Planner_Bezier - Speed along the path - 5 years ago

Hi all, here is a simple question about the G5 experimental feature (Bezièr cubic spline interpretation). The feature actually implement the De Casteljau's algorithm, and If I have understood correctly this lead to an non-constant speed along the curved path. So, am I right about that? Thank you so much!

Double extruder, double BLTouch - 5 years ago

Hi All, I'm usign a cartesian printer based on Duet board and RepRapFirmware for Duet 2 V2.02. I was just wondering if it would be possible to mount two BLTouch, one for each extruder, in order to make the secondary nozzle independent from the probe calibrations (M558, G31) related to the primary nozzle. Thank you!

Re: Vector based printing (Marlin) - 5 years ago

Hi misan, thank you. Quotemisan The current way Marlin (and other firmware) handles G2/G3/G5 is by turning it into a sequence of straight lines feed into the planner. This is a very important aspect of the matter, and I've had the same pictures in my head while reading "planner_bezier.cpp" files. After all this may not be a problem, because ultimately you rely on motor's steps and their resolut

Re: Installing Marlin firmware for Prusa (i3 MK3) - 5 years ago

Thank you dc42 and Dust for your contribution! Quotedc42 Is there a design tool + slicer combination that can generate G5 commands, without the model being quantized into flat facets or straight line segments at some point and then back again? If there is, then I'll implement G5 commands in RepRapFirmware. If not, it seems pointless to me. About that it's dog chasing his own tail! We need to fi

Thank you Dust! QuoteDust If your updating a real mk3, then you need to use motherboard BOARD_EINSY_RAMBO It not a ramps anymore.... so there is no need to edit pins_Ramps.h Most of the config settings in prusa firmware have been consolidated into 1_75mm_MK3-EINSy10a-E3Dv6full.h I'm aware about that.

Re: Installing Marlin firmware for Prusa (i3 MK3) - 5 years ago

Hi Robert, thank you so much for your reply! This is the first time for me in compiling official Marlin for my original Prusa, so I have no earlier configuration files and I have to start from scratch. If I understand correctly I need, in broad terms, to: Download the last Marlin and Prusa i3 MK3 firmwares; Prepare development environment (as described here: ); Merge configuration.h, configura

Installing Marlin firmware for Prusa (i3 MK3) - 5 years ago

Hi all, in order to test some Marlin 2.0 experimental features on my Prusa i3 MK3 I need to properly configure and compile Marlin firmware for my printer, so I'm here to ask you which is the best procedure to follow. I think that trying to implement the desired marlin features into last official Prusa firmware is not the right way to reach the goal, but I'm open to your proposals Thank you!

Re: Vector based printing (Marlin) - 5 years ago

Quotegregsaun I would love to see a slicer able to use STEP files with real arcs instead of the triangles from STL Not only arcs, also Bézier curves in order to describe any curved shape or movement. Post-processing Gcode to parse and "condens" G1 into G2/G3/G5 commands it looks a kind of useless "reverse engineering" procedure me, considering that vector instructions are yet contained into STEP

Vector based printing (Marlin) - 5 years ago

Hi all, I'm experimenting vector based FDM printing using G2, G3 and G5 commands (arcs and Bézier curves), hand writing the GCode also for complex models, printing on cheap hardware (Prusa i3 MK3) and also on really high-end printers. During last months I verified that vector printing determines: a truly better surface finish; a lot less hardware vibration (especially printing with cheap hardwa

BLTouch - Probe accuracy and strange behaviour - Some tests - 5 years ago

Hi all, in order to check the accuracy of the BLTouch probe mounted on my machine, I've run multiple bed probing sessions while using two different BLTouch settings (M558). Specifically: Bed size: 800x400 mm. Number of probe points: 25. Probe area: 2100.0 cm². Bed temperature: 45 °C BLTouch settings 01: M558 P9 F200 H5 T8000 B0. BLTouch settings 02: M558 P9 F150 H5 R0.3 T8000 A5 B1. I've run 1

BLTouch and Heaters - How to use the M307 command? - 5 years ago

Hi all, in the config.g file, on my machine, I've found the string: M307 H4 A-1 C-1 D-1 This is good because I need to disable bed heating during probing moments, anyway the command does not seem to work (my machine indicate me when the bed and tool are heated on it's embedded screen.) So, I would ask you: How to check the bed heating while probing? How, precisely, M307 command works? I've che

Slic3r - Custom bed raster image - 5 years ago

Hi all, do you know if it is possible to use an image (JPG, PNG, ecc.) as print bed in Slic3r? The goal is to visually place with the desired precision the object (STL) on a paper-printed substrate. Obviously the photo/image of the substrate should be prepared to perfectly match the true bed print area (I yet have a camera system that is capable of taking picture and distort them to compensate s
