Help/Introduction

I am working hard on getting it right. I’m also trying to get the sled with the Z working right.

Getting the frame finally completed. So happy that I’m finally getting it all figured out.

Hi @Arykk,
Looking at your setup for the chain slack, I have to say it’s elegant, however I am concerned about the amount twist you are putting on your chain as it exits the sprocket. In general, you will want your chains to stay in the same plane at all times, and that plane to be the same as the plane of the sprocket. Twisting the chains will encourage chain skipping as well as potentially damaging the chain links. I can see from the previous picture that there is some mitigation of the twist by routing it down your main beam, but I still think that this may lead to problems for you. One solution that would still allow you to keep your weights behind the work area is to switch to a bottom feed chain setup and route the slack chain horizontally.

A couple of threads you might want to peruse

and

FWW - as long as you keep the chains parallel to the work surface at a reasonable distance equal to the distance of the motor gear from the surface you only need the motors. That is I eliminated my “idler’s” , or any mechanism to influence the chain angel entering or exiting the motors and have had no problems.

I will also state that if you put twist going in one direction entering a motor the chain exiting will attempt to move the same amount in the counter direction on the opposite side. Just like backing up a trailer the force moves in the opposite direction.

I hope that helps.

Thank you

Here’s where it sits now. I’m feeling pretty good about the set up (thanks Keith, those were perfect threads) and I’ll be hoping to get it going soon. One of the wires came out of the Z axis connections so I just need to get the calibration done and I hope I’ll be cutting.
