Hello JonathanThompson, and thank you for your long reply, that will allow me to clarify my post. QuoteJonathanThompson As a software engineer myself also with embedded experience I find myself wondering: are you wishing to do all this on your own because of the typical "Oh yeah? I cancdo it better!" common to people writing code to do something that already has other readily available solutionsby Briztou - General
Nicer ! I'll take a closer look at this firmware, thank you :-) Briztou.by Briztou - General
Quotedc42 Have you looked at RepRapFirmware? The current build for the Duet WiFi/Ethernet supports up to 12 motors and 9 axes. The firmware could be compiled to support more drives and axes readily, if you have the hardware to support them. Hey dc42 ! Nice ! I didn't know this firmware ! Do you know if he can be adapted to non-cartesian geometry? Quotedc42 IMO if you really want to controlby Briztou - General
Quotecwaa Why not just buy a Smoothie board? Hi cwaa, If you just talk about electronics, the first reason I would invoke is the price (I'm a broke student ;-) ), but in addition to this, SmoothieBoard allows the control of (if I'm correct) at most 5 stepper motors, and I currently need 9 for the printer. Moreover, while I'm developping, I need a more flexible board, and RAMPS are sufficientby Briztou - General
Quotecozmicray It is unclear if TRACER is: hardware electronics firmware software Your mention of RAMPs seems to say this is firmware on a Mega arduino? Hi cozmicray, Thank you, I realised that I had employed the wrong word (my english aint perfect :-) ) TRACER is a firmware, with a stepper control module. You could see it as a framework (a core? ). It provides functionnalities, like thby Briztou - General
QuoteVDK The tool-selection could be an "offset" on the rotating tool-head ... the tangential moving vector could be calculated from the last to the next position while importing/generating the G-code or "on the fly" before executing to the next move ... What you may need is manipulating an abstraction layer, selecting your command coordinates (x, y, z, etc...) and the carriage you want to moveby Briztou - General
Hi VDX, Thank you for your reply, This kind of CNC fits perfectly in the controller's goal. More test are required to verify the speed regulation in non-cartesian systems, but for instance it sounds good. Nevertheless, the longest part would be to build the software, according to the machine. Do you have plans already? Thanks, Briztou.by Briztou - General
Hey !! My name is Raphaël Outhier, and I am a french developper, so before I begin, please excuse my approximative English. I am a new member of this forum, so let me introduce myself briefly. I am a french engeneering student, in embedded systems. I own a reprap for around two years (an OrdBot Hadron), and I have spent a lot of time improving its performances. For the last year, I have beenby Briztou - General
