Yes, it's going to be a big build. Most of the linear rails/rods, heatbed and screws have already been sourced. I've got the 4040 extrusion cut for the frame. It's OVER 60lbs. I have strength in mind. The heatbed will be ran off of a wall socket, with the board controlling the temp. I've sourced a dual zone heatbed as well. It'll heat the center, or the entire bed. About 170.00 for the whole unitby eninja67 - General
Yeah, bigger is better, right? (not always). The frame is built from 4040 extrusion, not the "lite" type. 15 series I think is what it is (solid outer edge). I already have the frame extrusion cut. It weighs a little ove 60lbs. I cut the extrusion with my slide saw, using a high tooth count carbide blade. Cut like butter with silky smooth ends. I already have a dedicated place in the house whereby eninja67 - General
I was looking at the grade 5 titanium. It's MUCH stronger compared to grade 2. I've worked with it in the past (chainmaile) and it can be a booger to work with, especially when it comes to cutting it.by eninja67 - General
Saw the video DjDemonD, and was impressed. Same build size I'm wanting to build. It's nice. As far as with x/y axes, I was thinking of using titanium rod/tubing with Drylin bearings. I have not seen actual titanium linear rails, while duing some research. I was thinking of using the Drylin bearing with the titanium rods. It would make a good combination for strength and lightness. I've sourced thby eninja67 - General
I really appreciate all the advice so far. Great information! My plan IS to print larger objects, so I do have in mind for the cost, and the challanges that come with building a large 3D printer. My plan it to make sure my frame and all the axes will be able to take all the loads, but I have lightness in mind when it comes to the x/y axes especially. My z axes will have a machined aluminum plateby eninja67 - General
24 volt was going to be a definite. Can the boards handle nema 23's?by eninja67 - General
Hello everyone! I'm new to this forum (and 3D printing as well), and was hoping I can get some advice on my very first project. I'm building a corexy printer (MAYBE an hbot) with a platform size of 600mmX600mmX1000mm. I'll be building the frame from 4040 aluminum extrusion. It's NOT the lite version. I got a fantastic deal on eBay for it, even with it being used. (45ft for $40.00). I paid more foby eninja67 - General
