of the Y axis.
V-Groove wheels may be out of round
We have found that some of our V-Groove wheels can be slightly out of round and cause the hot-end to move up and down as you move the print head in the X or Y axis. This should be immediately apparent if the dial indicator reading moves up and down in a cyclic fashion when you are leveling the bed. Please contact us at support@re3d.org if you need replacement wheels.
Adding a second fan to the print head
We have also found the quality of PLA prints to improve when adding a second cooling fan to the print head.
