I'm trying to figure out how to make my x-axis lighter, especially since I'm considering DDDE (Direct Drive Dual Extrusion). However, with the extra weight of the print head, I'm wondering what I can get away with for lightening the x-axis. My design's pretty conventional, and heavily based off of the_digital_dentists' UMMD, with the exception being that I don't currently have access to metal milling capabilities (although I am looking into adapting my Anet machine to be a low quality leadscrew based mill). As such, I'm essentially building entirely with 80/20 profiles and LDO linear rails. My questions are:
1. given the amount of weight I have on my print head, will just the rail be sufficient, or will I have to mount it to an aluminum profile. (I'm fairly sure it's the second, but it can't hurt to check)
2. If I were to use an aluminum profile to support it in addition to the linear rail, what is the minimum size I would need? (For context, I'm currently looking at dual titan/chimera, with possible full-head water cooling much later in design life. I am, however, considering the Itty Bitty Belted Extruder
3. Are there any alternatives to an aluminum profile that would work better: materials, shapes, etc.
Cheers, and I look forwards to seeing your replies!
