Dude, just wanted to say, I just found your channel this evening, and have watched through a tonne of your videos in one sitting. You are an extremely talented engineer, and clearly very hard working! Do you have a Patreon or some other support platform setup?
Hi and thanks for all that praise! I'm glad you found my channel since its mainly for passionate people like you that I make videos in the first place! No, I don't have any support setup, but I thought about creating a patreon at some point this year since the algorithm is kind of bogging me down...
Don't worry about the algorithm, your content speaks for itself, and in my humble opinion, it's just a matter of time before you blow up! Keep us in the loop for whenever you setup a Patreon, because you have a unique gift to offer the world, and I (and many others) would be willing to help you continue this kind of content indefinitely. All the best dude!
@@ConorFenlon thank you, I can't express how much that reliefs me! I know there are certainly enough people who like my content just the way it is, but it's hard reaching them without the algorithm and I feel by following the algorithm too much that unique gift as you call it would disappear. Because the best content I can make will always be about the things I'm most passionate about - so yeah, I hugely appreciate the support! :)
Maybe you are addressing/answering this in a later video in the series, but I haven't gotten that far yet :). Can you elaborate on your choice to have the X drive on the toolhead vs having it statically mounted to the side/start of X axis? Side mounted/static placement could benefit wiring and toolhead weight and size.
If I didn't adress it in the design videos I don't think I mentioned it elsewhere. The reason to put both motors on the carriage was just the steel fishing line drive mechanism, because it doesn't work with fixed motors. Later however I found out my steppers don't work with microstepping anywhere near as well as I had anticipated, so I will have to switch to lead screws with fixed motors to get any kind of usable resolution out of it. Toolhead weight would have been important now in direct drive while it can move fast, but as soon as lead screws come in it'll be much slower and toolhead weight will be negligible (which makes the move to a stationary motor kind of ironic)... For the wiring I actually prefer the way it is now because I only have to run one big bunch of cables to each carriage as opposed to the carriage and the axis...
Relatively soon, but I still have to finish the soldering station as well as the pen plotter, and everything takes at least twice the time if I make videos about it. 😮💨 I'm completely overloaded atm 😰
Design decisions are sometimes a bit frustrating. I do know how it's intellectually exciting to use existing parts and try to wrap your design around them like you did here ua-cam.com/video/8yAx6KrPyr0/v-deo.html but it's a painstaking process actually. Building parts from scratch is easier in my experience and less time consuming. Modeling existing elements takes time and you have to weigh the ratio benefit/time. Can't wait your next posts.
Yeah, I considered rebuilding the gear reduction from ground up and just mounting the large gear and the stepper directly to the MDF backplate of the carriage, but then I would have had to worry about attaching the shaft to it properly which also would have posed problems with clearances... But ultimately it's just the prototype, I think to make version 1.0 more accessible and simple it'll have just lead screws driven directly by the steppers. That should, although compromising max speed, get rid of most issues with the low stepper resolution and complexity.
Big thanks to my neighbor for letting me upload this over her internet after I had a total blackout last week!!!

Weldone have you unipolar stepper motor cnc machine project
Not yet, though next up will be a unipolar laser cutter/engraver CNC :)
when are going to build it
Relatively soon, but I still have to finish the soldering station as well as the pen plotter, and everything takes at least twice the time if I make videos about it. 😮💨 I'm completely overloaded atm 😰
