Combine Maslow 4 with one of the new 30-40 W diode lasers and you have an amazing large format laser cutter. You guys should consider partnering with one of the makers of these laser modules. All of that, of course depends on the accuracy being substantially better than the previous versions.
@@AllenAlberti is right. There's also a connector on the board for it to plug in. The only question is can we get liability insurance to cover it or will it be sold as an add on by someone else
Those diode lasers are insanely dangerous for your eyesight unless you are wearing goggles, but you can say the same thing about a saw. I guess having a fire detection function would be a good idea. One nice aspect of this would be the ability to laser cut off the tabs when you are done with doing the CNC cutting. I can imagine some future version would switch back-and-forth between the two cutting methods, depending on the amount of small detail in a particular area of the job.
@@macrumpton That's my concern with the lasers too. It seems WAY too easy to accidentally blind yourself also I think that there will be issues with cutting materials that produce toxic gasses without good ventilation. Basically it's supported in hardware and software so you can plug a laser in and it will work, but I'm probably not going to sell one because I don't think it's really safe
Hey, I like what youre doing so big props and I'm excited to be getting mine soon. But I want to voice a little concern about the strength of the motor mounts. Its apparent they are flexing when pulling the sled in that direction. You can cut me off here and say that based on your professional opinion, its all good. I just want to hear about it because IMHO, its too much movement for that size gear in the belt. It suggests to me that there will be a greater possibility of skipped tooth down the road. The frame might be just fine, but maybe there is a torque check you want to do to initiate the release of another(other) motor(s) so this flexing one gets relief. I'm very much about the idea to "keep it tight" but I see something worth looking into. Please, keep with what you are doing. I'm just trying to be supportive. Cheers!!!
100% I agree. I agree so much that it's already changed :p ... A couple updates back we mentioned that we extended the motor shaft and now there is a bearing on the opposite side so the motor wont wobble at all. I just only replaced one arm because 1) I didn't want to reprint everything and 2) I wanted to keep running the same motors longer to make sure they hold up. I've been using these ones for about a year now and I wanted to keep pushing them to make sure they last
A around 4:10 you can actually see the difference. The lower right motor has different color wires and that's the one with the longer shaft supported from both sides...it doesn't have the same wobble that the others do.
Thats awesome. Loving your attention to detail! I feel silly for calling out things like this but then my engineering mind went to reeling about how this can be a bigger problem than the mount flex. For example if that motor gets to running and slide isn't moving, there ends up with a level of error in the resulting cut. Essentially the motor is given the command to move but nothing happens until enough force is put into that direction. Which suggests to me this amount of pre-load has to be acknowledged by the controller as a part of router motion OR you will want to tweak your calculation on cable release from other directions. There are a few things that are peaking my interest on factors of motion control. Length of cable which results in two factors, 1- stretch and 2- the % of error at outer regions. Another is a factor of router sled weight to be considered when vertical or horizontal - the implications here are that in a vertical configuration, there will be a degree of motion error in vertical travel. Another is a consideration on the amount of sled rotation and movement due to mill-to-pieces engagement. This will always be a problem with this kind of router compared to a rigid gantry. BUT you can finally control the degree of motion error with the lower cables and the algorithm to which it is being moved. Which brings us to the last factor of movement is the feed and release algorithm. This is something that I foresee either there being a calibration procedure down the road, available to fine tune based on vertical/horizontal or mill bit size or cable stretch which increases your accuracy. OR you will be tasked with making extensive motion tests with various scenarios like those listed above that allow you to monitor motor current and cable tensions to make your feed and retract algorithm more accurate. In the end of the day, this paragraph covers many of the subject mater surrounding router accuracy. I love that you have added the lower control cables and this will make this kind of router gold. And from what I've seen, its good to go. Youve done it, congrats. I just like talking shop/engineering and want nothing more than you to improve from the community input. I'm available if you want to bounce anything off me. @@BarSmith2
@@xLibelle Not at all! It's an excellent point. It's not a small thing at all. I couldn't agree more that it needed to get fixed and it would be a big concern if it hadn't already been done. One thing to consider is that we are using encoders to measure the belt's position AFTER all of the spool+gears assembly which is important because it means that we don't have to worry about things like backlash in the gears or that the spool of belt gets bigger as more is rolled up. It's a critical part of the precision/cost equation to not have to worry about those things because it means we aren't relying on having perfect mechanical parts. The encoder is measuring how much belt is actually extended and using that feedback to drive the motors. I agree about wanting to factor in the weight of the sled in the upright orientation. The reinforced belts are super low stretch so we can hit our goal tolerances without even factoring in the weight of the sled, but since it is a factor and we can account for it we should be able to do even better if we take it into account. That is very much on my todo list.
