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...

[MrFrabcabert]

@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.

@MrFrabcabert well, than it's a very well build beautiful hybrid monster. love your works really.

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

[MrFrabcabert]

@RianoKan the beams are 8020, the carriages are MDF
