3 Issues I see with this design. 1: Wet noodle. When this is extended more than a few inches, you'll be able to move the spindle visibly with your own strength. I'd guess you need to stiffen this by at least a factor of 10 to have it usable for more than drilling. 2: Accuracy issues. Those types of linear rail are not guaranteed to be straight. They need to be screwed down and and held against a reference (flat) surfaces. 3: Not much clearance. In the configuration you show this most of the time, with the axis as far up as it will go without coming out of the lower block, the spindle shaft sticks a couple inches below the gantry clearance, and any tool inserted in it will just stick out further. If you move the spindle up the rails, then the rails will have to protrude below the gantry when at it's lowest position. Linear rails are not a good substitute for a real frame.
@lucmartz3 ай бұрын
I'm taking notes @skrubol thanks for the feedback. The idea is to keep it simple and explore options, I will release soon some FEA analysis that will help me to take the right direction in this project, the screw down and held against a reference surface is one of the changes, but the surface will travel :) I'm having "spacers" in between the rails, the change will be to replace the spacers by one single spacer in steel with machined datum planes, the next limitation is the force of the stepper, yesterday I tool some measurements those can only handle 5kg (49N) so that is part of the constraints to take in count.

Im certain you are going to see a lot of vibration issues with the design, especially when cutting deep. You should try to alter the design so there is a more rigid connection with the rails and the spindle, especially because its sticking out

Yes, currently the machine has a max deflection of 0.4mm at the max force that the stepper motors can provide, I will post tomorrow a short video about how I took the measurement. I have done plastic parts with this machine with some acceptable precision but only happens when use the appropriate finishing passes with the right depth of cut. I will post soon more!
@amfcreations68943 ай бұрын
Ive made mine like that 25 years ago using a 16mm thick steel plate to suport the rails and its not as rigid as having the rails fixed to the gantry ,so i will change it for a fixed rail version. the max depht of cut in steel using a 10 mm end mil is about 1mm not good enough for me. So go for the fixed rail if you can its much more rigid.
@lucmartz3 ай бұрын
@amfcreations6894 oh well, you are more ambitious than me :) I hope to cut aluminum at the most with this machine because I have a constraint on the force that the steppers motors can provide, I have posted a #youtubeshort taking the measurement and it is 5kg at the tip of the spindle, so around 49N before loose steps on the steppers which is really bad.

I don't know the dimensions but, that kind of bearing assembly and ballscrew should let you put the spindle closer to the gantry. It will be hard to have it all really parallel. I quite like that you use the linear rail as part of the structure of the Z component. Check the deflection gantry it seems that it will be huge. It would be better if you could make a square beam using aluminium plates (aluminium tubing has too little wall thickness) and have the same assembly procedure as you have right now. Because the gantry is not moving, you can make it as rigid as long as the table/floor can hold it. In my case, I wanted a compact and easy to tune CNC so I went with a moving gantry but that design has lots of problems. Like: chip management, sealing against dust all axis, limited mass on the moving axis, big enclosure, difficult to assemble, hard to water cool all of the moving members, 4 motors for 3 axis, 4 encoders, etc.
@lucmartz3 ай бұрын
Thanks for sharing your experience with your machine Victor. Yes, Y axis movement defined on gantry movement is challenging, it is interesting why the bunch of plasma/waterjet CNC routers on the market that use that configuration exist, maybe is because the tool is not applying forces in the X and Y axis? The movement of the spindle closer to the gantry is very good idea. In order to do not leave the rigidity responsibility to the linear guide rails I will replace the plastic spacers with a single steel piece, but now that you mention the square beam using aluminum plates... I think I will go on that direction. I'm working on a new video where I show the details of the FEA analysis and future changes of the design. Thanks for pointing the "spindle closer to the gantry" improvement opportunity.

I've been thinking about it for last few days for my own project. My part is large enough that it will have infill. I'm sort of thinking that shell elements of just the walls might over predict deformation. While treating the part as being solid and using a solid elements as you have done will under predict deformation. BTW, I like your simulation and appreciate the effort it takes to get the FEA to work sometimes.
@lucmartz7 ай бұрын
@chuckd7177 how large is the part? The idea of run the simulation with shell elements will depend on the thickness, if you can control the setting of the wall thickness on the slicer, I think you can use for simulation a thickness parameter for the 80% of the actual wall thickness. Remember that layer orientation is key.
@chuckd71777 ай бұрын
@@lucmartzMost, almost all, of my work with FEA was with metals. I sort of thought about layer orientation after I wrote my first comment. I'm still thinking about it. I'm new to 3d printing (filament printer) and still learning. There are lots of options in the slicer. I "think" (meaning I have no proof) with infill (lots of options for the type of infill) the part would be stronger (less deformation) than would be predicted by just using the wall thickness as the shell thickness. Maybe I need to figure out how to do a 3 point bending test. :) I could quit guessing then.

I made to beams one was hollow and the other was solid. I hung weights from the center of each beam and measured the deflection. From the measure deflection of the hollow beam and using the equation for deflection of beam for a three point bending test I calculated the modulus of elasticity for the PLA plastic. The modulus matched fairly well with the value I found on matweb. Using the modulus I calculated from the hollow beam, I calculated the deflection for the solid beam and compared it with the measured value for the solid beam. The measured deflection was about 35% greater than the calculated value. Based on this very limited testing it would better to use shell elements for modeling of printed parts.

Hi, I have a question. I use Inventor 2017 and I do not have the command Insert End Cap, which I see has appeared in 2020. How do i insert plates at the ends of the profile bars? I want plates of customized dimensions, not from the library. I did this by drawing a part in separate file, placing it in the frame assembly and then it's impossible to constrain it on faces which are cut inclined. It seems to work inserting them with Joint, but it only works edge to edge, with no offset. If I need to offset the edge of the plate from the edge of the inclined fece of the steel bar, I have no option.
