I've added a counter weight to the bed. Two reasons (make it easier on the z motor)(table does not drop when turned off; making it easier for bed leveling).
I was able to make changes without permanent changes to m2 (drilling etc).
list of parts:
1- achor that attaches to frame (printed)
2- 2 skate style bearings
4- 2 dowel pins
5-3/16" Round Urethane Drive Belt
6- 4 lb (1.5x1.5x6) steel counterweight
7- several printed parts for (pulley assembly)
updated pictures so they are easier to see
