What is ARMS anyway
Them things hanging off your shoulders dog! duh…
Sorry, I can’t help myself when it comes to a good dad joke. It’s actually an acronym so you have it in the plural ARMs
Advanced RISC Machine
It’s just basically the type of base architecture for the processor. The Raspberry Pi is based off a ARMv6 32-bit processor. The Atmega 2650 (Arduino mega that makes up the rambo board) is an 8-bit RISC (reduced instruction set computer) processor. It really has to do with how instructions are carried out within a given clock cycle and how memory is allocated. Pic micro-controllers are based on CISC (complex instruction set computer) architecture–another example. Give it a google, it’s pretty interesting stuff. I know this is a vast oversimplification–please don’t yell at me.
This lulzbot forum rocks, period, admin or no admin…so let’s not go there.
YES! but I’m going to anyways. Else I’ll just stare at my printer. Does anyone else get hypnotized when they are printing?
@percet
Totally agree, couldn’t be stated better. I see you’re creeping up on that century mark. Think you can hit it before Orias?
I know this is a TLDR type post–borderline novel–but read on if you like. I’ve broken up my responses to be as succinct and explicit as possible to each one.
See Tom’s review on smoothie.org for why the 3D community needs to abandon Arduino
Gotta link for that dog? 'Could hit me back for at lest one of the links I’ve thrown at you.
I don’t want it to get mistaken that I was knocking smoothie. I think it’s awesome and if I didn’t have so many “irons in the fire”–as they say–and some extra money I would be building a scratch TAZ with a smoothie board just to get some more experience with running more complex coding on higher level processors. The work on the smoothie project is creative, pioneering, and extremely impressive. But to say that Arduino should be abandoned–personally–I think isn’t safe to say and I don’t think anyone at smoothie would explicitly say it. But smoothie developers have spent a lot of effort on the smoothie project and want it to be adopted. So its reasonable for them to say their product is superior–they have to back it fully, who’s gonna buy something from a developer that says “this is pretty sweet but not really necessary”.
The answer to your last question “Why do you need more than an 8-bit processor to control a 4 or 5 axes machine anyways?” is the key to enlightenment, I hope you find it.
I probably won’t I can barely get through the day without losing my car keys. However, I can’t say that it is totally necessary to run this 3D printer on more than an 8-bit RISC chip. I currently print on my TAZ with a .35mm nozzle (waiting for a .75mm) at 175mm/s–100mm/s on the perimeters and bottom–with the acceleration set to 2000mm/s^2. “Lies, damned lies and statistics” am I right? I don’t have any problems with the processor not keeping up. I’m not sure the TAZ can physically go much faster nor at what speed and complexity does the AtMega2650 start to reach its limit. If the TAZ reaches a speed limit due to physical constraints then getting faster electronics won’t make it go faster–just break faster after you crank all the settings up. Besides my favorite part about using small processors is that you become forced to really know the chip and squeeze everything you can out of your software–no memory or clock wiggle room and lots of machine code.
Sure I could send you guys a personal email, but how does that benefit the community? IMHO Lulzbot needs to get to EVERY thread.
Percet drives a tack in this.
I’m going to use my Arduino community example again as a metric to get an idea as to how big this forum is and yet how impossible the task you are asking is. As of writing this the Arduino forum has 2,046,984 posts in 259,387 topics by 256,144 users even if they had 250 moderators–which they definitely do not–each one would still have to comb through 1,000+ topics. Given that there are 8659 posts in 1337 topics by 1381 users in this forum it is relatively small–which is fine–but even with 5 admin–Lulzbot has 2 it seems–it would still be almost impossible to be able to keep up with every single thing that is going on–“Lies, damned lies and statistics” fffuuuu… twice in one post. Here’s a challenge, make a meaningful post on 250 of the most current topics within a 7 day time span and then respond to any reply that you get from your initial posts within another 24 hours–anyone would stop re-answering questions–I know I can’t do this, no way no how. I think a forum or anything that grows out from a single entity is like raising a child, you give it everything you have and do everything for it but eventually that bird is gonna/has to fly off on its own.
