Hi guys,
It's seems works now !
for that:
1) i have removed one of the roller wheel (3 roller wheel to support rim now)
2) I also reduce thickness from the roller wheels to limit the friction.
with to motor 12v 5rpm rotation is good but Holding the 2 motors with the hands!!
The next step is to fix the 2 motors!!!
thanks for your advices.
When I finished I will post on this thread the VariCAD schematics file of this arcade cabinet.