That ESP3D UI you edited looks slick!! The gcode visualizer looks good. Mitch's version has a pinch to zoom built in I think. If you added something like that it might help with your scaling. If people want to get a closer look they can. I know one of the guys is working on getting the FluidNC UI fork and the espui back in sync, hopefully after that we can get one of those visualizers in there. Super excited to see the progress. Looks like you are having fun, so many good ideas, exciting stuff!
I've updated to the latest version of Mitch's but I don't have the pinch zoom code. That's super cool I'll keep an eye out for that. Thanks for the tip. That would be a really nice addition
@@maslowcnc Maybe I need to double check, I thought it did, I could be wrong....I only use it to make sure it is the right file if I use an old one and see where my start point is.
Very cool the idea of just having anchors on a concrete floor. I wonder if the anchors could be just some weights that have a attachment point, so you could do different size work areas depending on the project.
I was wondering if 5 gallon buckets of water would weigh enough. Maybe they could stack together when not in use? We're going to see so many cool ideas for the anchor points I think
@@maslowcnc of course, there is a minimum weight to prevent sliding, but having some kind of metal spikes or maybe even a rubber pad below the weight would increase The effectiveness of the anchors. The spikes would probably have less slippage. I’m thinking maybe attaching some sawzall blades to the bottom of the buckets might work.
I am looking forward to this kickstarter more than any other I have ever backed. I've been wanting a Maslow for years. I too am an engineer, and I was seeing that the motors are shaky. Is that a result of mounting to the plate that is still flexible?
There is another comment on this video that I answered this in more detail, but basically it's because the other end of the motor shaft is not supported on three of the motors here. They will all be supported in the final version.
Awesome update, was great to see it in action. It's a bit tricky/pricey to get the DeWalt where I live. I can special order a D26204K (plunge/trimmer kit), but no return for change of mind or "doesn't fit" Could you do an update at sometime about the fitment and possibility of installing a different (i.e. Makita) router? Greatest admiration for what you're doing.
It is a little bit hard to tell in the pictures (DeWalt really needs to work on this), but I think that the D26204K might be the version which has the power cord coming straight up instead of coming out horizontal. It should still work, but the power cord the other direction is better. The Makita router is a SUPER popular request that I want to get to when I have a chance. I haven't done it yet so I don't want to promise anything, but it's high on my todo list and there have been some excellent discussions in the forums on how to make it work.
We are focusing on delivering to our KS backers right now, but we will reopen sales once we've done that. If you join the email list on our website we'll send you an email with a link as soon as they are available again.
I'm interested in the concrete floor anchors as well. I was thinking of some drop in anchors that can be removable when the machine is not in use so I can park my car in the garage. I'm guessing we can just use the carbide3d post in Fusion 360. Is that a correct statement?
There's actually a Maslow post already for Fusion360 and we'll probably get them to update it. But also yeah the carbide3d one would work just fine too. We're using GRBL for gcode interpretation so it will handle almost any gcode file, no particular post processing needed.
I know you’re not looking for copy editing on that sign, but I’m unable to resist: the rogue apostrophe above the "e" in "Chez" that’s probably trying to be a grave accent is not needed if it’s just supposed to be the French word "chez." From a graphic design point of view, it looks great, and if your buddy is named Chéz then I’m out to lunch.
Haha that also falls into the category of things that aren't my problem 😃...I just cut it. He is not named Chez tho so I'm pretty sure you are correct 😛
it is an interesting design but it actually isnt the first of this style. there was a kickstarter from Cubiio X that did this style too. They ran horizontal.
Yeah their design is pretty cool! It's a little different (slower, smaller work area...etc), but you are right that it is somewhat similar. I'm not sure if they've shipped them yet though. Generally we are still in the early days of figuring out what is possible with this kind of machine
@@maslowcnc I'm using the m2 frame. I think it would be great for you guys to use that frame as many people who are loyal to makermade already have that frame. Just a thought.
Gotcha, I haven't actually ever seen one of those in person (they're a totally unrelated company), but I don't see any reason that it wouldn't work. You might need to modify it slightly, but generally the requirements for the frame are pretty minimal, it really just needs to be a flat rigid surface and anything that meets those specs will work
So excited! I love the idea of anchor points on my garage floor.
Right!? I think that for the majority of people there is no need to build a frame at all (But we will obviously still support that option)
What a cool update. Nice to see a kickstarter coming together like this.
We're doing our best! The weekly updates keep us honest....and appropriately stressed
Super cool announcement! Really excited to continue to see progress!
Thanks!
Good job, Bar. Looks awesome. Can’t wait to make another weeping angel. 😂

Try big size, like printing concrete, I think it will work better in that context
I'm not sure I understand, do you mean replacing the router with a tube that prints concrete and making the whole thing huge?
I would totally be down with a maslowconcrete printer but I don't think that is in their plans.
