Custom Size Frames / Re: Building an eggbot type laser
« on: February 14, 2018, 03:13:15 PM »
I did have time to get the laser wired up today and played with it a little. I think maybe now the real work starts. It seems to me the y axis is much too fast and the x axis may be a little slow. On this machine the y axis is the rotation and the x is the laser travel. Also, the aspect is all wrong. I really won't get another chance to play with it until maybe next Wednesday or Thursday. I believe I'm going to have to change some feed rates and other settings but I don't want to affect how T2 works with my other machine. Can I created a profile for one machine and a different profile for a different machine?

In case I would ever want to do one with a range finder do you think it would be difficult? Not the mechanical part, I think that would be pretty straightforward. The electronics would be difficult for me. I know I have seen an arduino laser range finder shield somewhere but not sure just where. Have never written a sketch but it seems a simple if/then script would be necessary as well.

Range finder sounds like an excellent idea. Especially for solids. I was planning on adding profiles but that would be a lot of work.

I also think a mechanical follower with a free floating z-axis may work. I would think it would work very well  on glass. Just not sure how it do on a surface like wood that has grain.

Thanks for posting. I have just finished building a rotary fixture for etching glass and am interested in your results. I think a third axes for keeping the laser head at a constant distance would be necessary. What power laser and lens do you have?

I thought a lot about the z axis and how to address that. Finally for this one I didn't feel it's necessary for my intended use. In my mind the ideal situation would have a range finder running a stepper to keep the axis  within a couple millimeters. Don't know for sure if that's doable, at this point I'm sure it's not doable for me.
My laser is a 3.5watt ttl with whatever lens came on it.

Why 2 steppers for the rotation? Weight?

That's part of it of course. The Mana SE supports two steppers so I figured why not? That, and they are so affordable at about 7 bucks apiece it's very cheap insurance. I'm also looking ahead to building one of these that would have a lot more capacity. The biggest form I've turned is about 15" high and 14" major diameter. Something that large would benefit from being driven from either end I think.

I have posted as unlisted and apparently a person needs a gmail account to view it. I'll change it to public for a bit.

Okay, have made some progress on my custom build and would like everyone's  thoughts, am I on the right track? The machine as it sets has about 10" capacity in length and about 8" in diameter. This is a project to see if my idea will work, to learn, as I'm not an electronics guy, and hopefully to lead to a larger build in the future.
I have lots of questions and I'm sure there are questions I haven't considered as yet. At this point the laser is not hooked up. Hopefully I'll get that done today or tomorrow but then I have to table the project for a week or so.

I assume I'm going to have to calibrate the machine so I know how far one rotation is in distance for both axis'? The wooden face plates are temporary and will be replaced with aluminum ones. It's my intention to use this machine to burn geometric patterns and do layout on things like small wooden vessels, ornament globes, bangles, etc. etc. I will probably use inkscape to draw most of patterns.
I appreciate any and all comments, positive or negative. Suggestions to improve on the idea are welcome as well.
Thanks
Steve

I want to make up a wiring harness to hook this up but all I can find at the local hardware is doorbell wire and I don'e believe it will work well. what gauge stranded wire do I want to buy to make a harness?

EleksDraw / Mana se drivers
« on: February 04, 2018, 05:41:37 AM »
I have an eleksmaker A3 with the nano controller. I'm trying to build a new machine and the controller I have for that is a mana se. Do I need to install different drivers for that controller?

Only because I'm lazy can you shoot me a link to the latest and greatest version?

Okay, I have looked and looked and i don't see a rotary mode. I'm using V1.3w, do I need to upgrade? I'm looking for it while disconnected in case that matters.
