Re: Smoothieboard 2 Progress

Slightly offtopic, but do you know if anyone is working on an arm solution for "desk lamp" type articulated robots, like this one ? RobotArm.jpg I've talked to at least 4 different persons working on adding that to the Smoothie code, but I don't believe any of them have any public code ye...

Re: Smoothieboard 2 Progress

Is there a way you guys could use opto-isolators, or some other trick, to make it so that we can hot-swap a hot end? If I do that now, I run the risk of burning out the thermistor port. Would be nice if we could do this for manual work (swap hot end with probe, swap hot end with other hot end), as ...

Re: Smoothieboard 2 Progress

As a user with a slightly more than zero understanding of industrial controls (I work with PLCs, and CNC programming), I have an honest question here. If it is unsupported to change it and there is no explanation of it, what actual documentation do you have beyond "This is a thing, don't touch...

Re: Smoothieboard 2 Progress

Instead of a differential Step line, I would look at using use a differential Start Move line. Then the same signal can feed all the expansion boards. We plan on having the same step signal feed all the extension boards. The faster one gets the step pulse, the other follow it at a given ratio they ...

Re: Smoothieboard 2 Progress

1. Regarding the segmented/segmentless delta motion, people tend to concentrate on the error at the centre of a segment, which is tiny if the segments are short enough. However, the other factor involved is that at the boundary between segments, the head position has to be rounded to a whole number...

Re: Smoothieboard 2 Progress

Thanks, I had assumed that was what it was, since it was referenced as "segmentless delta". Also, the mechanical bits of most deltas are going to smooth out most of the movements anyways. Well some people do have extremely well built deltas where this question matters, but what I said app...

Re: Smoothieboard 2 Progress

Would someone explain what you mean by "segmentless delta"? I'm understanding it as the ability of the controller to accept a G2, or G3 command. I was given the impression that it wasn't implemented, in general, because very few slicing programs were implementing "arc fitting" t...

Re: Smoothieboard 2 Progress

Hey everybody, Arthur from the Smoothie project here, with a few comments First on the spec, 626Pilot has most things right, except the RAM/Flash : Smoothieboard v2 will have 264kB of RAM, and 8MB of Flash ( I think the values you posted are older ones ). That's 200kB more RAM than what we have now,...

Yes.

Also, on scripts, you can find those that were written for the S3D bug here : http://smoothieware.org/simplify3d

Re: Heuristic (AI) calibration for delta printers on Smoothi

or should add a parameter for the minimum move size. That's what other slicers do and it solves the problem completely. I was knee deep in Slic3r's code for part of december, and it takes a lot of care not to do what S3D does. It think any slicer worth the name should do that. Slic3r has a default ...

Re: Heuristic (AI) calibration for delta printers on Smoothi

Arthur, what makes the bug so difficult to quash? (Go full nerd - I've been a software developer for 30 years, I'll understand the write-up. ) g. First thing is : it's insanely difficult to reproduce. Same G-code file, same smoothie config, same way to interface it, same firmware, and sometimes eve...

Re: Heuristic (AI) calibration for delta printers on Smoothi

Hey. Just a few notes. A work around exists, but the main smoothie firmware dev refuses to accept it, Actually, the main smoothie dev came up with the hacky work around, after a lot of work by a lot of people to try to figure it out. And nobody is "refusing to accept it", it's available in...

Re: Smoothieboards unreliable - what new controller to suppo

Working on Smoothie v2 ! m I have a question about this. In another thread, someone very clever pointed out that you might implement a "Z probe" equivalent by measuring the current to the motors - if they stall, it goes up. I thought I could remember something about stepper drivers having...

Re: Smoothieboards unreliable - what new controller to suppo

I'm still glad I bought the smoothies, there have a been a few problems with them over the year and a half I've had them but they work great most of the time. I think I'm the only person driving a lathe with smoothie, and I haven't seen any 4 axis TAIG mills with smoothies either. The stepper curre...

Re: Smoothieboards unreliable - what new controller to suppo

As for getting upset, I think that's a normal response when you've been 1) shipped a bad board, 2) ignored by the seller, You have *not* been ignored by the seller. The seller has been unable to handle email recently. Those are two extremely different things. If I had access to their email box, thi...

Re: Smoothieboards unreliable - what new controller to suppo

It sounds like v2 is at least a year away, from what I have heard. We are not giving any deadline for this project ( because last time we did, we got people upset by not meeting it ). What I can say is, we have v2-pro proto boards soldered, we are working on the v2-non-pro design, and have started ...

Re: Smoothieboards unreliable - what new controller to suppo

As detailed in this thread , I bought two Smoothieboard 5XCs, and one of them arrived with two capacitors improperly soldered. One fell off the board on its own, and the other was so poorly soldered that it peeled off with almost no effort. The other capacitors were all solidly connected, so I know...
