Tim Schneiderandyw4z	b6bb1b92c9	Add Meltingplot vendor profiles (CHX 350 + MBL series) (#14756) ... * Add Meltingplot vendor profiles (CHX 350 + MBL series) Adds the Meltingplot vendor bundle with 5 printer models: - CHX 350 (880x422x943, RepRapFirmware/Duet) - MBL 133/136/308/480 (RepRapFirmware/Duet) Each model ships 0.4/0.6/0.8/1.0/1.2 nozzle variants. Layer height presets span 40-60% of the nozzle diameter and deliberately avoid heights that divide the Z screw lead evenly (CHX: 1204 ball screw, 4 mm lead; MBL: TR4x2 trapezoidal screw, 8 mm lead) so periodic screw error does not repeat as banding. All printers use 2.85 mm filament, so the bundle carries its own filament library (PLA, StoneFil, ABS, TitanX, ASA, PETG, PA6 CF HT, STYX 12, PP 9-2, PET-CF15, Extrudr PLA NX2 Matt, Igus iglidur J260) with the 2.85 mm diameter pinned once in the vendor-local fdm_filament_common base. Machine limits mirror the printers' firmware configuration; machine limit emission is disabled so the values only feed the time estimator. * Add per-nozzle volumetric flow limits and nozzle size in filename Cap filament volumetric speed per nozzle (0.4: 14, 0.6: 20, 0.8: 26, 1.0: 30, 1.2: 40 mm3/s). Filaments whose limit exceeds a nozzle's capability get a nozzle-scoped child profile that only lowers filament_max_volumetric_speed; filament_id is inherited so all nozzle variants remain the same material. Also include layer height and nozzle diameter in the g-code filename. * Set CHX 350 machine time cost to 5 EUR/h * Inherit Meltingplot filaments from OrcaFilamentLibrary generics Per the profile creation guide, vendor filament profiles now inherit from Generic * @System instead of vendor-local fdm_filament_* copies. Each profile carries only Meltingplot-specific deviations plus the 2.85 mm filament diameter; the seven local fdm_filament_* base files are removed. Deliberate pins where the library default would change tuned behavior: - PLA/ABS/TitanX keep filament_max_volumetric_speed 20 (0.6 nozzle cap) - ABS/PET-CF15 keep close_fan_the_first_x_layers 1 - STYX 12 sets required_nozzle_HRC 0 (unfilled PA12, density 1.02) * Remove Meltingplot StoneFil filament profile * Meltingplot ABS: use library fan settings * Meltingplot TitanX/ABS: use library fan and nozzle temperature settings * Remove STYX 12, PP 9-2 and Igus iglidur J260 filament profiles * Meltingplot ASA: use library fan_max_speed * Derive per-nozzle volumetric speed caps from physical limit formula Caps now follow V = 34*d * m / S: the 34*d limit line calibrated on Micro Swiss Volcano plated copper at 2.85 mm, material factor m from the OrcaFilamentLibrary generic ratios (PLA/ABS/ASA 1.0, PETG 10/12, PETG-CF 11.5/12, PA-CF 8/12, PLA Matte 11/12), safety factor S = 1.25 covering batch/moisture/wear/diameter tolerances. Each material base now serves the 1.2 nozzle at its maximum cap; children @0.4-@1.0 lower the cap per nozzle. Machine variant default_filament_profile entries point at the matching preset. * Scale slow_down_layer_time per nozzle from bead cross-section Minimum layer time follows the derived cooling rule: heat per layer scales with bead cross-section (layer height x line width), so the 0.8-nozzle-tuned values are scaled by q(d)/q(0.8) using each nozzle's standard preset geometry. Bases carry the 1.2 value, children @0.4-@1.0 their nozzle-specific value. * Meltingplot: lift Z above the print before the end macro Add a G90 / G1 Z{min(max_layer_z + 5, printable_height)} F600 move at the start of machine_end_gcode, before M98 print_end shuts the printer down and parks it. Besides clearing the part, the explicit Z coordinate lets the Duet file-info parser pick up the object height. * Meltingplot: cap default layer height at 40% of outer wall width A 45 deg slope shifts each bead outward by exactly one layer height. With the Slic3r bead model (rectangle (w-h) x h plus half-circles of diameter h) the flat contact band to the layer below is w - 2h, so the maximum self-supporting angle is atan((w-h)/h). Support cannot compensate: the stair tread at 45 deg is only h wide, far below one support line width, so no support line ever fits underneath a single step. All ten machine variants defaulted to h/w = 0.455..0.524, i.e. at or past the h/w = 0.5 point where the flat contact vanishes. The 0.8 nozzle default (0.44 mm at w = 0.84) reached atan(0.4/0.44) = 42.3 deg and failed on 45 deg slopes even with support. Default presets now satisfy h <= 0.40 * outer_wall_line_width, which leaves one third of the bead's flat underside in contact at 45 deg and puts the geometric limit at 56.3 deg. To keep the defaults on sensible ladder rungs, outer wall width is widened where it was the binding constraint: chx_small 110 -> 115%, chx_large 105 -> 110%, mbl_04 105 -> 115%. Ladders are unchanged; the thicker rungs stay available for parts without steep overhangs. * Meltingplot PLA: raise slow_down_layer_time by calibration factor 1.5 Print feedback on CHX 350 with a 0.8 nozzle at 0.44 mm layer height showed curling at the retraction points with the derived value of 25 s. There is no cooling headroom left to trade: fdm_filament_pla pins fan_min_speed = fan_max_speed = 100, and additional_cooling_fan_speed is inert because no Meltingplot machine enables auxiliary_fan. Minimum layer time is the only remaining lever; 35 s prints cleanly at that geometry. The cross-section rule only fixes the ratios between nozzle sizes, so this is a calibration of the PLA anchor itself: both PLA ladders are scaled by 1.5 (Extrudr 9/20/38/56/83 s, Meltingplot PLA 8/17/30/45/66 s for 0.4/0.6/0.8/1.0/1.2). The Extrudr base fan_cooling_layer_time goes 60 -> 100 so the 1.2-nozzle value stays below it. Other materials are left unchanged - only the PLA anchor has a real counter-example so far. * Meltingplot: drop layer heights that cannot print 45 degree walls A preset whose layer height exceeds ~45% of the outer wall line width has less than ~6 degrees of reserve on a 45 degree wall (max self-supporting angle atan((w-h)/h)), and support cannot compensate because the 45 degree stair tread is only h wide - far below one support line. Those presets are not usable in practice, so shipping them only invites failed prints. Removes the 22 rungs above h/w = 0.45 and prunes them from the vendor index. What remains per nozzle (default first): CHX 350 0.4: 0.18 | 0.6: 0.24 0.28 | 0.8: 0.32 0.36 1.0: 0.44 0.48 | 1.2: 0.48 0.56 MBL 0.4: 0.18 | 0.6: 0.24 0.28 | 0.8: 0.36 0.34 1.0: 0.44 0.48 | 1.2: 0.48 0.56 The 0.4 nozzle keeps a single rung: 0.20 mm would qualify (h/w = 0.435) but divides both screw leads evenly (4/0.20, 8/0.20) and stays excluded by the Z-artifact rule, and 0.22 is already at 0.478. Also corrects the MBL 0.8 default to 0.36 mm, which at w = 0.92 sits at h/w = 0.391 and therefore still satisfies the stricter 40% default rule. * Meltingplot: require 5 degrees of reserve on 45 degree walls Replaces the two separate thresholds (h <= 0.40 * outer wall width for defaults, 0.45 for ladder rungs) with a single requirement stated on the design constraint itself: every shipped preset must reach a_max = atan((w - h) / h) >= 50 deg i.e. 5 degrees of reserve on a 45 degree wall, equivalent to h <= 0.456 * outer_wall_line_width. The default is simply the thickest rung that passes. The 11 degrees the 40% rule produced were more margin than the failure mode warrants, and cost throughput for no return. For calibration: across 940 machine defaults from 60 vendor bundles in this repo, the median reserve is +1.8 deg, 71% ship less than 5 deg, and 8% cannot geometrically produce a 45 deg wall at all. Adds the rungs the relaxed threshold makes available - 0.30 (0.6 nozzle, both series) and 0.38 (0.8 nozzle, both series) - and restores the 0.30 mm MBL preset removed in 5b4862b3 with its original setting_id. 0.20 mm on the 0.4 nozzle and 0.50 mm on the 1.0 nozzle would also qualify but stay excluded because they divide both screw leads evenly. Defaults are now (0.4/0.6/0.8/1.0/1.2) 0.18/0.30/0.38/0.48/0.56 for both series, at 50.2 to 57.3 deg. The 1.2 nozzle deliberately keeps 0.56 rather than the 0.60 the rule would allow: solidification time scales with h^2 and bead weight with h*w, so the largest nozzle is the one that should not sit on the minimum. * Meltingplot: disable precise wall by default Precise wall was inheriting OrcaSlicer's global default of true. Disable it bundle-wide in the vendor process root so it applies to CHX 350 and all MBL models. Note it was already ignored on the CHX small-nozzle branch, which uses the inner-outer-inner wall sequence. * Meltingplot CHX: raise max extruding acceleration to 6000 The 4000 limit silently clamped the profiles' 6000 values for default and inner wall acceleration, since GCodeWriter caps print acceleration against machine_max_acceleration_extruding regardless of emit_machine_limits_to_gcode. Raising it to 6000 matches the X/Y limits so the configured values are emitted as-is. The firmware's own M201 still governs what is actually driven. * Meltingplot PA6 CF HT: raise part cooling floor to 40% Sharp 90 degree corners were washing out layer by layer while straight walls and overhangs printed cleanly. Overhangs are fine because overhang_fan_speed forces 100% regardless of layer time; everything else fell back to fan_min_speed, since at the layer times seen in practice neither branch of the layer-time fan interpolation applies. Raise fan_min_speed to 40% and set reduce_fan_stop_start_freq so that floor is actually applied instead of dropping to zero. Also lower the auxiliary fan to 40% and raise the overhang cooling threshold to 95%, matching the values validated on the print. * Meltingplot: re-mint filament ids with orca_id_tool Upstream now requires every filament_id to be a minted "OF" id derived from the (filament_vendor, filament_type, name) triple and recorded in scripts/filament_id_snapshot.json. The hand-made ids this bundle shipped with (MPFPLA0, EXTNX2M, ...) were rejected by orca_extra_profile_check. Regenerate them with "orca_id_tool.py --generate --vendor Meltingplot" and record the result with --update-snapshot. No setting_id changed, and the ids were never released, so no existing project file refers to them. * Meltingplot: normalize bundle for updated profile checks Drop obsolete keys (silent_mode, adaptive_layer_height, tree_support_with_infill) and rebuild the vendor index in canonical order, as orca_profile_tool.py normalize / update-index write them. * Meltingplot: list per-nozzle filaments in default_materials The unsuffixed filament presets only cover the 1.2 mm variants, so the 0.4-1.0 mm printer presets had no compatible entry in their model's default_materials. The validator's check_printer_default_materials rejects that, and load_installed_filaments would auto-install no filament for those variants on first run. Name the @0.4/0.6/0.8/1.0 nozzle presets alongside the base ones for PLA, PETG, ABS and ASA. --------- Co-authored-by: yw4z <ywsyildiz@gmail.com>	2026-09-22 00:14:33 +08:00
