Your belt will be more like 2m to 2.5m long with a cutting area you're looking for.
Thanks! I went through your build log, nice work!
I’m also into RC and are really looking forward to get the machine ready.
After all the input from you and others here I will probably go for the IP-M and I will slave the X by belt.
About the belt and pulleys . Can you recommend any products? If I remember correctly the distance between the centers of my ball screws is 684 mm at X.
I was figuring twice that + a little for the pulleys and some kind of tension adjustment device at center.
