Feature / Vertical plotter #293

Closed alexiscz closed 7 years ago

alexiscz commented 7 years ago

Hi guys,

I don't know if someone already tried to did that but I am currently trying to build a vertical plotter running on raspberry bi and using the EBB board.
EBB board is really a nice product and I am pretty sure it will be a nice use case to build a vertical plotter with it. I am trying to build something generic so your inputs are very welcome.

What I am currently doing :

Let me know if you have other ideas.

Thanks,

A

I should note that there are many types of vertical plotters. Some of them are driven as XY, some are driven as (a+b,a-b), and some are driven in yet other ways. I think that what you are referring to here is a vertical "hanging-V drawing machine" -- but the "vertical" part of it is neither necessary nor sufficient to describe what it is that you are after.

Hey Oskay you are in all repositories ;) (cf. CNCserver) I forgot this information, but you are right I am referring to a vertical hanging drawing machine. This is why, as we have already discussed on the cncserver repository, I would like to add some functions to convert points from a cartesian system to a polar system.

I imagine that this should be done within cncserver, not robopaint. If cncserver supports this type of motion with an .ini file, then Robopaint support is trivial.

Yup :+1: We've discussed it a bit and with some kind of consensus there, can make it a feature. PRs are always welcome of course, though development is pretty slow while I'm in the process of moving. Might just have a bugfix release out soon, but no real movement on features. I'm going to close this for the sake of housekeeping as support lies entirely within the realm of cncserver (it simply exposes the aspect ratio and a 2D drawing surface to RP and RP doesn't care how it manages to do that).

Agreed 100%. Thank you, @techninja.
