I havent posted in a while, as I was waiting for parts to arrive.
I found that the 6mm thick belts were useless, and had too much backlash for the Y-Axis. This meant that I could not get any consistent cuts.
I wondered if it could be the idler pulleys, the belts, or even the way the belts were mounted.
In the end.. I changed a few things.
Here is a picture with no X-axis installed
Also, upgrading the X-axis to 2040 extrusion, instead of 2020.
Here is a bracket I made from 6mm thick aluminium flat bar. Mounted to it is a belt mount that was sourced from cloudray on aliexpress.
The other side's bracket
X-axis aluminium extrusion installed, along with the linear rail and the first of the 15mm thick belts and idler pulley
Here is a close up on how the 15mm belt is mounted and tension-ed.
Here is the other side.
Finally, here is a picture of the timing pulley... its huge!