Sure there’s a lot of duplication, stupid questions (like mine), and questions that have been answered before a 100 times (like some of mine),
I agree with this completely but it doesn’t/shouldn’t have to be this way. This is why it took me a week to even touch your OP. No one is going to waste their valuable time to re-answer questions except me–sometimes I just can’t keep my mouth shut.
I don’t have time to surf the web all day, that’s why I read forums like this one it’s a lot faster to ask questions
Bro, you waited 6 days for me to come along and spend 10 minutes to search google for you. I don’t want to be mean about it but dude…that’s some fu€ked up $hit right there.
I also read this forum almost every day, and pretty up to date on most of the current issues that concern me, the new hot end being one of them
Then how did this question and response happen?
Also it would be really nice if I could just buy the new hotend separately and print the other parts as needed to save some money; but currently Lulzbot only offers the complete extruder and not the standalone hotend.
Damn dog, you gotta get off your box and google around a bit. Where do you think Lulzbot got the hex head from in the first place?
Right here, 50 big ones and your problems are solved. It even comes with the mount, heater, & thermistor.

but isn’t that what open source is all about
He’s my take on what I think open source is all about. There is no such thing as a “dofor”–I’ll do this for you–in the open source world (maybe every once-in-a-while). Most things you at least have to make an honest attempt at doing/fixing it yourself first. Without that there is nothing for anyone to build off of. Giving out valuable and useful knowledge to help solve a problem–yours or someone else’s–to make something better/easier is the hidden currency of the open source realm. This could be as basic as letting someone who is having a particular problem know you’re in the same boat even if you are not exactly sure how to fix it.
Here are some of my favorite examples of great threads on this forum. I hope this illustrates my point better. Let me know if there is a thread that should be in here.
Adjustable heat bed - glass mount I’m in this one and the problem may not even have to do with the printer
HOT END DEAD. (FIX IN PROGRESS, GREAT CS) Super pertinent to your #1. Wait! WTF! admin active on the weekend!?
PEI bed surface 6 months strong and given the TAZ5 just dropped I bet it will get some more traffic.
UPDATE-Video of Taz Auto Bed Leveling Mod Based on Taz Mini - #6 by Techsavvy34 Think this will be on the TAZ6? Coolest grassroots upgrade I’ve come across so far.
And a not so great thread for comparison.
Support guidance needed.... Here is a post of a few people putting in a good amount of effort to help someone in a unique situation only to have the OP bail. I wonder if she ever got it to work out? If the OP posts another question will anyone help her out again? It amazing how the people that can be the most helpful on a forum will never respond to people that do this.
Do I have to keep going? I feel like this gets my viewpoint across.
and isn’t that one of Lulzbot’s core beliefs?
I’m pretty sure Lulzbot does a good job summing up their beliefs in the statement below but I’m not really into the habit of speaking on others behalf. And I would like to mention that the hexagon hotend has been a work in progress for almost year now. It came to be through collaborations between Lulzbot and the community and if the community didn’t push for that specific high temp hotend then the current Lulzbot lineup could have just as easily been donned with an e3d-v6 or a j-head MK-IV. Have a search on the forum, the hexagon nozzle is a good example of what I think open source and community directed modification is all about.

The point I’ve been trying to make–since my first post–is you should do a little homework before you go asking questions. It’s a general common courtesy to those that you are asking to help you out. Every one of your original questions was easily answerable with a quick search–which you could have found with a little effort on your part or they were already answered somewhere else–which you could have found with a little effort on your part. You also start talking about how things should change or already be different without evening showing an attempt to do anything to create this change–which you could do with a little effort on your part. See where I’m going here? My favorite part about the open source model is if I don’t like some aspect I change it and I let others know about it just in case they might want to change it too. If you go down the road your on you may not get much future help and it could possibly only cultivate resentment from the community. Thus, destroying one of the most powerful aspects of the Lulzbot product for you and everyone else. This in earnest I do not want to happen because I now know a dude with over 40 years of experience with RISC processors that could probably write some slick firmware updates to fix this little issue that’s been out there for a little while now.
I have switched back to the single original extruder for ABS and a single flexystruder for Ninjaflex, but just mount whichever one I need to print, setting the other one aside but still connected > so the dual extruder firmware doesn’t complain> .
