that bolts are seriously painful for your E-Chain. try to switch to countersunk.
you might wanted to use even smaller and sturdy E-Chain, we can help you save money for next project. please consult to your IGUS sales for #1400 or cheaper, i notice you put only 3 cables. the "play" you mentioned happen because you have unnecessary height for chain interior.
@molceonly The play I mentoined was the amount of space the E-chain had between the 2 beams and not that of the wires. Those bolts do not hurt the echain, I get a smooth motion out of the chain, no bouncing off of any bolts. The reason for the larger E-chain was for potential future upgrades to a spindle with water cooling.

I like the solution you came up with to solve the flex issue. But, as I see it, could have been avoided by putting the shorter axis where you have the long one...
@johannas58 Yes, I could have done that, but because of my shop layout, this was the only way I would have room to slide my full sheet materials onto the bed. If I had more room, building the Y long and the X short would have been the best solution, absolutly.
This is very nice. Can you elaborate on the deflection issue? If the long axis is mounted to the table as 2 rails sperated by the mid axis distance, and the gantry moves forward and back on the 8020 (1545), is there really deflection?
@RianoKan Thank you. The 8020 it self will twist/bend when under load. The way my beam is made I do not have any issues on the beam it self. For me its the carriages on the Y axis that twist, as well as the X axis carriage tends to twist, flex, etc if I place enough force. Maybe Deflection is the wrong word? I'm no engineer. But when the beam is under force (the 8020 that is) it will flex a certain amount, and this was very noticeable at the 10' beam length that i have. (8' cutting area)
@MrFrabcabert Yeah, but will it bend if it is fully supported from below? I am making a 6' axis with 2 1545's. I forgot to mention, there will be a 1/4" steel plate on the top to act as linear rails, so maybe our designs don't match up. I hope it works.
@RianoKan I'm not sure what you mean with supported from below. Mine is attached to the Y Carriages at both ends. At 6' with a double beam and a steel plate on top, I think you will be more then fine. Things you will need to consider are the weight of your router/spindle. But that shouldn't be an issue at 6'. My carriages flex because they are made out of MDF. Aluminum would have solved lots of issues.

@MrFrabcabert Oh, I thought you used 8020..

@RianoKan the beams are 8020, the carriages are MDF
MrFrabcabert 2 months ago
@MrFrabcabert I get it. My beams will be 8020 1545, with 1/4 " steel plate, with aluminum carriages that ride on the steel. Thanks.

@sdougm Machine like mine will go for around $4000-$5000 with software. You wouldn't need something that big though.
