How long is your transmission line? What VDD level are you using? Have you tried to terminate the A/B lines with resistors?

I'm getting noise only when magnetic field is not strong enough (>0.3mm...

That is definitely faster than your Taig! :)

I really depends on how precise you want it to be. They send strips in rolls and able to maintain 10um per meter accuracy just fine because the rubber magnet is bonded to a 0.3mm stainless steel base...

They can send you one 300mm sample free of charge: AS5000-MS10-300 / Magnets / Magnetic Encoders / Products / Home - austriamicrosystems AG

Getting longer continuous pieces will be a major...

Did you get the proper magnet strip from Austrian Micro along with your AS5311 eval?

We want pictures!

Looks very interesting. Please try to fit that rotating head and I'll hook you up with the software. I do handle automatic feeders through TTL I/O's or serial port commands.

These guys make interesting linear motors at reasonable prices (below $1K/axis) with built-in magnetic encoder: Bonmet Shenzhen CNC Equipment Co,.Ltd

For that same reason I would highly recommend keeping software in closed source domain.

On the other hand, developing own linear motors and drives would not stop competition from copying them....

Stewi - before we go multi-gantry or multi-head, we need to nail down the closed loop positioning. This is something that is totally lacking in sub-$100k machines and can greatly improve reliability...

Let me join the discussing if you guys don't mind. I seriously believe that there is a fairly large international market for a decent desktop PPM under $15K, which is curretly occupied by madell etc....

Stewi - I see in daedalus thread you are talking about "...re-focus on a small machine, likely single head, capable of 0201 to BGA, vision system, some feeders for under $10k". That is something I...

Stewi - that's a great idea! Of course I'm interested.

What performance targets (CPH) do you have in mind? What market segments are you looking at? Competing with SIPLACE could be a little bit...

@speedydumpster - thanks for the nice words!

Seeing the limitations and clearly horrible implementation in some low cost PPM software is what led me to the development of my own. The final straw...

Brad, yes, I'm planning to optimize the kinematics quite bit. What you are proposing is possible with some caveats. First I need to confirm the accuracy of the alignment algorithms with objects being...

Hi Brad - welcome to the thread!

I should let everybody know that I'm using your KMotion_dotNet.dll in my project. It greatly simplifies things and was one of the reasons why I picked KFlop as a...

That's what I thought as well, but also heard many times a machine being called a chip shooter to designate a particular machine in an assembly line where there is also another machine(s) that is...

That's a valid suggestion. At this stage I simply need something that works out of the gate. The complexity of robust vision algorithms is such that it will require some significant amount of time to...

Looks great. Can that vacuum generator also provide blow off air? It looks like their larger units do. You definitely need to make blow off air pulse at high placement speeds.

Still going with the...

I don't mind at all. You are making a very good points and I really like the idea of bringing the development back. Also love the concept of machine stacking. I think it can be applied to a small...

This is a very good and timely suggestion, Nails. Thanks for chiming in. It is true that I do know my monster machine in and out but a new user may be simply scared to run even a simplest homing...

I saw that bag of nozzles and was seriously considering it. Question is what to do when the bag runs out. As far as I understand, those tiny things are very fragile.

Thanks a lot for the kind words and great feedback! Keep it coming!

@guru_florida:
The Gerber converter idea is still up in the air. I know that most of the industrial machines have it and...

I'm not sure I understand the question. What gray bit? which second?

It has been quiet here lately and I think I needed to post another video
This time it's a shaky teaser of the PPM software that I've been working on. It's almost ready for beta testing, just needs...

Here's an opening post in the thread that I would like to dedicate to the discussions around the software package that I'm working on.

First of all, the bad news. While the main idea is to make...

Good progress, stewi! Is that gearmotor 12mm wide? Would it still fit?

What are your plans for the driving electronics? Do you want the feeers to be controlled individually with single-ended TTL...

Guess I will attach a needle and have some more fun with microstepping tonight.

Nope, no technical info or source. I just bought a bag full of motors on ebay for my experiments with my auger dispenser.

Can-stack motors should give you 5 rev/sec easily without gearing, as...

Forgot to mention that Mariss is probably right about the usefulness of fine microstepping. In most applications, the motor won't be able to hold its intermediate position if it faces some meaningful...
