Hi, nice machine, I built a belt drive router too with dual 16mm wide AT5 belts on the X axis gantry, I found the weight of the gantry (about 30~40kg) caused the gantry to bounce when decelerating at higher speeds than 1000mm/min.
I have played with acc/decel settings in Mach3, but can only improve it with really slow decel so squares are rounded,
have you noticed any bounce when doing fast moves in X?
The bounce shows on the part when doing an X movement, then Y movement.
Nice work! Just curious in comparing belt driven against ballscrew, if the belt stands the load while cutting? Which is better for you?

Starting at 1:13 it really sounds like a police chase scene in a cheap 50's TV show. :)

its really cool. but it seems like a lot of energy to built a quality CNC machine just to do the robot...

@WingChunLover2 probably not there to show how it moves.

@minisoft1 There is a table/plate that is mounted above the bottom of the gantry, which is where you place your parts.
